NP-View is designed to run on a Windows 10 or Windows 11 with a recommended configuration of a 10th Gen Quad Core Processor and 16GB of RAM.  This configuration should be sufficient for processing large data files up to 500,000 lines.  Simultaneously loading and analyzing multiple devices with larger configuration files will maximize the use of available system resources and additional RAM may be required.

Installation Process

• Sign up on the Portal website to download the latest version of NP-View Desktop and to download a license key.  A SHA256 checksum is supplied with each download.  You can calculate the checksum on the files you download to verify the integrity of the files:
  • Windows Powershell: Get-FileHash /the/full/path/to/your/filename.exe | Format-List
  • Linux: sha256sum /the/full/path/to/your/filename.Appimage
  • macOS 11: shasum -a 256 /full/path/to/your/filename.app
• Windows 10/11:
  • Launch the Windows installer with a double click.
    • User may need to adjust UAC (User Access Controls) depending on security settings.
  • The only dependency required on Windows is .NET framework 4
  • Once installed, NP-View will automatically launch.
  • Allow ports for private/public network if prompted.

NP-View has been designed to run offline, which means that the network connections attempted towards a public NTP server, the local DNS server, and the Network Perception update server are optional and do not affect the system if the internet is unavailable. More information on configuring NP-View can be found here.

NP-View Server has been designed to be easily installed by a single person who has moderate Linux skills. This article provides step-by-step instructions on the installation process, which includes:

1. Provisioning a server
2. Downloading NP-View server
3. Installing NP-View server
4. Installing a SSL Certificate

NP-View is accessed through a web browser (Edge, Chrome, Firefox) running on a modern operating system (Windows 10 or later, macOS 11 Big Sur or later, Ubuntu 20 or later) with a recommended configuration of a 10th Gen Quad Core Processor and 16GB of RAM.

Provisioning a Server

The following table documents the CPU, memory, and disk requirements based on the number of network device configuration files monitored by NP-View server:

Greater than 1,000 devices please contact support to discuss requirements.

Recommended as the minimum for most Professional Server users.

Note: loading and analyzing devices utilizes the majority of the CPU and Memory capacity.  The higher the server capacity and the faster the CPU, the faster devices will load and be analyzed.

Network ports used by NP-View server

The following ports are used by NP-View server.  Please ensure these ports are open on your firewall for proper communication.

Required ports:

• TCP/22: SSH server to provide secure console access to the NP-Live server
• TCP/443: access to NP-View Web UI through HTTPS
• TCP/8443: access to NP-View connectors Web UI through HTTPS

Optional ports:

• TCP/80: access to NP-View Web UI through HTTP
• TCP/389: access to Active Directory / LDAP for LDAPv3 TLS
• TCP/445: access to NP-View SMB Connector
• TCP/636: access to Active Directory / LDAPS for TLS/SSL
• TCP/8080: access to NP-View connectors Web UI through HTTP

Firewall Rules

The source IP should be the client workstation that will access NP-View and the destination IP should be the NP-View Linux server.

Downloading NP-View Server

Sign up on the Portal website to download the latest version of NP-View server and the license key.  A SHA256 checksum is supplied with each download by clicking on the “show checksum” link.  You can calculate the checksum on the files you download to verify their integrity:

• Windows 10/11 using Powershell: Get-FileHash /the/full/path/to/your/file/name/extension | Format-List
• Linux: sha256sum /the/full/path/to/your/file/name/extension
• MACOS: shasum -a 256 /full/path/to/your/file/name/extension

Installing NP-View Server

NP-View server is a Linux application. It can be installed on a virtual machine or physical hardware. There are 2 package formats available:

• NP-View Virtual appliance (~2GB OVF) that works on all major hypervisor with support for the .vmdk disk format (e.g., VMWare ESXi).
• NP-View Linux installer (~600MB) that works on all major Linux distributions on which Docker can be installed

The NP-View OVF uses Ubuntu Server 22.04 LTS or later. Root access is provided (see the text file provided with the .OVF) so the operating system can be periodically updated. This option should be used for new installations. The NP-View Linux installer is used to update NP-View on an existing system or for a new install on a Linux server.

Note: Network Perception does not recommend running NP-View in a double virtualized environment (Linux VM encapsulated within a Windows VM) as the operation of connectors, notifications and external interfaces can be unpredictable.

Option 1: Using the NP-View Linux Installer

Once downloaded from the portal, follow the steps below to complete the install:

1. Move installer to server – This may require ssh or other user account permissions
   
   1. Place the file in a location you can access from the terminal
   2. /tmp – this is a temp folder available at the root directory
   3. /opt/np-live – this is the default NP View server root directory
2. You can use the “ls” command to see what is in your current directory
3. Log into the terminal or use SSH (Putty, PowerShell, etc.) into the Linux server
4. Set root level permission with the command (this will allow you type commands without adding “sudo” to each command)
   • sudo -I
5. Navigate to the directory in which the NP-View Server Linux installer was placed
   
   • Use the ls command to verify file is in this directory
6. Run the installer with the command (Docker must be installed before this step)
   
   • Example: sh NP-View_Full_Filename.sh (example: NP-View_Server_Linux_4.0.5-add6)
7. The installer will begin by checking for a running instance of Docker and internet connection
   
   • If Docker is not installed and running the installer will stop and you will have to manually install the latest version of Docker before continuing
   • If an internet connection is available and Docker isn’t installed, the installer will automatically download and install the latest version of Docker
   • If an internet connection isn’t available but Docker is installed, the installer will continue offline (Most Common Scenario)
   • If you are installing NP-View Server on Red Hat Enterprise Linux, use the following commands to install docker:
     
     • yum update
     • dnf config-manager –add-repo=https://download.docker.com/linux/centos/docker-ce.repo
     • dnf install –nobest docker-ce
     • systemctl disable firewalld
     • systemctl enable –now docker
8. Follow the prompts during installation
   
   • Prompt to continue with offline installation
   • Prompt for default directory (/opt/np-live) We recommend keeping the default directory but it can be changed if preferred
     • Note: If the default directory is changed, then it will need to be edited for each new release during the installation
9. There will be a message once the installation is complete
10. Launch a browser to navigate to the NP-View User InterfaceExample of transfer with WinSCP:
    • Load WinSCP – It should default to this screen:
      

1. • Default “File Protocol:” to SFTP
   • Fill in Host name, User name, and Password.
     • Host name would be the same as your NP-View Server IP Address
     • User name and Password are the same as the sudo credentials you use to log into the NP-View Server terminal.
   • Find the NP-View Linux Server Installer file in the left window. Then in the right window from the “root” select the “tmp” folder. Once you have completed both steps then click “Upload”.
     

1. • Click Ok to complete the transfer.

Option 2: Using the NP-View Virtual Appliance

Once the Virtual Appliance OVF file has been downloaded from the portal, follow the steps below to complete set up:

1. Extract the .zip archive (right click on folder and choose extract all)
2. Import OVF into hypervisor
3. Update CPU/Memory/Disk Space to meet requirements stated in KB in the hypervisor settings
4. Open README.txt from extracted folder for credentials
5. Launch the appliance and log into terminal using credentials in README.txt
6. NP-View Server shell script will guide you through updating the NP-Live password, the root password, and to reset encryption keys
7. Once complete the NP menu will appear indicating the server is ready to use.
8. Launch a browser to navigate to the NP-View User Interface

Note: A static IP may need to be configured before utilizing the user interface.

Installing a SSL Certificate

NP-View listens on both port TCP/80 (HTTP) and TCP/443 (HTTPS). For HTTPS, it uses a self-signed SSL certificate by default. Users can also provide their own SSL certificate by simply copying a valid .pem file into the NP-View db folder.  If using HTTPS, the best practice is to disable HTTP or forward HTTP to HTTPS.

The following command can be used to generate a valid .pem file:

openssl req -new -x509 -days 365 -nodes -out cert.pem -keyout cert.pem

To learn more about generating your own SSL certificate, please visit python documentation.

Please note that .pem file should include both the private key and the full certificate. If you received the private key and the certificate as two or more separate files, you can concatenate them into a single .pem file.

Setting the Virtual Appliance Time Zone

By default, the Virtual Appliance install creates the file `/opt/np-live/local-settings.yml`, set to America/Chicago.  This file needs to be updated to reflect your local time zone.  To change to a different time zone, log into the server using SSH and become root with the command sudo -i. You can then perform the following updates.

Update TZ= to a value from timedatectl list-timezones

version: '3.4'

x-environment-tz: &timezone    

     TZ=America/Chicago

services:  

      manager:    

           environment:        

                 - *timezone  

      report:      

           environment:        

                 - *timezone  

     webserver:      

           environment:        

                 - *timezone  

      redis:      

            environment:        

                 - *timezone  

     monitor:      

           environment:        

                 - *timezone

Once you have set the new time zone, you can restart NP-Live with the command /opt/np-live/stop_NP-Live.sh  and then /opt/np-live/start_NP-Live.sh

Additional Installation Information

Improving NP-View Server Performance

Please reference minimum requirements, the higher the resources the better the performance.

Troubleshooting Disk Space

If a server upgrade or restart fails due to lack of disk space, please perform the following clean-up procedure:

1. sudo rm -f /opt/np-live/db/log/system/nplive.log.*
2. sudo docker system prune –volumes
3. sudo rm /opt/np-live/docker-compose.yml.backup

NP-View does not automatically delete log files, the Linux system admin may wish to schedule the above commands in a periodic CRON job to maintain optimal performance.

If server upgrade or restart issues continue to occur, please reach out to the Tech Support team.

Default Disk Encryption

As the NP-View OVF is typically installed within a secure environment, the disk is not encrypted by default for data at rest.  The Linux Admin can encrypt the system drive for increased security knowing that system performance will be slightly degraded to accommodate the data decryption and encryption.

Personalize the Login Page

To add a custom message to the login page, a NP-View administrator can edit the file /opt/np-live/docker-compose.yml with the following entry in the webserver environment section: “- banner=Welcome to NP-view”

For NP-View, the file ~/Documents/np-live/config.ini can be edited to add: “banner=Welcome to NP-View”

Upload File Size Limit

When users upload a file through the Web user interface, NP-View will enforce a maximum file size which is 200MB by default. To change it, a NP-View Linux administrator can edit the file /opt/np-live/docker-compose.yml with the following entry in the webserver environment section: “- MAX_IMPORT_SIZE=209715200”.  The value is in bytes, so 209715200 corresponds to 200MB.

Backing up the NP-View Server Database

1. Stop the NP-View Server (you can use the script /opt/np-live/stop_nplive.sh)
2. From the NP-View Server folder (by default: /opt/np-live/, run the command: tar -zcf db_backup_$(date '+%Y_%m_%d').tgz db (this command may take few minutes to complete)
3. Run the new release installer, which will update the containers and then launch NP-View Server

Complete Removal of NP-View

If you wish to completely remove NP-View from you server to start with a fresh install, perform the following steps:

• Stop NP-View using the script /opt/np-live/stop_NP-Live.sh
• Remove Docker containers using the command docker system prune -a as root (WARNING: this will completely reset Docker, so if non NP-View containers have been added they will be deleted as well)
• Remove the NP-View folder with the command rm -rf /opt/np-live as root (WARNING: the NP-View database will be permanently deleted)

‍

Network mapping provides the Networking Team (Network Engineer, Network Security) with capabilities that allow users to:

• Visualize an accurate topology of the network architecture
• Identify and label critical cyber assets and critical network zones
• Easily review which devices are protecting which network zones

Visualize Topology

NP-View can be used to discover your network topology and the underlying control plane, including layer-2 and layer-3 configurations. Without leaving the topology map, you can review many aspects of the network’s design including Firewalls, Routers, Switches, Gateways, Networks, VPNs, Hosts and more.

Critical Assets and Zones

Each asset can be tagged with categories and criticalities as well as grouped into zones making it easy to review which devices are protecting which network zones.

Details On-demand

Selecting a node in the topology map will interactively display an information panel with detailed data about that node.

Firewall ruleset review provides Network Engineers, Network Security, and Compliance Analysts with functionality for:

• Easy review of firewall access rules and object groups using the Access Rules and Object Groups reports.
• Automatic identification of configuration risks using the Risks and Warnings report.
• Validating recent policy modifications as part of a configuration change review process using the Change Tracking report.

How to Review Access Rules

An independent review of firewall policies has to be periodically conducted to ensure that network access rules are correctly implemented and documented. It is important because lack of access rule review leads to unexpected network access vulnerabilities.

• Frequency: each time firewall policies are changed, and at least once a quarter
• How to do it:
  • Step 1: given a workspace populated with network device configurations, open the Access Rule table from the main menu (top left)
  • Step 2: leverage the “Column Search” feature or the “Compare” feature to show the rules in scope of your verification
    • For instance, filter the “Device” column to only show rules for a specific device, or filter the “Binding (ACL)” column to only show rules bound to a specific interface, or use the “Compare” feature to only show rules added or removed recently
  • Step 3: review values for the source, destination, service, binding, risk, and description of each rule in scope
    • The “Description” column captures comment, description, or justification from the device configuration
    • The “Risk” and “Risk Criticality” columns are populated by NP-View during the automated risk analysis
  • Step 4: to identify rules that are not justified, sort the table by “Description”. Empty values will be shown at the bottom.
  • Step 5: to document your review process, double click on the “Comment” or “Comment Status” cells to add your own comment. The comment status can be either “Verified” or “To Review” or “To Revise”
  • Step 6: to save an evidence of your review process, export the table to Excel using the export options in the top right corner of the table

Access Rules Table

The Access Rules report provides the users with complete details on each Access Rule with the ability to add justifications and actions.

Object Groups

The Object Groups report provides the users with complete details on each Object Group with the ability to add justifications and actions.

Risks and Warnings

As modifications are made to the network, the Network Perception default Policies and Requirements identify potential risks.  The Risks and Warnings report provides the users with a summary of the potential risks and their criticality with the ability to add actions and comments.

Change Tracking

As modifications are made to the network and the updated configuration files are imported, the changes are logged in the Change Tracking table.

Segmentation verification provides the Networking Team and Audit Team with capabilities that allows users to:

• Assess correctness of network segmentation
• Identify risky network connectivity paths
• Understand exposure of vulnerable assets

Network Segmentation Accuracy

NP-View be used to verify the accuracy of your network segmentation.

The connectivity matrix which is available from the device info panel can be used to verify open ports between devices.

Inbound and outbound connections can be verified for each network using the highlight paths function.

Identifying Risky Connectivity Paths

Using industry best practices, Network Perception automatically identifies potential risks related to network configurations. Using the Network Perception  Connectivity Path analysis, the user can review each of the highlighted risks and make a judgment on action.

Exposure of Vulnerable Assets – Vulnerability Analytics

NP-View provides your security team with a single pane of glass for reviewing network vulnerability exposure. With the addition of scanner data or data from a vulnerability data service, vulnerabilities can be tracked across your network.

Topology Display of Vulnerabilities

When scanned data has been added to a workspace, and a topology view is built that also includes that scan data, nodes on the topology of that view will be marked with a shield indicating the presence of vulnerabilities.

These shields can be toggled on and off using the topology settings menu.

Device Panel Display of Vulnerabilities

Firewalls, Gateways, and Hosts may contain vulnerability and service information imported from scans. Clicking on any of these nodes in a View that contains vulnerability information, will display it in the info panel that opens over the main menu.

Clicking on the Vulnerabilities link will present a pop out with the vulnerability details.

‍

Performing a regular review of your compliance metrics is important for your organization.  Performing the review manually is time consuming and tedious. Audit assistance provides the Compliance Team (Auditor, Compliance Officer, Compliance Analyst, and Consultants) with capabilities that allow users to:

• Verify compliance with cybersecurity regulations and best practices through Policy Review.
• Seamlessly store evidence for compliance review with Change Tracking.
• Easily prepare compliance reports using the Audit Assistants listed below:

Workspace Report (Standard)

The Workspace Report assistant is available within each workspace and will generate a report for a specific view that includes detailed information about configuration files that were imported and parsed including:

• Configuration assessment report including risk alerts
• Ports and Interfaces
• Access rules
• Object groups
• Path analysis

Industry Best Practice (Premium)

The Best Practice assistant requires a license to activate. This report is available within each workspace to generate a report for a specific view that includes the following topics:

• Parser Warnings and potential misconfigurations
• Unused Object Groups
• Access Rules missing a justification
• Unnamed nodes
• NP Best Practice Policies on access rules and CiS Benchmarks that have identified potential risks
• ACL’s with no explicit deny by default rule

NERC CIP Compliance (Premium)

The NERC CIP assistant requires a license to activate this function and guides the user through the steps required to create a report covering CIP-005 requirements. The NERC CIP audit assistant is only available within a NERC-CIP workspace and allows audit teams to classify BES cyber assets as High, Medium, and Low based on the standards. We have added a category for untrusted (Internet, Corp, etc.) to tag non BES assets. NP-View allows compliance teams to collect and report evidence related to the following requirements:

• CIP-002 – BES Cyber System Categorization; impact rating and 15-month review
• CIP-003 – Security Management Control; cyber security policy
• CIP-005 – Electronic Security Perimeter; remote access management
• CIP-007 – System Security Management; ports and services
• CIP-010 – Change Management and Vulnerability; configuration change management, configuration monitoring, vulnerability assessment

A demo workspace for the NERC CIP audit assistant is included with the software.  To see the audit assistant in action, follow these steps:

1. Click on the demo workspace to build the topology.
2. Create a custom view by selecting all of the firewalls, right click, Create View from Selection and give it a name.
3. Once the view is generated, select Manage Zones from the left manu and click on the Auto Generate Zones button.
   • Red zones represent your high criticality assets.
   • Orange zones represent your medium criticality assets.
   • Yellow zones represent your low criticality assets.
   • Gray zones represent your untrusted assets.
4. On the left menu, select Summary Reports and the NERC-CIP Compliance Report
5. Click through the wizard, the defaults will represent the selections suggested by the auto group function.
6. Click Generate Report to view the report in a new tab.

Overview

In NP-View there are three levels of segmentation that can be used to organize your assets. From the most general to most specific these are:

1. Workspaces: Contain a group of devices
2. Views: Segments the devices present in a workspace into multiple views
3. Zones: Segments the devices present in a view into multiple visual zones

This article will focus on Views and the different functionality around them.

Home View

• After creating a workspace and uploading 1 or more configuration files, NP-View will automatically generate the Home View.
• The Home View presents a high level overview of the primary devices within the workspace (Firewalls, Routers, and Switches).  It is the starting point for all workspaces.
• To view assets connected to the primary devices as well as path analysis a new view must be created. (All views other than the home view will contain all the assets connected to the selected primary devices along with path analysis data.

Manage Views

Manage Views: All View related functions can be accessed from the main menu under Manage Views and can be opened from:

1. The main menu
2. With the shortcut key “V”
3. From the view navigation bar at the top of the map
4. Right click on a node or group and using the right-click menu

Creating a View

When opening Manage Views in a workspace that contains only the Home View, you cannot edit the Home View, so a new view will need to be created.

1. Open Manage Views
2. Select Create New View
3. Name the View
4. Choose the Devices and/or Auxiliary Data to include in the new view
5. Choose whether or not to include external paths (This can provide a more complete picture but significantly increases build time, and is not always necessary)
6. Create View
7. The view will be created in the background allowing continued use of the home view until the analysis has completed and the view has been built.
8. Once completed, the topology map will switch to the newly created view with the view details.

Note: Devices can be connected by a solid or dotted line. A solid line indicates evidence of a direct connection. A dotted path represents a connection that is inferred from the information provided (e.g., a layer 2 connection). Additional configuration data is required to convert inferred to direct connections.

Editing View

Existing views can be updated by opening Edit mode

• Select the desired View
• Click the kebab menu
• Select Edit

From this point you can

• Rename the view
• Add or Remove devices from the view
• Change Path Analysis used (will reprocess the view and topology)
• Delete the view – Select the Trashcan from the kebab menu (only the view will be removed, not data will be deleted)

View Navigation

Navigation between views can be accessed in 2 ways

1. From the topology: by opening the View Navigation dropdown
2. From Manage Views by opening the menu navigating to manage views and selecting a View.

New in 5.0 [Release Notes] we’ve included:

1. Now you can load and work with the details of a view without loading the view on the map
   1. Views are only loaded on the topology if the Play button is selected
   2. View details only are loaded if the row itself is clicked
2. Views build and rebuild in the background allowing you to continue work while a view is being generated

Limitations

Devices per view are limited by the product purchased as outlined below:

• Desktop: 15 devices per view
• Server : 25 devices per view

The above limitations also depend on the size and complexity of the configuration files and the specifications of the system.  Lower powered system may reduce the capability to support the above limits. YMMV.

Overview

In NP-View there are three levels of segmentation that can be used to organize your assets. From the most general to most specific these are:

1. Workspaces: Contain a group of devices
2. Views: Segments the devices present in a workspace into multiple views
3. Zones: Segments the devices present in a view into multiple visual zones

This article will focus on Zones and the different functionality around them.

Zones – Defined

Zones in NP-View are the most granular form of segmentation that is offered. Zones are visual markers that group nodes together. They can be created by user’s on demand, or through the Auto Generate Zones function in Manage Zones, on the main menu. Zones can be named and assigned a criticality.

Below is an example of a Zone with a High Criticality, named EMS-Backup.

Adding Zones

Adding, Editing, and Deleting Zones can be done

1. Manually – From the Topology
2. Automatically – From the Main Menu >> Manage Zones

Manually – The Topology

1. Hold Shift
2. Select a group of nodes
3. The Multi-Selection panel will open over the main menu
4. In the middle of the panel there is a Save Selection as Zone segment
5. Give the grouping a name and criticality
6. Create Zone
7. The Zone will appear on the Topology

Automatically – Manage Zones

From the Main Menu Manage Zones can be accessed. This is the primary place to work with Zones in NP-View. From Manage Zones you can Autogenerate Zones based on keywords found in the section below.

Manage Zones from menu

Auto generate zones only available if no zones have been created.

Zones will be automatically named and color coded based on asset keywords.

Once Zones have been generated they will appear on the map and each zone will be listed in manage zones. Clicking any zone, either on the Topology or from Manage Zones will open the details for the Zone

Edit/ Delete Zones

Once created, zones can be manually reclassified or deleted by clicking inside the zone space and selecting the appropriate option from the menu. If some devices are not properly included in a zone, the devices can be selected and manually (or right clicked on and added to a zone).

Once automatic zones are created, the Auto Generate Zones function is disabled until all zones are deleted.

For manual zone creation, the user can select two or more objects from the topology map and the zone panel will display.

From the panel, the user can create a zone, name it and assign a criticality. The user can also assign tags and criticalities to the selected devices.

For existing zones, the user can add / remove nodes from zones, edit the name or criticality or delete the selected zones.

Selecting a zone name displays the details for the zone. The user can rename the zone or reassign the criticality.  They can also perform a zone analysis of inbound and outbound paths.

Right clicking on any topology object will allow for the addition or removal of an object from a zone.

‍

When was it introduced?

• Beginning with NP-View Version 5.0 (release notes) users will now have access to a new feature called the NAT Rules Report.

What does it do?

• Displays all information available for NAT Rules on the selected Device.

Where is the Routes Report located?

Available from a selected Firewall’s Information Panel

‍

Network visualization is the most powerful feature of NP-View.  Create a workspace, import configuration files and supporting meta data, and NP-View’s visualization function will process the information into a usable network diagram.

Home View

The Home View shows the user a high level overview of the primary devices within a workspace (Firewalls, Routers and Switches).

The home view is the starting point for all workspaces. Devices can be connected by a solid or dotted line. A solid line indicates evidence of a direct connection.

From the home view, the user can:

1. Select a single device (left click) to view details on the information panel.
2. Select multiple devices and create zones. See more info on zone creation.
3. Select one or more devices and create a view. See more info on view creation.

When objects are moved on the topology map, the ‘Save Topology’ button will become active.  Multiple objects can be moved prior to saving the topology.

If the user attempts to switch views before saving, a notification will be presented as follows:

The user can either cancel the operation and then select ‘Save Topology’ or proceed to the selected view without saving.  Selecting OK can also be used as an undo function.

Topology Network Map

From the topology view, the user can rearrange the objects on the canvas by selecting and dragging a device to a new location. Device location can be saved with the “Save Topology” button.

Devices can be assigned a category (colored text tag) and criticality (colored ring).

If a device has active alerts, the number of alerts is displayed in the top-right corner (red circle).

If a device has user entered comments pertaining to this device, the number of comments is displayed in the top-left corner (blue circle).

Multiple devices can be selected by holding the shift key down (the cursor changes to a + sign) and dragging the mouse to make the selection.  The Ctrl key can be used to select / deselect individual devices. Once selected, the devices can be assigned to a common category or criticality.  Alternatively, the devices can be assigned to a of zone. See more info on zone creation.

Unmapped hosts and networks indicate IP addresses that are external to the topology and could not be connected to primary networks. For a given networking device (e.g., a firewall), primary networks constitute the IP ranges defined by its interfaces. In other words, all the networks a device faces are called primary. Nonetheless, the device’s ruleset can refer to arbitrary IP spaces, not necessarily those within primary ranges. Consequently, NP-View identifies those external/unknown IP spaces as hosts, networks, or ranges, as defined in the config, and places them behind the Unmapped gateway.

Additional topology features include expand / collapse a node, auto arrange peers in a circle and pin / unpin a specific node. These features are available when clicking on a node and using the kebab menu on the info panel.

Tip: When importing a devices, the topology map attempts to place each node in an unused slot but may overlap nodes and paths.  By selecting unpin, moving one device, selecting center and then pin, the map will auto arrange.  For topologies with over 100 nodes, the hosts will automatically be collapsed to make the map easier to read. Each collapsed network can be individually expanded or the entire map can be expanded but for very large workspaces, this may take some time to expand.

Firewall Device Information

For Firewalls, Routers and Switches, when selecting a device, the device attributes will be displayed on the left device information menu.

The device panel will be displayed with the appropriate label. The device type is defined by heuristics.  If the device is misclassified, clicking on the drop down allows the user to reclassify the device as a firewall, router or switch.

The user can also assign a category and a device criticality. Additional information includes being able to review multiple version of configuration files and compare them with the diff viewer. Configuration files must have the same name for the diff viewer to identify and compare files.

A risk assessment grade is assigned for each firewall based on the number of open risks and warnings and their associated criticality.

The connectivity matrix shows all of the connections for the selected firewall and the IP rules for each connection. This is only available from within a custom view.

Risks and Warnings shows the active risks, warnings and the criticality for the selected device.

Access Rules shows the rules for the selected device with the ability to compare two sets of rules and display the differences.

Object groups shows the object groups for the selected device.

A summary of the number of routes and a table of the interfaces are also displayed.

Administrators and Workspace Admin’s can delete devices from the workspace using the delete option under the tree dot menu.

Host Information

For hosts, the following is displayed:

‍

Users can assign a host icon, category and a criticality.

Display inbound / outbound connectivity paths as well as displaying stepping stone analysis.  Inbound and outbound connections are filtered to show the exact match for a given path. In some cases, no inbound or outbound paths will be displayed. (See below)

Display the services loaded from PCAP files.

Display vulnerabilities loaded from Vulnerability Scanner files.

Custom Views

Custom views are used to organize devices and analyze the paths between the devices. Path analysis and stepping stone analysis is only available from within a custom view. Additional information on custom view creation can be found here.

Network & Gateway Information

For networks and gateways, the panel to the left will be displayed.

‍

Users can assign a category and a criticality.

Additional information includes being able to review the IP address of the connected hosts.

The user can also search the config file for the device.

Display inbound connectivity / outbound paths as well as displaying stepping stone analysis. When selecting Inbound or Outbound, all paths are highlighted in gray, selecting a specific protocol will highlight the path in orange.

Connectivity Paths

When displaying the device menu for a specific device, clicking on the arrow (>) will expand the inbound and outbound connections.  Clicking on any service or IP will highlight the path on the topology map.  Source objects are designated by blue circles (Src) and destination objects are highlighted by red circles (Dest).

Additional path information is shown including the rule associated with the path.  Clicking on the blue text will invoke the access rules with the associated information.  The user can also add a comment if required.
‍

Stepping Stone Analysis

‍

Stepping Stone Analysis is available on custom views for Networks and Endpoints. Click any node that is not a Firewall/ Router/ Switch and open the info panel.

Find the Accordion section named "Stepping Stone Analysis" and open to reveal options.

Run as Source or Run as Destination.

‍

‍

‍

‍

‍

The colors reflect how many hops a way another node is from communicating with the analyzed node. The pie slices on the analyzed node show the distribution of nodes per number of hops.

Path Block Analysis – Troubleshooting Path Blocking Issues

‍

The above sections describe the different types of Path Analysis available in NP-View that will give information about connections in the Topology. But what if we want to confirm that a connection is blocked? For this NP-View offers Path Block Analysis.

Path Block Analysis allows a user to take two hosts/ two networks/ or one host and one network and to troubleshoot if the connection between is blocked, and if so why.

Open a Topology View that is not the Home View and select two nodes you wish to Troubleshoot Path Blocks on. When the two nodes are selected, right click on one of them and select “Troubleshoot Path Blocking Issue”

‍

‍

A dialog will slide out of the right side of the screen. The Source and Destination of the selected nodes will be entered and can be swapped. Protocol and Port are pre-populated and cannot be changed. Path Block analysis always searches using IP/any. Clicking Start will begin the analysis.

Path Block Found

When a Path Block is found the dialog will have a red notification, and the Blocked Paths window on the left side of the screen will be populated with the block information, including the reason why traffic is blocked. This information is not stored and will be erased as soon as ESC is pressed.

Path Block Not Found

When a Path Block is not found the dialog will present a green notification. The Blocked Paths window on the left side of the screen will be populated with a message that no blocks were found.

‍

The following table is a comprehensive list of supported devices. The instructions provided in the table can be used to manually extract data from the device for import. While we do our best to support the below devices, it is impossible for us to test the parsers with every possible device configuration combination. If errors occur during device import, Network Perception is committed to working with our customers to resolve their specific parsing issues.

Note that Network Perceptions device support policy follows that of the manufacturer.  When a manufacturer ends support for a product, so does Network Perception.  End of support devices are not removed from NP-View but will not be upgraded if issues arise.

Supported Devices with Vendor Partnership

The devices in this list are actively tested in our lab to support the most current versions of the manufacturer software. Network Perception has an active partnership with these vendors for software and support.

Supported Devices with no Vendor Partnership

The devices in this list are actively tested in our lab to support the most current versions of the manufacturer software.

Historical Devices

The devices in this list were developed based on customer provided configuration files.  We are no longer actively developing these parsers but they are supported for break/fix and require customers sanitized config files to assist with the debug of issues.

Additional Instructions

Palo Alto Panorama & NGFW

+

Panorama

If Panorama is used to centrally manage policies, the access rules and object groups can be retrieved from these devices in XML format (we do not support the import of unstructured text files). If using the Panorama connector, the required files will automatically be downloaded:through 6.2 ended September 2023. Please note that no upgrades to these parsers will be made.

The Panorama file will only contain centrally managed access rules and object groups.

Locally defined access rules and object groups cannot be retrieved from Panorama and must be retrieved from each NGFW. Please follow the instructions below to export directly from the Next Gen FireWall using API.

Palo Alto Firewalls will ALWAYS have a V-sys even if one has not been configured it will default to vsys1.

The “mapping_config” file is required which can only be retrieved through the API using the “show devices connected” command.  The name of the file is “named_mapping_config.xml” where the named prefix needs to match the device name as shown in the UI when the running_config.xml is imported alone. All files should be imported at the same time. Please see instructions below:

The below links are to the Panorama documentation for the required commands with examples. The links provide you with commands to run directly in the Panorama CLI. The images we provided are for using Postman or web browser use.

Get API Key

Get Panorama and device bundle Configuration

Get device mapping config

Once both the “<panorama_server>_running_config.xml” and <panorama_server >_mapping_config.xml” are gathered, please import them together in NP-View.

Next Gen Firewall (NGFW)

If using the PanOS connector is used to download files, the required files will automatically be downloaded:

The configuration information from the NGFW may be contained in several .xml files, <device-name>_merged_config.xml and <device-name>.vsys(n)_pushed_policy.xml.  There can be one vsys file per virtual interface. The naming of these files is important for the parser to merge them during import.  All files from a single firewall must be imported at the same time and in .xml format (we do not support the import of unstructured text files).  If any of the files are missing, improperly named or formatted, an error message will state that ‘File parsed but ruleset and topology were empty, aborting’ meaning they could not be linked to the other associated files.

An example of properly named files is below:

• Chicago-IL-100-FW1_merged_config.xml
• Chicago-IL-100-FW1.vsys1_pushed_policy.xml
• Chicago-IL-100-FW1.vsys2_pushed_policy.xml

NOTE: If the NGFW is an unmanaged/standalone Palo Alto device it will not have a pushed_policy file. In this situation, the configuration .xml file can be downloaded directly from the firewall and loaded into NP-View.  The file name need not be changed when loading the file from a standalone firewall.

To manually export configuration files from an unmanaged firewall:

If the NGFW is managed by a Panorama, the API will be required to secure the necessary files:

Get API Key

Get PANos Firewall full configuration

Get Managed Firewall configuration

Virtual Routers (vrf) – Experimental Support

Virtual router (vrf) is a software-based routing framework in Palo Alto NGFW that allows the host machine to perform as a typical hardware router over a local area network. NP-View has added the experimental capability to detect Virtual Routers from Palo Alto devices (NGFW or Panorama) and present them in the Connector or Manual Import device selection screens. Virtual Routers will be treated the same as physical routers and will require a device license.

This feature is disabled by default and must be enabled prior to importing configurations containing virtual routers.

To enable the feature the NP-View Server admin will need to make a change to a system variable.

• Stop the NP-View Server application.
• in the docker-compose.yml file, change the enableVirtualRouters=False to enableVirtualRouters=True in three places within the file.
• start the NP-View Server application.

For Desktop

• Close the NP-View application.
• In the file C:\Users\<username >\AppData\Roaming\NP-View\config.ini add enableVirtualRouters=True
• Restart the NP-View application

Once enabled, the user will be presented with the option to select virtual routers from the connector in the device selection or upon manual import.

SonicWall

+

We support .exp files as the default SonicWall file format for v5.9 and v6.X of the SonicOS.

The main UI allows for export of the encoded .exp file as such:

To extract the file via command line, then the command to export is

export current-config sonicos ftp ftp://[USERNAME]:[PASSWORD]@[FTP IP/URL]/sonicwall.exp

Where the username/password/FTP IP or URL must be changed. The file “sonicwall.exp” will then be saved at the FTP location. As this file is encoded, there’s no way to echo or cat the data.

Requesting Support for New Devices

The above list of supported hardware has been lab and field tested.  Newer versions generally work unless their is a major platform or API upgrade.  Please contact support@network-perception.com if you wish to get more information on parsers, request support for a particular device or are interested on co-developing a solution.

NP-View includes a utility to automatically retrieve network device configuration files on a schedule. The connector types supported in NP-View Server are below:

Configuration Managers

For retrieving config files from network management systems. For each connector, the user can select the devices to be uploaded for monitoring.

Direct Device Connection

For retrieving config files directly from the network device.

Volume Shares

For retrieving config files that are uploaded to a common collection repository.

‍

Additional Connector Information‍

Checkpoint

+

For the connector to work CheckPoint devices, the API setting need to be enabled in the SmartConsole.  See the image below for settings and commands to restart the API.

Samba

+

Network Perception suggests the following when setting up the SMB connection.

1. Create a read-only user in Active Directory or on the SMB server.
2. Determine the available share (Get-SMBShare” in Windows PowerShell) or create a new one.
3. Share the SMB folder containing the Configuration files with the read-only user. For example:

Configuration:

Lets assume that the server is at \\192.168.140.14\

• the shared folder is named 'share'
• and the files are in a sub folder of share called \test\NERC-CIP-EMS
• a UNC would look like this: \\192.168.140.14\share\test\NERC-CIP-EMS
• Per the above, the device name was set to LAB-SMB

When configuring the SMB connector, the screen would look like this:

If during the connector test, access is denied, the following settings should be verified and may need to be changed for the SMB to work as expected.

Running PowerShell as administrator

Input command Get-SmbServerConfiguration

Verify that EncryptData is set to false

If set to true, run command “Set-SmbServerConfiguration -EncryptData 0”

Verify SmbServerHardeningLevel is set to 0

If not set to 0, run command “Set-SmbServerConfiguration -SmbServerNameHardeningLevel 0”

Microsoft recommended default is off (0). More information about these settings can be found on the Microsoft website.

‍

If you have a system for which you need a connector or if you encounter a technical issue, please contact support@network-perception.com.

This document relates to NP-View Desktop and Server version 6.0 and later.

Connectors automate the secure retrieval of configuration files from firewalls, routers, switches, and network device configuration managers. NP-View Desktop and Server can host one or more connectors that securely retrieves configuration files manually (desktop and server) or at the specified frequency (server only).

To access the connector function, use the system menu in the upper right corner of NP-View and select 'Manage connectors'

‍

The connector function consists of several key features.

• Password manager to reuse and manage passwords across multiple connectors.
• Workflow for creating groups and connectors.
• Automated data collection and download.
• Flexible scheduling (Server only).
• Runtime and scheduling status (Server Only).

The connector function supports the files devices listed on the connectors page.

Add Credentials

To get started, the user must first create one or more credentials. Credentials are used to access the devices and can be used for one or more devices. This provides for the ability to manage multiple devices with one set of credentials. Click the 'Add New Credential button to display the input section. Credentials are segregated by device type. Select the device type and input the required fields.

Once filled in, select the save button and the credential will be saved and displayed in the 'Credentials' box. Clicking on the credential will allow the user to edit the credential.

At this time, Deleting a credential is not supported.

Create Groups

Once credentials have been created, the user can proceed to creating a Connector Group.

Select the '+' in the 'Groups' section to display the add groups function. Fill in the group name, notes and select a schedule (server only). For desktop, only the 'On Demand' function will be displayed.

Once saved, the user can click on the connector group name in the 'Groups' panel to enter edit mode or select the three dots to the right of the name for individual group options.

Pull to run all associated connectors and delete to remove the group. Note that only empty group can be deleted.

Scheduling Groups

Groups can retrieve data on a schedule, when setting up or editing a connector group, the user can set a schedule.

The user has multiple options for scheduling the connector; monthly, weekly, and daily with flexible day of week and time options. We recommend that connectors be run at night to provide maximum resources for processing the data. When a connector group is scheduled, the next run status will be presented in the 'Groups' panel

and on the 'Processes' tab

‍

Add Connectors

Once a group has been created, the user can add connectors to the group. In the connectors section, select the '+' to present the add connector function.

Proceed to select the connector type and fill in the required fields.

Next fill in the optional fields.

Filling in the name of a context will only fetch the data for that one context, leaving blank will fetch all contexts.

Selecting one ore more worspaces to deliver the fetched data. If left blank, the data will be retrieved for manual download.

The user can then test the connector to verify the credentials and/or save the connector.

Once saved, the user can click on the connector name in the 'Connectors' panel to invoke edit mode. Clicking on the tree dots next to the connector name provides individual connector options.

‍

Manual Data Pull

Data from individual connectors can be retrieved manually by selecting the 'pull' option from the menu above. When selecting pull, the connector status will proceed to 'in progress'

and the processes tab will also display the progress status.

Once data has been pulled, the user can selectively download the most current data set from the connector panel.

‍

‍

Deleting Workspaces

If a connector is designated to deliver data to workspace and a user deletes the workspace, the connector will automatically be updated to reflect the workspace deletion.

‍

In version 6.0, a new connector function was introduced. for new connector users, it is recommended to use the new connector function. The connector access has been moved from the +Import function to the system menu.

Connectors automate the secure retrieval of configuration files from firewalls, routers, switches, and network device configuration managers. NP-View Server can host one or more connectors that securely retrieves configuration files at the specified frequency. By default, connectors are accessible through HTTPS on port TCP/8443 of the NP-View server and is isolated for security purposes.

The first time an administrator accesses the connectors, they are required to define a Connector group name and a secure passphrase. The Connector group name will be used to create the encrypted connector file store. Connector information is encrypted at rest and in transit using a passphrase protected PGP key. Only the connector owners know the passphrase and the passphrase is never stored. Once initiated, connectors run in the background collecting network information.  If the NP-View server is restarted, the connector owner is required to re-authenticate and restart the connectors. Connector owners can create multiple connector groups and each will require their own login. Once created, the user can select from the list of available connectors when logging in.

The connector page contains five main options.

The buttons from left to right are:

• + Add New Connector
• bulk start all connectors (see bulk start parameters below)
• bulk stop all connectors
• delete the connector (user must be logged into the connector group to delete)
• exit the connector group.

Add Connector

To add a new connector, select “+Add New Connector”  button and a list of available connectors is presented. Connector options are: Cloud Providers, Configuration Managers,  Direct Devices and Volume Shares

Upon selecting the Connector type to add, the user is requested to fill in connection information. Connector information varies by vendor.  The connector configuration for a Palo Alto device is as follows:

The user must enter a Connector name (no spaces), host name, and credentials.  The user can then verify the credentials are correct with the “Test credentials” button.  The user can setup the polling cycle and provide the workspaces to deliver the resultant information.

Polling Cycles are:

• On demand
• Daily
• Weekly
• Bi-Weekly
• Monthly

Configuration Management Systems

For Configuration Management Systems and file Shares, additional information may be required.  The user can retrieve a list of files from the device and filter the results.  To include specific files, put them in the include list field.  To exclude files, put them in the exclude list field.  If both lists are used, include list filter will be applied first and the exclude list filter to the results of the include list filter. If the share is PGP encrypted, a PGP Public key will be required.

Workspaces must be added to the connector for data to be transferred and displayed in the workspace.  If workspaces are added after a connector is setup, data will not be sent to the workspace until the next scheduled import and a configuration change is identified.  Creating workspaces before connectors facilitates faster visualization of data.

Connector Tile

Once the connector is added, a tile is added to the connectors home page.

Connector tiles are sorted by the characters in their names using standard Linux conventions:

1. whitespace
2. integer
3. special char
4. uppercase [A-Z]
5. underscore (possibly other special chars)
6. lowercase [a-z]

From the tile, the user can:

• manually activate the connector for a one time data pull
• run / pause the connector
• edit the connector
• copy the connector
• delete the connector.

The tile banner will show in three colors:

• red – connector failed
• blue – connector scheduled to run
• gray – connector paused

Click the start / pause button to restart a failed or paused connector, note that a connector may take several minutes to change the banner color.

Connectors + Samba (SMB) Access Error

+

This error can be caused by two communication scenarios between Linux and Window. Either SMB encryption is enabled on the Server or SPN target name validation level is enabled (or both). To check which of these features is causing the issue, Run PowerShell on the Windows Server as administrator and run the following command:

Get-SmbServerConfiguration

If EncryptData = True, it can be disabled using:

Set-SmbServerConfiguration -EncryptData 0

If SmbServerNameHardeningLevel is set to any value other than the default of 0 run:

Set-SmbServerConfiguration -SmbServerNameHardeningLevel 0

to restore the default.

The linked .html file runs a self contained config file sanitizer in a standard web browser. The configuration sanitizer will change IP addresses within the file to mask them. This sanitizer will maintain integrity across the masked IP addresses so that we can properly test the file in the test lab. Please do not manually change the file after running through the sanitizer. To use the sanitizer file, click the link below to run in your browser.

Run from here

Below are the currently known issues in NP-View along with the available workarounds. These issues will be addressed as part of the upcoming release. If you are experiencing an issue not covered in this document, please contact Technical Support at: support@network-perception.com.

1. Typing into a field in NP-View Desktop doesn’t register any text

Reset window focus (This may not always work)

• Alt+Tab out of the application
• Alt+Tab back into the application

Login to NP-View Desktop via web browser

• Open a web browser (Chrome/Edge) with NP-View still running
• Type “localhost:8080” in the address bar to load NP-View in a browser window

NP-View is licensed on an annual basis. The cost of the license depends on the number of configuration files imported from primary network devices (firewalls, routers, and switches).

How Licensing Works

When importing devices (manual or automated), a reminder notice is provided stating: “Importing new devices requires available licenses. Devices are activated in the order they are imported. If the total license count is exceeded, importing of additional unlicensed devices will be prohibited.

To determine the available number of devices licenses, see the summary at the bottom of Licenses and Terms.

Supported Devices and Connectors

The knowledge base contains a list of actively supported devices (link) and connectors (link). These lists change over time as manufacturer end of life support and as we add support for new devices. These lists are referred to in our terms of service and used to define what is in scope of the NP-View license agreement.    Network Perception reserves the right to alter this list at any time without customer notice.

‍

When Device Licenses are Activated

Device licenses are activated when a device is first imported.  When the device limit is reached, import of additional devices (manual or automated) will be prohibited and a message will be issued in the help center and system logs.

Device licensing is permanent.  Once a license is allocated to a device it cannot be re-assigned to another device.

Palo Alto NGFW and Virtual Systems (VSYS)

Virtual systems are separate, logical firewall instances within a single physical Palo Alto Networks firewall. Rather than using multiple physical firewalls, IT departments can use a single firewall and enable virtual systems on them to independently separate traffic.

The default is vsys1. You cannot delete vsys1 because it is relevant to the internal hierarchy on the firewall; vsys1 appears even on firewall models that don’t support multiple virtual systems.

When using multiple virtual systems, if a configured vsys has an interface with access rules, NP-View will represent the vsys as a separate firewall and a device license is allocated. If a vsys has no interfaces or access rules and is used only for object management then NP-View does not display the firewall and it requires no license.

FortiGate and Virtual Domains (VDOM)

Virtual Domains (VDOMs) are used to divide a FortiGate into two or more virtual units that function independently. VDOMs can provide separate security policies and, in NAT mode, completely separate configurations for routing and VPN services for each connected network. If a VDOM has no interfaces or access rules and is used only for object management then NP-View does not display the firewall and it requires no license.

Hiding Devices

If a device is no longer required in any workspace, the Administrator can hide the device from all workspaces by unchecking the “Visible in Workspace” check box and selecting the “Submit” button.

The licensed device will remain in “license and Terms” and displayed as follows:

The data is not deleted from the workspaces. If the Administrator wishes to restore the device to all workspaces, they can by importing new data for the device or by rechecking the checkbox and clicking “Submit”.

Note: NP provided demo devices in the demo workspace are excluded from display in the license manager and device counts.

User Deleted Devices

If the user deletes a device from all workspaces, the device still remains licensed but as it has no system association will not be displayed in License and Terms.  The device can be restored in the future by importing new data for the device into any workspace.

Expired Licenses

When the license expires, workspaces for all users will be disabled along with manual data imports. A message will be displayed stating that the license has expired and to contact sales to renew. Connectors will continue to collect data and deliver the updates to workspaces and demo workspaces will continue to function.

License Downgrade

If a customer downgrades their device count, the Administrator will need to select the devices to remain active after inputting the new license key. If the Administrator does not select the devices to remain, the system will allocate the devices in the order they are used. All remaining unlicensed devices will be removed from all workspaces.

Compliance Module Downgrade

If a customer downgrades their compliance module license, all workspaces associated with that module will be disabled. The user can manually delete these workspaces.

Existing Customer Upgrades

For existing customers upgrading from a previous version of software to version 3.1.0 or later, devices that are imported and active in the license manager (check box marked) will remain licensed.  Devices that are unlicensed (check box unmarked) will be removed from all existing workspaces. If a customer needs to replace one or more devices, please contact support.

Auditors and NP Certification

Auditors and NP Certification members working project style engagements using NP-View Desktop are provided with a special feature to reset the system to its original state after an engagement so that no customer data is retained.

Adding a license to NP-View Desktop and NP-View Server

• Step 1: Create an account on the Portal website
• Step 2: If you don’t see an active license in the Portal home page, select “Request License” or contact support@network-perception.com
• Step 3: Once a license key has been generated for you, make sure the format is correct. It should be a JSON structure similar to:

{
"email": "email address",
"type": "License type",
"expiration": "date",
"max_rulesets": "purchased device",
"max_users": "purchased user",
"module_np": if purchased,
"module_nerccip": if purchased,
"key": "secret key"
}


• Step 4a: For New Installations, upon system installation, the Administrator will input the NP license key into the setup screen which will set the maximum limit on the number of devices that can be imported (manually or automated) into the system.
• Step 4b: For existing customers, launch NP-View and select “License & terms” from the user menu (top right corner).

• Then scroll down and select “Upgrade or renew your license” followed by “Input license manually”. You can then copy/paste the license JSON structure (including opening and closing curly brackets) into the text field area.

• Note: the licensing function is available only to the Administrator role in NP-View Server and the must logout and re-login for the license to take affect.

HA Device Licensing

NP-View Professional server support the licensing of active / passive high availability (HA) groups for firewalls. HA Group definitions are only required if the device name of the primary and secondary devices are different. Once the active firewalls are loaded into NP-View, the HA definition file can be exported using postman or a tool of your choice using:

GET /license/ha-groups?file-export=true and a file will be downloaded.

The file export will be a text file. Column 1 will be the HA Group name and will be initially empty. Column 2 will be the firewall name.

HA Group Name, Device Name
, asaDMZ-fw1
, asaUCCtoBA1
, asaUCCtoSub-A
, asaBA
, firewallSub

The administrator will then update the text file to add unique group names as well as the name of the passive firewall. The updated file can look as follows. Devices without group names will remain as individual firewalls.

HA Group Name, Device Name
A-Group, asaDMZ-fw1
A-Group, asaDMZ-fw2
B-Group, asaUCCtoBA1
B-Group, asaUCCtoBA2
C-Group, asaUCCtoSub-A
C-Group, asaUCCtoSub-B
, asaBA
, firewallSub

Once the file is updated, the file can be posted using postman or the tool of your choice:

POST /license/ha-groups

When new firewalls are added or groups need to be redefined, the above GET / POST process can be repeated.

HA Groups will share one device license. If firewalls are ungrouped and there are not enough free device licenses, the user will be asked to remove firewalls from NP-View that are to be unlicensed and deleted from the system.

NP-View has a series of shortcut keys to quickly access commonly used functions.  This section describes some of the frequently used shortcut keys. Note the the list of shortcut keys is available from the upper right menu or by using the “K” key
