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.

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.

NP-View provides a simple and easy way for users to add comments and other metadata to rows in Access Rules, and to track the historical lineage of these comments in a workspace. Comments can be added, or viewed, for integrity purposes they cannot be edited or deleted.

Adding a Comment: Comments can be added to a row by double-clicking on the cell in the column “Comment”.  Comment text and status can be added and then saved with the save button. Once the comment is saved, the author and time stamp are automatically inserted.

*applying comment

*applying comment – closeup

Comment History: Additional comments can be added to a row to begin creating a lineage or history of comments. This history will be automatically available when more than one comment exists on a row and can be expanded by clicking the blue clock icon on the leftmost column of the table. If there is no history the icon will be disabled.

When viewing history, changes between lines are highlighted in blue.

Example: If Comment 1 is: “rule comment 1” – ‘verified’ and Comment 2 is “rule comment 1a” – ‘to revise’ the status cell would be highlighted because there was a change – the comment text would not be highlighted if the text remained the same.

*Viewing comment history

Access Rules Hash

Access Rules are uniquely tagged (Object ID) within NP-View for linkage to comments and risks.

Additional Features

• The Compare button invokes a time series comparison function for the report.   Additional details on this function can be found here.
• Comments can be imported from an Excel file.  Additional details on this function can be found here.
• Conditional formatting can be applied to this table report.  Additional details on this function can be found here.

Comparison Report

+

Access Rules and Object Groups have a Compare function to show historical differences in data that has been added or removed. The function can be engaged by clicking the “Compare” button located at the top of the page. This function is used to display changes over a period of days.

The user can select a time frame (7, 30, 90 or 356 days or a custom date range). The user can select one or more devices to include in the report and then show the history over the range. Once the parameters are selected, the “Show Comparison” button should be selected.

The comparison function will display all changes (Rule Adds, Rule Removal and Unchanged Rules) for the selected days. The data will be displayed using the column format of the selected table. The user can filter on added, removed or unchanged rules by clicking the jelly bean. Added rules will be highlighted in green, removed rules will be highlighted in red and unchanged rules will be highlighted in light blue.

Clicking the “Compare” button will revert to the normal table but will not clear the selections.

Clicking the “Reset” button will clear the selections and reset the table.

This article will focus on the Asset Inventory Report.

NP-View uses reports to present network information related to the open workspace.  These reports are available to all users and can be accessed from the main menu. For more information visit the Workspace Reports Overview article.

Asset Inventory

This report provides a summary of all assets loaded into the workspace including: Firewalls, Routers, Switches, Gateways and Hosts.

Unmapped – What is it?

For some devices there may be a large number of hosts defined in the Asset Inventory but less shown on the Topology Map. These “missing hosts” are not actually missing on the map, they are hidden in a Gateway node titled ‘Unmapped’.

If an IP address is displayed as 0.0.0.0 this device has an IP address assigned by DHCP and while the device was detected, an IP address could not be extracted, and it would be said to be an Unmapped Host. Unmapped hosts have enough information for identification but not for mapping purposes on the topology map.  These ‘invisible’ hosts are located behind the Unmapped, or other, gateways and can be seen in a given gateway’s peer list.

‍

NP-View uses reports to present network information related to the open workspace.  These reports are available to all users and can be accessed from the main menu.

This article is focused on the Background Tasks Table.

Background Tasks

This table displays the active and completed processes both for the current workspace, and for all workspaces. When in a workspace you have the ability to filter and view the active processes for the current workspace and to clear or cancel completed or active processes for the current workspace.

Access: Background Tasks can be accessed in three ways.

1. From the main menu
2. Using the hotkey ‘T’
3. Clicking on the active spinner on the topology map

*main menu

     *active background tasks spinner

Overview

The Background Tasks table shows the status of each task spawned by a data import, merge, analysis, or by run policies.

• Parsing tasks indicate the imported file is being normalized and hosts inferred.
• Merge tasks combine the normalized data into the topology map.
• Analysis tasks define all of the paths and open ports.
• Policies review the active requirements to identify potential risks for review.

An example of the background tasks table is in the image below.

The report contains the following data and has the following functionality:

Report Data:

• Task name
• Progress
• Workspace where the task is running
• User who owns the task
• The time it started or ended

Report Functions:

• The check box allows the user to filter on the tasks pertinent to the current workspace.
• The X allows the user to cancel a task that may be running too long or be stuck for some reason.
• The user can also cancel all tasks within a workspace using the “Cancel All for this Workspace” button

Change Tracking

Overview

• The Change Tracking Report logs modifications that are made to the network and the updated configuration files that are imported.
• It can be accessed from the main menu
• For every change, the timestamp, action, device, and description are recorded.
• Changes are displayed and can be filtered by calendar day.
• At the top of the table is a drop down that allows the user to select which day to review.
  • The default is the current day.

Functionality

The Change Tracking Report can be:

• searched
• sorted by any column
• switched to a list view
• exported
• and configured with alternate columns if required

These functions are available in the upper right corner of the table.

Change Types

The types of change actions that are logged are:

1. File import – for each file uploaded, of the following statuses will be displayed:
   • “successful import” – file imported successfully”
   • ignored file: <filename> – unknown file type, ignored
   • “failed import” – file failed to import, review help center for reason
2. Topology map – for each file uploaded, of the following statuses will be displayed for the topology map
   • “device path information” – triggered if the connectivity matrix changes
     • Paths can be added or removed
     • Assets refers to destination IP addresses
     • Services refers to the unique ports (or any) associated with the imported device
     • Details on the above can be viewed in the Connectivity paths
   • “topology updated” – indicates the topology map has been successfully updated
   • “topology failure” – indicates the topology map has failed, review help center for reason
3. Connectivity Paths – for each file uploaded, of the following statuses will be displayed for the workspace
   • “workspace analysis updated” – all other tables have been successfully updated

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.

Asset Managers

For retrieving asset related information from asset management systems.

Experimental Connectors

Support for the following device connectors are in various stages of development and are provided for field testing purposes.  Using these device connectors may or may not work for your specific environment or configurations.  If you find issues with these devices, please provide your feedback to support@network-perception.com

Cloud Providers

For retrieving VLAN and services configurations from cloud providers.

Configuration Managers

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

Legacy Configuration Managers

These devices are no longer supported by NP-View.  While the system did support these devices in the past, the vendor no longer provides support to external developers and these devices have been removed from active support.

Additional Connector Instructions

‍‍

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:

1. If using the date folder and recursive search feature, clicking “See Current Date Folder” will retrieve most recent folder, in YYYYMMDD format, in the “Current Root Folder” f field. For example:

Optional fields:

1. Path to Root Folder – Directory you want to be the root folder relative to your default SMB root folder.
2. Recursive Search – Whether or not to search recursively starting at the connector’s root folder.
3. Name Filter – Filters file/directory names based on given regex statements. Any file/directory that fully matches ANY given regex statement will be included in result.
4. File Decryption Key – a PGP key can also be provided if the files retrieved have been encrypted.

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.

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 (+Import Data -> New connector -> Manage 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.

NP-View can import auxiliary data from third party systems to enrich and augment the analysis.  The data files listed below are supported and can be manually imported using drag and drop or through a shared network drive connector. We recommend importing configuration files first or at the same time as the auxiliary data files or a system error may occur. If auxiliary data is input after configuration files are processed, the auxiliary data will need to be added to a new or existing custom view(s) to display the data.

Hosts

Hosts can be identified from multiple sources including configuration files, network scan files, ARP tables and hostname files. Once network device configuration files have been imported, one can import additional files to add metadata to the workspace. A hostname file is a simple text file with two columns: IP address and hostname separate by a tab.

Aux Data Loading Example

This example applies to the loading of any Aux data file but is specific to creating and loading a host file.

First, load a firewall into a workspace and create a custom view with the firewall.

Notice that four hosts are not named.  Next, create a host file, hosts.txt, to enrich the information. The host file will add a name tied to each of the hosts and also includes hosts not currently displayed.
172.30.90.50 Alice
172.30.90.51 Bob
172.30.90.42 Wendy
172.30.91.80 Sam
172.30.91.81 Carl

Make sure any hosts added to the file do not conflict with firewall interfaces or they will be merged into the firewall.

Save the host file, drag and drop the file into the workspace (or use the +Import Data function).

Click upload and the file will be imported into the workspace.

Once the file has been uploaded, it will parse in a similar fashion to config files.

Once processed, proceed to the “Manage Views” menu and select a new or existing view to add host data. Click the Auxiliary Data checkbox and then the “Save View” button.  The view will be regenerated with the data from the host file.

The updated assets will be displayed on the topology and in Asset inventory.

If for some reason a device has multiple names retrieved from multiple different file types, the additional names will be displayed in the Alias column.

Next, update the Host file again. In this scenario, we rename “Carl” to “Carly” and “Sam” to “Sammy”. The updated file is as follows:
172.30.90.50 Alice
172.30.90.51 Bob
172.30.90.42 Wendy
172.30.91.80 Sammy
172.30.91.81 Carly

Load the file into the workspace and the custom views where auxiliary data has been applied. This will update the workspace.

Host data can come from multiple sources, also hosts can appear and disappear from the network. Host data is treated as replacement data for adding and deleting hosts over time.

‍

Network and vulnerability scanners

The output from network and vulnerability scanners can be imported into a workspace to add CVE information, hosts, attributes, and port information to the topology map. We support version 1.0 <?xml version=”1.0″ ?> of the below scanners:

• Nmap – Use command nmap -oX
• Rapid 7 Nexpose,
• Tenable Nessus – Export the .nessus scan in XML format.

When exporting the report, it should be saved using the XML format to properly import into NP-View. The data extracted and imported depends on the scanner used and the data available on the network.  Below is a list of data NP-View attempts to import.

• hostnames
• addresses
• interfaces
• local interface IP’s
• local interface names
• mac
• domains
• parent
• operating systems
• vlan

Multi-Home Hosts

Multi-Home hosts are endpoints that have multiple network interfaces. If NP-View identifies hosts with multiple interfaces, the host will be duplicated on the topology with each IP address. For example, the host called 'dual-homed' can be seen three times on the map below.

To resolve this, a 'multi_home_host.txt' file can be manually generated and loaded into NP-View as auxiliary data. The file must be named 'multi_home_host.txt' and be of the following format:

192.168.135.115 dual-homed

192.168.135.114 dual-homed

192.168.135.113 dual-homed

Where the first field is the IP address and the second field is the name of the host.

When importing the 'multi_home_host.txt' and adding it to a view, the hosts will be connected as follows:

Note that the file can be named as *_multi_home_host.txt where *_ is anything preceding multi_home_host.txt. For example:

tuesday_multi_home_host.txt

web_server_multi_home_host.txt

the_big_kahuna_multi_home_host.txt

Address Resolution Protocol (ARP)

ARP files can be used to add hosts as well as MAC addresses for the hosts.  The following formats are supported:

Cisco

Use show arp to export the ARP table.  The file format will be as follows:

<hostname># show arp  

outside 10.0.0.100 d867.da11.00c1 2  

inside 192.168.1.10 000c.295b.5aa2 21  

inside 192.168.1.12 000c.2933.561c 36  

inside 192.168.1.14 000c.2ee0.2b81 97

Cisco ARP Example

Using the data set from the Hosts example, a simple ARP table has been created in the Cisco format.

Distribution# show arp    

inside 172.30.90.50 d867.da11.00c1 2    

inside 172.30.90.51 000c.295b.5aa2 21    

inside 172.30.90.42 000c.2933.561c 36    

inside 172.30.91.80 000c.2ee0.2b81 97  

inside 172.30.91.81 000c.2ecc.2b82 95

Distribution#

Loading this data into NP-View will add the MAC addresses to each host which is visible in Asset inventory.

Windows

Use arp -a > arp_table.txt to export the ARP table.  The file format will be:

Interface: 192.168.86.29 --- 0x6  

Internet Address      Physical Address      Type  

192.168.86.1          88-3d-24-76-49-f2     dynamic    

192.168.86.25         50-dc-e7-4b-13-40     dynamic    

192.168.86.31         1c-fe-2b-30-78-e5     dynamic    

192.168.86.33         8c-04-ba-8c-dc-4d     dynamic

Linux

Use arp -a > arp_table.txt to export the ARP table.  The file format will be:

? (172.18.0.3) at 02:42:ac:12:00:03 [ether] on br-d497989bc64d

? (192.168.135.200) at 00:0c:29:f6:47:bb [ether] on ens160

? (172.17.0.2) at <incomplete> on docker0

? (192.168.135.178) at 00:0c:29:f3:e2:6b [ether] on ens160

Palo Alto

Use show arp all to export the ARP table.  The file format will be:

maximum of entries supported : 2500

default timeout: 1800 seconds

total ARP entries in table : 3

total ARP entries shown : 3

status: s - static, c - complete, e - expiring, i - incomplete

interface ip address hw address port status ttl

--------------------------------------------------------------------------------

ethernet1/1 192.0.2.10 00:0c:29:ac:30:19 ethernet1/1 c 295

ethernet1/3 203.0.113.10 00:0c:29:b9:19:c9 ethernet1/3 c 1791

Route Tables

Route files are a special case in that they provide ruleset-specific enrichment data whereas the other auxiliary files listed above provide topology-specific enrichment data.

Route table – Cisco

The output of the command show route on Cisco devices can be imported into NP-View with associated configuration files.  For VRF’s, use the command show ip route vrf *. Cisco route files are handled a bit differently than the rest of the aux data as they are integrated upon import and are not considered as aux data when creating a view. Naming of the route files are not important as long as they are unique. The first row of the route file contains the <device name># command to link the route table with the correct device.

Claroty CDT

NP-View connects to the Claroty CTD (cloud or on premise) through the API.  NP-View will extract the following fields of data and map them as endpoints in NP-View.

‍

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.

Help Center

The Help Center can be found on the system menu on the upper right corner of the topology.

The Help Center will display warnings or errors identified during the import of device files.

The information in the help center is designed to provide information for the tech support team to help diagnose the issues.

There are many types of possible errors including:

1. Invalid file formats (e.g., .gif or .png)
2. Improperly formatted files (files exported as text but loaded into a word processors where extra characters are added before saving).
3. Incomplete set of files (many devices require more than one file for import this includes Palo Alto and IP tables)
4. Misconfigured files where rules or objects are undefined.

As every customer has a different environment and possible device configurations are endless.  We sometimes run into a situation where the parser cannot handle the device as configured.  When this happens, we request the customer to sanitize the config file on the NP Poral and upload the file for debug purposes.  Support from our customers is important for us to quickly remediate parsing issues unique to a device or specific file.

The Help Center provides a download for the error log which can be submitted to technical support through the support portal.
