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
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 Desktop is a resource intensive application. For best performance, please ensure your system’s Power plan is set to High performance.
If you have administrator access, you can enable Ultimate Performance by opening the command prompt as administrator and copy paste: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 and press enter.

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
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:
Move installer to server – This may require ssh or other user account permissions
Place the file in a location you can access from the terminal
/tmp – this is a temp folder available at the root directory
/opt/np-live – this is the default NP View server root directory
You can use the “ls” command to see what is in your current directory
Log into the terminal or use SSH (Putty, PowerShell, etc.) into the Linux server
Set root level permission with the command (this will allow you type commands without adding “sudo” to each command)
sudo -I
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
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)
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:
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
There will be a message once the installation is complete
Launch a browser to navigate to the NP-View User InterfaceExample of transfer with WinSCP:
Load WinSCP – It should default to this screen:
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”.
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:
Extract the .zip archive (right click on folder and choose extract all)
Import OVF into hypervisor
Update CPU/Memory/Disk Space to meet requirements stated in KB in the hypervisor settings
Open README.txt from extracted folder for credentials
Launch the appliance and log into terminal using credentials in README.txt
NP-View Server shell script will guide you through updating the NP-Live password, the root password, and to reset encryption keys
Once complete the NP menu will appear indicating the server is ready to use.
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:
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.
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
Stop the NP-View Server (you can use the script /opt/np-live/stop_nplive.sh)
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)
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.
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.
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
Network visualization via The Topology Map is the most powerful feature of NP-View.
Once you:
Create a workspace
Import configuration files
Import supporting meta data
NP-View’s visualization engine will process your information and create a dynamic, usable network diagram, starting you at the Home View. Workspaces are broken down into views, which you can read more about here > Manage Views.
Topology Map
Based on your imported configurations, NP-View will create a map to connect and display nodes of the following types:
Firewalls (physical and virtual)
Routers (physical and virtual)
Switches
Host-Routers
Networks (subnets)
Hosts
Gateways
Border Gateways
VPN Tunnels
Unmapped Hosts and Networks
Details: Each node is represented by its own individual icon on the map, and when clicked will open a details panel with information about the selected node. From each details panel devices can be assigned a category (colored text tag) and criticality (colored ring).
Risk Display: If a device has active alerts, the number of alerts will be displayed as a red circle on the device icon.
Unmapped Gateway:
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.
Organizing the Map
On the Topology Map, users can rearrange any object or group of objects on the canvas by simply selecting and dragging a device to a new location. Device locations can be saved with the “Save Topology” button which can be found in the top center of the screen.
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 segmented into zones. See more info on zone creation.
Save Topology: 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 proceed to the selected view without saving by clicking “OK”, or they can choose “cancel” to go back and ‘Save Topology’ .
Other Topology Functions
Settings: Opens a panel with user preferences that can be set for the map. See the section below for more
Pin/ Unpin Topology: Selecting this, moving one device will cause the map to auto arrange. This can be helpful if when importing a large number of devices, the topology map initially displays with overlapping devices
Collapse/ Expand Topology Nodes: Some Topology Maps may become visually overwhelming depending on how many nodes are present. This setting will hide end points and only display Primary devices and networks
Night Mode: Sets the map to a different color scheme
Highlight Paths: Opens the Highlight Paths menu item. See the Paths article for more.
Manage Views: Opens the Manage Views menu item. See the Manage Views article for more.
Center Map: Centers the map on the screen
Topology Settings
NP-View provides a settings menu specifically for the topology. This menu can be used to show as much or as little information as you desire on the topology map. This keeps the topology map at a level of organization that suits your use.
The topology settings menu is easily accessible from the menu in the bottom right of the topology map by clicking on the gear icon.
This will open the topology settings dialog and allow users to show or hide different types of information on the fly.
Highlight Verified Assets – this setting enables or disables the verified assets feature.
Collapse Nodes By Default – this setting toggles the behavior of whether or not nodes on the topology map are collapsed when the topology is rendered.
Show Gateways with NO IP– this setting toggles the display of gateways (white gateway icons) that are defined but have no IP address assigned. The default behavior is to hide them.
Show Networks with NO IP – this setting toggles the display of networks / interfaces (white cloud icons) that are defined but have no IP address assigned. The default behavior is to hide them.
Show Only Bridge Groups - Some devices define bridge groups that show up as Networks with NO IP. If a bridge group is identified in the Interfaces table, this selection will allow for the bridge groups to be displayed while the rest of the NO IP networks are hidden.
Show Topology Elements – this setting toggles the display of topology elements that the user may wish to selectively hide for viewing or screen shots.
IP Addresses - Any IP address on the topology, even if it is the device name.
Names - Any device name that is not an IP address.
Categories - User assigned categories.
Criticalities - User assigned criticalities.
Vulnerability Shields – Icons that show vulnerabilities on nodes when scans have been imported into the workspace.
Risk Bubbles - Red risk bubbles that identify the number of risk alerts associated with each device.
Zones - User defined zones
Pinned Annotations - Annotation text assigned to individual nodes (Annotation icons still display)
Show Layer 2 Connections - Display layer 2 data inferred from layer 3 devices or PCAP / Scanner files.
The Verified Assets feature was introduced in version 5.1.0 and is designed to use Auxiliary data to verify inferred assets identified from configuration files.
The following auxiliary data files, when added to a view, can be used to verify assets:
ARP files
Vulnerability Scanners files
Claroty CDT
Auxiliary data files that are not used for verification are:
Host files
Multi-Homed Host files
Once a view is created with auxiliary data and the Asset Verification feature is enable in topology settings,
The topology will display the verified assets in blue as shown below:
When clicking on a specific asset, the info panel will display the files where the asset was identified and the verified files highlighted in blue.
Additionally, Asset Inventory will also display the verified files in the 'Created by' column and if the asset is verified or not.
Asset verification only applies to endpoints. Assets in asset inventory that are not endpoints (Firewall, Router, Switch, Gateway) will me marked as N/A in the verified column.
Clicking on the file name in the 'Created by' column will display the configuration or auxiliary data file in a popup window.
This article will provide a brief overview of the concept of workspaces in NP-View and then describe the different functions that are available for workspaces, across roles and products.
Workspaces: What are they?
In NP-View, the Workspace is the highest level of segmentation that can be applied to a group of devices for analysis and visualization. Each workspace can be thought of as an individual file, similar to a text document in a word processor.
After logging in, the first screen you will see is the Home Page.
On this page, workspaces are illustrated by individual tiles which display their title, and the compliance framework that was selected when creating that workspace. In the image below we can see that there is a workspace named demo that was made within a NERC-CIP framework.
Workspaces are sorted by the characters in their names using standard Linux conventions:
whitespace
integer
special char
uppercase [A-Z]
underscore (possibly other special chars)
lowercase [a-z]
Creating a Workspace
Administrators and Workspace Admin’s have permission to create New Workspaces.
On the Home Page click “Add a New Workspace”.
A dialog will open that allows you to name* the new workspace and to select a compliance framework for it.**
*A workspace name may only contain alphanumeric, underscore, or hyphen characters. It must have at least 3 characters and no more than 24.
**The selection of the compliance framework enables or disables compliance-specific features and reports available within the workspace.
Creating a New Workspace or opening an Existing Workspace will open the Workspace canvas
Every Workspace has three support functions accessible on the Home Page in the upper right corner of each workspace tile.
Edit – Clicking the pencil will allow you to rename the workspace.
Share – Clicking the arrow provides access to
Export – download a copy of the workspace (in a compressed format .npx file)
Transfer – change ownership of a workspace to another user
Share – allow access to a workspace
Delete – Clicking the X deletes the workspace and removes all related data
1. Edit
Administrators and Workspace Admin’s only
Clicking on the pencil will enter edit mode.
User’s can change the name, click save, and rename; or click the x to cancel the rename
2.Export
Administrators and Workspace Admin’s only
Using Export
Once export is selected, a background task will be initiated to create a downloadable image (.npx file).
This process can take several minutes depending on the complexity of the workspace.
Once processing is complete, the user can return to this screen and download the image.
The user also has the ability to delete the image from the server.
3. Workspace Import
Administrators and Workspace Admin’s can import previously saved workspace files.
By dragging and dropping the file on to the Home Page or into an open workspace.
If a user loads the backup workspace onto the workspaces page, it will be processed as if it is a new workspace. The name will be prepopulated but can be changed and while the compliance type is requested, the type may change to that of the saved workspace.
If a user loads a backup workspace into an existing workspace, the workspace contents will be replaced with the contents of the uploaded image and the workspace compliance type may be changed to the compliance types saved with the workspace.
When a workspace file is imported, processing of the risk policies is required and may take several minutes for the topology to render.
Workspaces exported from NP-View Professional Desktop can be shared with users of NP-View Professional Server (licensing rules apply).
Workspace Collaboration (Server Only)
Administrator and Workspace Admin’s have access to two workspace collaboration functions.
Share workspace
Transfer workspace
4. Share Workspace
Administrators and Workspace Admin’s can share a workspace with
all users of the same type
or to individual users
The shared users existing roles apply to the shared workspace
If a workspace is shared with a user, the workspace cannot be transferred to the shared user.
The workspace must first be unshared prior to attempting the transfer.
From the Home Page
Administrators can use the dropdown selector to view and share workspaces of all users
Workspace Admins can only view and share workspaces they have created
5. Transfer Workspace
Administrator and Workspace Admin’s can transfer a workspace to another Administrator or Workspace Admin
The transferred user’s role applies to the transferred workspace
Administrators can transfer workspaces of all users
Workspace Admins can only view and transfer workspaces they have created
NP-View can import auxiliary data from third party systems to enrich and augment 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 be displayed
Host Files
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
Note: 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. To fix this, create a host file, named 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.
Let's use 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 Note: 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, and import it into the workspace.
The Manage Views function displaying a user adding both devices and multiple Auxiliary data files to a single view.
Once processed, proceed to the “Manage Views” menu and select a new or existing view to add Auxiliary data to.
Below the Select Devices box, is the Auxiliary Data box.
Choose any of the Auxiliary Data files you've added previously. (This image is not reflective of the example but to illustrate that users may select several Aux files).
For our example a user would see a single file called hosts.txt that would contain the names we've added.
Once the the view is created the updated assets will be displayed on the topology and in the Asset Inventory (on the main menu).
The view, seen here regenerated. Note the new hostnames applied to the endpoints.
To see how the previous example can be used as a repeatable process let's update those names again, with corrections.
First, 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.
The workspace, updated a second time
Note: 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.
Note: 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 of the Asset Inventory.
Network and Vulnerability Scanner Files
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:
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 Host Files
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.
The host named 'dual-homed' repeated 3 times on the map
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:
The hosts named 'dual-homed' have been consolidated
Note: 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 commashow 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
ethernet1/1 192.0.2.10 00:0c:29:ac:30:19 ethernet1/1 c 295
ethernet1/2 198.51.100.10 00:0c:29:d7:67:09 ethernet1/2 c 1776
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.
PCAP
IN V6.0 and later, PCAP and PCAPng files can be used to enrich the topology map. NP-View will add endpoints with IP's, MAC addresses and services to the topology map within a view. The max PCAP size is 200 MB per file.
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.
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 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.
