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.
Windows control panel:
First Login
Upon first login, NP-View Desktop will require you to create an administrator account. Fill in the required information and click the “Create the NP-View administrator account” button. The password can be as simple or as complex as the user desires but needs to be at least 8 characters.
Local authentication is for users who wish to add an additional layer of protection. With this, the user can use whatever e-mail address and password they choose. If the user logs out of the system, the user id and password will be required upon subsequent application launches. Otherwise, the session remains open and authentication is not required.
Read and accept the user agreement.
Next, you will need to enter your license key. Once input, click the “Add license key” button.

TCP/8080: access to NP-View connectors Web UI through HTTP
Firewall Rules
The source IP should be the client workstation that will access NP-View and the destination IP should be the NP-View Linux server.
Downloading NP-View Server
Sign up on the Portal website to download the latest version of NP-View server and the license key. A SHA256 checksum is supplied with each download by clicking on the “show checksum” link. You can calculate the checksum on the files you download to verify their integrity:
Windows 10/11 using Powershell: Get-FileHash /the/full/path/to/your/file/name/extension | Format-List
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)
Change Management provides the Compliance Team (Compliance Officer, Compliance Analysts) with capabilities that allow for:
Transitioning from point-in-time risk assessment to 24/7 with automated notification.
Automating the change review process using ticketing system integration and sandboxing.
Leveraging “time machine” to navigate through the network evolution and compare points in time.
Transition to 24×7 Monitoring
Connectors facilitate the configuration of connections to poll devices on a schedule, importing the latest configurations for analysis and automatically analyzing the information within selected workspaces to identify changes and potential risks.
Automated change review process
Change tracking automatically records configuration changes and provides the user with the ability to review changes made to the system and review the potential impact of the changes.
Network risks related to configuration changes are identified by best practices and user defined rules in the Policy manager. When a potential risk is identified, it is logged in the “Risks and Warnings” table and assigned a criticality (High, Medium, Low) based on the identifying policy.
Notifications allow users to setup notifications based on complex rules and to have those notifications delivered to multiple services on a schedule to email, syslog or ticketing systems. Notifications can be triggered by configuration changes or network risks.
The Network Sandbox is an isolated workspace that aids network engineers and infrastructure managers with the evaluation of proposed changes to system configurations, operating system upgrades or hardware replacement without affecting the production network. Our network modeling platform provides the ability to evaluate proposed changes to network devices by importing modified configuration files, evaluating the changes against policies, best practices, and regulations, and reporting on risks and vulnerabilities. Additionally, changes can be reviewed and compared, paths and connectivity can be analyzed, compliance reports can be run and reviewed.
Comparison Analysis
Tracking changes over time provides a rich data source for analysis. Comparison Analysis allows the user to review two points in time to identify changes across the system including assets, rules, objects, and paths.
Vulnerability Prioritization provides the Network Security Team and Compliance Team with capabilities that allow users to:
Align network architecture understanding and break silos through a single pane of glass
Train first responders and harden defenses via realistic attack scenario simulation
Prioritize vulnerability mitigation faster
Network Architecture Understanding
Monitoring for indicators of compromise allows organizations to better detect and respond to security compromises. When the security team discovers a potential compromise, NP-View can assist with incident response by quickly identifying critical paths to the compromised system.
For example, critical host H-192.168.1.103-32, a database server on the network, is experiencing increased reads.
Train First Responders
Users can be trained to use NP-View to quickly assess the situation. NP-View shows each host with the inbound and outbound paths. In this example, the inbound port, 443, is the likely target for the increased database activity.
Stepping stones are hosts in a network which could be compromised and used by malicious attackers to perform lateral movements. Attackers hop from one compromised host to another to form a chain of stepping stones before launching an attack on the actual target host.
Using the stepping stone analysis, the security team can quickly identify the paths of concern and the number of steps away from the compromised system or other important assets and can quickly prioritize a remediation plan.
The Connectivity Matrix illustrates port access between devices and interfaces. This allows users to analyze and confirm communication between interfaces.
Each row or column header cell contains four pieces of information.
Interface Name
Alias
IP Address
Security Zone
Each cell will contain connectivity information
Red pill: Denied – No access
White pill: IP, TCP, UDP/Any – open access
Green pill: Port specific access
The Connectivity Matrix is accessible from the device Info panel
Saving the Matrix
Two paths to save and document The Connectivity Matrix for your organization to use as an artifact:
This article will focus on the Connectivity Paths 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.
Connectivity Paths
This report provides a summary of network paths and their analysis results. Connectivity paths are created during the analyze process and are only available within a view. See this article for an overview of views.
The connectivity paths table provides a detailed explanation of the flow of information through the topology. It describes the source and source node, destination and destination node, as well as the port, protocol and service. The rue sequence traverses the access rules used to complete the path and the path sequence is the sequence of hops the path takes.
By clicking on a specific rule sequence from within the + box, the associated access rule can be displayed for review and comment.
Connectivity Paths Columns
Destination: (PATH_DST_IP_BEGIN : PATH_DST_IP_END) IP address range of the destination
Destination Node: (PATH_DST_NODES) device name or IP address of the destination node
Path Number: internally generated value used as a marker for each path.
Path Sequence: (PATH_SEQUENCE) List of IP address or devices traversed by the path from source to destination.
Port: (PATH_SRC_PORT_BEGIN ) The port that is open along the path
Protocol: (PATH_PROTOCOL) The protocol enabled on the path
Rule Sequence: (PATH_RULE_SEQUENCE) Access list sequence of rules and reference line number within the configuration file
Service: (PATH_SERVICE) The service that corresponds to the open port.
Source: (PATH_SRC_IP_BEGIN : PATH_SRC_IP_END) IP address range of the source
Source Node: (PATH_SRC_NODES) device name or IP address of the source node
This interactive report, accessible from the main menu, provides a network path comparison between two points in time.
When a configuration file is added to the system and is different from the previously imported file, a new “Version” is created.
The user can select two versions to compare. The resulting table will display the changes between the two files. Removals are shown in the left column and additions are shown in the right column.
*Compare Path History 0pen and two versions selected
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.

Additional Instructions
Collecting Data from the Device Console
+
Collecting configuration information from the device console can be an easy way to get the device data.
Following the below rules will help ensure success when importing the files into NP-View.
Note that not all data can be retrieved from the console. Please review the section for you specific device for additional instructions.
Run the command from the console.
Copy the text to a plain text editor. Do not use Word or any fancy text editor as it will inject special characters that we cannot read.
Review the file and look for non text characters like percent encoded text or wingdings like characters. These will break the parser.
Save the output of each command in a separate file and name it after the device so that NP-View can properly attribute the files. For example: firewall1_config.txt, firewall1_arp.txt, firewall1_route.txt
For Palo Alto files, there are specific naming requirements, please see the Palo Alto section for additional information.
Some config files contain very long strings. Line wrapping due to the window size of the terminal will break the parser. If using a terminal like Putty, please ensure the terminal is set to maximum width.
config system console set output standard end
Finally, if you encounter a parsing error when loading the files and want to upload the files to Network Perception using the portal, please sanitize all files at the same time so that we can keep the data synchroized across the files.
Berkeley Software Distribution (BSD)
+
BSD has three firewalls built into the base system: PF, IPFW, and IPFILTER, also known as IPF FreeBSD
IP Firewall (IPFW): Default rules are found in /etc/rc.firewall. Custom firewall rules in any file provided through # sysrc firewall_script=”/etc/ipfw.rules”
IP Filter also known as IPF: cross-platform, open source firewall which has been ported to several operating systems, including FreeBSD, NetBSD, OpenBSD, and Solaris™. Name of the ruleset file given via command ipf -Fa -f /etc/ipf.rules
IP Filter (IPF): Use /etc/ipf.conf to allow the IPFilter firewall
BSD and similar systems (e.g., Linux) will use the same names for interfaces (eth1, eth2, em1, em2, carp1, carp2, etc.). The parser might be confused if the user imports interface files and packet filter configs from different systems at the same time resulting in a combined system instead of individual devices. To prevent this, the user should group all files by host, making sure to name the ifconfig file after the hostname (i.e. host1_interfaces.txt).
Free BSD Example
Below is an example of a 2 host FREE BSD system containing FW1, host1 and host2. The user should import the files in each section as a separate import. fw1 – first data set import (all available files imported together)
pf.conf (required file) (note, can be named differently, e.g., FW1.txt’)
obsd_fw1_interfaces.txt (required file) (note that the parser keys on the “_interfaces” string”. Text before “_interfaces” will be used to name the device. In tis example ‘obsd_fw1’)
hostname.carp1
hostname.carp2
hostname.hvm2
hostname.hvm3
hostname.hvm4
table1
table2
host1 – second data set import (all available files imported together)
pf.conf (required file) (note, can be named differently, e.g., host1.txt’)
host1_interfaces.txt (required file) (note that the parser keys on the “_interfaces” string”. Text before “_interfaces” will be used to name the device. In this example ‘host1’)
hostname.em1
hostname.carp1
host2 – third data set import (all available files imported together)
pf.conf (required file) (note, can be named differently, e.g., Host2.txt’)
host2_interfaces.txt (required file) (note that the parser keys on the “_interfaces” string”. Text before “_interfaces” will be used to name the device. In this example ‘host2’)
table1
table2
The only required files are the config file (can be named something other than pf.conf) and the ifconfig file. hostname files are optional (unless they contain description of interfaces not in the ifconfig file). Table files contain a list of IP addresses that can be manipulated without reloading the entire rule set. Table files are only needed if tables are used inside the config file. For example, table persist { 198.51.100.0/27, !198.51.100.5 }
Legacy Fortinet Support
+
Support for Fortinet through 6.2 ended September 2023. Please note that no upgrades to these parsers will be made.
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.
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:
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.
Legacy Palo Alto PanOS Support
+
Support for Palo Alto PanOS prior to V9.1 are no longer supported. Please note that no upgrades to parsers will be made for unsupported devices.
Legacy Check Point R77 Support
+
Support for Check Point R77.30 ended in May of 2019. Please note that no upgrades to this parser will be supported if it fails to operate as expected. Below are the instruction for manually exporting R77 files.
Check Point R7x version store configuration information in flat files on the management server’s filesystem. The file location is different when using a multi-domain environment.
When using Checkpoint R77 management server, the required files can be found here:
/etc/fw/conf/objects_5_0.C
/etc/fw/conf/rulebases_5_0.fws
/etc/fw/conf/identity_roles.C (optional)
Load all of the retrieved files at the same time into NP-View.
When using a Multi Domain environment, the required pairs of objects and rule base files are typically stored in: $MDSDIR/customers/
If you have trouble locating the files, you can use the command: find / -name “rulebases_5_0.fws” -ls to locate the files.
All configs in these 3 locations are required (not just one)
One Global Database, located in directory: /var/opt/CPmds-R77/conf
One Multi-domain Server (MDS) database, located in directory: /var/opt/CPmds-R77/conf/mdsdb
The contents of the Domain Management Server databases (DMS), located in directory: /var/opt/CPmds-R77//CPsuite-R77/fw1/conf/ which include:
object
rulebase
/object
Load all of the retrieved files at the same time into NP-View.
Legacy Check Point R80 Support
+
Support for Check Point R80 through R80.40 ended April of 2024. Please note that no upgrades to these parsers will be made.
Cisco FTD
+
NP-View supports Cisco FTD through the output of “show running-config”command. However, it is important to note that Cisco FTD includes network filtering policies documented outside of the running configuration. This section explains where to find those policies.
As of version 6.1, Cisco FTD includes a Prefilter Policy feature that serves three main purposes:
Match traffic based on both inner and outer headers
Provide early Access Control which allows a flow to bypass Snort engine completely
Work as a placeholder for Access Control Entries (ACEs) that are migrated from Adaptive Security Appliance (ASA) migration tool.
The feature has 2 primary use cases:
For use with Tunnel Rule Types
For bypassing the Snort engine
These prefilter rules are part of the FTD configuration and are displayed via the “show running-config” command on the FTD. They manifest in the NP-View Access Rule table as a Permit IP with:
Source = any
Destination = any
Service = IP/any to any
As a result, the NP-View Rule Policy engine flags these rules as a high risk alert.
In the operation of the FTD, if a packet meets the prefilter policy, it is then evaluated by a secondary set of rules in the Snort engine or applied directly to the tunnel. The Snort rules are not part of the output of the of the “show running-config” output from the FTD. These rules are established, maintained and viewed on the FMC (management server), but are not readily available via the FTD CLI interface.
In the context of an audit during which evidence around these prefilter rules is requested, we recommend documenting that these rules are a default configuration for the system and we also recommend generating a FMC PDF Policy report to explain the flows of traffic within the FTD configuration. For more information, please refer to the Cisco FTD Prefilter Policies documentation.
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
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.

Additional Connector Instructions
Service Account
+
The use of service accounts is a recommended best practice when connecting to devices through connectors. The service account can be read-only and must have API privileges. When entering credentials related to an Active Directory domain, it is recommended to enter the username using the format account@domain.xyz instead of domain.xyzaccount as the backslash can cause unexpected issues.
For R80, we recommend creating the service account in the SmartCenter (not Gaia) ensuring the account provides access to the Web API.
AWS
+
The fields required for the AWS connector can be found at:
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 to NP-View:
Claroty
NP-View
name
Name
ipv4
IP Address
vendor
OS
mac
MAC Address
protocol
Service
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.
Device Selection
+
CheckPoint and Palo Alto network management systems provide files with multiple devices. The connectors for these systems allow for the selection of individual devices to load into NP-View. The user can input the names of the devices, one per line, or select the “Retrieve device list” button to be provides a selection list.
Forescout
+
If Forescout is truncating the data imported into NP-View, use the following command on Forescout to extend the size of the retrieved file: fstool set_property fs.np.field.string.limit.def YYYY where YYYY represents the number of lines to import (e.g., fstool set_property fs.np.field.string.limit.def 25000)
Firewall rules (`gcloud compute firewall-rules list –format=json`)
Instances (`gcloud compute instances list –format=json`)
Subnets (`gcloud compute networks subnets list –format=json`)
Routes (`gcloud compute routes list –format=json`)
VPN Gateways (`gcloud compute vpn-gateways list –format=json`)
VPN Tunnels (`gcloud compute vpn-tunnels list –format=json`)
Samba
+
Network Perception suggests the following when setting up the SMB connection.
Create a read-only user in Active Directory or on the SMB server.
Determine the available share (Get-SMBShare” in Windows PowerShell) or create a new one.
Share the SMB folder containing the Configuration files with the read-only user. For example:
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:
Path to Root Folder – Directory you want to be the root folder relative to your default SMB root folder.
Recursive Search – Whether or not to search recursively starting at the connector’s root folder.
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.
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.
SSH and Samba for HA Groups
+
NP-View has the ability to handle HA Groups.
As a best practice, if using SSH shares, it is best to erase the entire folder and replace with the config files from the current active devices. It is also a best practice to name the HA devices similarly for comparison. For example:
Pittsburgh_FW1
Pottsbirgh_FW2
etc.
For Samba shares, a similar method should be used but, the SMB connector has an extra feature of navigating date labeled folders.
Refer to the Samba section for details.
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:
whitespace
integer
special char
uppercase [A-Z]
underscore (possibly other special chars)
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.
Connector for Forescout
+
The Connector for Forescout 8.1 and later enables integration between CounterACT and NP-View such that network device configuration files managed by CounterACT can be automatically imported into NP-View and aggregated into specific workspaces. Currently, Cisco switches are supported through the Forescout Switch Plugin.
Download the Forescout Extended Module for NP-Vie from https://updates.forescout.com.
Start your Forescout Console and login into Enterprise Manager.
Then open “Options”, select “Modules”, and install the fpi.
To request additional support for this connector or to request support for other devices, please contact support@network-perception.com.
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:
Connectors fails to initiate connection to outside devices
+
In some instances, the Linux distribution is preventing the connectors (Docker) from initiating connections to outside devices. The solution is to update the firewall settings on the Linux distribution using the following commands:
The NP-View Connector for Cisco uses a read-only SSH connection to collect the output of the show running-config command. It is best practice to create a dedicated read-only user on your Cisco devices when configuring connectors. Here are the commands to only give the minimum permissions needed for this user:
conf t aaa authorization command LOCAL privilege show level 2 mode exec command running-config privilege cmd level 2 mode exec command terminal username $USERNAME password $PASSWORD priv 2 end
Bulks Start Parameters
+
To help balance the processing load of managing multiple connectors and improve user experience on the topology map, the bulk start function can be scheduled to off hours using system parameters. The docker-compose.yml file contains two parameters for the bulk system start function in the monitor: environment: section
connBulkStartTime=21:00:00 # defines the start time for the connectors, format is Hours:Minutes:Seconds, 24 hour clock.
connBulkStartSpread=00:15:00 # defines the connector start stagger, format is Hours:Minutes:Seconds
Deleting Connectors
+
Connectors can be deleted by entering the connector group name and passphrase to gain access to the connector. The connector can be deleted by selecting the trash can in the upper right corner.
If the passphrase is forgotten, the connector can be forcefully deleted by the Linux Admin by removing the connector file from the folder
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:
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
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.
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 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.

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