For customers who have installed the Ubuntu version of the NP-View OVF, this package is designed to update Docker and Ubuntu to the following versions:

  • Docker version 27.1.2, build d01f264

  • Kernel version 5.15.0-118-generic

  • Ubuntu version Ubuntu 22.04.4 LTS

  • Download the update package

  • Verify the checksum: 7D510280D6901502B7210EADC284B351F49C0AE6F40D9030A99C5A6A17B6444F

Steps to Update

  1. SSH into the NP-View server

    sudo su –
cd /root/
mkdir updates
cd updates
unzip update-packages-08-14-24.zip
cd update-packages-08-14-24
export DEBIAN_FRONTEND=noninteractive && dpkg -i *.deb
reboot

The .zip and .deb files can be removed after reboot.

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.

Possible Errors During Import

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

Cleaning Up Device Configuration

When this occurs, we request the customer to sanitize the config file on the NP Portal 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.

Help Center Features

  • The Help Center provides a download for the error log which can be submitted to technical support through the support portal.
  • When we improve a data or analysis feature or fix an issue, the improvement may not be visible until new data is ingested, or another action is taken.

New Data or Warnings identified during file parsing

When we improve a parser, upon next import, we will apply the new rules and import the new or corrected data. Only the workspace where the new file(s) are imported (manual or connector) will receive the new data. To ensure the entire workspace is current, users can manually re-import data into their existing workspace.

Risks and Warnings

When we improve risk alerts, upon the next import, we will apply the new policies and requirements.

The Connectivity Matrix

The Connectivity Matrix illustrates port access between devices and interfaces. Each row or column header cell contains:

  • Interface Name
  • Alias
  • IP Address
  • Security Zone

Each cell contains 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:

  • Copy and Paste directly into Excel or Sheets
  • Take a screenshot

Segmentation Analysis via the Zone Matrix

The Zone Matrix leverages visual zones created on the topology map to create a matrix that illustrates access between these zones. This allows users to analyze and confirm segmentation and access.

Updating the NP-View Server Application

To update an existing NP-View Application, the steps are:

  1. Download the latest release Linux Installer Release from the Network Perception Portal.
  2. Login onto the NP-View server using SSH.
  3. Get root permissions using the command: sudo -i
  4. Execute the new NP-View release file using: sh NP-View_installer.sh.
  5. Follow the guided steps of the installer, which will automatically start NP-View once the update is complete.

Back-Up NP-View Database

  1. Copy database folder to a safe location.
  2. Download NP-View from the portal and install.
  3. Starting the application may take longer than usual as a one-time database maintenance operation is performed.

Rule Usage Feature

The Rule Usage feature helps network admins identify rules for potential elimination due to lack of use. From the NGFW, we extract:

  • First Hit – Timestamp of first rule usage
  • Last Hit – Timestamp of last rule usage
  • Hits Updated – Timestamp of last data refresh
  • Hits – Usage count

Once enabled, this data will be displayed in the Access rules table.
