How to Apply Security Backend Updates

Overview​

This article explains how to use the Security Backend Updates section in Endpoint Protector to check for and apply security updates. You can view information on recent updates, see a list of available updates, and apply updates as needed.

For the full reference, see Security Updates.

important

Security update options are only available for customer-hosted instances (for example, AWS, Google Cloud, etc.), except for Operating System and Kernel upgrades. Updates are not tested beforehand but are pulled from the official Linux repository.

warning

Netwrix does not allow on-premise (self-hosted) customers to perform backend security updates by any method other than the web UI. Applying updates through any other method is outside of Netwrix support and may cause EPP Server malfunction.

warning

Applying a backend security update has been known to crash the server on version 2601. Don't repeatedly retry a backend update if the server crashes on the first attempt — take a VM snapshot before any retry, and contact Netwrix Support immediately.

Prerequisites​

  • Test the updates in a test environment first.
  • Capture a virtual machine snapshot.
  • Make a system backup from System Maintenance in the System Backup v2 section.

Instructions​

  1. In the Endpoint Protector console, navigate to Dashboard > Live update.
  2. Select one of the available security update types and click Check Updates:
    • Security: Updates all security-related packages (Critical and High).
    • Other: Downloads and applies any update available to third-party libraries, kernel, OS packages, and MySQL database.
    • All Updates: Downloads and applies Informational and Optional/Unclassified updates.
  3. If updates are available, click Apply Updates.
important

Some updates may automatically restart the Endpoint Protector server or other sub-services in the background. If updates do not apply, create a ticket in the Support Portal for further investigation.

tip

To review the history of applied backend updates, go to the Admin Actions report and select Apply Updates under the Activity filter.
