Configure Tenable Nessus Network Monitor in Tenable Core

Tenable Tenable Nessus Network Monitor (Tenable Nessus Network Monitor) is a network discovery and vulnerability analysis software solution, delivering real-time network profiling and monitoring for continuous assessment of an organization’s security posture in a non-intrusive manner. The Tenable Nessus Network Monitor monitors network traffic at the packet layer to determine topology, services, and vulnerabilities. Where an active scanner takes a snapshot of the network in time, the Tenable Nessus Network Monitor behaves like a security motion detector on the network.

Activate and configure the Tenable Nessus Network Monitor application to make the system manageable via a browser, or used by Tenable Security Center or Tenable Vulnerability Management.

Installation Info

The Tenable Nessus Network Monitor Installation Info section provides information for the Tenable Nessus Network Monitor application. Users can view the URLs, Service Status, License, Application version, and Binary version.

Webserver Authentication

The Web Server Authentication section controls the configuration of the SSL Client Certificate authentication permissions. The two options are password or SSL Client Certificate. This setting controls the option available for users to log into the Tenable Nessus Network Monitor server via password authentication or SSL client certificate.

  • The SSL Client Certificate option configures the Tenable Nessus Network Monitor web server to accept only connections from browsers that present a valid SSL client certificate. The web server rejects other connection attempts, with the exact message displayed dependent on the browser in use.
  • The password option configures the server to ignore any SSL client certificates but allows the browser connection. This is the default setting and works with most browsers without issue.
