The NNM™ Application

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 Nessus Network Monitor (NNM) 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 NNM behaves like a security motion detector on the network.

The NNM application must be activated and configured to make the system manageable via a web browser or used by SecurityCenter.

Note: Until a valid Activation Code is entered, the message Invalid/Expired Activation Code will be displayed in red on the Appliance page.

The screen below displays options available to enable and configure the NNM application with SecurityCenter.
