Nessus Network Manager
Tenable Nessus Network Manager (NNM) is a network discovery and vulnerability analysis software solution that delivers continuous network listening, profiling, and monitoring in a non-intrusive manner.
The Nessus Network Manager monitors network traffic at the packet layer to determine topology, services, and vulnerabilities and is tightly integrated with Tenable’s SecurityCenter and Log Correlation Engine (LCE) to centralize both event analysis and vulnerability management for a complete view of your security and compliance posture.
NNM Plugin Families
The NNM has two sources of “plugin” information: the .prmx and .prm plugin libraries in the plugins directory and the operating system fingerprints in the osfingerprints.txt file.
Tenable distributes its passive vulnerability plugin database in an encrypted format. This file is known as tenable_plugins.prmx and can be updated on a daily basis, if necessary. NNM plugins that are written by the customer or third parties have the extension of .prm.
The following table summarizes the Tenable NNM plugin families:
