Install a Nessus Network Monitor

Passive vulnerability scanning is the process of monitoring network traffic at the packet layer to determine topology, clients, applications, and related security issues. The Nessus Network Monitor (NNM) can also profile traffic and detect compromised systems.

NNM can:

  • detect when systems are compromised with application intrusion detection.

  • highlight all interactive and encrypted network sessions.

  • detect when new hosts are added to a network.

  • track which systems are communicating and on which ports.

  • detect which ports are served and which are browsed by each system.

  • detect the number of hops to each monitored host.
