The PVS Application
Tenable’s Passive Vulnerability Scanner (patent 7,761,918 B2) 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 Passive Vulnerability Scanner (PVS) 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 PVS behaves like a security motion detector on the network.
The PVS application must be activated and configured to make the system manageable via a web browser or used by SecurityCenter.
Until a valid Activation Code is entered or a License Key is provided for the PVS scanner to be managed by SecurityCenter, 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 PVS application with SecurityCenter:
