The Activation Code and manual plugin update buttons are only used when using PVS in a stand-alone mode (not

attached to a SecurityCenter). The Activation Code will only need to be updated when it expires. When PVS is used with

SecurityCenter, entering “SecurityCenter” in the Activation Code box will enable the ability to upload and apply the

appropriate license key to work with SecurityCenter installations.

The Offline Update allows for manually updating the plugins when the PVS host is not able to connect to the Internet.

After downloading the plugin update archive from Tenable, select the “Choose File” button and select the archive to

upload. Click the “Upload Archive” button to send the file to the PVS host, which will then update the plugins. If a new

client is part of the update, the browser needs to be refreshed to view the updated client.

The Custom Plugin Feed host is an alternate feed host. These are typically hosted on a local network to provide custom

PVS plugins.

The PVS Settings tab provides options for configuring the network settings for PVS. This is the main configuration page

that controls what network(s) are monitored or excluded, how to monitor the network, and what network interfaces PVS

has identified for monitoring.

When options are changed on this page and submitted, the PVS service on the host must be stopped and

started for them to take effect.

Memory

Sessions Cache Size

The Sessions Cache Size is the size in megabytes (MB) of the session table. Adjust

the session size as needed for the local network.

Packet Cache Size

The Packet Cache Size keyword specifies the maximum size in megabytes of the

cache that will be used to store the contents of the packets collected before

processing. By default it is set to 512 MB with a maximum size of 512 MB. When the

cache is full, any subsequent packets captured will be dropped until space in the

cache becomes available.

Monitoring

Monitored Network

Interfaces

The Monitored Network Interfaces field specifies the network device(s) to use for

sniffing packets. Devices may be selected individually or in multiples. At least one

interface must be selected from the list of available devices.
