Nessus Scanner Details
When the “Detail” button is clicked, information about the selected scanner is displayed. The information includes the
basic information of name, description, IP address or hostname, port, username used to connect to the scanner, and
when the scanner was created and last modified. The Nessus scanner version, web server version, type, and zones it is a
part of are also displayed. The number of active scans (load) the server is performing is displayed and updated every 15
minutes, as well as the current SecurityCenter plugin set, the plugin set the Nessus scanner is currently using for
scanning, and which plugin set is currently loaded.
The Scanner Plugin Set may show a difference between the “Current” set and the “Loaded” set. This occurs
when plugins are updated but the Nessus scanning engine has not been restarted to run the newest plugins.
Scan Zones
Scan Zones define the IP ranges associated with the scanner along with organizational access. SecurityCenter allows
defined Organizations to be configured with two different scan zone modes: “selectable” and “forced”. If an Organization is
in “selectable” mode, any available zones can be associated with the Organization and made available to users for
scanning configuration. If an Organization is in “forced” mode, the selected zone will always be used for every scan
performed by users in that Organization.
