You can set a freeze window in Tenable Security Center to specify a time frame when you do not want Tenable Security Center to scan specific targets. This prevents remediation or ad-hoc scans from scanning assets during undesired time frames, such as during production hours. For more information about what happens to in-progress scans at the start of a freeze window, see the knowledge base article.
Freeze windows are organizational and affect all scans in the creating user’s organization. Only users with the Manage Freeze Windows permission can add, edit, or delete freeze windows.
Note: If you configure a freeze window in Tenable Security Center, it will not stop Agent scans. To stop Agent scans, configure a freeze window in each Tenable Nessus Manager.
|Name||A name for the freeze window.|
|Description||(Optional) A description for the freeze window.|
When enabled, Tenable Security Center does not scan any assets that are affected by the freeze window. If a scan does not include any assets outside of the freeze window, then the scan will abort.
When disabled, Tenable Security Center scans all assets as scheduled.
Specifies the targets you do not want to scan during the freeze window.
Note: If you select an Import Repository later in the configuration, Tenable Security Center applies your Target selections only to scans configured with that import repository. Scans configured with other import repositories still run and scan targeted assets, regardless of your freeze window Targets selection.
|Assets||If you selected Assets or Mixed as the Targets, specifies one or more Tenable-provided or user-defined asset lists that you do not want to scan during the freeze window.|
|IPs||If you selected IPs or Mixed as the Targets, specifies one or more asset IP addresses that you do not want to scan during the freeze window.|
(Optional) If you selected Assets, IPs, or Mixed as your Targets, specifies whether you want to restrict the freeze window to apply to scans configured with a specific import repository.
