Settings Options

Parameter

Description

Basic

Scan Zone

Note: If your organization's Distribution Method setting is Locked Zone, you cannot modify this setting. If your organization's Distribution Method setting is Automatic Distribution Only, Tenable Security Center automatically chooses one or more scan zones and hides this setting.

Specifies the scan zone you want to use to run the scan. Depending on your organization's Distribution Method setting, you can select one of the following:

  • An available zone — use a single scan zone to run the scan.

    Note: If you select a single scan zone, Tenable Security Center ignores the ranges in the scan zone and scans all of the targets you specify in the scan configuration.

  • Automatic Distribution — allow Tenable Security Center to choose the best scan zone to run the scan.

For more information, see Organizations and Scan Zones.

Import Repository

Specifies the repository where Tenable Security Center imports the scan results. Select a Universal repository to receive IPv4 or IPv6 results appropriate to the scan. For more information about repositories, see Repositories.

Advanced

Immediately remove vulnerabilities from scanned hosts that do not reply

If a previously responsive host does not reply to a scan, Tenable Security Center removes the host's vulnerabilities from the cumulative database. If the host has vulnerabilities in the mitigated database, they remain in the mitigated database.

  • If you enable this option, the system removes the vulnerabilities immediately after the scan completes.
  • If you disable this option, the system removes the vulnerabilities according to the interval set in the Number of days to wait before removing dead hosts option.

Max scan duration (hours)

Specifies the maximum number of hours you want a scan to run. If a scan reaches this threshold, the scan stops and Tenable Security Center discards the scan results.

Inactivity timeout duration (hours)

Specifies the maximum number of hours you want a scan to be inactive before it times out.

The value for Inactivity timeout duration must be less than the value for Max scan duration.
