Enabling background scanning
Use the Scan Control policy on the SiteProtector Console to define the duration of
refresh cycles and to assign user-defined perspectives to scans.
About this task
Background scanning is based on scanning refresh cycles. Refresh cycles define
how frequently you want to rerun scans for a group.
Note: Background scans run during open scan windows that you define in the
Scan Window policy.
Important: This policy initiates background scanning, therefore you configure it
after you have configured the other policies required for background scanning.
The Scan Control policy applies to background discovery and background
assessment scans. This policy does not affect ad hoc scans. Consequently, the
behavior for ad hoc scans is different:
vAn ad hoc discovery scan runs only on the group where you define the scan.
vAn ad hoc assessment scan applies to the group where you define the scan and
to all the subgroups. This is different from background scans in that background
scanning behavior is determined by which Scan Control policy applies to each
subgroup.
Procedure
1. From the SiteProtector Console, create a tab to display asset policies.
2. In the navigation pane, select a group, and then open the Scan Control policy
for that group.
3. Select the Enable background discovery/assessment scanning of this group
check box, for the type(s) of background scanning you want to define, in the
Background Discovery and Background Assessment sections.
4. Configure background scanning for each type of scan:
Option Description
Job name The name you want displayed for the
scanning job in the Command Jobs window.
Note: This name identifies the scan when it
runs, therefore choose a meaningful name.
Cycle start date The date on which you want the scan cycle
to start.
Note: Future scans are created in
SiteProtector at midnight at the beginning of
the next refresh cycle.
Cycle duration Thelength (up to three digits) of the cycle as
in one of the following units:
vHours (for use with Enterprise Scanner 2.1
agents or later only)
vDays
vWeeks
vMonths
Current cycle start date The beginning date of the current scan cycle.
