Enabling Background Scanning (Scan Control Policy)
87 IBM Proventia Network Enterprise Scanner User Guide, Version 1.3
Enabling Background Scanning (Scan Control Policy)
Introduction
Background scanning is based on scanning refresh cycles. Refresh cycles define how
frequently you want to rerun scans for a group. Use the Scan Control policy to define the
duration of refresh cycles and to assign user-defined perspectives to scans.
Note: Background scans run during open scan windows that you define in the Scan
Window policy.
Important: This policy initiates background scanning, so you should configure it after
you have configured the other policies required for background scanning.
Scope
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:
●
An ad hoc discovery scan runs only on the group where you define the scan.
●
An 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 To enable scanning:
1. In the SiteProtector Console, set up a tab to display asset policies. (See page 74.)
2. On 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 as follows:
Field Description
Task name The name you want to appear for the scanning job in the
Command Jobs window.
Note:
This name identifies the scan when it runs, so choose a
meaningful name.
Cycle start date The date on which you want the refresh cycle to start.
Note:
Scans are scheduled in the Command Jobs window in the
SiteProtector Console at midnight at the beginning of a refresh
cycle.
Cycle duration The length (up to 3 digits) of the refresh cycle as one of the
following units:
• days
• weeks
• months
Current cycle start date The beginning date of the current refresh cycle. (Display only.)
Next cycle start date The beginning date of the next refresh cycle. (Display only.)
