Scan Scheduling

In JSA Vulnerability Manager, you can schedule the dates and times to scan your network assets for known vulnerabilities.

You must have the correct license capabilities to perform the following scanning operations. If you need assistance to obtain a new or updated license key, contact your Juniper Customer Support.

Scan scheduling is controlled by using the When To Scan pane, in the Scan Profile Configuration page. A scan profile that is configured with a manual setting must be run manually. However, scan profiles that are not configured as manual scans, can also be run manually. When you select a scan schedule, you can further refine your schedule by using operational windows to configure allowed scan times.

Choose one of the following scheduling options:

  • Manual

  • Run Once

  • Daily

  • Weekly

  • Monthly

  • Advanced

    Use cron expressions to create schedules, for example, 9:00 AM every Monday through Friday, or 3:30 AM the first Friday of every month. Cron expressions give you the ability to create irregular scan schedules. Schedule a maximum of one scan per day.

Be aware of the impact of changes in Daylight Saving Time on your Run Once, Daily, Weekly, and Monthly scan schedules. For example, on the 27th of March 2016, clocks in the UK go forward by 1 hour at 1:00 AM, so any scans that are configured to run between 1:00 AM and 1:59 AM on the 27th of March 2016 run between to 2:00 AM and 2:59 AM.

Advanced scan schedules that are configured to run between 1:00 AM and 1:59 AM on the 27th of March 2016 are skipped and do not run. All subsequent scans run at the scheduled times.
