Schedule Intrusion Rule Updates

As part of the initial configuration, the system schedules daily intrusion rule updates. We recommend you review this task and make changes if necessary, as described in this procedure.

Before you begin

  • Make sure your process for updating intrusion rules complies with your security policies.

  • Consider the update's effect on traffic flow and inspection due to bandwidth constraints and Snort restarts. We recommend performing updates in a maintenance window.

  • Make sure the management center can access the Cisco Support & Download site.

Choose System (system gear icon) > Content Updates > Rule Updates.

Step 2

Under Recurring Rule Update Imports, check Enable Recurring Rule Update Imports.

Step 3

Specify the Import Frequency and start time.

Step 4

(Optional) Check Reapply all policies... to deploy after each update.

Step 5
