How to Create IPS Policies

  • Last updated on

Configure IPS scanning policies to control the behavior of the IPS engine when an attack is detected. By default, all access rules use the default IPS policy. You can also customize the default settings or create custom IPS policies to apply to your access rules. Each of the created policies can be applied individually.

    • Description – Enter a description for the policy.
    • Action – Select an action.
      • Do Not Scan– IPS does not scan traffic matching the criteria.
