About intrusion system signatures

You can upload custom signatures to the Smoothwall Filter and Firewall and Sourcefire Vulnerability Research Team (VRT) signatures and make them available for use in Intrusion Detection and Prevention policies. Any custom signatures you upload, or Sourcefire VRT signatures you download to the Smoothwall Filter and Firewall is listed on the Policies page. To deploy intrusion policies, see our help topics, Deploying intrusion detection policies and Managing intrusion prevention system policies.
