# Configuring Defense Policies (Outbound)

- Configuring the Zone
  Before you configure an anti-DDoS policy or AntiDDoS1820-N policy, add Zones to be protected by the anti-DDoS or AntiDDoS1820-N. The ATIC Management center provides refined and differentiated filtering and protection for different Zones.
- Configuring the Zone-based Defense Policy
  After you create a Zone, configure a defense policy specifically for the Zone so that attack traffic can be blocked. When the Zone identifies abnormal traffic or is under attack, you can refer to the defense status information on the Versatile Security Manager (VSM) graphical user interface (GUI) to handle anomalies or attacks.
