Security policy
As shown in Figure 4, a security policy filters packets based on the specified filtering conditions
such as source/destination security zone, source IP/MAC address, destination IP address, service,
application, terminal, user, and time period. It processes matched packets according to the pre-set
policy action. If a packet does not match any policy, it will be discarded. If no filtering conditions are
configured in the security policy, the policy matches all packets.
