Configuring an attack protection policy
In an attack protection policy, you can specify the signatures for attack detection and the corresponding
protection measures according to the security requirements of your network.
Different types of attack protection policies have different configurations, which are described below in
terms of single-packet attacks, scanning attacks, and flood attacks.
Configuring a single-packet attack protection policy
The single-packet attack protection function determines whether a packet is an attack packet mainly by
analyzing the characteristics of the packet. It is usually applied to security zones connecting external
networks, and inspects only the inbound packets of the security zones. If detecting an attack packet, the
device outputs an alarm log by default and, depending on your configuration, drop or forward the
packet.
To configure a policy for preventing single-packet attacks:
