CLI Reference

config security waf action

Use this command to configure web application firewall (WAF) actions. A WAF action is referenced by the WAF policies to define which action will be taken when policies detected attacks.

In many cases, you can use predefined profiles to get started.

Predefined actions

Description

alert

WAF policies will only leave a log and didn’t touch the attack traffic

block

WAF policies will leave a log, drop current attack session by HTTP 403 message and block attacker (according the attacker’s IP address) for 1 hour

deny

WAF policies will leave a log, drop current attack session by HTTP 403 message

silent-deny

 

WAF policies will drop current attack session by HTTP 403 message, without a log

The configurations for these actions are shown in the examples that follow. If desired, you can create user-defined actions.

Before you begin:

  • Usually, predefined actions are enough for normal usage, and most predefined WAF policies reference the predefined actions. After your define your own action, you must specify it in your WAF policies to let it take effect.
  • You must have read-write permission for security settings.
