General availability: Per Rule Actions on regional Web Application Firewall

公開日: 11月 15, 2022

Azure’s regional Web Application Firewall (WAF) with Application Gateway running the Bot Protection rule set and Core Rule Set (CRS) 3.2 or higher now supports setting actions on a rule-by-rule basis. This gives you greater flexibility when deciding how the WAF handles a request that matches a rule’s conditions. The following per rule actions are supported:

  • Allow: The request passes through the WAF and is forwarded to the back end. No further lower priority rules can block this request.
  • Block: The request is blocked and WAF sends a response to the client without forwarding the request to the back end.
  • Log: Request is logged in the WAF logs and WAF continues evaluating lower priority rules.
  • Anomaly Scoring: This is the default action for the Core Rule Set where total anomaly score is incrementally increased when a rule with this action is matched. 

To learn more about per rule action, please visit the regional WAF documentation.
