Configuring a Global Protection Whitelist Rule to Ignore False Alarms

Prerequisites

A website has been added to WAF.

Constraints

• If you select All protection for Ignore WAF Protection, all WAF rules do not take effect, and WAF allows all request traffic to the domain names in the rule.
• If you select Basic web protection for Ignore WAF Protection, global protection whitelist rules take effect only for events triggered against WAF built-in rules in Basic Web Protection and anti-crawler rules under Feature Library.
  • Basic web protection rules

    Basic web protection defends against common web attacks, such as SQL injection, XSS attacks, remote buffer overflow attacks, file inclusion, Bash vulnerability exploits, remote command execution, directory traversal, sensitive file access, and command and code injections. Basic web protection also detects web shells and evasion attacks.

  • Feature-based anti-crawler protection

    Feature-based anti-crawler identifies and blocks crawler behavior from search engines, scanners, script tools, and other crawlers.

• It takes several minutes for a new rule to take effect. After the rule takes effect, protection events triggered by the rule will be displayed on the Events page.
