Rule Customization

The Advanced WAF is implemented using the following different types of rules:




These rules define conditions that may indicate a suspicious request. They also specify the threat score that should be allocated to such a request. A request can match multiple MainRule rules, increasing its threat score with each match.


These rules specify allowlist conditions for safe requests, called false positives, that would otherwise be flagged as suspicious by violating a MainRule.


These rules define the thresholds for threat scores. There is a separate threshold for each type of threat. When a request threat score exceeds the threshold, some designated action may be performed, such as blocking or reporting the request.
