When using a WAF like SafeLine, false positives can occur due to default rules not aligning with application behavior.
Resolving false positives involves configuring custom rules in SafeLine WAF, such as whitelists to allow specific traffic or blacklists to block malicious patterns.
Common methods for custom rule configuration in SafeLine include partial path match, exact path match, prefix match, and regex match.
Testing custom rules in SafeLine can be optimized by avoiding browser caching and understanding the matching logic for effective protection.
