Always-on detections: eliminating the WAF “log versus block” trade-off

Summary

The article presents a novel approach to web application security through the introduction of always-on detections that eliminate the traditional trade-off between logging and blocking malicious traffic. By implementing Attack Signature Detection, every request is inspected for malicious payloads, providing complete visibility without sacrificing performance. The article emphasizes the importance of analyzing the entire HTTP transaction, rather than just the request, to significantly reduce false positives and uncover threats that conventional systems might miss. This new framework allows for continuous detection, enriching analytics with metadata that can be used to create custom security policies, thereby enhancing the overall security posture of applications.

Key Learnings

• 1The always-on detection framework allows for continuous monitoring of web traffic without impacting performance, providing immediate visibility into potential threats.
• 2Full-Transaction Detection correlates request and response data, allowing for a more accurate assessment of whether an attack was successful, thus reducing false positives.
• 3The separation of detection from mitigation enables security teams to analyze traffic comprehensively before applying blocking rules, enhancing the effectiveness of security measures.
• 4Custom security rules can be created based on detailed analytics, allowing organizations to tailor their defenses against specific threats and vulnerabilities.
