What problem does it solve?

Web applications protected by ModSecurity with the OWASP CRS often generate noisy logs and frequent false positives, which can obscure true threats and complicate incident response. This Skill provides a structured workflow to analyze the ModSecurity serial audit logs, identify high-frequency rule firings, and implement safer exclusions to maintain security visibility without destabilizing operations.

Core Features & Use Cases

• Audit-log analysis: parse serial audit logs to extract rule matches, severities, and anomaly scores for actionable insights.
• False-positive detection & exclusions: identify frequently triggered rules across many IPs and generate SecRuleRemoveById directives to reduce noise.
• Tuning reports & automation: summarize findings by category and severity, and produce a ready-to-deploy exclusion snippet for CRS tuning.

Quick Start

Run the ModSecurity audit log agent against your audit log to produce a tuning report and exclusion recommendations.
