Configure ModSecurity WAF with OWASP Core Rule Set (CRS) for web application logging, tune rules to reduce false positives, analyze audit logs for attack detection, and implement custom SecRules for application-specific threats. The analyst configures SecRuleEngine, SecAuditEngine, and CRS paranoia levels to balance security coverage with operational stability. Activates for requests involving WAF configuration, ModSecurity rule tuning, web application audit logging, or CRS deployment.
Automate repetitive workflows and reduce manual effort
Example: Generate reports, summarize documents, draft communications
Save 3-5 hours per week on routine tasks
Learn new skills, understand complex topics, get expert guidance
Example: Explain concepts, provide examples, suggest learning resources
Accelerate learning and skill development by 2x
Enhance output quality through reviews, suggestions, and refinements
Example: Review drafts, suggest improvements, catch errors
Improve work quality by 30-40% with less effort
Time estimate: 15-45 minutes depending on use case complexity

ModSecurity is an open-source WAF engine that works with Apache, Nginx, and IIS. The OWASP Core Rule Set (CRS) provides generic attack detection rules covering SQL injection, XSS, RCE, LFI, and other OWASP Top 10 attacks. ModSecurity logs full request/response data in audit logs for forensic analysis and generates alerts that feed into SIEM platforms.
ModSecurity: Warning. Pattern match "(?:union\s+select)" [file "/etc/modsecurity/crs/rules/REQUEST-942-APPLICATION-ATTACK-SQLI.conf"] [line "45"] [id "942100"] [msg "SQL Injection Attack Detected via libinjection"] [severity "CRITICAL"]
