This rule is designed to detect segmentation fault errors generated by Apache web server processes. When an Apache worker process experiences a segmentation fault, it typically results in the process crashing, which is logged in the error.log file. This condition indicates critical errors that could lead to service disruptions, unauthorized access points, or exploitation opportunities if not monitored and corrected. The detection mechanism relies on searching the Apache error logs for specific keywords associated with segmentation faults, ensuring immediate alerts to administrators for swift action. The rule categorically flags these incidents, considering their potential impact on web service availability and security.
