Event logs are collected and processed for centralization, correlation, analysis, monitoring, reporting, alerting, and retention. This process ensures that audit logs are generated for specific events involving sensitive information, enabling capabilities like excessive CPU usage, long execution times, or processes consuming abnormal amounts of memory. Static code analysis and peer code review techniques are used to execute robust input validation and error-handling mechanisms to ensure all user inputs are thoroughly validated, preventing infinite loops caused by malformed or unexpected input, such as unbounded user input or unexpected null values that cause loops to never terminate. In the event of successful exploitation, process isolation limits the effect of an infinite loop to a single process rather than allowing it to consume all system resources.", "threat_severity": "Moderate"}
