The environment employs IPS/IDS and antimalware solutions to detect and respond to threats in real time, helping prevent or limit exploitation attempts. Event logs are centrally collected and analyzed to support monitoring, alerting, and detection of input-based manipulation. Static code analysis and peer reviews enforce strong input validation and error handling to prevent improperly validated inputs from causing instability, data exposure, or privilege escalation. In the event of exploitation, process isolation contains the impact within the compromised component, preventing it from affecting other processes or the broader system.", "threat_severity": "Moderate"}
