A defense-in-depth monitoring strategy includes perimeter firewalls and endpoint protection services that detect and respond to threats in real time, helping prevent or limit exploitation attempts. Robust input validation and error handling ensure all user inputs are thoroughly validated, supporting consistent and secure system responses.", "threat_severity": "Moderate"}
