This prevents vulnerable code from reaching production and encourages our developers to follow secure coding practices. System monitoring controls play a crucial role in detecting and responding to XSS attacks by analyzing logs, monitoring user behavior, and generating alerts for suspicious activity. Meanwhile, AWS WAF (Web Application Firewall) adds an extra layer of defense by filtering and blocking malicious input before it reaches the platform and/or application. Together, these controls create a defense-in-depth approach, reducing the risk of XSS exploitation by preventing, detecting, and mitigating attacks at multiple levels.", "threat_severity": "Moderate"}
