Security Posture Analysis
Comprehensive Security Assessment
The website demonstrates a mature security posture with enforced HTTPS and privacy-conscious Google Analytics configuration. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces its defense-in-depth. No vulnerability disclosure or incident response information is provided, which limits transparency and readiness for security incidents. The site does not expose sensitive data or use vulnerable libraries visibly, indicating good maintenance practices. To enhance security maturity, the school should implement security headers, publish a security policy, and establish clear incident response contacts. Privacy compliance gaps, especially regarding cookie consent, should be addressed to meet GDPR requirements fully.
Strategic Recommendations
Priority Actions for Security Improvement
Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
