Security Posture Analysis
Comprehensive Security Assessment
The website demonstrates a moderate security maturity level with HTTPS usage and a robust cookie consent framework supporting GDPR compliance. However, the absence of visible security headers and explicit security or incident response policies indicates room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts like Google Tag Manager and Analytics is standard but requires ongoing monitoring for security risks. The lack of a vulnerability disclosure or security.txt file suggests limited formal vulnerability management. Overall, the security posture is adequate for an educational institution but could be enhanced with additional policies and technical controls.
Strategic Recommendations
Priority Actions for Security Improvement
Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection against common web attacks.
