Security Posture Analysis
Comprehensive Security Assessment
The current security maturity is basic with notable gaps. The use of outdated jQuery 1.7.2 exposes the site to known vulnerabilities. Absence of HTTPS enforcement and security headers reduces protection against common web attacks. No privacy or cookie policies are present, risking GDPR non-compliance. No incident response or vulnerability disclosure information is provided. The site does not collect user data via forms, limiting attack surface but also indicating limited user engagement. Overall, the security posture requires significant improvements to meet modern standards.
Strategic Recommendations
Priority Actions for Security Improvement
Upgrade all JavaScript libraries to current secure versions to mitigate known vulnerabilities.
