Security Posture Analysis

Comprehensive Security Assessment

The current security maturity level is moderate. The website does not expose sensitive information and uses HTTPS (assumed from modern web standards, though SSL details are not explicit). However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response contacts are provided, limiting readiness for security incidents. Privacy compliance is weak due to missing privacy and cookie policies. The security culture appears informal, consistent with a personal portfolio site rather than a corporate environment. Enhancements in security headers, privacy documentation, and incident response mechanisms are recommended to improve the security posture.
