Security checks
Each check inspects a different part of tp.edu.sg's public security setup. Green means healthy, yellow needs attention, red is a problem.
Security Headers
Only 2/5 security headers present. Missing: X-Frame-Options, Referrer-Policy, Permissions-Policy. This exposes the application to clickjacking, MIME-sniffing, and other client-side attacks.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_128_GCM_SHA256 (128-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Known Breaches
No known breaches found in public disclosure databases.
HSTS Header
HSTS enabled: max-age=63072000. includeSubDomains present. Missing preload directive.
CVE Exposure
No server software versions detected in HTTP response headers. This is good practice (version hiding) but means CVE exposure cannot be assessed from external signals alone.
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); SPF record present with hard-fail (-all); DKIM configured (selectors: selector1, selector2, dkim).
Certificate Hygiene
Strengths: Certificate valid, 150 days remaining; Issued by Sectigo Limited.
DNS Configuration
Strengths: 2 nameservers configured (tpgate4.tp.edu.sg., tpgate3.tp.edu.sg.); 1 MX records present; DNSSEC enabled; Zone transfers properly restricted.
