Add missing security headers (CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy)
4 of 5 recommended security headers are missing on tpg.com.sg: CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy.

Compliance Impact
PCI-DSS 4.0Req 6.4.1
Security headers are required application controls
OWASPSecure Headers
Recommended baseline for web applications
Remediation Steps
1
Add Content-Security-Policy header (start with report-only to avoid breakage)
2
Add: X-Frame-Options: DENY (or SAMEORIGIN if you use iframes)
3
Add: Referrer-Policy: strict-origin-when-cross-origin
4
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
5
Verify with: curl -sI https://tpg.com.sg | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
3
Review potential CVE exposure in detected software
Software detected on tpg.com.sg has potential CVE matches. Review the specific CVEs and confirm whether the installed version is affected.
Remediation Steps
1
Review matched CVEs and confirm installed versions
2
Update software if vulnerable versions are confirmed
3
Consider hiding version information in server headers
4
Review certificate configuration
Certificate issues found for tpg.com.sg: wildcard certificate in use. Wildcard certificates have a broader blast radius if compromised. Ensure auto-renewal is configured to prevent expiry. These are operational hygiene items, not immediate security risks.
Remediation Steps
1
Verify auto-renewal is configured (Let's Encrypt: certbot renew --dry-run)
2
Consider replacing wildcard cert with individual certs for critical subdomains
3
Consolidate certificate issuance to 1–2 trusted CAs
