Security checks

Each check inspects a different part of gov.sg's public security setup. Green means healthy, yellow needs attention, red is a problem.

TLS Configuration
TLSv1.2 negotiated. Issues: TLS 1.2 negotiated (1.3 preferred).
Needs work
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest). Issues: No SPF record found; No DKIM records found for common selectors (may use non-standard selectors).
Needs work
HSTS Header
HSTS enabled: max-age=31536000. Missing includeSubDomains. Missing preload directive.
Healthy
Security Headers
4/5 security headers present. Missing: Permissions-Policy.
Healthy
Known Breaches
No known breaches found in public disclosure databases.
Healthy
CVE Exposure
Detected technologies: AmazonS3, Proxy/CDN. (Proxy/CDN detected but excluded from CVE matching — upstream infrastructure). No version information exposed — CVE matching not possible (this is good practice).
Healthy
DNS Configuration
Strengths: 4 nameservers configured (dsany2.sgnic.sg., pch.sgzones.sg., dsany3.sgnic.sg., dsany4.sgnic.sg.); DNSSEC enabled; Zone transfers properly restricted.
Healthy
Certificate Hygiene
Strengths: Certificate valid, 250 days remaining; Issued by GlobalSign nv-sa.
Healthy
Recommended actions
2 items

Steps to improve gov.sg's security grade, ranked by impact.

1
Strengthen email authentication configuration
Impact: 2–4 Hours
HIGH
Email authentication is partially configured for gov.sg but has gaps. Actions needed: add SPF record; configure DKIM. Until DMARC enforcement is active, spoofed emails may still reach recipients.
Compliance impact
NIST CSFPR.AC-7
Email authentication is a required access control
How to fix this
1
Add SPF record if missing: v=spf1 include:_spf.google.com -all
2
Configure DKIM and publish public key in DNS
3
Verify with: nslookup -type=txt _dmarc.gov.sg
2
Upgrade to TLS 1.3
Impact: < 1 Hour
LOW
gov.sg negotiated TLSv1.2. TLS 1.2 is still compliant under all major security frameworks and is not a vulnerability. TLS 1.3 offers faster handshakes and removes legacy cipher negotiation. This is a best-practice improvement, not a compliance gap.
How to fix this
1
Update web server config to prefer TLS 1.3 (nginx: ssl_protocols TLSv1.2 TLSv1.3)
2
Verify: openssl s_client -connect gov.sg:443 -tls1_3
