Security checks
Each check inspects a different part of uob.com.sg's public security setup. Green means healthy, yellow needs attention, red is a problem.
DMARC / Email Security
Issues: No DMARC record found — email spoofing is not prevented; No SPF record found; No DKIM records found for common selectors (may use non-standard selectors).
TLS Configuration
TLSv1.2 negotiated. Issues: TLS 1.2 negotiated (1.3 preferred).
Security Headers
3/5 security headers present. Missing: Referrer-Policy, Permissions-Policy.
Known Breaches
No known breaches found in public disclosure databases.
HSTS Header
HSTS enabled: max-age=35768000 with includeSubDomains and preload. Meets best-practice configuration.
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.
DNS Configuration
Strengths: 8 nameservers configured (a26-67.akam.net., secdns.starhub.net.sg., a28-65.akam.net., a11-65.akam.net.); 3 MX records present; DNSSEC enabled; Zone transfers properly restricted.
Certificate Hygiene
Strengths: Certificate valid, 302 days remaining; Issued by GlobalSign nv-sa.
Recommended actions
3 items
Steps to improve uob.com.sg's security grade, ranked by impact.
1
Set up email authentication (DMARC, SPF, DKIM)
Without email authentication, anyone can send emails that appear to come from uob.com.sg. This is the most common vector for phishing attacks targeting employees and customers. DMARC, SPF, DKIM are not configured.
Compliance impact
NIST CSFPR.AC-7
Email authentication is a required access control
ISO 27001A.13.2.1
Information transfer policies require email security controls
HIPAA§164.312(e)
Transmission security for electronic PHI
How to fix this
1
Add SPF record to DNS: v=spf1 include:_spf.google.com ~all (adjust for your email provider)
2
Configure DKIM signing with your email provider and publish the public key in DNS
3
Add DMARC record: v=DMARC1; p=quarantine; rua=mailto:[email protected]
4
Monitor DMARC reports for 2–4 weeks, then upgrade policy to p=reject

2
Upgrade to TLS 1.3
uob.com.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 uob.com.sg:443 -tls1_3
3
Add optional security headers (Referrer-Policy, Permissions-Policy)
uob.com.sg has most security headers configured. Missing: Referrer-Policy, Permissions-Policy. These are best-practice additions that reduce the attack surface for client-side vulnerabilities.
How to fix this
1
Add: Referrer-Policy: strict-origin-when-cross-origin
2
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
3
Verify with: curl -sI https://uob.com.sg | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
