Security checks
Each check inspects a different part of usa.gov's public security setup. Green means healthy, yellow needs attention, red is a problem.
Security Headers
Only 2/5 security headers present. Missing: CSP, Referrer-Policy, Permissions-Policy. This exposes the application to clickjacking, MIME-sniffing, and other client-side attacks.
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); SPF record present with soft-fail (~all). Issues: No DKIM records found for common selectors (may use non-standard selectors).
Known Breaches
No known breaches found in public disclosure databases.
HSTS Header
HSTS enabled: max-age=63072000. includeSubDomains present. Missing preload directive.
DNS Configuration
Strengths: 5 nameservers configured (dns5.gsa.gov., dns4.gsa.gov., dns3.gsa.gov., dns.gsa.gov.); DNSSEC enabled; Zone transfers properly restricted.
CVE Exposure
Detected technologies: Proxy/CDN. (Proxy/CDN detected but excluded from CVE matching — upstream infrastructure). All detected technologies are upstream CDN/proxy infrastructure. No application-level software versions exposed.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Certificate Hygiene
Strengths: Certificate valid, 63 days remaining; Issued by Let's Encrypt.
Recommended actions
2 items
Steps to improve usa.gov's security grade, ranked by impact.
1
Add missing security headers (CSP, Referrer-Policy, Permissions-Policy)
3 of 5 recommended security headers are missing on usa.gov: CSP, Referrer-Policy, Permissions-Policy. These headers protect against clickjacking, MIME-sniffing, and unauthorized browser feature access. Adding them is a server configuration change with no application code changes required.
Compliance impact
PCI-DSS 4.0Req 6.4.1
Security headers are required application controls
OWASPSecure Headers
Recommended baseline for web applications
How to fix this
1
Add Content-Security-Policy header (start with report-only to avoid breakage)
2
Add: Referrer-Policy: strict-origin-when-cross-origin
3
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
4
Verify with: curl -sI https://usa.gov | grep -iE 'content-security|x-frame|x-content|referrer|permissions'

2
Strengthen email authentication configuration
Email authentication is partially configured for usa.gov but has gaps. Actions needed: 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
Configure DKIM and publish public key in DNS
2
Verify with: nslookup -type=txt _dmarc.usa.gov
