Recommended actions
1 item
Steps to improve letsdothis.com's security grade, ranked by impact.
1
Enable HSTS (HTTP Strict Transport Security)
The HSTS header is missing on letsdothis.com. Without it, connections can be downgraded from HTTPS to HTTP via man-in-the-middle attacks. This is a straightforward server configuration change.
Compliance impact
PCI-DSS 4.0Req 6.4.1
Required application security controls
NIST 800-53SC-8
Transmission confidentiality and integrity
How to fix this
1
Add header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
2
Verify all subdomains support HTTPS before adding includeSubDomains
3
Test with: curl -sI https://letsdothis.com | grep -i strict
4
Submit to hstspreload.org after confirming the header is correct
