Priority fixes for correio24horas.com.br

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Harden

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 180 days, below the one-year benchmark.

   Why it matters: HSTS tells browsers to use HTTPS for your host on every later visit, which removes the window where a first HTTP request can be intercepted.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   On Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.

   35% of News & Media peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Harden

   Content Security Policy present

   Observed: The homepage response did not include a Content-Security-Policy header.

   What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.

3. Priority 3 · Harden

   security.txt published

   Observed: No valid /.well-known/security.txt with a Contact field was returned.

   What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.

   On Cloudflare: Cloudflare Security Center can serve a security.txt file for the zone.

   6.2% of News & Media peers do this.

4. Priority 4 · Harden

   DNSSEC signed

   Observed: No DS record was found for correio24horas.com.br at its parent zone, so its DNS answers are not DNSSEC-signed.

   What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.

   On Cloudflare: Enable DNSSEC in DNS > Settings and add the DS record at the registrar.

   6.1% of News & Media peers do this.
