Priority fixes for dtf.ru

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

1. Priority 1 · Harden

   TLS 1.3 negotiated

   Observed: The TLS connection negotiated TLSv1.2.

   Why it matters: TLS 1.3 removes legacy cipher suites and completes the handshake in fewer round trips, so it is both safer and faster for new connections.

   What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.

   On Cloudflare: Turn on TLS 1.3 under SSL/TLS > Edge Certificates.

   88% of Forums & Communities peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.

2. Priority 2 · Harden

   HSTS kept for at least a year

   Observed: The homepage response did not include a Strict-Transport-Security header.

   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.

   28% of Forums & Communities peers do this.

3. Priority 3 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 1 external script without async or defer.

   What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.

   41% of Forums & Communities peers do this.

4. Priority 4 · Harden

   Framing restricted

   Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.

   What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.

   On Cloudflare: Add the header with a response header transform rule.

   54% of Forums & Communities peers do this.
