Priority fixes for ndr.de
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 1 hours, short of the 30-day benchmark.
Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
60% of News & Media peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · 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.
42% of News & Media peers do this.
Priority 3 · 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.
29% of News & Media peers do this.

Priority 4 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for ndr.de, so any public certificate authority may issue for it.
What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.
13% of News & Media peers do this.
