What to fix

  1. Add Strict-Transport-Security
    Header: Strict-Transport-Security: max-age=31536000; includeSubDomains
  2. Add a Content-Security-Policy
    Limits which scripts can run, and is the main defense against XSS. Start with Content-Security-Policy-Report-Only to test.
  3. Add X-Content-Type-Options
    Header: X-Content-Type-Options: nosniff
  4. Prevent clickjacking
    Header: X-Frame-Options: DENY (or a CSP frame-ancestors directive).
  5. Add a Referrer-Policy
    Header: Referrer-Policy: strict-origin-when-cross-origin
