The curl above is the fastest check; all four lines should come back. In a browser, DevTools, Network tab, click the document request, read Response Headers. For a letter grade, securityheaders.com scores you against a known rubric. One quirk: these four alone land a B, and you reach A only once you add Content-Security-Policy. - Source: dev.to / 3 months ago
Remediation: Configure your web server to suppress or mask the Server header. Add security headers like Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
