Cross-Origin-Resource-Policy Protect servers against certain cross-origin or cross-site embedding of the returned source. Ref: https://developer.mozilla.org/en-US/docs/Web/HTTP/Cross-Origin_Resource_Policy_(CORP)
(*) NEL Enables web applications to declare a reporting policy to report errors. Ref: https://scotthelme.co.uk/network-error-logging-deep-dive/
(*) Permissions-Policy Previously called "Feature-Policy", allow and deny the use of browser features. Ref: https://scotthelme.co.uk/goodbye-feature-policy-and-hello-permissions-policy/
Referrer-Policy Controls how much referrer information should be included with requests. Ref: https://scotthelme.co.uk/a-new-security-header-referrer-policy/

[3. Fingerprint HTTP Response Headers]
These headers can leak information about software, versions, hostnames or IP addresses: X-FB-Debug [facebook.com Platform] Value: 'Mc5EeqU5XiZhQ3CR+zMc/AMdqsopEWF6PIrawTtrXYovR4a/LVE24IEQdSh1yJnBq2BJUeURR+haaoW+mo3nZA==' [4. Deprecated HTTP Response Headers/Protocols and Insecure Values]
The following headers/protocols are deprecated or their values may be considered unsafe: Content-Security-Policy (Deprecated Directives) Avoid using deprecated directives: 'report-uri', 'block-all-mixed-content' Ref: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy
Content-Security-Policy (Insecure Schemes) Do not allow insecure, unencrypted schemes: 'http:' Ref: https://www.cloudflare.com/learning/ssl/why-is-http-not-secure/
Ref: https://http.dev/wss
Content-Security-Policy (Too Permissive Sources) Limit these permissive origins: 'blob:', 'data:' Ref: https://content-security-policy.com/
Content-Security-Policy (Unsafe Values) 'unsafe-inline' and 'unsafe-eval' negate most of the security benefits provided by this header. Ref: https://csper.io/blog/no-more-unsafe-inline
Ref: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval
Pragma (Deprecated Header) This header is deprecated. Ref: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Pragma
Report-To (Deprecated Header) This header is deprecated. Use instead "Reporting-Endpoints". Ref: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Report-To
Strict-Transport-Security (Recommended Values) Add 'includeSubDomains' and 'max-age' (with 31536000 -one year- as minimum). Ref: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Strict-Transport-Security
Ref: https://https.cio.gov/hsts/
Strict-Transport-Security (Required Values) 'preload' requires 'includeSubDomains' and 'max-age' (with 31536000 -one year- as minimum). Ref: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Strict-Transport-Security
Vary (Potentially Unsafe Header) The values of this header may expose others, facilitating attacks if user input is accepted. Ref: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Vary
Ref: https://www.yeswehack.com/fr/learn-bug-bounty/http-header-exploitation
X-XSS-Protection (Deprecated Header) This header is deprecated in the three major web browsers. Instead, use the "Content-Security-Policy" header restrictively. Ref: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-XSS-Protection
[5. Empty HTTP Response Headers Values]
