Additional Information
Server | This Server header seems to advertise the software being run on the server but you can remove or change this value. |
---|---|
X-Powered-By | X-Powered-By can usually be seen with values like "PHP/5.5.9-1ubuntu4.5" or "ASP.NET". Trying to minimise the amount of information you give out about your server is a good idea. This header should be removed or the value changed. |
X-XSS-Protection | X-XSS-Protection sets the configuration for the XSS Auditor built into older browsers. The recommended value was "X-XSS-Protection: 1; mode=block" but you should now look at Content Security Policy instead. |
X-Content-Type-Options | X-Content-Type-Options stops a browser from trying to MIME-sniff the content type and forces it to stick with the declared content-type. The only valid value for this header is "X-Content-Type-Options: nosniff". |
X-Frame-Options | X-Frame-Options tells the browser whether you want to allow your site to be framed or not. By preventing a browser from framing your site you can defend against attacks like clickjacking. |
Expect-CT | Expect-CT will soon be deprecated and can be removed. |
Referrer-Policy | Referrer Policy is a new header that allows a site to control how much information the browser includes with navigations away from a document and should be set by all sites. |
Permissions-Policy | Permissions Policy is a new header that allows a site to control which features and APIs can be used in the browser. |
Strict-Transport-Security | HTTP Strict Transport Security is an excellent feature to support on your site and strengthens your implementation of TLS by getting the User Agent to enforce the use of HTTPS. |
