Missing Headers
Content-Security-PolicyContent Security Policy is an effective measure to protect your site from XSS attacks. By whitelisting sources of approved content, you can prevent the browser from loading malicious assets.
X-Frame-OptionsX-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. Recommended value "X-Frame-Options: SAMEORIGIN".
Referrer-PolicyReferrer 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.
Feature-PolicyFeature Policy is a new header that allows a site to control which features and APIs can be used in the browser.
Upcoming Headers
Expect-CTExpect-CT allows a site to determine if they are ready for the upcoming Chrome requirements and/or enforce their CT policy.
Additional Information
ServerServer value has been changed. Typically you will see values like "Microsoft-IIS/8.0" or "nginx 1.7.2".
X-Powered-ByX-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-Content-Type-OptionsX-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".
Strict-Transport-SecurityHTTP 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.
