Redirect All Traffic to HTTPS
Permanently redirects every plain HTTP request to the HTTPS version of the same URL, for sites whose host does not do it already.

Security snippets for WordPress
Snippets that harden WordPress: turn off XML-RPC, hide the version number, stop user enumeration, add security headers and block risky uploads. Small, reviewable changes for site owners who want fewer attack points without a heavy security plugin.
Reject Requests for Unknown Host Names
Returns an error for requests whose Host header is not your site's domain, which blocks host header injection tricks (such as poisoned password reset links) and junk traffic aimed at your server's IP.
