Dette innstikket **er ikkje testa med dei tre siste utgåvene av WordPress**. Det
kan henda det ikkje blir vedlikehalde lenger, og kan ha problem med nyare versjonar
av WordPress.

## Skildring

TLS is growing in complexity. Server Name Indication (SNI) now means HTTPS sites
may be on shared IP addresses, or otherwise restricted. For these servers it is 
handy to be able to set desired HTTP headers without access to the web servers configuration
or using .htaccess file.

This plug-in exposes controls for:

 * HSTS (Strict-Transport-Security)
 * HPKP (Public-Key-Pins)
 * Disabling content sniffing (X-Content-Type-Options)
 * XSS protection (X-XSS-Protection)
 * Clickjacking mitigation (X-Frame-Options in main site)
 * Expect-CT

HSTS is used to ensure that future connections to a website always use TLS, and 
disallowing bypass of certificate warnings for the site.

HPKP is used if you don’t want to rely solely on the Certificate Authority trust
model for certificate issuance.

Disabling content sniffing is mostly of interest for sites that allow users to upload
files of specific types, but that browsers might be silly enough to interpret of
some other type, thus allowing unexpected attacks.

XSS protection re-enables XSS protection for the site, if the user has disabled 
it previously, and sets the «block» option so that attacks are not silently ignored.

Clickjacking protection is usually only relevant when someone is logged in but users
requested it, presumably they have rich content outside of WordPress authentication
they wish to protect.

Expect-CT is used to ensure Certificate Transparency is configured correctly.

## Installasjon

 1. Upload «security_headers.php» to the «/wp-content/plugins/» directory.
 2. Activate the plugin through the «Plugins» menu in WordPress.

Just a quick warning: if you enable this plugin, the Tawk.to widget is no longer
displayed in Chrome, Firefox and Safari. Edge is not affected (yet?).

Works really well! Tested with [link removed] For the future releases it would be
good to include Content-Security-Policy and the forthcoming Expect-CT options.
