This plug-in helps setting up the various header instructions included in the HTTP protocol allowing for simple improvement of your website security.
This plug-in provides enabling of the following measures:
- HSTS (Strict-Transport-Security)
- CSP (Content-Security-Policy)
- Clickjacking mitigation (X-Frame-Options in main site)
- XSS protection (X-XSS-Protection)
- Disabling content sniffing (X-Content-Type-Options)
- Referrer policy
- Remove PHP version information from the HTTP header
- Remove WordPress version information from the header
securityheaders.com is a useful resource for evaluating your web site’s security.
As usual, make sure to understand the meaning of these options and to run full tests on your web site as some options may result in some features stop working.
- Upload the plugin files to the
/wp-content/plugins/http-securitydirectory, or install the plugin through the WordPress plugins screen directly.
- Activate the plugin through the “Plugins” screen in WordPress.
- Use the Settings -> HTTP Security screen to configure the plugin.
- How can I test the plug-in runs effectively?
Check the HTTP headers of your web site.
As a rookie regarding WordPress security I was pretty lost about HTTP Security headers until I found this pluging. So far it seems to be working great for me, even though I had to do some extra research to set up the Content Security Policy and Feature Policy thanks to these links (even if they are a bit old).
Maybe you could add them (or similar ressources) as references to create a CSP / feature policy for beginners like me ?
Thanks Carl for the great plugin and keep up the good work !
This plugin is easy to use. It is confined to a limited set of options to set the http headers. It seems that the most important ones have been chosen since testing my website after installing and setting the plugin yielded an A+ score on securityheaders.com. The only thing missings is cache-control; this would boost the performance of my website even more. Thanks to the maker of this plugin, I feel my website is safe and up-to-par with other safe websites like banking platforms.
Well im was going crazy all around the web searching for a way to protect my header i attemp to do almost everyting thats on the web to achieve this but on every scan i got this message: To improve the security of your site against some types of XSS (cross-site scripting) attacks, it is recommended that you add the following header to your site:
X-XSS-Protection: 1; mode=block
It is supported by IE (Internet Explorer) and Chrome. You can enable it by modifying your Apache settings or your .htaccess file, and adding the following line to it:
Header set X-XSS-Protection “1; mode=block”
i even attemp to follow these instructions but even adding that code this warning was still showing well i installed this plugin and i will try it to see if it help with what i need to do buy i want to thank the plugin developer for this amazing tool playing around with the h.access file is no game, i will like to get in touch with this developer to check if im using the right configuration…
If I could, I would give you 10 stars and dance at your wedding. You just saved me HOURS of work trying to figure out how to secure my site. After two hacks, I had enough and started securing it on my own. To slow and labor intensive (W3C school). Literally took me not even 5 minutes.
So, THANK YOU, THANK YOU, THANK YOU.
Really easy to set up, a lot of different options but still not hard to get into. The plugin does exactly what it is meant to do and does a great job at it! Adding a CSP to your site is only a matter of minutes with the plugin, but is a great addition to make your website secure against a lot of different attacks.
Thanks a lot for the plugin!
I’ve used this to implement http security headers on my WordPress site. Very easy to use and get good scores on evaluation sites. Content Security Policy seems to be an emerging technique to improve security. Its easy to implement using this plugin. Only one problem I’ve noticed: When I input data in the box for base-uri: and then check with Google CSP Evaluator it shoes all of the CSP values except for base-uri where it shows “base-uri;” regards of what’s entered in the plugin. Base-uri doesn’t fall back to the default-src directive so this shows up as an issue.
Still deserves 5 stars for its ease of use.
