GD Security Headers

By Milan Petrovic

Description

Configure various security-related HTTP headers, including Content Security Policy, Feature Policy, Referrer Policy and more. For CSP and XSS plugin supports report logging with 2 additional database tables to store reports from browsers.

The plugin has support for following HTTP headers:

  • Content Security Policy (CSP) – with reporting
  • XSS Protection (XXP) – with reporting
  • Feature Policy
  • Content Type – No Sniff Policy
  • Strict Transport Security
  • Referrer Policy
  • Frame Options

For CSP, the plugin allows you to set rules for all currently supported directives, additional settings including setting the policy in Report or Live mode. The plugin also includes special extensions that can automatically fill CSP rules for popular Google services you might be using on your website (Fonts, Maps, Adsense, Analytics and more) and other populare services (Gravatar, Vimeo and more).

And, for Feature Policy, the plugin allows you to set rules for all currently supported features.

The plugin can add all the generated headers into HTACCESS file (for Apache web servers), and they will be applied to all files, not just WordPress generated content. If your website is not using Apache (or .HTACCESS), all rules are generated with each page request and will work with any server type.

And, if you don’t use Apache web server, plugin has a panel where it displays generated headers for most popular servers: Apache, Nginx and IIS, and you can copy generated headers to add to server configuration files.

For someone who is not a developer, GD Security Headers (GPSH) plugin is truly a gift to WP users. It turns "Rocket Science" into just "Science 101"; still needs a bit of knowledge of what you're doing but this makes it so much easier to tweak security headers. Particularly, that option to only generate reports first for "Content-Security-Policy" before going live is how great plugins should be designed. Also love the fact that if enabled, the GPSH can write directly to the .htaccess file, and if a user prefers otherwise, they can also choose to disable that option to manually add by way of the 'Generated Headers' button. Now, I do have some feedbacks though but please bear in mind again I'm no developer. As such, the things I write might make some of the senior WP users chuckle but I'm just sharing what I think I understand. 1. GPSH writes to the .htaccess file that resides in the same folder where all WP files are kept, meaning if the WP installation is kept inside another folder i.e. /public_html/WP/, the /public_html/WP/.htaccess file will be written to instead of /public_html/.htaccess. Don't know if it changes anything but just thought I should share that some folks do move their WP installation to another folder. 2. Even though 'Add: X-XSS-Protection' has been enabled, a check on Mozilla Observatory came back with the error: "X-XSS-Protection header cannot be recognized". However, just want to add that it did come out ok when checked on Security Headers. 3. According to Security Headers, there also seems to be a new header called "Feature-Policy". Is this something that's already in GPSH? I can't find it. Also, First! 🙂
