Why would you want this?

Security, security, security.

This plugin helps you to detect and eliminate security errors in your Moodle such as: - Mixed content (https/http) after you switched to HTTPS. - Same origin (or specified origin) policy for scripts and media data.

What is this?

This plugin enables Custom Security Policy headers across the Moodle website. Examples: - Report/enforce SSL origin for links, images etc. - Report/enforce same-origin for links, images etc.

How does it work?

Site admin configures CSP headers: Content-Security-Policy or Content-Security-Policy-Report-Only in the plugin settings. Header Content-Security-Policy-Report-Only is for recording CSP violations in Moodle and reviewing them later from the plugin's report page. Enabling of Content-Security-Policy blocks browser from showing site resources that violate defined rules.

Installation

Checkout or download the plugin source code into folder local\csp of your Moodle installation.

git clone git@github.com:catalyst/moodle-local_csp.git local\csp

or

wget https://github.com/catalyst/moodle-local_csp/archive/master.zip
mkdir -p local/csp
unzip master.zip -d local/csp

Then go to your Moodle admin interface and complete installation and configuration. Example policy 'default-src https:;' will be reporting or enforcing the links to be HTTPS-only. Please note, the whole moodle website should be accessible via HTTPS for this to work. For more examples of other CSP directives please read here.
