For context, these are slides from a presentation I gave at EMWCon 2019. My laptop couldn't connect to the projector so I quickly copy and pasted to the wiki, so the slides might not be exactly perfect

What is it?

"Content Security Policy".

What does that actually mean?

Its a web browser feature that disables certain browser features that are commonly used in exploiting security vulnerabilities, particularly XSS (Cross-site scripting) type vulnerabilities.

In mediawiki this can be used to help lock down your MediaWiki, so even if you install an extension with a bug in it, your wiki would still be safe*

*For some types of vulnerabilities.
