This is a great article. I’m curious how these recommendations for CSP work in tandem with trusted types, which Philippe wrote about previously: Securing SPAs with Trusted Types.

@PhilippeDeRyck would you be able to follow-up on that? Thanks!

Trusted Types targets a specific way to go from text to executable code. CSP covers a similar path, but in a less reliable way. However, CSP covers a lot more ways to load script code (e.g., remote files), so it is more extensive.

In a nutshell, I would see both mechanisms as separate defenses, but use them together as a robust defense strategy against XSS.


That’s great. Thank you for the explanation.
