Content Security Policy Level 2

Last updated on : 2023-03-20

Note:

Content Security Policy Level 2 shows a browser compatibility score of 92. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

Use content security policy to mitigate cross-site scripting attacks by only allowing certain types of resources. CSP 2 adds hash-source and nonce-source to the list of supported directives, as well as five new directives.
