Content Security Policy

Full Title or Meme

Content Security Policy is a mechanism designed to make applications more secure against common web vulnerabilities, particularly cross-site scripting. It is enabled by setting the Content-Security-Policy HTTP response header.

Context

• As a part of having a Trusted Identity in Cyberspace a series of Framework Profiles have been created to allow digital Entities to give users a statement about the policies that they support.

Problems

Cross-site scripting (XSS) attacks, for example, bypass the same origin policy by tricking a site into delivering malicious code along with the intended content. This is a huge problem, as browsers trust all of the code that shows up on a page as being legitimately part of that page’s security origin.
