Content Security Policies

Last updated : Nov 07, 2016
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

Assess ?

We are finding Content Security Policies to be a helpful addition to our security toolkit when dealing with websites that pull assets from mixed contexts. The policy defines a set of rules about where assets can come from (and whether to allow inline script tags). The browser then refuses to load or execute JavaScript, CSS or images that violate those rules. When used in conjunction with good practices, such as output encoding, it provides good mitigation for XSS attacks. Interestingly, the optional endpoint for posting JSON reports of violations is how Twitter discovered that ISPs were injecting HTML or JavaScript into their pages.
