There have been many attempts to make the Web a more secure place, or at least make it harder to attack web applications. One of them is CSP, Content Security Policy. In my talk, I will cover history of CSP, how it evolves from its original version, and what features will be available in the near future.
One of the challenges in deploying CSP is to understand what versions and directives are supported by different web browsers. In this presentation, I will share current CSP compatibility matrix for major web browsers to provide better understanding of CSP support. I will also demonstrate a framework that I developed to make it easy for anyone to run the same CSP feature set of tests to inspect the results as well as to add new feature check.
In the last part of the presentation, I will show the usage of CSP by Alexa top web sites and how good their CSP policies are. I will also explain common CSP mistakes and strategies to fix them. Last but not least, I will demonstrate various tools, frameworks and libraries which would be useful to improve CSP policies.
