Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement or distribution of malware. See Content Security Policy for more details.
This showcase is for testing CSP integration in PrimeFaces. Just step through the test cases and click at the appropriate button to check if everything is working as expected. If so, you should receive a PASS message.
