FAQ
- How to only report the CSP violations during a test phase?
You just have to check the box Only report CSP violations and the violations will be logged in the Jahia log files.
- How to generate the nonce value?
In your custom module, you have to set the value of the attribute nonce to the value of the Jahia property contentSecurityPolicy.nonce.placeHolder.
The value of your CSP, at the site level, has to contain the string nonce-.
Then for each page rendering, a random value will be generated and:
- will update the CSP for the page
- will replace in the HTML code the static value of the nonce
This way, a potential hacker should not be able to bypass this security.
