# Module "Content Security Policy" (System)

[Content Security Policy](https://docs.typo3.org/permalink/t3coreapi:content-security-policy@main) declarations
can be applied to a TYPO3 website in frontend and backend scope with a dedicated
API.

This module handles
[Reporting of violations of the Content Security
Policy](https://docs.typo3.org/permalink/t3coreapi:content-security-policy-reporting@main). It is always available
but can only be [accessed via the backend](https://docs.typo3.org/m/typo3/tutorial-getting-started/main/en-us/Concepts/Backend/SystemMaintainerArea/Index.html#admin-tools-access),
not the Install Tool.
