# Content Security Policy (System) {#system-csp}

<!-- TODO: no Markdown rendering for "versionchanged" -->

This module has been moved from Admin tools to System
see Feature: #107628 - Improved backend module naming and structure.

[Content Security Policy](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/ContentSecurityPolicy/Index.html#content-security-policy) 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/m/typo3/reference-coreapi/main/en-us/ApiOverview/ContentSecurityPolicy/Index.html#content-security-policy-reporting). It is always available
but can only be [accessed via the backend](https://docs.typo3.org/permalink/t3start:admin-tools-access@main),
not the Install Tool.
