# Backend modules {#backend-modules-how-to}

TYPO3 CMS offers a number of ways to attach custom functionality to the
backend. They are described in this chapter.

**[Backend module API](https://docs.typo3.org/permalink/t3coreapi:backend-modules@12.4)**

See the API about classes and configuration for backend modules.

**[Backend module configuration examples](https://docs.typo3.org/permalink/t3coreapi:backend-modules-configuration-examples@12.4)**

Howto register custom modules provided by extensions.

**[Create a module with Extbase](https://docs.typo3.org/permalink/t3coreapi:backend-modules-extbase@12.4)**

Explains how to create a module with Extbase and Fluid. This is
the preferred method if extensive data modeling is involved.

**[Create a module with Core functionality](https://docs.typo3.org/permalink/t3coreapi:backend-modules-template-without-extbase@12.4)**

Explains how to create a module without Extbase. Fluid can still be
used, however there are some limitations. This is the preferred way
if no extensive data modelling is needed.

**[Security Considerations](https://docs.typo3.org/permalink/t3coreapi:backend-modules-security@12.4)**

Explores web application security considerations when
developing custom modules for the backend user interface.

**[Tutorials](https://docs.typo3.org/permalink/t3coreapi:backend-modules-tutorials@12.4)**
