==== Extra Properties

Gradle's enhanced objects, including projects, tasks, and source sets, can hold user-defined properties.

[.multi-language-text.lang-kotlin]
Add, read, and set extra properties via the owning object's `extra` property. Alternatively, you can access extra properties via Kotlin delegated properties using `by extra`.

# Advanced Security

## Additional Features

There are some extra features to handle security apart from the ones covered in the [Tutorial - User Guide: Security](../../tutorial/security/index.md){.internal-link target=_blank}.

!!! tip
    The next sections are **not necessarily "advanced"**.

    And it's possible that for your use case, the solution is in one of them.
