# Internals

> How Infisical is built, how it secures your data, and how permissions are evaluated.

This section covers how Infisical works underneath: the components it's built from, the security properties it guarantees, and how permissions are evaluated.

> [card] [Architecture and security](https://infisical.com/docs/internals/architecture/components.md)
>
> The parts Infisical is built from, how Infisical Cloud is deployed, and the encryption and isolation model.

> [card] [Permissions](https://infisical.com/docs/internals/permissions/overview.md)
>
> How the permission system evaluates access, and the full list of what each action grants.

> [card] [Service tokens](https://infisical.com/docs/internals/service-tokens.md)
>
> How a service token is structured, and how to scope, store, and rotate one safely.

> [!NOTE]
>
> You don't need to read this section to use Infisical. It's worth reading if you operate an
> instance, or if you're answering security questions about how Infisical handles your data.
