- **Context Layer**: `CIFSContext` interface provides the main entry point
- **Resource Layer**: `SmbResource` interface represents SMB network resources  
- **Protocol Layers**: Separate SMB1 (`jcifs.internal.smb1/`) and SMB2/3 (`jcifs.internal.smb2/`) implementations
- **Authentication**: NTLM, Kerberos, SPNEGO unified subsystem
- **Network Layer**: Transport abstraction, NetBIOS name resolution, session management

## Ejemplo

Para un ejemplo simple, consideremos una estructura de archivos similar a la descrita en [Aplicaciones Más Grandes](../tutorial/bigger-applications.md){.internal-link target=_blank} y [Testing](../tutorial/testing.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

El archivo `main.py` tendría:

import org.mockito.Mock;
import org.mockito.junit.jupiter.MockitoExtension;

import jcifs.CIFSContext;
import jcifs.CIFSException;
import jcifs.SmbTree;
import jcifs.internal.CommonServerMessageBlockResponse;
import jcifs.internal.Request;

/**
 * Tests for SmbTreeInternal interface behavior via mocks.
 * Since this is an interface, we validate its public API contract
 * through interaction testing and generic type usage.

## Additional Features { #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.
