# Security Foundation

Restrict a user’s access to particular features in your Mac app or daemon.

## Overview

Overview This document was previously titled Authorization Services Objective-C Reference, and it replaced the SFAuthorization chapter of the Security Objective-C API document. The other chapters of that document have been replaced by Security Interface. The Security Foundation framework contains a single class, SFAuthorization, which allows you to restrict a user’s access to particular features in your Mac app or daemon.
