Design Document for Understanding macOS Security Features

  1. Title and Overview

Project Name: macOS Security Feature Exploration Objective: Learn and implement macOS security features like sandboxing, keychains, and secure storage APIs.

  1. Goals and Non-Goals

Goals: • Understand and use macOS security APIs. • Implement secure app storage and sandboxing.

Non-Goals: • Creating a custom security framework.

  1. Design Overview • Input: Application requiring secure storage or restricted access. • Output: Secure macOS application. • Architecture: • Sandboxing: Restrict application access to the system. • Secure Storage: Use Keychain APIs for storing sensitive data.

  2. System Design
    1. Enable Sandboxing: • Modify the app’s entitlements to enable sandboxing.
    2. Use Secure APIs: • Implement Keychain storage for sensitive information.
  3. Testing Strategy • Validate sandboxing restrictions. • Test data encryption and access controls.
