Access control is a critical aspect of security management that focuses on regulating who or what can enter or exit a defined area. The correct definition emphasizes the balance between allowing the movement of authorized individuals and materials while actively working to detect, delay, and prevent unauthorized access.

This definition highlights several key functions of an effective access control system:

1. **Authorization**: It clearly delineates who is permitted to enter specific areas, which is fundamental for maintaining security and safety.

2. **Detection**: The system is designed to recognize potential breaches, which enables a swift response to threats.

3. **Delay**: Implementing measures that can slow down unauthorized attempts to gain access provides valuable time for security personnel to respond.

4. **Prevention**: Ultimately, the goal is to prevent unauthorized access altogether to protect sensitive areas or assets.

The other options diverge from this comprehensive approach. They either focus narrowly on aspects of access (like the freedom of movement) or introduce an arbitrary element of control that lacks effective security measures. The focus on detection and proactive prevention in the correct definition underscores the essence of effective access control in maintaining a secure environment.
