Describe the term "access control" in security management.

Access control in security management refers to the methods and processes implemented to restrict entry to designated areas, resources, or information to only those individuals who are authorized. This concept is critical in maintaining the safety and integrity of secure environments, whether in physical locations or digital systems. It ensures that only individuals with the appropriate clearance or credentials can enter specific areas or access sensitive information, thereby preventing unauthorized access and potential security breaches.

Implementing effective access control measures may involve the use of identification badges, biometric scanners, access logs, or security personnel monitoring entry points. This not only protects physical spaces but also helps safeguard confidential data and proprietary information from threats.

The other options pertain to distinct fields, such as employee scheduling, customer service techniques, and performance evaluations, which are not directly related to the core principles of security management regarding access control. Therefore, focusing on restricting entry to authorized personnel is fundamental to establishing a secure environment.
