In the context of security, what does 'access control' refer to?

Access control refers to the systematic approach of managing and regulating who is permitted to enter or use specific facilities, resources, or areas within a security framework. This involves the implementation of policies, procedures, and technologies designed to ensure that only authorized individuals can gain access to sensitive or restricted locations, information, or assets.

By establishing access control measures—such as key cards, biometric systems, or security protocols—organizations can effectively protect their property, information, and people from unauthorized access, thereby significantly enhancing overall security. Recognizing the importance of access control is fundamental in maintaining a secure environment, as it not only safeguards against potential threats but also helps maintain order and accountability within the premises.
