Access control is a security measure designed to regulate who can enter or exit a specific facility or area. This concept encompasses a range of practices and technologies that ensure only authorized individuals can gain entry, thereby enhancing safety and security. The focus is on maintaining a secure environment by implementing protocols and systems that identify, authenticate, and authorize individuals based on predetermined criteria.

By controlling entry and exit points, access control helps prevent unauthorized access, reduces the risk of theft or vandalism, and enables a swift response in emergencies. It is a fundamental aspect of security in both physical locations, such as buildings or restricted areas, and digital environments, where it aims to safeguard information.

In contrast, options that suggest allowing anyone to enter a facility do not align with the principles of access control, as this would impede security measures. Similarly, focusing on the internet or only limiting access to unauthorized personnel does not capture the comprehensive nature of access control in physical spaces. Thus, the focus on regulating who is permitted entry aligns perfectly with the core purpose of access control.
