What is the main purpose of access control in security?

The main purpose of access control in security is to restrict entry to authorized personnel only. This system ensures that only individuals who have the proper credentials or permissions can enter specific areas or access certain information. By limiting access, organizations can protect sensitive locations, assets, and data from unauthorized access, theft, or harm.

This practice is essential in maintaining safety and security, as it helps to mitigate risks and prevent incidents that could arise from having unrestricted access. Effective access control measures often include mechanisms such as ID badges, biometric scanners, and security checkpoints, all designed to ensure that only those who are approved can gain entry.

While facilitating quick evacuation and monitoring employee attendance may be important for overall operations and safety, they are not the primary focus of access control. Instead, access control is fundamentally about maintaining security and ensuring a controlled environment.
