Physical vs. Logical Access: Why the Separation?

Physical access control systems (PAC) and logical access control systems were developed independently to address different security needs.

• Physical access control systems were primarily designed to manage entry to buildings and physical spaces. These systems are heavily dependent on hardware components like locks, turnstiles and gates to prevent unauthorized access into an area. While early access tech consisted primarily of physical keys, modern PAC systems for large buildings usually rely on ID badges, keypads with PIN entry or a combination. Some systems also incorporate biometrics.
