Access control is a security technique/process that regulates who or what can view or use resources. At its core access control is a fundamental concept in security to minimize risk.
There are two major types of access control: physical and logical. Physical access control limits access to physical areas while a logical access control limits connection to networks, files, data, etc. Physical access control focuses on securing a facility with electronic control systems that utilize credentials, card readers, etc. to grant access. The logical system will control access through identity authentication, user authorization, biometrics, etc.
Both systems seek to help mitigate and limit risk for your business. Let’s look at the main types of access control.
