That would be " Perimeter Security " making a physical location less tempting and less vulnerable as a target. ( It's in the Comptia A+ study , "Understanding Data & Security, pg. 501" Joe Lopez Jr.

You can enable MAC address (also know as Physical Address) filtering. MAC address filtering has two modes: 1. Allow access to listed MAC addresses 2. Deny access to listed MAC addresses.
Access control is a system which enables an authority to control access to areas and resources in a given physical facility or computer-based information system.

Ethernet addresses are 48 bits long - not 32 bits long like IP addresses. Different single network standards have different address lengths. Ethernet addresses are called MAC addresses for other reasons, Media Access Control.
Access control software refers to systems that manage and regulate entry to physical or virtual spaces, often using authentication mechanisms like passwords, biometrics, or access cards. While it's true that access control software enhances security by limiting unauthorized access, it's crucial to acknowledge potential drawbacks. Overreliance on such software can create a false sense of security, overlooking vulnerabilities like social engineering or insider threats. Additionally, excessive reliance on access control may impede user convenience and hinder productivity. Therefore, while access control software serves a purpose, it's imperative to adopt a holistic security approach that addresses diverse threats and balances security with usability.
