Access control is more of a problem for wired LANs than for wireless LANs. True or False?

• A. True
• B. False
• C. It depends on encryption
• D. Only for large networks

Answer: (B)

Access control is about ensuring that only authorized devices and users can connect to the network and access resources. On wired LANs, entry points are physical switch ports, so you can enforce controls like switch port security, 802.1X authentication with a RADIUS server, and network access control to grant access only after verification. While these controls exist and can be bypassed by someone with physical access, the attack surface is largely constrained to physical access points.

Wireless LANs, by contrast, broadcast signals through the air, so anyone within range can attempt to connect unless strong authentication and encryption are in place. This makes access control a central, ongoing challenge: you need robust authentication (such as 802.1X with enterprise credentials or strong PSKs), strong encryption (WPA2/WPA3), management of keys, and protection against rogue access points and other wireless-specific attack vectors. Because of this open-air characteristic, access control is typically more demanding for wireless networks.
