WEP (Wired Equivalent Privacy) is a deprecated wireless encryption protocol that scrambles data in transit but does not evaluate or filter devices based on their hardware addresses.

MAC filtering works by maintaining an allowlist of approved device hardware addresses on the wireless access point, which checks each connecting client's MAC address before granting network access. Since the question explicitly requires a method based on hardware address, MAC filtering is the direct technical answer - it ties access control to the physical identifier of the network interface card. No other listed option operates based on hardware address at all.

RAS (Remote Access Service) is a Microsoft dial-up and VPN connectivity service for remote users and has no function related to hardware address-based wireless access control.

SSID is simply the broadcast name of a wireless network; hiding or changing it provides minimal obscurity but does not enforce any hardware address-based access restriction.
