Access control is concerned with determining the allowed activities of legitimate users mediating every attempt by a user to access a resource in the system. Repeated access attempts will be limited by locking out the user ID after not more than six attempts. Protect wireless access to the system by deploying strong authentication of users and devices along with strong encryption that can reduce susceptibility to threats by adversaries involving wireless technologies.

Media access control MAC is a sublayer of the data link layer DLL in the seven-layer OSI network reference model. TSA identification media and access control media are the property of TSA. MAC is responsible for the transmission of data packets to and from the network-interface card and to and from another remotely shared channel.
