The function of admission control is to guarantee that network resources are only accessed by authorized devices which are who claim to be. Thus, it contains two aspects, one is authentication of the stations and the other is authorization
to access the resources. Normally both functions are combined in a single access protocol. Different attacks against admission control are the following: identity usurpation, replay attacks, man-in-the-middle attacks, hijack of MAC addresses, session hijacking, masquerading, malicious device and message interception. Availability refers to the prevention from accessing and using the network by some unauthorized party. Attacks to availability are called Denial of Service (DoS) attacks. The security requirement demands that the specificationmust be robust against these attacks as well as to any other possible attack.
