Authorization and access protocols
As we saw in the previous section, authentication is responsible for validating a user's identity, confirming who they are and if it is really who they say they are. Authorization combines identity information with access information to allow the user to read, write, execute, or delete files and information based on their identity and privileges.
Network access control (NAC) devices are used to enforce the cooperate policies. NAC functions and capabilities will be discussed in the last section of this chapter, RADIUS, NAC, and other authentication features.
