Discussion

Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity on the network. In addition to the reauthentication requirements associated with session locks, organizations may require reauthentication of devices, including (but not limited to), the following other situations: (i) When authenticators change; (ii) When roles change; (iii) When security categories of information systems change; (iv) After a fixed period of time; or (v) Periodically. This requirement only applies to components where this is specific to the function of the device or has the concept of device authentication.
