Abstract
A communication network (10) provides communicative coupling between potentially large populations of Internet-of-Things (IoT) devices (12) and/or other types of communication devices (12) and one or more Application Servers (ASs) (14) that are affiliated with respective ones of the communication devices (12). One or more network functions (30, 58) in the communication network (10) are operative to determine that any given one of the communication devices (12) is compromised, or that multiple such devices (12) are compromised, and provide for management of such devices (12) within the network (10) as “compromised” devices (12). Aspects of compromised-device management include forcing re-registration of such devices (12), for quarantining them in one or more quarantine network slices (54), and recovering quarantined devices (12) after remediation of the compromise. Recovery operations include forcing re-registration of devices (12) being recovered, for migration back to their normal or regular network slice(s) (50).
