Flexibility in Dealing with Possible Theft-of-Service Attempts
Service providers have the option of deciding what response to take when a DOCSIS configuration file fails its CMTS MIC check: mark that cable modem and allow the user online, reject the registration request and refuse to allow the user to come online until a valid DOCSIS configuration file is used, or lock the cable modem in a restricted QoS configuration until the modem remains offline for 24 hours. Locking malicious modems is the most effective deterrent against hackers, because it provides the maximum penalty and minimum reward for any user attempting a theft-of-service attack.
