A subscriber access control system (SACS) [Fig 1, 100] configures a network device connected to cable network to affect the behavior of that device. The SACS comprises a rules engine [Fig 1, 125] and a datastore [Fig 1, 130] that stores the current state of subscribers known to the SACS and historical request information. When the SACS receives a request to quarantine a device , it assigns attributes to a subscriber record accessed by a DHCP server to affect the configuration and behavior of that device. The actual behavior of the quarantined device is determined by the presence of the attribute and th e value of the attribute.
