Abstract
A subscriber access control system (SACS) configures a network device connected to cable network to affect the behavior of that device. The SACS comprises a rules engine and a datastore 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 the value of the attribute.
