Abstract: A set top box with a firewall is disclosed. The set top box uses two separate ports to communicate with two respective communications networks. The first port communicates with the first network to receive programming information and the second port communicates with the second network to receive information. A firewall, in communication with one of the ports, is capable of receiving and analyzing information from the port. The firewall helps to prevent harmful or unauthorized information from reaching other components of the set top box. The firewall can receive information before other components associated with the set top box and the firewall can include various different forms of filtering.

Abstract: Methods and devices are disclosed for discouraging unauthorized modifications to set top boxes and gateways. Resource information is received that describing the number of disk drives and/or the capacity of each disk drive. A processor communicates with a database that stores configuration information. The processor compares the resource information to the configuration information. When the resource information differs from the configuration information, then the processor detects unauthorized modifications to the set top box.
