摘要： A method for defending against MAC table overflow attacks comprises a plurality of operations. An operation is performed for determining whether each one of a plurality of MAC addresses within a MAC table has one-way traffic or two-way traffic corresponding thereto. Thereafter, operations are performed for designating each MAC address having two-way traffic corresponding thereto as a first category of MAC address and for designating each MAC address having one-way traffic corresponding thereto as a second category of MAC address. In response to the number of the MAC addresses designated as the second category of MAC address exceeding a prescribed threshold value, an operation is performed for causing a timeout value of at least a portion of the MAC addresses designated as the second category of MAC address to be less than a timeout value of the MAC addresses designated as the first category of MAC address.

摘要： Mechanism for identifying malicious content, DoS attacks, and illegal IPTV services. By monitoring the characteristics of various control messages being transmitted within a network that services Internet protocol television (IPTV) content to identify suspicious behavior (e.g., such as that associated with malicious content, denial of service (DoS) attacks, IPTV service stealing, etc.). In addition to monitoring control messages within such a network, deep packet inspection (DPI) may be performed for individual packets within an IPTV stream to identify malicious content therein (e.g., worms, viruses, etc. actually within the IPTV stream itself). By monitoring control messages and/or actual IPTV content within a network (e.g., vs. at the perimeter of a network only), protection against both outside and inside attacks can be effectuated. This network level basis of operation effectively guards against promulgation of malicious content to other devices within the network.

摘要： Malicious sources within networks are identified using bait traffic, including mobile IP messages, transmitted between a collaborating network device and a collaborating mobile client that has a fixed connection to the network. The bait traffic entices a malicious source to transmit malicious packets towards the collaborating mobile client and/or the network device. Upon receiving a malicious packet, the collaborating mobile client or the network device is able to identify the source of the packet as a malicious source and report the presence of the malicious source within the network.
