Gang Xu - Piscataway NJ, US

Assignee:

AT&T Intellectual Property I, L.P. - Atlanta GA

International Classification:

G01C 21/34
G08G 1/01

US Classification:

701118, 701410, 4554565

Abstract:

A cellular-based live traffic service that does not require pre-deployment of infrastructure or GPS-enabled devices uses signals provided by cellular devices to determine course resolution localization and tracking information of the cellular devices. Specialized statistical analysis is performed on the course resolution data to infer the fine resolution positions of the cellular devices. In an example embodiment, the localization and tracking information is provided on a map, or the like, to show relative position and/or trajectory of cellular devices.

International Classification:

G06F 21/00

US Classification:

726 22, 713188, 726 24

Abstract:

An edge monitoring approach can be utilized to detect an attack which includes a plurality of relatively low bandwidth attacks, which are aggregated at a victim sub-network. The aggregated low bandwidth attacks can generate a relatively high bandwidth attack including un-solicited data traffic directed to the victim' so that the aggregated attack becomes more detectable at an edge monitor circuit located proximate to the victim. Related systems, devices, and computer program products are also disclosed.

US Classification:

726 12

Abstract:

Example methods and apparatus to enhance security in residential networks and residential gateways are disclosed. A disclosed example apparatus includes a transceiver to receive an Internet protocol (IP) packet, a first packet processing module associated with a protected IP address, the first packet processing module to be communicatively coupled to a first network device, a second packet processing module associated with a public IP address, the second packet processing module to be communicatively coupled to a second network device, and a packet diverter to route the received IP packet to the first packet processing module when the IP packet contains the protected IP address and to route the IP packet to the second packet processing module when the IP packet does not contain the protected IP address.

International Classification:

H04L 12/26

US Classification:

370238

Abstract:

A method provides for the dynamic traffic prioritization in a communication network. The method electronically monitors traffic in a communication network and determines when traffic exceeds configured thresholds on the links of the communication network. Thus, the method determines a link which is potentially about to be congested in the communication network. The method categorizes the traffic on this link by an end system attached to one end of the potentially congested link into a plurality of priority categories using application layer parameters. Using a re-direct capability of the end system, the method re-directs at least one of the pluralities of priority categories of traffic to an alternate Internet Protocol address. The method uses preconfigured Quality of Service mechanisms on the provider edge router attached to the other end of the potentially congested link to guarantee a predetermined amount of bandwidth capacity of the link to traffic destined to the alternate Internet Protocol address.

Assignee:

AT&T INTELLECTUAL PROPERTY I, L.P. - Reno NV

International Classification:

G06F 21/00

US Classification:

726 24

Abstract:

Devices, systems, and methods are disclosed which leverage an agent that resides in a mobile communication device to detect Proximity based Mobile Malware Propagation (PMMP). The agent injects one or several trigger network connections in the candidate connection list. These connections appear as legitimate networks and devices. However, the triggers connect to an agent server on a service provider's network. Essentially, the method is based on the assumption that malware lacks the intelligence to differentiate the trigger network connection from a normal one. Therefore, by attempting to connect through the trigger network connection, the malware reveals itself. The system helps collect the malware signature within a short period of time after the malware outbreak in local areas, and such attacks typically bypass network based security inspection in the network.

International Classification:

G06F 21/00

US Classification:

726 24

Abstract:

Devices, systems, and methods are disclosed which utilize lightweight agents on a mobile device to detect message-based attacks. In exemplary configurations, the lightweight agents are included as contacts on the mobile device addressed to an agent server on a network. A malware onboard the mobile device, intending to propagate, unknowingly addresses the lightweight agents, sending messages to the agent server. The agent server analyzes the messages received from the mobile device of the deployed lightweight agents. The agent server then generates attack signatures for the malware. Using malware propagation models, the system estimates how many active mobile devices are infected as well as the total number of infected mobile devices in the network. By understanding the malware propagation, the service provider can decide how to deploy a mitigation plan on crucial locations. In further configurations, the mechanism may be used to detect message and email attacks on other devices.
