US Patent:

7873350, Jan 18, 2011

Filed:

May 10, 2004

Appl. No.:

10/842131

Inventors:

Patrick Drew McDaniel - Chatham NJ, US
Martin Joel Strauss - Summit NJ, US

Assignee:

AT&T Intellectual Property II, L.P. - Reno NV

International Classification:

H04M 1/66

US Classification:

455411, 455410, 37911201, 37911414

Abstract:

The present invention is a system and method for establishing a secure connection using a public a wireless telephone network. The method utilizes a proxy base station and establishes an encrypted session over the public wireless network between a wireless handset and the proxy base station. The proxy base station further establishes a connection with second communication station such as a landline phone. The proxy base station determines a most secure channel between the base station and the second communication station by consulting a database of channels and associated measures of security.

Abstract:

A method and system for determining and enforcing security policy in a communication session are provided in distributed systems. Policy encompasses the provisioning, authorization, and access control within the protected environment. Hence, all communication security requirements are explicitly stated through policy. A policy instantiation is constructed at run-time through policy determination. Conditional, abstract, and discretionary policies stated by communication participants are reconciled to arrive at an instantiation. The resulting instantiation is a concrete specification of the mechanisms, configurations, and access control model to be implemented by the session. The semantics of an instantiation are achieved through policy enforcement. The policy enforcement architecture implements session policies through the composition and configuration of security mechanisms using a novel event-bus architecture. Policy is enforced through the observation of and reaction to relevant events. The method and system of the invention diverges from past subscription-based event architectures by introducing additional infrastructure allowing significant implementation flexibility, robustness, and efficiency.

Abstract:

A reverse firewall for removing undesirable traffic from a computing network, such as a virtual private network (VPN), is disclosed. The reverse firewall uses firewall rules that may be determined and maintained within the enterprise network to control communication sent between computers in the computing network. The reverse firewall rules may be used to identify the communications between computers in the network that are undesirable and/or intrusive. For example, a computer in a network that is infected with a worm or that is surreptitiously hosting a denial-of-service attack may be identified by the reverse firewall and quarantined. The reverse firewall may be implemented in hardware and/or software.
