Abstract: Malicious software running in personal computers manipulates victims' bank accounts without their knowledge, performing transactions without the user's approval. The result is banking fraud, both against individual consumers and organizations. Using voice technologies, we demonstrate a prototype system to validate individual banking transactions without the need for out-of-band techniques such as telephone calls.

Abstract: A system and method for minimizing the likelihood of flaws in a firewall proxy is disclosed. Software wrappers are used to introduce fine-grained controls on the operation of existing proxy applications. These fine-grained controls create an extra measure of assurance that bugs (or malicious software) will not subvert the intent of the firewall. To provide even further assurance, the firewall system can be totally wrapped. A totally wrapped system includes a wrapper for the proxies plus a separate wrapper for everything else on the firewall system that can potentially interfere with the wrappers and the proxies. The software wrappers can also be integrated with an intrusion detection system. The fine-grained controls of the software wrapper enables it to be uniquely positioned to generate alerts based on an indication that a flaw exists in the proxy and that the proxy is misbehaving.

Abstract: A system and method for increasing the security of a data guard is disclosed. The data guard is based on a multi-part proxy that includes a first proxy agent that communicates with an inside computer network region, a second proxy agent that communicates with an outside computer network region, and a content-based filter application that reviews information that is passed between the first proxy agent and the second proxy agent. Both the first and second proxy agents can be based on existing firewall proxies. The proxy agents listen for protocol operations (e.g., IIOP requests or replies) and translate those protocol operations into protocol-independent data. The protocol independent data is then analyzed by a protocol-independent content-based filter. The behavior of the multi-part proxy can be further constrained through the use of software wrapper technology.
