  • Patent number: 8931099
    Abstract: Computer system, method and program product for identifying a malicious intrusion. A first number of different destination IP addresses, a second number of different destination ports and a third number of different signatures of messages, are identified from a source IP address during a predetermined period. A determination is made that in one or more other such predetermined periods the source IP address sent messages having the first number of different destination IP addresses, the second number of different destination ports and the third number of different signatures. Based on the determination that in the one or more other such predetermined periods the source IP address sent messages having the first number of different destination IP addresses, the second number of different destination ports and the third number of different signatures, a determination is made that the messages are characteristic of a malicious intrusion.

  • Publication number: 20140048111
    Abstract: This invention relates to a method and system for producing electrical current based on a temperature differential. The system comprises of at least one unit having a plurality of chips sandwiched between a higher temperature layer on one side and a lower temperature layer on an opposite side. Chips are preferably thermoelectric solid state chips that produce an electric current when there is a temperature differential created across the chips. There are a plurality of chips in each unit and the chips within each unit are electrically connected to one another in series. Preferably, there are a plurality of units.

  • Patent number: 8127356
    Abstract: A computer system and program product for automatically determining if a packet is a new, exploit candidate. First program instructions determine if the packet is a known exploit or portion thereof. Second program instructions determine if the packet is network broadcast traffic presumed to be harmless. Third program instructions determine if the packet is network administration traffic. If the packet is a known exploit or portion thereof, network broadcast traffic, or network administration traffic, the packet is not considered a new, exploit candidate. If the packet is not a known exploit or portion thereof, network broadcast traffic, or network administration traffic, the packet is an exploit candidate. Alternately, the first program instructions determine if the packet is a known exploit or portion thereof. The second program instructions determine if the packet is network broadcast traffic presumed to be harmless.

  • Patent number: 7707633
    Abstract: A method of progressive response for invoking and suspending blocking measures that defend against network anomalies such as malicious network traffic so that false positives and false negatives are minimized. When an anomaly is detected, the detector notifies protective equipment such as a firewall or a router to invoke a blocking measure. The blocking measure is maintained for an initial duration, after which it is suspended while another test for the anomaly is made. If the anomaly is no longer evident, the method returns to the state of readiness. Otherwise, a loop is executed to re-apply the blocking measure for a specified duration, then suspend the blocking measure and test again for the anomaly. If the anomaly is detected, the blocking measure is re-applied, and its duration is adapted. If the anomaly is no longer detected, the method returns to the state of readiness.

  • Publication number: 20030013087
    Abstract: The invention features novel mutations in the FREAC3 gene. Our discovery provides methods for early diagnosis of glaucoma, other disorders of the eye, and heart defects. Also provided are cells having at least one deficient FREAC3 gene. Such cells may be used to detect therapeutic compounds that mimic FREAC3, are agonists of FREAC3, or otherwise modulate the level of FREAC3 biological activity.
