  • Automatically detecting malicious computer network reconnaissance by updating state codes in a histogram
    Patent number: 7734776
    Abstract: A detection and response system that generates an Alert if unauthorized scanning is detected on a computer network that includes a look-up table to record state value corresponding to the sequence in which SYN, SYN/ACK and RST packets are observed. A set of algorithms executed on a processing engine adjusts the state value in response to observing the packets. When the state value reaches a predetermined value indicating that all three packets have been seen, the algorithm generates an Alert.
    Type: Grant
    Filed: February 29, 2008
    Date of Patent: June 8, 2010
    Assignee: International Business Machines Corporation
    Inventors: Alan D. Boulanger, Robert W. Danford, Kevin D. Himberger, Clark D. Jeffries, Raj K. Singh
