  • Patent number: 9288218
    Abstract: To secure an accessible computer system, the computer system is monitored for connection transactions. An access requestor is denied access to the computer system when the access requestor initiates a number of connection transactions that exceed a configurable threshold number during a first configurable period of time. The monitoring may include detecting connection transactions initiated by the access requestor, counting the number of connection transactions initiated by the access requestor during the first configurable period of time, and comparing the number of connection transactions initiated by the access requestor during the first configurable period of time to the configurable threshold number.

  • Patent number: 8850046
    Abstract: To secure an access provider, communications to/from the access provider are monitored for a partially-completed connection transaction. Detected partially-completed connection transactions are terminated when they remain in existence for a period of time that exceeds a threshold period of time. The monitoring may include detecting partially-completed connection transactions initiated by an access requestor, measuring the period of time that a partially-completed connection transaction remains in existence, comparing the period of time with the threshold period of time, and resetting a communication port located on the access provider.
