    摘要： A system and method for verifying and/or geolocating network nodes in attenuated environments for cyber and network security applications are disclosed. The system involves an origination network node, a destination network node, and at least one router network node. The origination network node is configured for transmitting a data packet to the destination network node through at least one router network node. The data packet contains a security signature portion, a routing data portion, and a payload data portion. The security signature portion comprises a listing of at least one network node that the data packet travelled through from the origination network node to the destination network node. In addition, the security signature portion comprises geolocation information, identifier information, and timing information for at least one network node in the listing.

    摘要： Methods and apparatus for use in identifying abnormal behavior in a control system. Operating events associated with a control system are received, and an actual behavior of the control system is determined based on the received operating events. The actual behavior is compared to expected behavior to determine whether the actual behavior differs from the expected behavior. The expected behavior includes a correlation between a plurality of operating events associated with the control system. The expected behavior is updated based on an indication of whether the actual behavior is abnormal from a user.

    摘要： A system for conveying priority associated with a communication conveyed among networks includes: (a) a first network originating the communication in packets; each respective packet including two segments; a first segment containing a portion of the communication in information payload bits in a first encoding scheme; a second segment containing overhead information relating to the packet in overhead bits in a second encoding scheme; a number of the overhead bits being configured to indicate the priority; and (b) a second network cooperating with the first network to alter encoding of the first segment of a selected packet-set to express the information payload bits in a third encoding scheme that is unreadable in the second network; the second network employing the priority-indicating bits to ascertain priority for handling the communication by the second network; the second network preempting lower priority resources to reserve resources for higher priority packet-sets.
