    摘要: A system is disclosed for assuring the integrity of file segments. A first server has an associated file repository storing a plurality of files and transfers a file segment on an output upon request. A second server also has an associated file repository and receives and stores the file segment in the associated file repository. The second server identifies if there are additional segments of the same file in the associated file repository and processes the received file segment together with the additional identified file segments to identify the presence of malware. Finally, the second server transfers the received file segment on an output as a scanned file segment only if no malware is identified. A third server has an associated file repository and is configured to receive and store the scanned file segments in the associated file repository and to transfer a received scanned file segment to a client.

    摘要: A system for securely transferring information from an industrial control system network, including, within the secure domain, one or more remote terminal units coupled by a first network, one or more client computers coupled by a second network, and a send server coupled to the first and second networks. The send server acts as a proxy for communications between the client computers and the remote terminals and transmits first information from such communications on an output. The send server also transmits a poll request to a remote terminal unit via the first network and transmits second information received in response to the poll on the output. The system also includes, outside the secure domain, a receive server having an input coupled to the output of the send server via a one-way data link. The receive server receives and stores the first and second information provided via the input.

    摘要: A cross-domain system for transferring files from a client to a server. A first server in the first network domain receives and stores files from the client via the first network. The received files are processed based on predetermined instructions stored in an associated file. The processed received files are transmitted to a second server via a one-way data link. The second server in the second network domain receives and stores the processed received files. The received files are further processed based on predetermined instructions stored in an associated file. The further processed received files are transmitted to the server via the second network. The two associated files are stored in permanent memory with security policies which prevent the files from disrupting operation of the first and second servers, respectively. The security policies allow the associated files to be overwritten to update the processing performed by the associated server.

    摘要: A communications device for ensuring secure data transfer provided having an interface device for controlling data transfer, an integrated circuit coupled to the interface device and having a processor, a non-volatile memory for storing at least program code for the processor, a volatile memory, an input pin and an output pin; and an electrical conductor which electrically connects the input pin and the output pin. The electrical conductor passes through an external portion of the enclosure, e.g., a slot, which allows a user to easily sever the electrical conductor. In operation, a portion of the program code detects when the electrical conductor is severed and causes the program code in the non-volatile memory to be erased, data transfer via the interface device to be disabled, and power to the integrated circuit cut off to ensure that all information in volatile memory is erased.

    摘要: A method and system for testing a file (or packet) formed from a sequential series of information units, each information unit within a predetermined set of information units, e.g., each information unit may correspond to a character within the ASCII character set. An information unit-pair entropy density measurement is calculated for the received file using a probability matrix. The probability matrix tabulates the probabilities of occurrence for each possible sequential pair of information units of the predetermined set of information units. The computed information unit-pair entropy density measurement is compared with a threshold associated with an expected file type to determine whether the received file is of the expected file type or of an unexpected file type. The probability matrix may optionally be generated from the received file prior to calculating the density thereof. The probability matrix may optionally be predetermined based on the expected file type.

    摘要: A bilateral data transfer system comprising a first node, a second node, a first one-way link for unidirectional transfer of first data from the first node to the second node, and a second one-way link for unidirectional transfer of second data from the second node to the first node, wherein the unidirectional transfer of the first data across the first one-way link and the unidirectional transfer of the second data across the second one-way link are independently administered by the bilateral data transfer system. Under such bilateral data transfer system, each of the one-way data links may be subject to separately administered security restrictions and data filtering processes. Hence, it enables secure bilateral communications across different network security domains.
