  • Patent number: 10873467
    Abstract: This document discloses a method and system for just-in-time compression and optimization of raw unstructured in-line and in-transit data by identifying low entropy data blocks or duplicated information security information in raw computer security alerts within a series of time windows. In particular, the method and system automatically manages; processes; and optimizes in-line and in-transit data blocks or raw information security alerts received from a plurality of information surveillance sources and/or peripheral monitoring devices simultaneously. The data blocks or raw information security alerts that are found to be unique in the various time windows are transposed into meta-definition tables to be further processed while redundant data blocks or raw alerts contained within each particular time window are identified, marked and processed accordingly.

  • Patent number: 10713586
    Abstract: This document discloses a system and method for consolidating threat intelligence data for a computer and its related networks. Massive volumes of raw threat intelligence data are collected from a plurality of sources and are partitioned into a common format for cluster analysis whereby the clustering of the data is done using unsupervised machine learning algorithms. The resulting organized threat intelligence data subsequently undergoes a weighted asset based threat severity level correlation process. All the intermediary network vulnerabilities of a particular computer network are utilized as the critical consolidation parameters of this process. The final processed intelligence data gathered through this high speed automated process is then formatted into predefined formats prior to transmission to third parties.

  • Patent number: 10693904
    Abstract: A system and method for disrupting an information security threat that constitutes an attack on a computer asset in a computer network is provided. The provided system and method disrupts this information security threat after the attack on the computer asset has been detected by at least one of the monitoring devices on the affected computer network. An intermediate upstream gateway of the affected computer network is then utilized to disrupt this information security threat. As the detected attack is being disrupted, a mitigation action will be automatically initiated if a mitigation action associated with the attack is stored in the system's database; else information about the attack will be sent to a central command centre for further assessment. At the central command centre, a mitigating action will be further developed and executed to address the intention of the attack.

  • Patent number: 10419453
    Abstract: This invention relates to a system and method for simultaneously displaying real-time information security threat posture of a plurality of computers and its intermediary networks that are under surveillance. In particular, the invention involves displaying a three-dimensional abstract object that has been scaled according to the size and orientation of a display screen so that the entirety of the three-dimensional abstract object may be simultaneously viewed by viewers of the display technology in its entirety. The displayed three-dimensional abstract object is made up of an amalgamation of semi-translucent three-dimensional shapes that are arranged together to achieve the unified shape and form of the three-dimensional abstract object.

  • Patent number: 10237297
    Abstract: A system and method for evaluating cyber-security threat incidents of a computer network is described in this document. In particular, it is described that cyber-security threat incidents of a computer network may be visualized by displaying these threat incidents as a plurality of graphical objects on a display of a device. A subset of these graphical objects or threat incidents may then be selected by applying a single continuous touch input to a touch interface of the device. A risk score will then be generated and displayed based on the threat incidents that are contained within the subset of graphical objects. Mitigation actions addressing the cyber-security threats that triggered these threat incidents are then implemented by the device.
