  • Patent number: 11516239
    Abstract: System, device, and method of adaptive network protection for managed Internet-of-Things (IoT) services. A network traffic monitoring unit monitors data traffic, operations-and-management traffic, and control messages, that relate to cellular communication between an IoT device and a core cellular network. An IoT grouping unit groups multiple IoT devices into a particular IoT group. A baseline behavior determination unit determines a Regular Baseline Cellular Communication Behavior (RBCCB) profile that characterizes the cellular communications that are outgoing from and incoming to each member of the particular IoT group. An outlier detector subsequently detects that a particular IoT device of that particular IoT group, exhibits cellular traffic characteristics that are abnormal relative to the RBCCB profile that was characterized for that particular IoT group.

  • Patent number: 11089049
    Abstract: A system monitors network activity of an end-user device that communicates with servers over a communications network. The performs analysis of packets of data that are transported via the network. The system detects a first set of communications in which a first server infects the end-user device with a cryptocurrency mining malware; a second set of communications, in which a second server activates the end-user device as an activated cryptocurrency mining bot; and a third set of communications, in which the second server allocates a cryptocurrency mining task to the end-user device and later receives a cryptocurrency mining output from the end-user device. The system determines that the first server is a malicious infecting web-server; that the second server is a malicious Command and Control server of a distributed bot-net of cryptocurrency mining bots; and that the end-user device is an infected and activated and operational cryptocurrency mining bot.

  • Patent number: 10749798
    Abstract: System, device, and method of deploying layer-3 transparent cloud-based proxy network element. A virtual network function is defined between a west-side router and an east-side router. A west-side interface receives east-bound traffic from a west-side Virtual LAN. East-bound queries from the west-bound router, are intercepted and responded to by the west-side interface, the response indicating the MAC address of the west-side router instead of the east-side router. The system enables the virtual network function to transparently intercept network traffic, and to selectively apply to such traffic one or more network functions or operations, prior to forwarding the traffic or a modified version thereof to the east-side router, in a Layer-3 transparent manner.

  • Patent number: 9578547
    Abstract: A method for alleviation of congestion in a mobile communications network includes detecting congested cells in the mobile communications network, identifying subscribers with active data sessions in the congested cells; and optimizing bandwidth usage for at least one of the identified subscribers. A bandwidth optimization system includes a network sampling interface to receive at least subscriber, cell and data session identifiers from a network data packet sampler, where the sampler identifies the identifiers from internal data traffic within a mobile communications network, and a network awareness engine (NAE) to at least cross reference the identifiers with external data traffic output by the mobile communications network to at least detect congested cells and associated subscriber data sessions emanating from the mobile communications network.

  • Patent number: 9391901
    Abstract: System and method of predictive Internet traffic steering. An Internet steering gateway decouples between traffic classification and traffic steering, and includes: a deep packet inspection (DPI) utility to ascertain an indication of a destination remote application server (RAS) from an initial packet of a data session in a network; a RAS database to store an optimization profile for each RAS; and a steering utility to look-up, based on the RAS addressing information that was determined by the DPI utility inspection of the initial packet of the data session, an indicated RAS in the RAS database. The steering utility steers the data session to an external optimization platform (EOP) based on the associated profile in the RAS database.
