  • Patent number: 11902328
    Abstract: Machine learning techniques are described for analyzing information network traffic to identify different devices connected to a network. Transmitted network packets may be passively collected and analyzed. In some cases the described techniques may be used to identify distinct devices connected to a network even though the collected and analyzed packets may lack a unique device identifier, such as a media access control (MAC) identifier, corresponding to a device that originated the packets.

  • Patent number: 11863401
    Abstract: Techniques are disclosed for generating a combined visual representation of subsets of devices associated with corresponding sub-networks of a private network, where at least two devices in corresponding sub-networks share a same private internet protocol (IP) address. The system generates a separate profile for each device using a combination of elements including at least (a) a private IP address corresponding to the device and (b) a network identifier corresponding to a sub-network associated with the device. These sub-networks and their constituent devices may be visually represented in corresponding user interface elements.

  • Patent number: 11770400
    Abstract: Presenting, at a graphical user interface (GUI), device photos and risk categories associated with devices in a network is described. Data packets communicated in a network are detected. Based on the detected data packets, a set of devices in the network are determined. A set of device photos associated respectively with the set of devices are determined. A GUI concurrently presents the set of device photos to indicate the set of devices detected in the network. The set of devices may be filtered, sorted, and/or grouped based on various criteria. The GUI may present the device photos according to the filtering, sorting, and/or grouping. Additionally or alternatively, risk scores associated respectively with the set of devices are determined. The set of devices are categorized into respective risk categories based on the associated risk scores. A GUI concurrently presents a set of risk categories and information associated with each risk category.

  • Publication number: 20220247786
    Abstract: Techniques for generating and enforcing security policies for device clusters are disclosed. A security manager generates a plurality of clusters of devices for applying security policies. For each cluster of devices, the security manager trains a machine learning model to indicate whether a particular data flow associated with a device in the particular cluster of devices is allowed or denied. The security manager detects a data flow corresponding to a device. If the security manager determines that the device corresponds to a first cluster of devices, the security manager identifies a first trained machine learning model corresponding to the first cluster of devices. The security manager applies the first trained machine learning model to the first data flow to determine whether the first data flow is to be allowed or denied. The security manager allows or denies the first data flow based on the applying operation.

  • Publication number: 20220004960
    Abstract: Systems and methods described may deduce that a machine is in use for a period of time preceding and/or subsequent to a detected operation. The deduction of the usage period may be based on a type of the detected operation.

  • Patent number: 10795745
    Abstract: The present disclosure discloses a method and a network device for failure detection of nodes in a cluster. Specifically, a network device transmits data to another device at a first time. The network device then receives an acknowledgment of the data from the second device at a second time. Next, the network device determines a Round Trip Time (RTT) for the first device and the second device based on the first time and the second time. Based on the RTT, the network device determines a first frequency for transmitting a heartbeat protocol message between the first device and the second device, and transmits a heartbeat protocol message between the first device and the second device at the first frequency.

  • Patent number: 10742687
    Abstract: Techniques for determining a device profile and anomalous behavior associated with a device in a network are disclosed. Attribute values associated with a target device are determined based on data packets detected from a network. A subset of a set of classifiers associated with the available attribute values are selected. The attribute values are applied to the selected classifiers to determine a respective candidate device profile. A current device profile is determined for the target device based on the candidate device profiles. The current device profile indicates expected attribute values for the target device. Current attribute values are compared to the expected attribute values to determine whether there is any anomalous behavior associated with the target device.
