  • Patent number: 11924072
    Abstract: Systems, methods, and computer-readable media for annotating process and user information for network flows. In some embodiments, a capturing agent, executing on a first device in a network, can monitor a network flow associated with the first device. The first device can be, for example, a virtual machine, a hypervisor, a server, or a network device. Next, the capturing agent can generate a control flow based on the network flow. The control flow may include metadata that describes the network flow. The capturing agent can then determine which process executing on the first device is associated with the network flow and label the control flow with this information. Finally, the capturing agent can transmit the labeled control flow to a second device, such as a collector, in the network.

  • Publication number: 20240073811
    Abstract: A proactive energy-saving processing in an access point (AP) device is described. The AP monitors/computes usage/operating parameters (load factors) of the AP, and based on the obtained parameters, adjusts one or more AP operating parameters to reduce power consumption. The process is proactive in the sense that the current conditions in the AP do not require scaling back AP functionality. Nonetheless, the AP can scale back some functionality to reduce its power consumption, proactively, despite the absence of a need to do so.

  • Patent number: 11902121
    Abstract: A method includes capturing first data associated with a first packet flow originating from a first host using a first capture agent deployed at the first host to yield first flow data, capturing second data associated with a second packet flow originating from the first host from a second capture agent deployed on a second host to yield second flow data and comparing the first flow data and the second flow data to yield a difference. When the difference is above a threshold value, the method includes determining that the second packet flow was transmitted by a component that bypassed an operating stack of the first host or a packet capture agent at the device to yield a determination, detecting that hidden network traffic exists, and predicting a malware issue with the first host based on the determination.

  • Patent number: 11902122
    Abstract: An approach for establishing a priority ranking for endpoints in a network. This can be useful when triaging endpoints after an endpoint becomes compromised. Ensuring that the most critical and vulnerable endpoints are triaged first can help maintain network stability and mitigate damage to endpoints in the network after an endpoint is compromised. The present technology involves determining a criticality ranking and a secondary value for a first endpoint in a datacenter. The criticality ranking and secondary value can be combined to form priority ranking for the first endpoint which can then be compared to a priority ranking for a second endpoint to determine if the first endpoint or the second endpoint should be triaged first.

  • Patent number: 11902123
    Abstract: Systems, methods, and computer-readable media for managing compromised sensors in multi-tiered virtualized environments. In some embodiments, a system can receive, from a first capturing agent deployed in a virtualization layer of a first device, data reports generated based on traffic captured by the first capturing agent. The system can also receive, from a second capturing agent deployed in a hardware layer of a second device, data reports generated based on traffic captured by the second capturing agent. Based on the data reports, the system can determine characteristics of the traffic captured by the first capturing agent and the second capturing agent. The system can then compare the characteristics to determine a multi-layer difference in traffic characteristics. Based on the multi-layer difference in traffic characteristics, the system can determine that the first capturing agent or the second capturing agent is in a faulty state.

  • Publication number: 20230354397
    Abstract: Systems, methods, and computer-readable media are disclosed for applying quality metrics for resource unit (RU) allocation in connection with a wireless access point (AP). In response to detecting threshold utilization of an AP by multiple wireless clients, an RU score is initialized. For each initialized RU score, an updated RU score is periodically computed. To perform this computation several steps are performed. First, RU quality metrics are received. Next, each quality metric is multiplied by an associated weighting coefficient. Finally, the quality products are summed to provide an updated RU score. In response to determining that a puncture candidate RU has a puncture candidate RU score below a predetermined threshold, one or more RUs are punctured or otherwise de-prioritized. A request to assign new RUs is received. In response to the request to assign the new RUs, the new RUs are assigned based on the periodically updated RU scores.
