  • 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.

  • Publication number: 20230118563
    Abstract: An example method includes detecting, using sensors, packets throughout a datacenter. The sensors can then send packet logs to various collectors which can then identify and summarize data flows in the datacenter. The collectors can then send flow logs to an analytics module which can identify the status of the datacenter and detect an attack.

  • Patent number: 11601349
    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 outside of the first 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 a hidden process exists and corrective action can be taken.

  • Patent number: 11504657
    Abstract: A filter assembly and a method of operating the same to detect water leaks are provided. The filter assembly includes a filter housing for receiving a filter cartridge and at least partially defining a drain trough positioned below the filter cartridge for collecting leaked water. A light source is positioned proximate the drain trough for directing light through the drain trough and a light sensor is positioned proximate the drain trough for sensing the light directed through the drain trough. A controller uses the light sensor to monitor the light generated by the light source and determines that a leak exists when an intensity of sensed light is reduced by the leaked water.

  • Patent number: 11477097
    Abstract: Systems, methods, and computer-readable media for hierarchichal sharding of flows from sensors to collectors. A first collector can receive a first portion of a network flow from a first capturing agent and determine that a second portion of the network flow was not received from the first capturing agent. The first collector can then send the first portion of the network flow to a second collector. A third collector can receive the second portion of the network flow from a second capturing agent and determine that the third collector did not receive the first portion of the network flow. The third collector can then send the second portion of the network flow to the second collector. The second collector can then aggregate the first portion and second portion of the network flow to yield the entire portion of the network flow.

  • Patent number: 11368378
    Abstract: Systems, methods, and computer-readable media for identifying bogon addresses. A system can obtain an indication of address spaces in a network. The indication can be based on route advertisements transmitted by routers associated with the network. The system can receive a report generated by a capturing agent deployed on a host. The report can identify a flow captured by the capturing agent at the host. The system can identify a network address associated with the flow and, based on the indication of address spaces, the system can determine whether the network address is within the address spaces in the network. When the network address is not within the address spaces in the network, the system can determine that the network address is a bogon address. When the network address is within the address spaces in the network, the system can determine that the network address is not a bogon address.

  • Publication number: 20220151170
    Abstract: Optimising water use in a way that avoids over watering or at least avoids or minimises water mobilisation may be useful. An irrigation control system is described, the system including a sound emitter arranged to emit sound towards a ground surface; a sound receiver arranged to receive sound emitted by the sound emitter and reflected or scattered from the ground surface. A controller then controls one or more irrigation parameters of an irrigator based at least in part on sound received by the sound receiver. In a further aspect, the irrigation control system senses the onset of surface water pooling or free water flow on the ground surface and the controller then controls irrigation parameters to reduce application of water in response to the sensed features. Related methods of controlling irrigation systems are also described.

  • Patent number: 11327066
    Abstract: A contaminant measurement system is provided. The system is operable to detect and measure a concentration level of a preselected contaminant, e.g., lead, in water disposed within a chamber of the system. The system includes a detection agent that is operable to interact with the preselected contaminant in the water. The detection agent can be a plurality of polymeric beads or a membrane, for example. The system has a sensing circuit that includes a pair of electrodes spaced from one another and both at least partially disposed in the water. A controller is communicatively coupled with the sensing circuit and is configured to receive one or more electric signals from the sensing circuit. The controller determines a parameter indicative of the concentration level of the preselected contaminant based on the one or more electrical signals. The controller then determines and outputs the concentration level of the preselected contaminant.

  • Publication number: 20220131773
    Abstract: A network analytics system can receive first sensor data, including first network activity and a first timestamp associated with a first clock of a first node, and second sensor data, including second network activity and a second timestamp associated with a second clock of a second node. The system can determine a first delta between the first clock and a third clock based on the first timestamp, and a second delta between the second clock and the third clock. The system can determine a first communication latency associated with a first sensor of the first node, and a second communication latency associated with a second sensor of the second node. The system can generate a report that synchronizes one or more data flows between the first node and the second node based on the first delta, the second delta, the first communication latency, and the second communication latency.

  • Publication number: 20220121456
    Abstract: A system comprises data processing hardware and memory hardware. The memory hardware is in communication with the data processing hardware, and stores instructions that, when executed on the data processing hardware, cause the data processing hardware to perform a plurality of operations. In some examples, one of the operations may include receiving instance management configuration data for a single-tenant software-as-a-service (SaaS) application. Another operation may include further include receiving an image of the single-tenant SaaS application. Yet another operation can include generating, by the control plane manager, a control plane based on the instance management configuration data. The control plane is configured to create multiple instances of the single-tenant SaaS application based on the received image, and to manage the instances of the single-tenant SaaS application based on the received instance management configuration data.
