摘要： A cloud computer system is provided that includes a plurality of computer devices and a database. The plurality of computer devices execute a plurality of virtual machines, with one of the virtual machines serving as a controller node and the remainder serving as worker instances. The controller node is programmed to accept a request to initiate a distributed process that includes a plurality of data jobs, determine a number of worker instances to create across the plurality of computer devices, and cause the number of worker instances to be created on the plurality of computer devices. The worker instances are programmed to create a unique message queue for the corresponding worker instance, and store a reference for the unique message queue that was created for the corresponding worker to the database. The controller node retrieves the reference to the unique message queues and posts jobs to the message queues for execution by the worker instances.

摘要： Systems and methods are provided for automatically discovering applications/clusters in a network and mapping dependencies between the applications/clusters. A network monitoring system can capture network flow data using sensors executing on physical and/or virtual servers of the network and sensors executing on networking devices connected to the servers. The system can determine a graph including nodes, representing at least the servers, and edges, between pairs of the nodes of the graph indicating the network flow data includes one or more observed flows between pairs of the servers represented by the pairs of the nodes. The system can determine a dependency map, including representations of clusters of the servers and representations of dependencies between the clusters, based on the graph. The system can display a first representation of a first cluster of the dependency map and information indicating a confidence level of identifying the first cluster.

摘要： A method of determining the presence of a loopback in one or more networks comprises storing information related to a test instance; sending a loopback detection beacon (LPDB) containing information related to the test instance from a port on an originating device; monitoring the port for a predetermined time period to detect LPDBs arriving at the port during the predetermined time period; and determining whether a detected LPDB contains information corresponding to the stored information, to detect the presence of a loopback. The method may determine whether a detected loopback is a port loopback, a tunnel loopback or a service loopback. The stored information related to the test instance may be deleted if an LPDB arriving at the port and containing information corresponding to the stored information is not detected within the predetermined time period.

摘要： A lateral movement identification tool analyzes communications sent and received from a local host to identify potential instances of lateral movement. When the host-based lateral movement identification tool identifies a host to host connection, the tool processes one or more artificial intelligence algorithms to analyze information from local network resources including a directory service, a local network system such as a network basic input/output system, a domain name system, and event logs. The lateral movement identification tool correlates the aggregated information with identified host to host messaging and sends alerts when lateral movement is suspected. Alerts may be either presented locally or provided to a central console based on configuration information.

摘要： A device comprising: a transceiver operable in a first or second mode and configured to receive packets from a remote device, each packet comprising an indication of whether or not the remote device has a further packet to transmit, wherein: in the first mode the transceiver: (i) sends a polling message in response to receiving the indication of a further packet for transmission; and (ii) listens for that further packet; and in the second mode the transceiver: (i) does not send a polling message in response to receiving the indication of a further packet for transmission; and (ii) listens for packets regardless of whether a received packet indicates that there is a further packet to transmit or not; and a controller configured to monitor an activity level for the transceiver and cause the transceiver to operate in the first or second mode in dependence on the activity level.

摘要： Systems and methods for device-state quality analysis include generating polling schedules based on which accessory devices have yet to be polled, which accessory devices are associated with less than favorable previous polling results, and/or which accessory devices are associated with a priority polling request. Polling requests may be generated using the schedules and the polling requests may be sent to systems associated with the accessory devices. Those systems may return current device-state data, which may be compared to stored device-state data to determine an accuracy value for the stored device-state data. Quality data may be generated using these accuracy values.

摘要： This application relates to a device type identification method performed by a computer device. The method includes: transmitting a port open/closed state probe packet to at least two target devices; receiving port open/closed state information returned by the at least two target devices in response to the port open/closed state probe packet, wherein the port open/closed state information comprises port open/closed state vectors indicating whether each port of the at least two target devices is open or closed; extracting a port open/closed state feature from the port open/closed state information; performing decision classification on the port open/closed state feature through a decision tree classifier; and determining a device type of each of the at least two target devices according to a result obtained from the decision classification.

摘要： An application may perform operations within a first secure enclave of a processing device. The application may provide secure monitoring data, such as secure heartbeat information. The monitoring data and an application identity may be verified at a second secure enclave of the processing device using local attestation operations. A remote attestation signature may be generated at the second secure enclave based on the monitoring data, the application identity, and a node private key. A monitoring message signature may be generated at the first secure enclave based on an application private key and a message payload that includes the monitoring data, the application identity, and the remote attestation signature. A monitoring message that includes the payload and monitoring message signature may be sent from the first secure enclave to a monitoring system, which may verify the message to detect unauthorized changes to the monitoring data or the application identity.

摘要： Systems, methods, and computer-readable media for identifying a spanning tree loop in a network environment. Spanning tree loop indicators occurring in a network environment that utilizes a spanning tree protocol are identified. The spanning tree loop indicators are correlated to identify correlated spanning tree loop indicators within the network environment. A potential spanning tree loop is recognized from a plurality of the correlated spanning tree loop indicators based on indicator types of the correlated spanning tree loop indicators. The potential spanning tree loop is remedied in the network environment in response to recognizing the potential spanning tree loop in the network environment.
