  • Patent number: 11948575
    Abstract: Implementations set forth herein relate to an automated assistant that uses circumstantial condition data, generated based on circumstantial conditions of an input, to determine whether the input should affect an action been initialized by a particular user. The automated assistant can allow each user to manipulate their respective ongoing action without necessitating interruptions for soliciting explicit user authentication. For example, when an individual in a group of persons interacts with the automated assistant to initialize or affect a particular ongoing action, the automated assistant can generate data that correlates that individual to the particular ongoing action. The data can be generated using a variety of different input modalities, which can be dynamically selected based on changing circumstances of the individual. Therefore, different sets of input modalities can be processed each time a user provides an input for modifying an ongoing action and/or initializing another action.

  • Patent number: 11870755
    Abstract: Systems and methods provide for provisioning a dynamic intent-based firewall. A network controller can generate a master route table for network segments reachable from edge network devices managed by the controller. The controller can receive zone definition information mapping the network segments into zones and Zone-based Firewall (ZFW) policies to apply to traffic between a source and destination zone specified by each ZFW policy. The controller can evaluate a ZFW policy to determine first edge network devices that can reach first network segments mapped to the source zone specified by the ZFW policy, second edge network devices that can reach second network segments mapped to the destination zone specified by the ZFW policy, and routing information (from the route table) between the first network segments, the first and second edge network devices, and the second network segments. The controller can transmit the routing information to the edge network devices.

  • Patent number: 11397808
    Abstract: Infrastructure attacks based on graph edge context are identified by receiving an execution graph constructed by a central service based on behaviors monitored by a plurality of agents deployed on respective systems including a first system. The execution graph comprises a plurality of execution trails. One or more tags are applied to each edge of an execution trail of the execution graph based on at least one of temporal context or spatial context associated with the edge. One or more behaviors associated with the edge of the execution trail happen across an enterprise infrastructure involving the first system. The execution trail enriched with the one or more tags is analyzed. An action that is performed to mitigate security risks in the execution graph is determined based on the analysis.

  • Patent number: 11088915
    Abstract: Systems, methods, and computer-readable media for predicting policy changes in a network environment through a data serialization language. Running configurations of one or more network devices in a network environment can be collected. Further, a master device template of a new policy for the network environment can be generated through a data serialization language based on the running configurations of the one or more network devices. The master device template can include a directory-based tree structure of a simulated implementation of the new policy in the network environment. Policy changes in the network environment for the new policy can be predicted before implementing the new policy in the network environment based on simulated packet traversal through the directory-based tree structure of the simulated implementation of the policy in the network environment.

  • Patent number: 10944630
    Abstract: The present technology is directed to an automated end to end network migration process from on-premise to cloud-based management platforms and visa-versa. The disclosed technology describes an enhanced plug and play (PnP) software agent operationally coupled to a device and capable of interacting with a PnP service hosted on a target management platform to thereby initiate the migration process. The PnP service on the target management platform upon receiving a migration request from the device PnP agent, maps the requesting device onto a client profile existing on the target management platform and identifies therefrom the associated default controller for the device. Subsequently, the device is directed to acquire and boot up on a new software image compatible with the target management platform and following a conversion of its existing configuration into a version compatible with the new software image, the device is migrated to the associated default controller.
