Abstract: Some embodiments provide a novel method for collecting and reporting attributes of data flows associated with machines executing on a plurality of host computers to an analysis appliance and providing visual representations of the data to a user. Some embodiments provide a visual representation of the collected data that allows a user to select a set of machines and flows and initiate recommendation generation based on the selected machines and flows. The recommendation generation, in some embodiments, includes identifying flows for which rules have not been defined and filtering the identified rules to remove flows for which rules should not be defined. Some embodiments use the identified rues to identify services and groups associated with the rules and generate recommendations for rules, groups and services based on the identified flows, groups and services. The recommendations, in some embodiments, are implemented as a single PATCH API.

Abstract: Some embodiments provide a method for a network management and control system that manages a virtual infrastructure deployed across a set of datacenters. The method receives a definition of an application to be deployed in the virtual infrastructure. The application definition specifies a requirement that the application receive data traffic from sources external to the virtual infrastructure. Based on the application definition, the method defines a first set of firewall rules for the application that indicate conditions for allowing data traffic from sources external to the virtual infrastructure. For an existing second set of higher-level firewall rules for data traffic entering and exiting the virtual infrastructure, the method specifies a new firewall rule that directs a network element implementing the sets of firewall rules to apply the first set of firewall rules to any data traffic that is from sources external to the virtual infrastructure and directed to the application.

Abstract: Example methods and systems are provided for network diagnosis. One example method may comprise: detecting an egress packet and determining whether each of multiple network issues is detected for the egress packet or a datapath between a first virtualized computing instance and a second virtualized computing instance. The method may also comprise: generating network diagnosis code information specifying whether each of the multiple network issues is detected or not detected; generating an encapsulated packet by encapsulating the egress packet with an outer header that specifies the network diagnosis code information; and sending the encapsulated packet towards the second virtualized computing instance to cause a second computer system to perform one or more remediation actions based on the network diagnosis code information.

Abstract: Some embodiments provide a method for network management and control system that manages one or more logical networks. From a first user, the method receives a definition of one or more security zones for a logical network. Each security zone definition includes a set of security rules for data compute nodes (DCNs) assigned to the security zone. From a second user, the method receives a definition of an application to be deployed in the logical network. The application definition specifies a set of requirements. Based on the specified set of requirements, the method assigns DCNs implementing the application to one or more of the security zones for the logical network.

Abstract: The current document is directed to methods and systems that generate microsegmentation quotients for computational entities and components of a distributed-computer-system. In the described implementation, microsegmentation quotients are generated for each component, subsystem, or computational entity, collectively referred to as “system entities,” of a set of specified system-entity types within the distributed computer system. Microsegmentation quotients are generated for system entities at any of the various hierarchical levels within a distributed computer system, including for the entire distributed computer system. Microsegmentation quotients are generated by an iterative process that refines initial estimates of the microsegmentation quotients for system entities within the distributed computer system.

Abstract: Some embodiments provide a method for visualizing a realization status of configuration changes for a set of logical entities of a logical network. The method generates a first presentation of a list of logical entities and a realization status for each logical entity in the list, where the realization status indicates whether all configuration changes for the logical entity have been realized. In response to a selection of a particular logical entity in the displayed list for which at least one configuration change has not been realized, the method generates a second presentation comprising a view of pending configuration changes for the selected particular logical entity.

Abstract: A system and method for performing firewall operations on an edge service gateway virtual machine that monitors traffic for a network. The method includes detecting, from a directory service executing on a computing device, a login event on the computing device, obtaining, from the detected login event, login event information comprising an identifier that identifies a user associated with the login event, storing the login event information as one or more context attributes in an attribute table, and applying a firewall rule to a data message that corresponds to the one or more context attributes.

Abstract: Behavior-based security in a datacenter includes monitoring user actions made by users in the datacenter. Behavior-based risk scores are computer for users based on their monitored actions. One or more firewall rules are generated for users based on their behavior-based risk scores. The firewall rules regulate the actions of the users.

Abstract: Some embodiments provide a simplified mechanism to deploy and control a multi-segmented application by using application-based manifests that express how application segments of the multi-segment application are to be defined or modified, and how the communication profiles between these segments. In some embodiments, these manifests are application specific. Also, in some embodiments, deployment managers in a software defined datacenter (SDDC) provide these manifests as templates to administrators, who can use these templates to express their intent when they are deploying multi-segment applications in the datacenter. Application-based manifests can also be used to control previously deployed multi-segmented applications in the SDDC. Using such manifests would enable the administrators to be able to manage fine grained micro-segmentation rules based on endpoint and network attributes.
