Abstract: A device receives network segment information identifying network segments associated with a network, and receives endpoint host session information identifying sessions associated with endpoint hosts communicating with the network. The device generates, based on the network segment information and the endpoint host session information, a data structure that includes information associating the network segments with the sessions associated with the endpoint hosts. The device updates the data structure based on changes in the sessions associated with the endpoint hosts and based on changes in locations of the endpoint hosts within the network segments, and identifies, based on the data structure, a particular endpoint host, of the endpoint hosts, that changed locations within the network segments. The device determines a threat policy action to enforce for the particular endpoint host, and causes the threat policy action to be enforced, by the network, for the particular endpoint host.

Abstract: A method for visualizing network flows of a network is provided. The method monitors network flows between a group of machines in a network. The method associates identifiers with the monitored network flows. The method aggregates the monitored network flows into a set of groups based on the associated identifiers. The method displays a set of flow records for the each group of the set of groups.

Abstract: Some embodiments provide a method for defining an adaptable monitoring profile for a network. The defined network monitoring profile is independent of the security policy defined for the network and includes one or more log generation rules, each of which defines a logging policy for a set of data compute nodes (DCNs) that share a common attribute. A log generation rule specifies whether the network activities of a set of DCNs that share a common attribute should be logged or not. A log generation rule can also specify other logging parameters such as priority level of the logs and the required logging protocol for transmission of the logs. The logging policy of a log generation rule is associated with a set of service rules (e.g., firewall rules) through a dynamic service group, and is applied to the service rules when any of these rules is triggered.

Abstract: A device may receive policy information associated with a first application group and a second application group. The device may receive network topology information associated with a network. The device may generate a first policy based on the policy information and the network topology information, and generate a second policy based on the policy information and the network topology information. The device may provide, to the virtual network device, information associated with the first policy to permit the virtual network device to implement the first policy in association with network traffic transferred between the first application group and the second application group. The device may provide, to the physical network device, information associated with the second policy to permit the physical network device to implement the second policy in association with network traffic transferred between the first application group and the second application group.

Abstract: A device may receive information identifying a set of conditions related to controlling implementation of a set of security rules. The set of conditions may be associated with a set of security actions that a device is to perform based on whether the set of conditions is satisfied. The device may determine the set of security rules that is to be controlled by the set of conditions using information related to the set of security rules.

Abstract: A device receives information identifying a specific host threat to a network, where the information includes a list of network addresses associated with the specific host threat. The device identifies network elements, of the network, associated with the specific host threat to the network, and determines a network control system associated with the identified network elements.

The device determines a threat policy action to enforce for the specific host threat, and causes, via the network control system, the threat policy action to be enforced by the policy enforcement group of network elements.

Abstract: A device may receive first information associated with a set of security rules. The first information may identify a set of security actions a device is to implement when the set of security rules applies to traffic. The device may determine a manner in which the set of security rules is to apply using the first information. The device may determine whether the manner in which the set of security rules is to apply and an intent of a network security policy or a manner in which a set of previously defined security rules is to apply match to determine whether the set of security rules conflicts with the network security policy or whether the set of security rules and the set of previously defined security rules are related. The device may perform an action.
