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 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.

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 policy enforcement group of network elements, of the identified network elements, that maps to the list of network addresses associated with the specific host threat, where the network control system is associated with the policy enforcement group of 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: Techniques are disclosed for redirecting network traffic of virtualized application workload to a host-based firewall. For example, a system comprises a software defined networking (SDN) controller of a multi-tenant virtualized data center configured to: receive a security policy expressed as one or more tags to redirect traffic of a virtualized application workload to a host-based firewall (HBF) of the multi-tenant virtualized data center; configure network connectivity to the HBF in accordance with the security policy; a security controller that manages the HBF configured to: obtain the one or more tags from the SDN controller; receive one or more firewall policies expressed in terms of the one or more tags, wherein each of the one or more firewall policies specifies a function of the HBF; and configure the function of the HBF in accordance with the one or more firewall policies.

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 policy enforcement group of network elements, of the identified network elements, that maps to the list of network addresses associated with the specific host threat, where the network control system is associated with the policy enforcement group of 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 receives policy information indicating a policy to be implemented for an application hosted by multiple cloud domains, and receives, from the multiple cloud domains, different application resource tags and addresses associated with the application. The device maps the different application resource tags to a generic identifier, and associates the policy with the generic identifier and with the addresses associated with the application. The device provides, based on associating the policy with the generic identifier and with the addresses associated with the application, the policy to the multiple cloud domains to permit the multiple cloud domains to implement the policy.

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. The device may modify information related to the set of security rules to cause the implementation of the set of security rules to be controlled by the set of conditions. The modification to cause the device to process the set of security rules to dynamically implement the set of security actions based on satisfaction of the set of conditions. The device may perform an action after modifying the information.
