Methods, systems, and media for producing a firewall rule set are provided herein. Exemplary methods may include receiving a declarative policy associated with a computer network security policy; collecting information from at least one external system of record; generating a firewall rule set using the declarative policy and information, the firewall rule set including addresses to or from which network communications are permitted, denied, redirected or logged, the firewall rule set being at a lower level of abstraction than the declarative policy; and provisioning the firewall rule set to a plurality of enforcement points of a distributed firewall, the firewall selectively policing network communications among workloads using the firewall rule set.

Conditional declarative policies

Context aware microservice networks and contextual security policies for microservice networks are provided herein. In some embodiments, a system includes a plurality of microservices, each of the plurality of microservices having a plurality of distributed microservice components. At least a portion of the distributed microservice components execute on different physical or virtual servers in a data center or a cloud. The system also includes a plurality of logical security boundaries, with each of the plurality of logical security boundaries being created by a plurality of enforcement points positioned in association with the plurality of distributed microservice components. Each of plurality of microservices is bounded by one of the plurality of logical security boundaries.

Context aware microsegmentation

Systems for providing scanning within distributed services are provided herein. In some embodiments, a system includes a plurality of segmented environments that each includes an enforcement point that has an active probe device, and a plurality of workloads that each implements at least one service. The system also has a data center server coupled with the plurality of segmented environments over a network. The data center server has a security controller configured to provide a security policy to each of the plurality of segmented environments and an active probe controller configured to cause the active probe device of the plurality of segmented environments to execute a scan.

Segmented networks that implement scanning

Systems and methods for delivering security functions to a distributed network are described herein. An exemplary method may include: processing a data packet received from a switch, the data packet directed to the at least one network asset; selectively forwarding the data packet using the processing and a rule set; inspecting the forwarded packet; directing the enforcement point to at least one of forward the data packet to the at least one network asset and drop the data packet, using the inspection and the rule set; accumulating data associated with at least one of the data packet, the processing, and the inspection; analyzing the at least one of the data packet, the processing, and the inspection; and initiating compilation of a high-level security policy by the compiler using the analysis to produce an updated rule set.

Delivering security functions to distributed networks

Methods, systems, and media for a security system are provided herein. Exemplary methods may include: acquiring a firewall security policy from a policy compiler; receiving network traffic originating from a source machine and directed to a destination machine; analyzing the network traffic using the firewall security policy; forwarding or dropping each of the network traffic according to the security policy; and redirecting one or more network packets of the network traffic according to the security policy.

System and method for threat-driven security policy controls

Systems for providing vulnerability scanning within distributed microservices are provided herein. In some embodiments, a system includes a plurality of microsegmented environments that each includes a hypervisor, an enforcement point that has an active probe device, and a plurality of virtual machines that each implements at least one microservice. The system also has a cloud data center server coupled with the plurality of microsegmented environments over a network. The cloud data center server has a security controller configured to provide a security policy to each of the plurality of microsegmented environments and an active probe controller configured to cause the active probe device of the plurality of microsegmented environments to execute a vulnerability scan.

Microsegmented networks that implement vulnerability scanning

Methods, systems, and media for a security system are provided herein. Exemplary methods may include: acquiring a firewall security policy from a policy compiler; receiving network traffic originating from a source machine and directed to a destination machine; analyzing the network traffic using the firewall security policy; forwarding or dropping each of the network traffic according to the security policy; accumulating the network traffic and metadata associated with the network traffic; and initiating an update to the firewall security policy by the policy compiler using at least one of the accumulated network traffic and metadata.

A method and apparatus for dynamic security insertion into virtualized networks is described. The method may include receiving, at a network device from a second network device, a data packet and application data extracted from the data packet. The method may also include generating a routing decision for a network connection associated with the data packet based, at least in part, on the application data. Furthermore, the method may include transmitting the routing decision for the data packet to the second device for the second device to route the data based on the routing decision.

System and method for dynamic security insertion in network virtualization

A network system includes a security device and a network access device. The network access device is to receive a packet from a source node destined to a destination node, and to examine a data structure maintained by the network access device to determine whether the data structure stores a data member having a predetermined value, the data member indicating whether the packet should undergo security processing. If the data member matches the predetermined value, the packet is transmitted to a security device associated with the network access device to allow the security device to perform content inspection, and in response to a response received from the security device, the packet is routed to the destination node dependent upon the response. The packet is routed to the destination node without forwarding the packet to the security device.

Cooperative network security inspection

A method and apparatus is disclosed herein for using a virtual security boundary. In one embodiment, the method comprises receiving information from a virtual machine after the virtual machine has been moved from a first physical location in a network to a second physical location in the network, where the information identifies the virtual machine as one previously assigned to a security boundary; determining that access to the virtual machine at the first physical location was permitted by the security gateway; assigning the virtual machine at the second physical location to the security boundary, and applying a security policy associated with the security boundary to communications between the network and the virtual machine at the second physical location.
