A computing device (e.g., a policy management server) obtains a segmentation policy that includes a set of rules for controlling network traffic between workloads. The computing device also receives infrastructure feedback regarding configuration of third-party network infrastructure. The computing device uses the infrastructure feedback to identify a discrepancy between the segmentation policy and the configuration of the third-party network infrastructure and triggers a corrective action in response. The corrective action may include providing a notification or suggestive remedy for the discrepancy to the user or automatically remedying the discrepancy.

Segmentation using infrastructure policy feedback

A segmentation server configures and distributes rules for enforcing a segmentation policy that includes one or more virtual patches. The rules including the virtual patches are enforced by distributed enforcement modules that may execute on host devices or on network devices upstream from the host devices. An enforcement module enforces the rules using traffic filters that filter traffic based on network layer data. To implement a virtual patch, the traffic filters are configured to redirect traffic to or from an application being patched to a transparent application proxy. The transparent application proxy implements an application layer filter that filters traffic based on application layer data to block specific types of traffic associated with a vulnerability addressed by the virtual patch.

Virtual patching in a label-based segmented network environment

A policy management server manages a segmentation policy for segmenting a network and a deception policy for implementing deception services. The policy management server distributes segmentation rules and deception rules to distributed enforcement modules that configure respective traffic filters to enforce the policies. The deception rule may be enforced directly by the traffic filter acting as a deception service, or the traffic filter may act as a proxy to an external deception service. The deception service can behave similarly to a real service to obtain information about the malicious actor that is reported to the policy management server to enable the policy management server to take a remedial action. Furthermore, the policy management server may automatically generate the deception policy based on the segmentation policy such that connection requests that are not allowed by the segmentation policy are automatically sent to a deception service.

Protecting network-based services using deception in a segmented network environment

A policy management server detects attack patterns in traffic flows reported by distributed enforcement modules enforcing the segmentation policy. The policy management server generates a traffic flow graph representing traffic flows between workloads or groups of workloads. Traffic flows matching one or more traffic flow patterns may be tagged in the traffic flow graph. For example, if an attack pattern is present in a connection that is blocked under the segmentation policy, the policy management server may block updates to the segmentation policy that attempt to enable the connection or may alert an administrator prior to enabling the update. If an attack pattern is present in a connection that is allowed under the segmentation policy, the segmentation policy may be updated to block the connection, alert an administrator, redirect traffic to a deception service, or take other remedial action.

Managing a segmentation policy based on attack pattern detection

An enforcement module operating on a server or on a network midpoint device obtains a management instruction controlling communications of a target workload. The enforcement module configures a firewall of a network midpoint device upstream from the target workload to enforce the management instruction. The configuration mechanism may be dependent on the particular capabilities and characteristics of the network midpoint device.

Enforcing instructions of a segmentation policy on a network midpoint device

An enforcement mechanism on an operating system instance enforces a segmentation policy on a container. A configuration generation module executing in a host namespace of the operating system instance receives management instructions from a segmentation server for enforcing the segmentation policy on a container. The configuration generation module executes in the host namespace to configure a traffic control and monitoring module in a container namespace associated with the container. The traffic control and monitoring module in the container namespace controls and monitors communications to and from the container in accordance with its configuration. By executing a configuration generation module in the host namespace to configure traffic control and monitoring module in the container namespace, the enforcement mechanism beneficially enables robust and lightweight enforcement in a manner that is agnostic to different containerization protocols.

Infrastructure-agnostic network-level visibility and policy enforcement for containers

A segmentation server configures enforcement of a segmentation policy by allocating enforcement of management instructions between network devices and hosts. The segmentation policy comprises rules that control communications between workloads. For a particular workload, the segmentation server generates management instructions for controlling communications to and from the particular workload in accordance with the rules. The segmentation server determines an allocation of management instructions between enforcement on a host on which the particular workload executes and enforcement on a network device upstream from the workload. The segmentation server sends configuration information to at least one of the host and the network device in accordance with the allocation to enable enforcement of the management instructions.
