The present disclosure combines Software Defined Networks (SDN) concepts with Security concepts. The coordination between SDN and Security provides a myriad of advantageous use cases. One exemplary use case involves providing a fast path at network speeds using SDN by routing network traffic to bypass a security appliance once the security appliance determines that the security appliance no longer needs to inspect the network traffic. Another exemplary use case involves remote provisioning of security zones.

Providing a fast path between two entities

Systems, methods, and apparatuses enable agent-less network traffic interception using an overlay network. The system creates an inspection namespace on a server computer and clones namespace properties of a default namespace on the server computer to the inspection namespace. The system creates an overlay network in the inspection namespace connecting the server computer to a security service. The system creates a namespace bridge between the default namespace and the inspection namespace to pass server traffic between the namespaces. The system then transmits server traffic to the security service using the overlay network and an encapsulation protocol.

Agent-less network traffic inspection using an overlay network

A method is provided in one example embodiment that includes receiving metadata from a host over a metadata channel. The metadata may be correlated with a network flow and a network policy may be applied to the connection. In other embodiments, a network flow may be received from a host without metadata associated with the flow, and a discovery redirect may be sent to the host. Metadata may then be received and correlated with the flow to identify a network policy action to apply to the flow.

System and method for redirected firewall discovery in a network environment

Systems and methods are disclosed that relate to network security within a virtual network, and how to add microservices in a scalable virtual network. For example, one embodiment discloses a method of receiving a deployment request to deploy a security microservice in a security service, the deployment request including a deployment specification. The method further includes determining whether an interface microservice is available on one or more hosts by accessing one or more host records for the one or more hosts, and selecting a host on which to deploy the security microservice utilizing the deployment specification. When the interface microservice does not exist on the selected host, the method further includes initializing the interface microservice on the selected host, attaching the interface microservice to a hypervisor of the selected host, connecting the security microservice to the interface microservice of the selected host, and deploying the security microservice on the selected host.

Systems and methods for adding microservices into existing system environments

Systems and methods are described herein generally relating to network security, and in particular, embodiments described generally relate to systems and methods for selecting microservices to process protocol data streams. For example, a method is disclosed, which calls for receiving a protocol packet, the protocol packet comprising a sequence number, generating a difference by subtracting a protocol message base from the sequence number, generating a first quotient by dividing the difference by a protocol common message length, generating a second value using the first quotient, determining a Transmission Control Protocol (TCP) reassembly resource using the generated second value, and transmitting the protocol packet to the determined TCP reassembly resource.

Systems and methods for selecting microservices to process protocol data streams

Technologies are provided in example embodiments for analyzing an encrypted network flow. The technologies include monitoring the encrypted network flow between a first node and a second node, the network flow initiated from the first node; duplicating the encrypted network flow to form a copy of the encrypted network flow; decrypting the copy of the encrypted network flow using a shared secret, the shared secret associated with the first node and the second node; and scanning the network flow copy for targeted data.

Encrypted data inspection in a network environment

A method is provided in one example embodiment that includes intercepting a network flow to a destination node having a network address and sending a discovery query based on a discovery action associated with the network address in a firewall cache. A discovery result may be received and metadata associated with the flow may be sent to a firewall before releasing the network flow. In other embodiments, a discovery query may be received from a source node and a discovery result sent to the source node, wherein the discovery result identifies a firewall for managing a route to a destination node. Metadata may be received from the source node over a metadata channel. A network flow from the source node to the destination node may be intercepted, and the metadata may be correlated with the network flow to apply a network policy to the network flow.

System and method for host-initiated firewall discovery in a network environment

User names and user groups serve as the basis of a formal policy in a network. A passive monitor examines network traffic in near real time and indicates: which network traffic is flowing on the network as before; which users or user groups were logged into workstations initiating this network traffic; and which of this traffic conforms to the formal policy definition. In one embodiment of the invention, users and user groups are determined by querying Microsoft&#xae; Active Directory and Microsoft&#xae; Windows servers, to determine who is logged onto the Microsoft&#xae; network. Other sources of identity information are also possible. The identity information is then correlated with the network traffic, so that even traffic that does not bear on the Microsoft&#xae; networking scheme is still tagged with identity

Identities correlation infrastructure for passive network monitoring

A policy developer studio comprising: a meta-policy core of network objects, a policy developer graphical user interface (GUI) tool for providing a front end to a policy language, an output in XML, a compiled output for a policy engine, and an output in human readable form is provided.
