Abstract: Methods and systems are provided for network security. In one embodiment, the method involves receiving a data packet (e.g., from a firewall). The method also involves running an inspection of the received data packet within a virtual network, the virtual network duplicating at least a portion (e.g., servers(s) and/or application(s)) of a protected network. The method further involves sending the inspected data packet, or portion and/or modified version thereof, to the protected network, in response to the data packet passing the inspection within the virtual network. The method also involves blocking passage of the data packet to the protected network, in response to the data packet failing the inspection.

Abstract: Techniques are provided for establishment of multiple concurrent virtual networks. In one example, there is provided a method operable by a message management unit (MMU) or the like. The method may involve establishing communication handles with a plurality of virtual network interfaces (VNIs) operatively coupled to an operating system, and establishing a network communications socket (NCS) operatively connected to a plurality of virtual layered networks. The method may involve establishing data channels that couple the MMU and its components with the respective VNIs of the MMU, and allowing the virtual layered networks to be concurrently transported on top of physical network(s). The method may involve facilitating communication between the operating system and the virtual layered networks via the combination of the established data channels, the established handles and a network software stack of the operating system.

Abstract: Techniques are provided for establishment of multiple concurrent virtual networks. In one example, there is provided a method operable by a virtual network controller (VNC) or the like. The method may involve establishing communication links with a plurality of virtual network interfaces (VNIs) operatively coupled to a plurality of virtual networks. The method may involve establishing a single port communication link with an operating system. The method may involve allowing the virtual networks to be transported on top of a physical network, and facilitating communication between the operating system and the virtual networks via the single port communication link.
