Abstract
Systems and methods for use in secure network communication. A physical network interface receives a network packet associated with a security level. The network packet is transmitted from the physical network interface to a security policy component. The network packet is routed to a stack offload engine by the security policy component based on a network address associated with the network packet and the security level associated with the network packet. The network packet is provided by the stack offload engine to a software application via trusted memory interface that transfers the packet to a memory portion of a plurality of memory portions. The memory portion corresponds to the security level.
