Integrated multi-level or cross-domain network security management appliance, platform and system, and remote management method and system therefor

Abstract

Described are various embodiments of an integrated multi-level or cross-domain network security appliance and system. In one embodiment, a cross-domain network traffic management appliance comprises: an external hardware network domain port to interface with an external network corresponding with a first network security domain, and exchange domain-specific data therethrough; a cross-domain hardware port to interface with a second network security domain and exchange cross-domain data therethrough; one or more hardware-integrated processing engines; and a hardware-integrated interconnection matrix configured to define, in hardware, designated data communication paths to interconnect said processing engines; wherein said one or more hardware-integrated processing engines are operable to: process and validate ingress first domain data received from said first network security domain via said external hardware port for cross-domain egress via said cross-domain hardware port; and process cross-domain ingress data received via said cross-domain hardware port for dispatch to said first network security domain via said external hardware network port; wherein cross-domain egress and ingress data is internally encrypted and decrypted, respectively, in accordance with a designated destination-domain encryption process.
