The operating system is based fundamentally around a protocol stack (e.g., TCP/IP stack), rather than including a transport/network layer in a conventional core operating system. The firewall security device may include a processor and an operating system (OS) embedded in the processor. The OS may include a kernel. The operating system kernel is a state machine and may include a protocol stack for communicating with one or more devices via a network interface. The OS may be configured to receive and transmit data packets and block unauthorized data packets within one or more layers of the protocol stack based on predetermined firewall policies."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultra-small, ultra-low power single-chip firewall security device with tightly-coupled software and hardware","description":"A firewall security device, system and corresponding method are provided that includes an operating system of an entirely new architecture.
