Physical Hardware Isolation: Enforcing Zero-Trust at the Server Edge
⚡ The Technical Shift: Relocating security enforcement agents, stateful firewalls, and encryption modules (iptables, IPsec, TLS termination) to the DPU's memory space.
🛡️ The Operational Reality: Host root compromises cannot affect the network fabric because the DPU control plane is physically inaccessible via the host operating system.
📐 Architectural Concept: Air-gapped security boundaries established directly on the local server endpoint.
