This Arista white paper outlines a Zero Trust Security framework for cloud networking, aligned with NIST 800-207. It replaces implicit trust with continuous monitoring, segmentation, and enforcement across campus, data center, IoT, and cloud environments. Core pillars include situational awareness—using CloudVision and Awake Security to profile endpoints and flows; granular segmentation with Macro-Segmentation Services (MSS) to limit lateral movement; and AI-driven detection with Awake’s Nucleus and Ava for automated threat hunting. DANZ Monitoring Fabric provides pervasive visibility, while Awake’s MNDR service supports incident response. Together, these capabilities enable resilient, breach-assumed defense.
