Zero Trust is implemented by continuously inspecting and validating traffic, identity, device posture, application access, and behavior. The model does not assume trust based on network location. Instead, every access request should be verified, authorized, and limited to what is necessary. Assigning all security to a proxy solution is too narrow; Zero Trust is an architecture and operating model, not a single product. Designating failover paths improves availability, but it does not implement Zero Trust. Removing excess network devices may simplify infrastructure but does not create continuous validation. In a network context, Zero Trust commonly includes segmentation, least privilege access, strong authentication, application-aware policy, traffic inspection, and continuous monitoring. The goal is to reduce implicit trust and limit the blast radius if a user, device, or workload is compromised. A helpful analogy: Zero Trust is not one locked front door; it is badge checks throughout the building. Reference/topics: Cybersecurity 1.6, Zero Trust; Network Security 3.1 and 3.2.
