Abstract

To counteract the evolved threat landscape and the inadequacies of boundary-centric protection, here we present a multi-tiered AI-based Zero Trust Architecture (ZTA) model designed specifically for the hybrid, legacy, and contemporary IT ecosystems. In contrast to current methods that focus on either conceptual models only, or operate within a single domain, the proposed approach unifies identity, device, network, and application-level security through the application of real-time threat intelligence and adaptive policy enforcement. Using XAI and automation, the architecture automatically adapts access controls through contextual risk analysis, user activity and operational requirements. Cross-domain validation, migration patterns for legacy systems and industry-specific deployments are included in the study, making its reach very broad. Performance monitoring and dashboard builds are implemented to improve transparency, scalability and operational efficiency. In doing so, this paper, not only fills the existing void in Zero Trust research, but is also prescriptive, offering an actionable plan for how enterprises can exercise both continuous verification and least-privilege access to heterogeneous and dynamic environments.
