Zero-Trust Cloud Security Architectures with AI-Orchestrated Policy Enforcement for U.S. Critical Sectors

Open access
·2025·International Journal of Science and Engineering Applications

Abstract

As U.S. critical sectors such as finance, healthcare, and defense accelerate their transition into cloud-native infrastructures, the need for robust and adaptive cybersecurity frameworks has become a matter of national urgency.Traditional perimeter-based models have proven insufficient against sophisticated cyberattacks, particularly supply chain compromises exemplified by SolarWinds, which exploit trusted channels to bypass conventional defenses.Addressing this challenge requires a paradigm shift toward zero-trust principles, where continuous authentication, contextual verification, and strict least-privilege policies are fundamental to ensuring system integrity.This paper proposes a zero-trust cloud security architecture enhanced by AI-orchestrated policy enforcement and microsegmentation to safeguard high-value assets in critical infrastructure.At a broad level, the framework combines identity-centric security with automated decision-making models that continuously monitor user behavior, system activity, and network flows.AI-driven orchestration enables real-time privilege adjustments, proactive anomaly detection, and automated policy enforcement across distributed cloud environments.By embedding intelligence into access and workload controls, the system not only prevents lateral movement by malicious actors but also adapts dynamically to evolving threat landscapes.Focusing on application within the U.S. context, this work demonstrates how the architecture supports resilience against insider threats, ransomware, and supply chain attacks targeting essential services.The framework establishes a scalable, national-security-grade model capable of supporting compliance with federal cybersecurity mandates while maintaining operational efficiency.Narrowing the scope, the study underscores that the integration of zero-trust and AI is not merely a technical upgrade but a strategic necessity for securing critical infrastructures that underpin national stability.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
