AN ADVANCED HYBRID SECURITY FRAMEWORK: ENHANCING ZERO TRUST ARCHITECTURE IN DISTRIBUTED CLOUD ENVIRONMENTS VIA PRIVATE BLOCKCHAIN NETWORKS

Abstract

Modern distributed cloud architectures are highly vulnerable to sophisticated cyber threats due to the inherent limitations of traditional perimeter-based security parameters. This research presents a comprehensive, high-security hybrid framework that natively integrates Zero-Trust Architecture (ZTA) with decentralized Private Blockchain networks. By replacing continuous implicit trust with explicit, cryptographic, and dynamic validation parameters, this model ensures that every user, node, and micro-transaction is verifiedin real-time. The deployment of decentralized smart contracts prevents single-point-of-failure vulnerabilities, minimizes lateral threatmovements, and guarantees immutable synchronization of administrative audit trails.
