Implementing Zero Trust Architecture across Multi-Cloud Environments: A Security Framework

Abstract

The rise of multi-cloud environments has introduced new complexities in securing distributed systems. Traditional perimeter-based security models no longer suffice, necessitating the adoption of Zero Trust Architecture (ZTA). Zero Trust enforces strict access controls based on identity, device posture, and continuous verification, irrespective of network location. This paper presents a detailed framework for implementing Zero Trust Architecture across multi-cloud environments. It outlines the architectural components, technologies, challenges, and best practices to ensure robust security.
