A Comprehensive Framework for Migrating to Zero Trust Architecture

Migrating to Zero Trust Architecture (ZTA) is a strategic approach to strengthen the enterprise's security postures. The shift to ZTA requires changes across the enterprise which can be challenging to achieve. Utilizing an effective framework for migrating from the old security architecture to ZTA can help ensure smooth transitioning to the Zero Trust journey. In previous research, the effective frameworks and processes for migrating to ZTA have not been achieved in an integrated and comprehensive manner. This study introduces a comprehensive framework for migrating to ZTA. The methodology of this study is to analyze and synthesize published studies relating to ZTA migration. The findings from existing knowledge construct a process-driven for the ZTA migration. In addition, the study addresses migration challenges and gaps in existing ZTA migration approaches. As a result, a comprehensive Zero Trust migration framework is developed to construct streamlined processes. The proposed framework can be used as a reference model for effective transitioning to ZTA.
