A Case Study: Leveraging SASE Technology for Zero Trust Implementation in Cloud Environments
J. Lee, Jungsoo Park · 2025
Recently, the changes in the cybersecurity environment and the proliferation of cloud-based services have highlighted the limitations of traditional security models. Zero Trust (ZT) is a security concept based on the principle of trusting no one. Zero Trust Architecture (ZTA) is a security framework that operates without trusting any device or user, instead requiring authentication and authorization for each request. This concept shares similarities with Secure Access Service Edge (SASE), a framework that integrates multiple network and security functions at the cloud edge, reducing costs and maintenance for organizations implementing their network strategies. Zero Trust is a response to modern enterprise network trends, including remote users, bring your own device (BYOD), and cloud-based assets that exist outside traditional enterprise network boundaries. In this paper, we will analyze SASE within the context of Zero Trust Architecture and recommend an adoption strategy.
