Implementing Zero Trust Security Models in Cloud Infrastructures

Ayisha Tabbassum, Shaik Abdul Kareem

Abstract: The migration to cloud infrastructures has presented significant security challenges, particularly as traditional perimeter - based security models have proven inadequate for the dynamic and distributed nature of modern cloud environments. This research focuses on the implementation of Zero Trust Security (ZTS) models within cloud infrastructures, with a specific emphasis on Amazon Web Services (AWS). The study outlines the development and application of new frameworks and tools that support ZTS, highlighting their effectiveness in enhancing security posture. Through empirical analysis, the research demonstrates the practical benefits of ZTS in real - world cloud environments, showcasing improvements in threat detection, response times, and overall security management.
