Abstract

Zero Trust Architecture (ZTA) is a modern cybersecurity model that shifts away from traditional perimeter-based defences. It operates on the principle of “never trust, always verify,” requiring continuous authentication and strict access control for all users and devices. This research examines the effectiveness of ZTA in securing enterprise networks, particularly against risks linked to cloud computing, remote work, and advanced cyber threats. The study analyses case examples to assess how ZTA mitigates unauthorized access, lateral movement, and credential misuse. It also highlights implementation challenges such as integration with existing systems and increased complexity. Despite these issues, findings indicate that ZTA enhances overall security and aligns well with evolving cybersecurity standards.
