ZERO TRUST ARCHITECTURE WITH SINGLE SIGN ON METHOD ON ENHANCE SECURITY AND USER ACTIVITY MONITORING

The rise of cyberattacks due to weak internet access controls has led to increased data breaches and financial losses. This study proposes the integration of Zero Trust Architecture (ZTA) with Single Sign-On (SSO) to enhance network security while simplifying user authentication and monitoring. ZTA enforces strict verification for each access request, mitigating risks from phishing and brute force attacks. Despite its advantages, ZTA presents challenges, particularly in integrating with legacy systems and managing infrastructure complexity. This research evaluates ZTA implementation through network topology analysis, identity-based access control, segmentation, and Multi-Factor Authentication (MFA) to prevent unauthorized access. The integration of SSO improves authentication efficiency while maintaining security. Authentication performance is a critical factor in ZTA adoption. The results confirm that integrating ZTA with SSO facilitates real-time monitoring, enhances rapid threat response, and improves overall network security, providing a viable cybersecurity solution for modern organizations. Furthermore, this research evaluates authentication response time, aiming for an optimal range of 30-40 MS to ensure system efficiency and security. The study records an authentication time of 30.03 ms, network latency of 29.28 MS, and real-time notifications to IT staff delivered within 2.66 seconds. In live trials with a 200 Mbps bandwidth, the system detected 11 anomalies within 3 hours, demonstrating its effectiveness.
