Optimalisasi Keamanan Jaringan Di Era Digital menggunakan metode Zero Trust

In the digital era, computer networks serve as a crucial foundation for various aspects of life, including business and education. Network security, encompassing data confidentiality, integrity, and availability, is a critical factor in protecting against cyber threats. Universitas Internasional Batam (UIB) faces challenges such as intrusion and hacking, necessitating additional security measures. To address these challenges, the implementation of Zero Trust Network Access (ZTNA) supported by Virtual Private Network (VPN) and Multi-Factor Authentication (MFA) has become a highly relevant strategy. ZTNA ensures that every request for network access is evaluated individually, without assuming trust in any entity, thereby enhancing the necessary security layers. This study employs the Network Development Life Cycle (NDLC) method to design and develop a ZTNA network at UIB using the ZeroTier platform. The process includes network and security requirements analysis, ZTNA architecture design, implementation across various devices, and MFA integration with Google Authenticator. Monitoring and Quality of Service (QoS) testing using iPerf were also conducted to ensure the system's effectiveness. The research findings demonstrate that ZeroTier effectively facilitates direct communication with high-quality service, while the enhanced security provided by MFA makes it a reliable and secure solution for the exchange of sensitive data in the dynamic and complex environment of the university.
