Analisis Dan Implementasi Sistem Firewall dan Intrusion Detection System Menggunakan Metode NDLC Pada Jaringan Perumahan Pamulang Village

Abstract

Network security is essential for protecting network resources from cyber threats. This study aims to analyze and implement a network security system using a Mikrotik Firewall and Snort-based Intrusion Detection System (IDS) following the Network Development Life Cycle (NDLC) method in the Pamulang Village residential network. The implemented system integrates Mikrotik as the Firewall, Snort as the IDS, Python for processing detection logs, MySQL as the database, and a PHP-based Web application for real-time monitoring. System evaluation was conducted through Black Box Testing, White Box Testing, and attack simulations including Port Scanning, ICMP Flood, and TCP Flood. The results show that Snort successfully detected all tested attacks, while the Mikrotik Firewall enforced the configured security rules to mitigate unauthorized access attempts. In addition, the Web-based monitoring application displayed attack logs in real time, enabling Administrators to monitor network security more effectively. The implementation demonstrates that the proposed system improves monitoring capability and supports network security management in the research environment.
