Abstract

In an increasingly complex digital era, government agencies such as the Communication and Information Service (Diskominfo) of Central Lombok Regency face serious challenges related to network security. This research aims to design and implement a Fortinet FortiGate firewall-based network security system, in order to detect and address cyber threats that have the potential to disrupt operations and public services. The method used is the Network Development Life Cycle (NDLC), which includes the stages of analysis, design, simulation, implementation, monitoring, and management. The system was tested using common attack scenarios such as PortSscanning and Denial of Service (DoS) with the help of tools such as nmap, sqlmap and hping3. The results show that the implementation of FortiGate, including features such as Web Application Firewall (WAF), Intrusion Prevention System (IPS) and Antivirus, is able to provide comprehensive protection and real-time response to threats. This study also shows that the Fortigate-based network security system is able to significantly improve the network security posture of the Communication and Information Service (Diskominfo) of Central Lombok Regency. This system provides multi-layered, reliable, and easy-to-manage protection, and is an important foundation in maintaining the sustainability of local government digital services.
