Abstract

PT Global Solusindo Kompudata's simple network infrastructure is vulnerable to unauthorized access and decreased productivity due to the lack of VLAN segmentation and firewall. This study aims to design a network security system using VLAN and Layer-7 firewall based on MikroTik for traffic isolation and access restrictions on unproductive sites. This type of development research (R&D) with a mixed methods approach using GNS3 simulation. The population of the entire new building network (93 devices); purposive samples of MikroTik routers, Cisco switches, and specific VLANs. Winbox, GNS3, and Layer 7 analyzer instruments; qualitative-quantitative descriptive analysis with triangulation. The results show that VLAN 10-40 isolates inter-segment communication and the firewall blocks YouTube on VLAN 20-30, with CPU utilization dropping by 30-40%. The design is effective for SMEs, physical implementation with advanced QoS testing is recommended.
