INTEGRATION OF AUTOMATION AND NETWORK SECURITY IN INDUSTRIAL IT SYSTEMS: A CASE STUDY AT AGNELO ENGENHARIA (2022–2024)

This article examines the integration of automation processes and network security measures within the IT
infrastructure of Agnelo Engenharia between 2022 and 2024. As the company expanded its internal systems and
digital workload, legacy network models and unsegmented communication paths exposed vulnerabilities in
critical operational environments. Through a structured redesign guided by cybersecurity and automation
principles, the IT department implemented VLAN segmentation, firewall hardening, encrypted remote access,
and enhanced SCADA communication reliability. The study documents the methodology adopted, presents
measurable results, and discusses the interplay between security and automation in industrial IT environments.
