Comprehensive Security Solution for an Industry 4.0 Garment Manufacturing System

Industry 4.0, digital transformation towards Internet of Things (IoT) focuses on productivity rather than security, therefore often face cybersecurity challenges. To overcome such, a centralized security solution focusing on four major areas 1) Standardization, 2) Security configurations with update management, 3) Authentication and physical access control and 4) Intrusion detection was applied to Cyber Physical System (CPS) based garment manufacturing system to overcome the security gap. Security policies based on ISO 27001:2013 and IEC 62443 security standards were applied to the security configuration management system in the design stage to achieve ‘security by design’ concept. Security and audit configurations were applied using Ansible for the automated tool that can be customized based on requirements. A Raspberry Pi 4 was utilized as IDS (Intrusion Detection System) to evaluate performance. The physical access control prevents unauthorized access and access monitoring was done using logs. The proposed system enhances security, reaching for a cost-effective, efficient, reusable solution, and provides a comprehensive security solution for potential challenges of current and future smart manufacturing. The system is secured in terms of strategy, design, and operations rather than securing the system after deployment.
