As manufacturers embrace digital transformation, securing operational technology (OT) environments has become more critical than ever. With the convergence of IT and OT, manufacturing systems are increasingly connected to the cloud, creating new cybersecurity challenges that must be addressed to protect industrial operations.

This guide explores security best practices for safeguarding manufacturing OT environments and ensuring resilient, secure industrial operations:

• Secure network connectivity: Learn how to establish secure connections between manufacturing systems and the cloud using AWS services like AWS Direct Connect, VPN, and PrivateLink.

• Protect local and cloud-connected resources: Implement identity and access management controls, firewall protections, and encrypted communication to safeguard OT systems.

• Enhance monitoring and threat detection: Utilise AWS security tools to continuously monitor industrial networks, detect anomalies, and prevent unauthorised access.

• Strengthen data security: Encrypt manufacturing data at rest and in transit, apply access controls, and ensure data integrity across distributed environments.

• Implement Zero Trust principles: Reduce reliance on perimeter security by adopting Zero Trust architecture, enforcing least privilege access, and verifying all network communications.

• Ensure compliance and risk management: Align OT security with industry standards such as NIST, IEC 62443, and AWS Well-Architected security frameworks.

By adopting these security best practices, manufacturers can build a resilient cybersecurity strategy that protects their industrial assets, minimises risks, and ensures continuous operations. Download the guide to learn how AWS can help secure manufacturing OT environments.
