Security Guidelines

OMRON provides security guidelines to help customers apply appropriate cybersecurity measures for industrial automation systems, controllers, software, and related components.

These resources include recommended practices for secure configuration, system design, operation, maintenance, and risk reduction in industrial environments.

Why this matters: Industrial automation environments often include connected systems, networks, software, and operational technology assets. Applying appropriate security measures can help reduce cybersecurity risk and support secure, reliable operations.

Industrial Security Guidance

Industrial automation environments often include both information technology and operational technology systems. Security measures should be planned and implemented with consideration for system availability, safety, network architecture, access control, and maintenance requirements.

OMRON security guidelines are intended to support customers in applying appropriate protective measures throughout the product lifecycle.

Recommended Security Practices

Customers should consider the following practices when designing, operating, and maintaining industrial automation systems:

• Follow applicable laws, standards, and organizational security policies

• Segment industrial networks from business and external networks

• Limit access to authorized users only

• Apply strong authentication and access control policies

• Keep software, firmware, and security patches up to date

• Review product documentation and security advisories regularly

• Disable unused services, ports, or communication paths where appropriate

• Monitor systems for unexpected activity

• Maintain secure backup and recovery procedures

Implementation note: Security requirements may vary depending on system configuration, network environment, applicable regulations, and operational requirements. Customers are responsible for evaluating and implementing security measures appropriate for their specific environment.
