COVER STORY
ENHANCING INDUSTRIAL CYBERSECURITY WITH FLEXEDGE® Powered by Crimson®, Aligned with ISA/IEC 62443 Standards
Cybersecurity is a growing concern in industrial environments, where alignment with ISA/IEC 62443 standards is critical. A whitepaper from Red Lion explores how its FlexEdge, powered by Crimson 3.2, helps organisations meet these standards through key countermeasures, including logical access controls, data flow management, data integrity, policy enforcement, and system hardening

lexEdge, with its robust Crimson 3.2 software, offers tailored security features for industrial applications, such as secure login, role-based access, and remote authentication, aligning with logical access control requirements. It includes advanced data flow controls like VLANs and firewalls to manage network segmentation and secure data transmission. Data integrity is maintained through encryption and VPN support, safeguarding information from unauthorised access and modification. Controls engineers can align with IT policies like password expiration, ensuring consistent security practices across the network. Additionally, FlexEdge allows administrators to disable unused ports and services, reducing potential vulnerabilities.

By leveraging these features, organisations can align their industrial applications with ISA/IEC 62443, enhancing their cybersecurity posture against evolving threats.
INTRODUCTION TO ISA/IEC 62443 ISA/IEC 62443 is a series of standards that secure Industrial Automation and Control Systems (IACS) throughout their lifecycle, from design to decommissioning. What sets ISA/IEC 62443 apart is its adaptation of IT cybersecurity practices to industrial environments.
Key concepts include: • Principle of Least Access: Restricting user and device permissions to the minimum necessary, reducing potential damage from breaches. • Defence in Depth: Implementing multiple
layers of security controls, such as firewalls, encryption, and access controls, to protect critical assets even if one layer is compromised. • Zones and Conduits: Segmenting the network into secure zones with conduits controlling data flow between them, protecting sensitive data and limiting the spread of potential breaches. Red Lion’s FlexEdge supports these concepts, providing the necessary tools to implement a robust, ISA/IEC 62443-aligned cybersecurity posture.
