HMS Networks Urges ISA/IEC 62443 Adoption for Industrial Network Security
HMS Networks advocates for strengthening industrial network security through ISA/IEC 62443 standards, utilizing zones and conduits to protect critical operations against evolving cyber threats.

HMS Networks is emphasizing the critical need for robust cybersecurity in industrial settings, detailing how the ISA/IEC 62443-3-3 standard, alongside the implementation of zones and conduits, can fortify industrial operations.
As industrial sectors face increasing cyber threats, safeguarding Industrial Control Systems (ICS) and Operational Technology (OT) environments has become paramount. The ISA/IEC 62443 series provides a comprehensive framework for securing industrial automation and control systems (IACS), with the -3-3 part focusing on system security requirements.
The standard outlines key security capabilities, including access control, use control, system integrity, data confidentiality, and restricted data flow. These measures are designed to prevent unauthorized access and data exchange, thereby mitigating risks to operational continuity and business reputation.
Network segmentation, achieved through methods like VLANs or physical isolation, is a core component of the ISA/IEC 62443-3-3 standard. Industrial firewalls act as conduits, enforcing strict communication policies between network zones to enhance access control and overall system integrity, essential for meeting higher security levels.
