IEC 62443
Security for your industrial automation
Protect your OT systems against cyber threats – compliant with standards, sustainable, and practice-oriented.
Key Facts at a Glance
The IEC 62443 standards series is the international standard for the cybersecurity of Industrial Automation and Control Systems (IACS).
It is aimed at operators, integrators, manufacturers, and service providers and describes measures to systematically identify, minimize, and continuously monitor cyber risks in industrial environments.
The goal is to ensure the availability, integrity, and confidentiality of industrial systems – thereby preventing production downtime, data loss, or manipulation.
Imagine your industrial plant as a city:
- Streets and roads = your networks
- Buildings = your control systems and machines
- Inhabitants = your processes and data
IEC 62443 ensures that only authorized persons gain access, threats are detected early, and damage is prevented.
The standard is divided into several parts – from general requirements to specific provisions for manufacturers, integrators, and operators.
What makes it special: IEC 62443 combines technical security measures (firewalls, access control, network segmentation) with organizational requirements (roles, processes, risk management).
This is how the implementation of this standard works
Implementation takes place step by step:
-
Analysis and Classification
- Recording existing systems (Asset Inventory)
- Assessment of cyber risks (Risk Assessment)
- Definition of security zones and conduits
-
Definition of the Security Level
- Determination of the required Security Level (SL 1–4)
- Alignment with the requirements of IEC 62443
-
Technical & Organizational Measures
- Network segmentation, firewalls, access controls
- Secure software updates and patch management
- Emergency and incident response plans
-
Review & Continuous Improvement
- Regular audits and penetration tests
- Adjustment of measures to new threats
- Employee training
