ISO 62443

The Standard for Industrial Automation

What is ISO 62443?

The international standard ISO 62443 is currently in the publishing process. Although it is not formally part of the ISO 27000 series of standards, it is closely linked to it as far as content is concerned: ISO 62443's objective is to define technical security requirements for communication scenarios within automation systems. Accordingly, it may be regarded as an industry-specific version of the ISO 27001 standard.

With ISO 62443, companies will be given the opportunity to establish a required minimum of information security within the field of industrial automation, in order to ensure the confidentiality, availability, and integrity of the data processed.

Threats and Vulnerabilities Specific to Industrial Automation

Production facilities for manufacturing companies are often coupled with corporate IT systems for fast and effective supply of materials and order processing. The IT systems in turn connect manufacturers with suppliers and customers, resulting in an increased risk to information security and thus to the availability of corporate IT systems and production facilities. If these systems fail or their performance is reduced, the company's productivity and thus profitability will suffer as well. In addition, the high security requirements of internal data are to be taken into account: especially their confidentiality and integrity must be ensured during transmission and processing.

ISO 62443: Topics and Content

Taking the threats and vulnerabilities specific to industrial automation into account, 62443 defines security profiles for the following scenarios:
  • Communication in the IT network
  • Communication in the automation network
  • Connecting maintenance equipment (PCs) to the automation network
  • Communication between production cells
  • Communications with remote devices
  • Connection to the office network – remote maintenance – communication between control stations
Each security profile defines user scenarios, security threats, security requirements as well as responsibilities.
