Siemens gains a TÜV SÜD-certified development process based on IEC 62443-4-1

30 August 2016

The international series of standards IEC 62443 defines the security measures for industrial automation systems, with Part 4-1 of the standard describing the requirements of the manufacturer's development process.

The TÜV SÜD certificate is based on the standard IEC 62443-4-1 (Secure Product Development Lifecycle Requirements, Draft 3 Edition 10, 01.2016). This standard includes security-relevant requirements such as capabilities and expertise, security of third-party components, process and quality assurance, secure architecture and design, and issue handling as well as security updates, patches and change management.

Among other things, the sites to have gained certification are developing Simatic S7 industrial controllers, Simatic industrial PCs, Simatic HMI devices for operator control and monitoring, and Sinamics drives as well as the TIA (Totally Integrated Automation) Portal engineering software.

With this achievement, the company is documenting its ‘Security by Design’ approach for automation products and is giving integrators and operators a transparency into the IT security measures. Integrators and operators use this for the conception and operation of automation processes and systems using Siemens technology and the ‘Defense in Depth’ protection concept.
