Spotlight: Security Development Lifecycle (SDL)

For Selectron, cybersecurity is a basic technology that enables modern automation systems and future intelligent technologies, such as self-driving trains. Therefore, the implementation of a Security Development Lifecycle (SDL) in our development processes is essential. The SDL defines steps to incorporate cybersecurity into the development and maintenance of products. This requires adjustments in all aspects of the development process, from the design and concept through to implementation and testing of the products; maintenance of the products is particularly influenced. Continuous observation of the products for possible weak points – and dealing with these problems – is necessary to ensure cybersecurity.

Last but not least, a defined process is necessary to certify products according to the IEC 62443 standard. The Cyber Security Department at Selectron has worked out the necessary adaptations in cooperation with TÜV Rheinland. The final adaptations are currently being carried out, so that future products from Selectron will be Cybersecure by Design.

The secure development process developed at Selectron also serves as a template for the Knorr-Bremse Group. As the Center of Competence for cybersecurity within the Knorr-Bremse Group, Selectron is leading the way in this area.
