Whom should I inform about the current issue with the default certificates in WinCC OA?

  • Everyone responsible for the operation, the security or the engineering of a project.
  • System Integrators?
    Yes. Even if they are no longer responsible for certain projects.
    They should be aware that they should create project specific certificates in every – especially new – projects and not use the provided default ones, espcially not in production.
  • End customers?
    Yes, as well. Eventually they are responsible for the security of their operations.
    By using our default certificates - which are mainly provided for convenience and to increase security after installation - the level of security is diminished.
