PR.DS-7.1
PR.DS-7.1: The development and test environment(s) shall be isolated from the production environment.
  • Any change one wants to make to the ICT/OT environment should first be tested in an environment that is different and separate from the production environment (operational environment) before that change is effectively implemented . That way, the effect of those changes can be analysed and adjustments can be made without disrupting operational activities.
  • Consider adding and testing cybersecurity features as early as during development (secure development lifecycle principles).
