Before implementing changes in a production environment, what should entities do when feasible?

Testing changes in a test environment before implementing them in a production environment is crucial for ensuring the stability and security of critical infrastructure systems. This practice allows entities to identify and resolve potential issues, assess the impact of the changes, and verify that everything functions as intended without risking the integrity of the production environment.

A test environment mimics the production setup, enabling entities to conduct various tests that help in understanding how changes will affect system performance and security. By doing so, organizations can prevent disruptions or failures that could arise from untested changes, which is particularly important in a sector as sensitive as critical infrastructure where continuity and reliability are paramount.

This approach aligns with NERC CIP standards, which emphasize risk management and robust change management processes. It helps ensure that all changes are thoroughly vetted and that any unforeseen complications can be addressed before public-facing systems are altered.
