Prior to implementing a design change, the change must go through multiple steps to ensure that it does not cause any security issues. Which of the following is most likely to be one of those steps?

Backout planning is crucial before implementing a design change. It involves creating a detailed plan to revert to the previous stable state if the change introduces unforeseen problems or security vulnerabilities. This minimizes downtime and risk. Board review is a high-level approval process, not a technical step to prevent security issues. Service restart is an action taken during or after implementation, not a planning step to prevent issues. Maintenance refers to ongoing activities after implementation, not a pre-implementation security check.
