01Define the boundary
Identify the actor, target resource and operation that impersonation is meant to govern.
02Configure the policy
Define who may impersonate whom, what actions are blocked, how the target identity is displayed, when sessions expire and which events must be recorded. Preserve explicit exclusions for administrator accounts and protected employee identities where applicable.
03Exercise the edge cases
Support opens an approved customer context to reproduce a problem, then exits the session with an auditable record of the operator and target. Also test the path that should be denied, deferred or sent for review.
04Review the outcome
Check that the resulting state is understandable and that the decision can be investigated later. For audit-enabled operations, confirm the relevant actor and context are captured.
