A service provider is off-boarding a user.

Off-boarding a user is a critical process that must be handled carefully to ensure that all access rights and privileges are revoked to protect the organization’s data and systems.

Option A (Incorrect):While communication is important, the primary concern during off-boarding is to revoke access.

Option B (Incorrect):Performing a root cause analysis is not relevant to off-boarding unless there was a specific incident that necessitated the off-boarding.

Option C (Incorrect):Ensuring that invoices are paid is more of an administrative task and, while important, is not the key security action in the off-boarding process.

Option D (Correct):Revoking access to the service is the most crucial action to take when off-boarding a user. This ensures that the former user cannot access sensitive information or systems after their departure, which is essential for maintaining security​​.
