An organization is retiring a customer relationship management system that stored personally identifiable information. The system is scheduled for shutdown in 30 days, and the ISSMP must ensure the decommissioning aligns with lifecycle management and data protection obligations. Which action should the ISSMP prioritize?
Personal data often persists in backups, replicas, analytics extracts, and test copies that are easy to overlook. A data inventory ensures every location is identified before disposal, and applying the retention schedule determines what must be destroyed versus lawfully retained. Verified destruction with certification produces evidence of compliance, which is essential when regulators or auditors request proof of proper decommissioning.
Why this answer
Decommissioning must account for personal data wherever it resides, not just in the production database. A full inventory identifies backups, replicas, and derived datasets, and the retention schedule determines what may be kept lawfully. Verified destruction with certification gives the organization defensible evidence that privacy obligations were met, closing the lifecycle properly rather than leaving orphaned copies behind.
Exam trap
The trap here is assuming that deleting the production database completes the decommissioning when backups, replicas, and derived datasets still hold the same personal data.
