ISC2 Governance, Risk and Compliance (CGRC) Practice Question
An organization is decommissioning a storage array that previously hosted sensitive customer records. Policy permits donating hardware only after data is rendered unrecoverable while preserving the asset's market value. Which disposal action should be performed to meet the policy requirement before the array leaves organizational control?
Execute a cryptographic erase of all disk volumes and verify purge results.
Power down the array and remove the disks before shipment to the donor.
Physically shred each hard disk in an approved destruction facility.
Degauss all Cat-6 network cables connected to the storage array.
To preserve the equipment and comply with policy, the drives must be sanitized so that no residual data remains yet the hardware remains functional. A cryptographic erase followed by verification meets NIST SP 800-88 purge requirements, rendering data unrecoverable without physically damaging the disks. Physically shredding or removing disks destroys reuse value, while degaussing network cables or simply powering off provides no assurance that data is unrecoverable.
