A technician is decommissioning a server from a production environment. The technician removes the server from the rack but then decides to repurpose the system as a lab server instead of decommissioning it. Which of the following is the most appropriate NEXT step to recycle and reuse the system drives?

When a server is moved from a production environment, it is critical to ensure that all sensitive production data is securely and permanently removed before the hardware is repurposed. Wiping the drives, also known as clearing or sanitization, is the process of overwriting all data on the storage media. This method effectively erases the previous data, preventing its recovery through software-based tools, while keeping the drive physically intact and ready for reuse in the new lab environment. This step is essential for data security and to provide a clean slate for the server's new role.

A. Reinstall the OS: Simply reinstalling the operating system is not a secure method of data removal, as it may leave data remnants on the drive that could be recovered.
C. Degauss the drives: Degaussing uses a powerful magnetic field to destroy data on magnetic hard drives, but it also destroys the drive's firmware, rendering it permanently unusable.
D. Update the IP schema: This is a network configuration task that would be performed after the server has been properly sanitized, a new OS installed, and placed into the lab network.

1. NIST Special Publication 800-88 Revision 1

"Guidelines for Media Sanitization": This publication defines the methods for data destruction.

Section 2.3

"Clear": Describes the process of using logical techniques to sanitize data

such as overwriting. It states

"Clear is a level of media sanitization that would protect the confidentiality of information against a robust keyboard attack." This method allows for the media to be reused.

Appendix A

Table A-1

"Hard Copy Storage Devices Sanitization": For Hard Disk Drives (HDDs)

it specifies that degaussing renders the drive "inoperable" because it erases the servo tracks. This confirms that degaussing is a destructive method unsuitable for reuse.

Berkeley

"Data Sanitization Methods": Courseware and security guidelines often reference NIST standards for proper data handling.

"Secure Deletion of Data": The Berkeley Security policy outlines that for devices being repurposed within the organization

a "full format" or "drive wipe" is required. It distinguishes this from methods used for disposal

such as physical destruction or degaussing

which are reserved for media that will not be reused. (Reference: UC Berkeley Information Security Office
