Zorluk: ZorData Destruction and Disposal Methods

An IT technician is tasked with decommissioning a batch of enterprise magnetic hard disk drives (HDDs) containing sensitive corporate financial data. Place the administrative and technical steps in the correct chronological order from first to last to ensure compliance with data sanitization standards and chain of custody guidelines.

  1. 1Log drive serial numbers into the asset management database and complete a formal chain-of-custody transfer form.
  2. 2Expose the magnetic hard drives to a high-density degaussing field to purge all magnetic storage domains.
  3. 3Transport the sanitized drives to an off-site physical destruction facility using a secure, tracked courier service.
  4. 4Perform physical industrial shredding of the drives and obtain a signed Certificate of Destruction.
  5. 5Update the asset tracking system to record destroyed status and archive the Certificate of Destruction for audit compliance.

Cevap

The correct chronological sequence is: 1) Log drive serial numbers and complete chain-of-custody forms, 2) Expose magnetic hard drives to high-density degaussing, 3) Transport sanitized drives via secure courier, 4) Perform physical industrial shredding and obtain a Certificate of Destruction, and 5) Update asset records and archive the Certificate of Destruction.
The proper decommission lifecycle requires logging serial numbers to establish chain of custody first, purging magnetic media via degaussing to prevent data exposure in transit, transporting the media securely under custody, executing physical destruction while securing a Certificate of Destruction, and finally closing asset records in the tracking system with attached validation certificates.

Adım Adım Çözüm

1
Establish inventory baseline and documentation.
All drive serial numbers are cataloged with initial chain of custody established.
Proper inventory accounting before physical movement prevents lost or stolen media.
2
Perform local data purge via degaussing.
Magnetic fields on drive platters are completely demagnetized.
Degaussing purges data locally so unencrypted data is not exposed during off-site transportation.
3
Relocate media using tracked chain of custody.
Drives arrive safely at the third-party destruction facility.
Tracked courier services maintain accountability between company premises and vendor facilities.
4
Execute physical destruction and obtain validation.
Drives are shredded into fragments and a Certificate of Destruction is signed.
Physical destruction prevents hardware re-use, and the certificate serves as legal proof of disposal.
5
Finalize corporate inventory logs.
Asset database records drives as destroyed with linked audit documentation.
Completes corporate lifecycle procedures and fulfills compliance audit requirements.
