Zorluk: KolayData Destruction and Disposal Methods

A security technician is preparing to decommission server rack disk arrays containing retired magnetic Hard Disk Drives (HDDs) that stored unencrypted sensitive employee data. According to organizational security policy and CompTIA A+ guidelines, which TWO of the following sanitization and disposal methods are appropriate for destroying the data on these magnetic HDDs? (Select TWO.)

  1. Exposing the magnetic hard drives to a high-density electromagnetic field generator (degaussing)Cevap
  2. B
    Performing a standard high-level format using operating system disk management utility tools
  3. Passing the magnetic disk units through an industrial physical drive shredderCevap
  4. D
    Initializing a low-level format using standard factory setup software commands without physical destruction

Cevap

The correct procedures are degaussing the magnetic hard drives using a high-density electromagnetic field generator and physically destroying the drives using an industrial drive shredder.
For magnetic hard disk drives (HDDs), both degaussing (exposing magnetic platters to strong electromagnetic fields) and physical destruction (such as industrial drive shredding) ensure that confidential data cannot be retrieved forensically.

Adım Adım Çözüm

1
Identify the media type and compliance sensitivity level.
The target media consists of magnetic Hard Disk Drives (HDDs) containing sensitive unencrypted corporate employee records.
Selecting the correct disposal method requires matching media physical construction (magnetic vs. flash memory) to required security thresholds.
2
Evaluate degaussing as a destruction method.
Degaussing neutralizes magnetic domains on disk platters, effectively rendering magnetic media blank and unreadable.
Degaussing is an industry-standard method for sanitizing magnetic media prior to disposal.
3
Evaluate physical shredding as a destruction method.
Industrial mechanical shredding destroys physical platters completely.
Physical destruction prevents any possibility of drive re-use or forensic data extraction.
