Difficulty: MediumData Destruction and Disposal Methods

A logistics company is upgrading its data center and must decommission retired storage assets, including magnetic backup tapes and solid-state drives (SSDs). The security policy mandates a single physical destruction method that renders both media types completely unusable and unrecoverable. Which of the following disposal methods fulfills this requirement?

  1. A
    Degaussing the assets using a high-powered electromagnetic field generator
  2. Shredding the assets using an industrial mechanical shredderAnswer
  3. C
    Performing a full low-level format on all storage volumes
  4. D
    Initiating a cryptographic erase operation across all drives

Answer

Shredding the assets using an industrial mechanical shredder
Shredding (or physical disintegration) physically breaks the storage substrate—both magnetic tape ribbons and SSD flash memory chips—into tiny fragments, preventing any data recovery across all media types.

Step-by-Step Solution

1
Analyze the storage media types mentioned in the scenario.
The assets consist of both magnetic media (backup tapes) and flash-based solid-state media (SSDs).
Different storage technologies react differently to sanitization and destruction methods.
2
Evaluate the effectiveness of candidate physical destruction methods against both media types.
Degaussing neutralizes magnetic tape but does not destroy solid-state flash memory chips. Physical shredding physically cuts both magnetic tapes and SSD circuit boards into tiny fragments.
A single physical destruction process must be chosen that effectively destroys both magnetic and semiconductor storage mechanisms.
3
Select the disposal method that satisfies the physical destruction mandate.
Shredding guarantees complete physical destruction and unrecoverability for both SSDs and magnetic tapes.
Industrial shredding/disintegration is recognized by security standards as an effective physical destruction method for mixed media.
