Exam CISSP topic 1 question 14 discussion

I agree with given answer here "C" Degaussing - once a drive has been degaussed, it can no longer be used. Single Pass - replacing 0s and 1s might not be enough. With the right tools "in theory" some of the data can be recover Muti-Pass - Gives us that "peace of mind" the data has been permanetly deleted.

Degaussing is the best option if we are no longer using the drive but since the question i asking "reuse program" therefore C is the best option here.

Degaussing

From the official study guide: Degaussing a hard disk will normally destroy the electronics used to access the data. However, you won’t have any assurance that all the data on the disk has actually been destroyed. Someone could open the drive in a clean room and install the platters on a different drive to read the data. Purging is a more intense form of clearing that prepares media for reuse in less secure environments. It provides a level of assurance that the original data is not recoverable using any known methods. A purging process will repeat the clearing process multiple times and may combine it with another method, such as degaussing, to completely remove the data.

Degaussing basically disabled the drive

D, most secure and the company still get the money

Multi Pass might work for HDD.. but SSD and others does not... for More Money, and IT Security Professional would rather get the money that it takes but keep data safe, therefore Degaussing should always be the answer. Answer D.

The most secure method of data sanitization in this scenario would typically be: D. Degaussing Degaussing involves exposing magnetic storage media to a strong magnetic field to completely erase the data. It's highly secure but renders the drives unusable for data storage. While multi-pass wipes (Option C) can also provide a high level of data sanitization, they may still leave traces of data on the drive, which might be recoverable with specialized techniques

I agree with given answer here "C". Because Question has a limit "The vendor pays more money for functioning drives than equipment that is no longer operational". Degaussing make it can not be used, vendor must magnetizing before reuse. Otherwise I will choose D.

Answer is C

degaussing, which uses a powerful magnetic field to erase data. Degaussing is generally considered the most secure form of data erasure, as it is impossible to recover any data once it has been degaussed.

C- Multi-pass wipes = data sanitization that involves writing over the data on a hard drive multiple times using a specific pattern of data.

Agreed, C

C is correct answer. Multi-pass. The question did not state what type of disks were present so cannot assume spinning disks only. As per other correct answers, degaussing would render disks unusable.

But what about the storage device, itself? One of the biggest questions users have after degaussing their hard drive is can a degaussed hard drive be reused? No, they cannot. Once a hard drive or other storage device has been exposed to the degaussing process, the alterations made to the magnetic field will prevent the read heads from ever finding a magnetic reference point. Degaussing a drive irreversibly changes the device’s makeup so the drive can never again be used, let alone read.
