Exam SY0-501 topic 1 question 733 discussion

Shredding is more secure than deguassing since the actual drives are physically destroyed.

Degaussing : Pros: A degausser is good if you want to completely erase all audio, video and data signals from the magnetic storage. Cons: Degaussing is not entirely fool-proof. It can only be used on magnetic media, and there is no way to guarantee that a particular degaussing machine is strong enough to destroy all the data on every hard drive. Also, degaussing does not provide reporting of the erasure process, which is needed to prove regulatory compliance. Most IT professionals will tell you that degaussing or wiping hard drives is no longer an acceptable method for complete, secure destruction of stored data. ___ Benefits of Hard Drive Shredding: Your sensitive data is now 100% unrecoverable, so you don’t have to worry at all about hackers seizing your data. You can ensure your business is in compliance with regulatory requirements, avoiding fines and potential lawsuits. For personal computers, your data will be safely destroyed without the worry of identity theft ___ We can use degaussing, hard drives are HDD, not SSD, but shredding is better Comparison: https://legalshred.com/degaussing-vs-hard-drive-shredding/

Confidential or secret documents should be marked as such. Such documents may be treated to special disposal methods, such as finer cross-shredding or even incineration. There are several types of shredders. They can be classified to a certain security level, based on the size of the remnants they reduce a sheet to. Level 1 is 12mm strips, while Level 6 is 0.8x4mm particles. If shredding is not considered secure enough, the shredded material can be further subjected to a process of pulping (mixing with water then pulverizing) or burning.

I guess if you can shred HHD- Next best answer after looking at Darril Gibson book would be degaussing - "A degausser is very powerful electronic magnet. Passing disk through field renders the data on tape and magnetic disk drives unreadable'

Which of the following data destruction techniques is MOST appropriate?

I will go with A. I havent seen any information related to Shredding. Here is the explanation: "According to many in the information security field, including the US National Security Agency (NSA), shredding of HDDs is not the best method of destroying information contained in the drive. Degaussing is by far the most common method of sanitizing Top Secret data." According to many in the information security field, including the US National Security Agency (NSA), shredding of HDDs is not the best method of destroying information contained in the drive. ... Degaussing is by far the most common method of sanitizing Top Secret data.

We dont known if the disk is SSD or HDD. You cant degause SSD disks. It wouldnt work. So the answer has to be Shredding.

Other resource: Answer: A Explanation: Hard drive degaussing is a highly advanced technology used to sanitize hard drives before disposal or reuse. Degaussers come in various types and sizes, with varying effectiveness as well. A professional data destruction service selects the most appropriate degausser for the job based on prevailing circumstances. Degaussing is fast and effective, and it ensures that you're compliant with data regulations.

It appears that according to Comptia GCGA book that shredding is never referenced to hard drives it is only referenced for paper. So when taking this specific test, pulverizing is physically destroying drives and shredding is shredding paper. So that answer is A actually from what i can tell...

Degaussing--> Degaussing is not entirely fool-proof. It can only be used on magnetic media, and there is no way to guarantee that a particular degaussing machine is strong enough to destroy all the data on every hard drive. Shredding--> The best and most secure method of rendering hard drive information completely unusable is to completely destroy it through hard drive shredding, your sensitive data is now 100% unrecoverable. So, D. is the correct answer. Reference: https://legalshred.com/degaussing-vs-hard-drive-shredding/

A is the correct answer. Why? the keyword is "data destruction" not hard drives

Pulverize = reduce to fine particles = Shred = destroy

D. https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-88r1.pdf https://datadestruction.com/top-5-hard-drive-destruction-methods-actually-work/

https://legalshred.com/degaussing-vs-hard-drive-shredding/

A is the correct answer. You cannot reuse a hard drive once it has been degaussed. This is because the degaussing process removes all the data and start up files. As such, a degaussed hard drive will not boot up.
