[All CMMC-CCA Questions]

During an assessment, the IT security engineers responsible for password policy for the OSC provided documentation that all passwords are protected using a one-way hashing methodology. As a result, which statement is true?

Show Suggested Answer Hide Answer
Suggested Answer: D

A one-way hash function is a cryptographic method used to store passwords securely. It is not reversible; hashed values cannot be converted back into the original password.

Extract from SC.L2-3.13.10:

''Store and transmit authentication information in a protected form by using one-way cryptographic transformations (e.g., hashing). One-way transformations cannot be reversed to reveal the original authentication secret.''

Thus, the correct statement is that the transformation makes it impossible to re-convert the hashed password.

I think D is true. Hashing can't be reversed.

I think option C is misleading because hashing doesn't provide access; it just protects the password itself. So I lean towards D being the right answer.

I feel like I've seen a question like this before, and it was about how hashing protects passwords, but it doesn't necessarily mean they're safe in transit.

I'm not entirely sure, but I think hashed passwords are still vulnerable during transmission unless they're encrypted. So A might not be true?

I remember discussing how one-way hashing means you can't easily revert to the original password, so maybe D is correct?
