NISTNIST CSFProtect FunctionEASYFree question
What is multi-factor authentication (MFA) and why does the Protect function emphasize it?
- A.Using multiple passwords for the same account
- B.Authenticating with multiple biometric scans of the same type
- C.Having multiple users authenticate the same request
- D.Authentication requiring two or more factors (something you know, have, or are), significantly reducing the risk of unauthorized access even when one factor is compromised
Why D is correct
MFA combines different authentication factors (password + token, biometric + smart card), making it much harder for attackers to gain access even with stolen credentials.
