A company requires employees to enter a password and then a one-time code sent to their mobile phone before accessing the ERP system. This is an example of which security measure?

This is multi-factor authentication. The user must give two distinct proofs of identity, a password they know and a one-time code on a device they hold. This reduces the risk from stolen passwords, unlike masking, address translation or load balancing.

  3. CNetwork address translation
  4. DLoad balancing

Explanation

Using two different types of proof, something known (password) and something possessed (phone code), is multi-factor authentication. Data masking hides sensitive values, NAT maps network addresses, and load balancing spreads traffic; none verify user identity in this way.
