Check Text ( C-12939r2_chk )
Review all network element configurations to ensure that an authentication server is being used. Then verify that a two-factor authentication method has been implemented. The RADIUS or TACACS server referenced in the configurations will call a two-factor authentication server.

If two-factor authentication is not being used to access all network elements, this is a finding.
