The firewall implementation must use multifactor authentication for local access to privileged accounts.

Description
Single factor authentication poses unnecessary risk to the information system since most single factor authentication methods use only a userid and password. Passwords are, in most cases, easily hacked with the right tools. Multifactor authentication utilizes multiple levels of identification and authorization criteria and provides a much stronger level of security than single factor. As privileged users have access to most of the files on the platform, using a single factor authentication approach provides an easy avenue of attack for a malicious user. Factors include: (i) something you know (e.g., password/PIN); (ii) something you have (e.g., cryptographic identification device, token); or (iii) something you are (e.g., biometric).

Check Text ( C-SRG-NET-000141-FW-000086_chk )
If authentication functionality is provided by the underlying platform's account management system or by a network authentication server rather than the firewall application itself, this is not a finding. Verify the configuration for the firewall requires access using a multifactor authentication mechanism (e.g., PKI, SecureID, or DoD Alternate Token). If multifactor authentication is not used for local access to privileged accounts, this is a finding.

Configure local access to privileged accounts to use multifactor authentication (e.g., PKI, SecureID, or DoD Alternate Token).
