Description
To assure accountability and prevent unauthenticated access, non-privileged users must utilize multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authentication uses two or more factors to achieve authentication. Use of password for user remote access for non-privileged account is not authorized. 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). A non-privileged account is any information system account with authorizations of a non-privileged user. Network access is any access to a network element by a user (or a process acting on behalf of a user) communicating through a network. The DoD CAC with DoD-approved PKI is an example of multifactor authentication.

Check Text (C-239968r954210_chk)

Review the ASA configuration to verify that it enforces certificate-based authentication before granting access to the network as shown in the example below. tunnel-group ANY_CONNECT type remote-access tunnel-group ANY_CONNECT webvpn-attributes authentication certificate If the ASA configuration does not enforce certificate-based authentication before granting access to the network, this is a finding.

Fix Text (F-43160r666309_fix)

Configure the ASA to enforce certificate-based authentication before granting access to the network as shown in the example below. ASA1(config)# tunnel-group ANY_CONNECT webvpn-attributes ASA1(config-tunnel-webvpn)# authentication certificate ASA1(config-tunnel-webvpn)# end
