| Description |
| Without the use of multifactor authentication, the ease of access to privileged functions is greatly increased. Multifactor authentication requires using two or more factors to achieve authentication. Factors include: 1) something a user knows (e.g., password/PIN); 2) something a user has (e.g., cryptographic identification device, token); and 3) something a user is (e.g., biometric). A privileged account is defined as an information system account with authorizations of a privileged user. Network access is defined as access to an information system by a user (or a process acting on behalf of a user) communicating through a network (e.g., local area network, wide area network, or the internet). The DOD CAC with DOD-approved PKI is an example of multifactor authentication. Satisfies: SRG-OS-000105-GPOS-00052, SRG-OS-000106-GPOS-00053, SRG-OS-000107-GPOS-00054, SRG-OS-000108-GPOS-00055 |

Details
| Check Text (C-72060r1039294_chk) |
| Verify NixOS has the packages required for multifactor authentication installed with the following command: $ grep -R pkgs.opencrypto /etc/nixos pkgs.opencryptoki If the "pkgs.opencryptoki" package is not installed, this is a finding. |
| Fix Text (F-71963r1039295_fix) |
| Configure NixOS to have a package that enforces multifactor authentication installed. Add the following Nix code to the NixOS Configuration, usually located in /etc/nixos/configuration.nix: environment.systemPackages = [ pkgs.opencryptoki ]; Rebuild the NixOS configuration with the following command: $ sudo nixos-rebuild switch |
