| Description |
|---|
| Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. |
| ℹ️ Check |
|---|
| Verify NixOS enforces password complexity by requiring at least one numeric character with the following command: $ grep dcredit /etc/security/pwquality.conf dcredit=-1 If the value of "dcredit" is a positive number or is commented out, this is a finding. |
| ✔️ Fix |
|---|
| Configure NixOS to enforce password complexity. Add/modify /etc/nixos/configuration.nix to include the following lines: environment.etc."/security/pwquality.conf".text = '' dcredit=-1 ''; Rebuild the system with the following command: $ sudo nixos-rebuild switch |
