| Description |
|---|
| Cryptographic hashes provide quick password authentication while not actually storing the password. |
| ℹ️ Check |
|---|
| Determine which cryptographic algorithms are configured. # grep ^CRYPT /etc/security/policy.conf If the command output does not include the lines, this is a finding. CRYPT_DEFAULT=6 CRYPT_ALGORITHMS_ALLOW=5,6 |
| ✔️ Fix |
|---|
| The root role is required. Configure the system to disallow the use of UNIX encryption and enable SHA256 as the default encryption hash. # pfedit /etc/security/policy.conf Check that the following lines exist and are not commented out: CRYPT_DEFAULT=6 CRYPT_ALGORITHMS_ALLOW=5,6 |
