| Description |
|---|
| Allowing any user to elevate their privileges can allow them excessive control of the system tools. |
| ℹ️ Check |
|---|
| Verify the root user is configured as a role, rather than a normal user. # userattr type root If the command does not return the word "role", this is a finding. Verify at least one local user has been assigned the root role. # grep '[:;]roles=root[^;]*' /etc/user_attr If no lines are returned, or no users are permitted to assume the root role, this is a finding. |
| ✔️ Fix |
|---|
| The root role is required. Convert the root user into a role. # usermod -K type=role root Add the root role to authorized users' logins. # usermod -R +root [username] Remove the root role from users who should not be authorized to assume it. # usermod -R -root [username] |
