Discussion

Allowing any user to elevate their privileges can allow them excessive control of the system tools.

Check Content

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 Text

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]
