3.1.3.1 adm

Information

This change locks and disables login access for the adm user account.

Rationale:

This change disables direct local and remote login to the adm user account. Do not set a password on this account to ensure that the only access is via su from the root account.

There should not be a requirement to log in as the adm user directly. All users should be given unique logon ids to ensure traceability and accountability.

Solution

Change the following user attributes to adm user:

chuser account_locked=true login=false rlogin=false adm

Default Value:

account_locked=false rlogin=true login=true
