Check Text (C-215338r991589_chk)
Examine the "sugroups" of the root user. Generally only users in the adm group should have su to root capacity.
Run the following command:
# lsuser -a sugroups root
root sugroups=system,staff,security
If "sugroups" is blank or "ALL", this is a finding.
Fix Text (F-16534r294466_fix)
Use the "chsec" command to only allow users in the adm group to su to root:
# chsec -f /etc/security/user -s root -a sugroups=adm
