Fix Recommendation

From the bash shell, configure the sudo group with only members requiring access to security functions.

To remove a user from the sudo group, run:

$ sudo gpasswd -d <username> sudo

Check Contents

From the NetIM shell, verify the sudo group has only members who require access to security functions by using the following command:

[netimsh] :~$ shell cat /etc/group |more

For the entries with sudo:x:27:<username>, verify the only username on the list is NetIMAdmin.


If the sudo group contains users not needing access to security functions, this is a finding.
