Basic Security for RedHat

[Kalpin Erlangga Silaen <kalpin () solonet co id>]

Dear all,

I am using RedHat 9.0 and there is 3 admin in my server. I am looking 
for some tools which will send email to me while some admin adduser or 
change user's password. Also I am looking for some tutorials how to 
limits user's resources in RedHat and some security basics.

Any help will be appreciate.
