The information contained in this chapter applies in general to all Samba installations. Security is
everyone's concern in the information technology world. A surprising number of Samba servers are being
installed on machines that have direct internet access, thus security is made more critical than it would have been had the
server been located behind a firewall and on a private network. Paranoia regarding server security is causing
some network administrators to insist on the installation of robust firewalls even on servers that are located
inside secured networks. This chapter provides information to assist the administrator who understands
how to create the needed barriers and deterents against “the enemy”, no matter where [s]he may
come from.
A new apprentice reported for duty to the chief engineer of a boiler house. He said, “Here I am,
if you will show me the boiler I'll start working on it.” Then engineer replied, “You're leaning
on it!”
Security concerns are just like that. You need to know a little about the subject to appreciate
how obvious most of it really is. The challenge for most of us is to discover that first morsel
of knowledge with which we may unlock the secrets of the masters.
