Easy.
A secure server is one that communicates with clients using a secure
protocol, usually SSL (AKA Secure Sockets Layer). Examples of secure
server software are Stronghold, Apache with SSL, etc.
"Secure" in this case refers to the communications, rather than the
server itself. To make the server itself reasonably secure requires
(a) a relatively robust operating system, (b) tools such as
firewalls, and (c) a system/network manager who knows what she's
doing and does it.
