Some systems are more secure out of the box than others.
Unfortunately, Linux is not one of them. For example, if you don t need your system to be a web server, rename the start-up script that executes at boot time. If you don t want mail to come in or out, don t start up Sendmail. It is also one of the more popular systems for hackers to develop their code on because the software is free and all of the source code is available. As a result, Linux is one of the first operating systems where users discover that there is a new security hole.
