security
Because Linux is basically
a Unix variant it can be an extremely secure operating system.
However it can also be difficult to configure and quite complex
depending on the distribution in use. Also, because security
issues change constantly and new threats appear all the time
keeping current can be a problem. Currently most of the major
Linux
distributions do provide a means to keep up-to-date with
the latest versions of the different programs and files that
make up a Linux system. Updating and patching system files is
especially important for any Linux system. Also upgrading to
the latest stable version of the Linux kernel can provide added security.
And if possible always use the latest version of your distribution
as numbered by the software producers.

security and various distributions as well as the

pages and the Linux FAQ.
General guidelines:
- Use a firewall, either hardware,
software or both for any network connection
- Use anti-virus software and
keep it up-to-date
- Keep operating system files and application files patched
and up-to-date
Additionally there are some measures one can use to further
secure their Linux system.
- Enable shadow password support. You should enable
the shadow password feature. You can use the "/usr/sbin/authconfig"
utility to enable the shadow password feature on your system.
If you want to convert the existing passwords and groups on your
system to shadow passwords and groups then you can use the commands
pwconv, and grpconv respectively.
- BIOS Security. Always set a password for your BIOS
to disallow booting from floppy or cd-rom by changing the BIOS
settings. This will block undesireable people from trying to
boot your Linux system with a special boot disk and will protect
you from people trying to change BIOS feature like allowing boot
from floppy drive or booting the server without password prompt.
