It then describes some tools you can try out from a bootable Linux system
to troubleshoot your computer and network.
Linux Security Checklist
While most Linux systems offer all the tools you need to secure your computer, if you are reckless,
someone can (and probably will) harm your system, take it over, or try to steal your data. Keep in
mind that no security measures are 100 percent reliable and that, given physical access to a computer
or an unlimited amount of time to try to break in, a skilled and determined cracker can
break into any computer.
That said, however, there are many safeguards you can take to improve your chances of keeping
your Linux system safe. The following checklist covers a range of security features to protect your
Linux desktop or server.
Control physical access. Keeping your computer behind locked doors is a good idea,
especially if your computer contains critical data. You can limit what a person can do to
your computer with physical access by enabling passwords in the BIOS (to prevent the
computer from booting at all) and in the GRUB or LILO boot loader. You can also limit
which devices can be booted in the BIOS.
Add users and passwords. Creating separate user accounts (each with a good password)
is your first line of defense in keeping your data secure.
