EnGarde Secure Linux: Why not give it a try?
EnGarde Secure Linux is a Linux server distribution that is geared
toward providing a open source platform that is highly secure by default

Linux Command Reference Manual: Linux File Formats
By: Suhas Desai
Linux File Formats
/etc/crontab
The syntax of each line in this file is: minute, hour, day of
month, Month, day of week, (user name), command
/etc/fstab
Columns are: device file to mount, directory to mount on,
filesystem type, options, backup frequency, and fsck pass number
(To specify the order in which filesystems should be checked on
boot; 0 means no check.) The noauto option stops this mount from
being done automatically on boot.
/etc/hosts
Sets up host address information for local use. The format is:
IPaddress name1 name2.
/etc/inittab
Sets the init configuration. An entry in the inittab file has
the following format: id: runlevels: action: process
/etc/passwd
The file has one line per username, and is divided into seven
colonde limited fields:
1. Username.
2. Password, in an encrypted form.
3. Numeric user id.
4. Numeric group id.
5. Full name or other description of account.
This is called gecos.
6. The user's home directory.
7. The user's login shell (program to run at login).
/usr/X11R6/lib/X11/XF86Config
The main XFree86 configuration file.

Linux File & Directory Permissions Mistakes
One common mistake Linux administrators make is having file and
directory permissions that are far too liberal and allow access
beyond that which is needed for proper system operations. A full
explanation of unix file permissions is beyond the scope of this
article, so I'll assume you are familiar with the usage of such
tools as chmod, chown, and chgrp. If you'd like a refresher, one
is available right here on linuxsecurity.com.

Buffer Overflow Basics
A buffer overflow occurs when a program or process tries to
store more data in a temporary data storage area than it was
intended to hold. Since buffers are created to contain a finite
amount of data, the extra information can overflow into adjacent
buffers, corrupting or overwriting the valid data held in them.
