<br>
There are many toolkits that
are avaible for individuals to help "harden" their computer systems...<br /><br />
Examples include: <b>Live Hacking CD</b>, <b>Samurai Web Testing Framework</b>,
<b>Organizational Systems Wireless Assistant.</b>, <b>Ardius</b>, <b>Operator</b>", etc. There are even distributions for the <b>Raspberry Pi</b> (although we need to have a pen testing solution support virtual machines for this course).
<br><br>
TE:
Make certain NOT to accept the default computer name. Use a smaller
name (like three letters), otherwise, the telnet server package will NOT
be installed by default
One tookit that contained many of the penetration-testing tools taught in this course was <b>BackTrack</b>. BackTrack is a specialized distribution based on Ubuntu. A newer distribution called <b>Kali Linux</b> is a newer and more complete build of Linux Backtrack using Debian (i.e. Kali is "BackTrack 6"). There is a noticeable improvement which includes fixes to "broken packages" (less hassle to the student to setup and use), as well as better wireless support, and better flexibility for customization.<br /><br /><b>We will be using Kali Linux for this semester...</b><br /><br />

<div><b>Our Labs Assume Using a Removable Hard Disk</b><br>Although there are several ways to setup your pentration testing system, this lab will assume that you are using a removable hard disk.<br /><br />
Whichever configuration you decide to use, your system MUST allow both the Kali Linux system to be running at the same time as your other vulnerable Windows and Linux operating systems (to conduct penetration testing).
<br><br><b>NOTE:
It is recommended NOT to use all disk space for the host machine, since
a future assignment may require the installation of other host and VM
operating system...</b>.
</div>
</div>
<br>
INSTRUCTIONS:
<ol>
<li><b>Use your Hard Disk Pack solely for this course: Do not share the
contents with this diskpack with any other courses that you are taking</b>.
Remember: this is a course dealing with "Internet Security" which means
that you could lose your work if you do something wrong.</li>
<li>Obtain the <b>Kali Linux installation media</b> (eg. DVD, USB Stick).</li>
<li>Insert your Hard Disk Pack and Kali Linux CD into your lab machine.</li>
<li>Boot your lab machine, and at the BIOS display, press <b>F10</b> (password: <b>ENTER</b>) and then select <b>the CD/DVD drive containing the Kali Linux install media</b> for boot selection.
</li><li>Select the first <b>INSTALL</b> option in the Kali Linux startup menu.</li>
<li>Accept the recommended or default selections during the install. Remember to write down any passwords (do not forget them!). You may want to (when prompted) add a non-existent username to the administrator's group that you can add later to have admin access.</li>
<li>When you have completed your install, remove the installation media, restart your Kali Linux machine.</li>
<li>Make certain that you can connect to the Internet (confirm by using a web-broswer)</li>
</ol>

<div><b>Caution When Running XWindows as Root</b><br>It is usually a
"bad idea" to run XWindows as root. Running a graphical environment that
has the privileges as root can cause damamge when users become
accustomed to working in an everyday environment. It is suggested to create a regular user (same one that you added to group admin).<br /><br />
</div>
</div>
<ol>
<li value="9">You can use the <b>Synaptic Package Manager</b> (graphic tool) or the Linux commands <b>apt-get</b> to install other applications that you wish to use in on your system (eg. different web-browser).</li>
<li>It is recommended NOT to graphically install VirtualBox on your Kali machine. The lab's author has had success with installing VirtualBox (as a .deb file) from the main website.</li>
<li>Download the appropriate VirtualBox .deb file (32/64 bit) from the following link:<br /><a href="https://www.virtualbox.org/wiki/Downloads" target="_blank">https://www.virtualbox.org/wiki/Downloads</a> <br /><br /></li>
<li>After the file has downloaded, open a Linux shell, go to the directory containing the downloaded file Issue the following command as root:</li>
</ol>
<pre>
gdebi [filename]
</pre>
<ol>
<li value="13">Make appropriate selections to have VirtualBox application installed.</li>
<li>Start the VirtualBox application. If the appliation does not appear in any of the menus, simply run the <b>virtualbox</b> command in root in a shell terminal.</li>
<li>Proceed to Task #2</li>
</ol>
<p><b>Answer the Task #1 observations / questions in your lab log book.</b>

<div><b>Other Vulnerable Linux Distributions</b><br>Although we will be
using an outdate version of Fedora Linux, there are other Linux
distributions of Linux that are designed with security flaws for
penetration testing. An example would be <b>DVL</b> (<i>Damn Vulnerable Linux</i>). For interest, here is a link to download and install DVL:<br> <a href="http://sourceforge.jp/projects/sfnet_virtualhacking/downloads/os/dvl/DVL_1.5_Infectious_Disease.iso/">http://sourceforge.jp/projects/sfnet_virtualhacking/downloads/os/dvl/DVL_1.5_Infectious_Disease.iso/</a>.

<div><b>Testing Vulnerable Operating Systems</b><br>Since this course
will be exploring security issues with operating systems, weak or
"outdated" operating systems are preferred. This seems to run against
our nature to update an operating system immediately after an
installation. <b>You are allowed to update your host OS, but do NOT run updates on the vulnerable OS (Virtual Machines)</b>. You will update (or "harden") those vulnerable operating systems in later labs...

There are many toolkits that
are avaible for individuals to help "harden" their computer systems...<br /><br />
Examples include: <b>Live Hacking CD</b>, <b>Samurai Web Testing Framework</b>,
<b>Organizational Systems Wireless Assistant.</b>, <b>Ardius</b>, <b>Operator</b>", etc. There are even distributions for the <b>Raspberry Pi</b> (although we need to have a pen testing solution support virtual machines for this course).
<br><br>
TE:
Make certain NOT to accept the default computer name. Use a smaller
name (like three letters), otherwise, the telnet server package will NOT
be installed by default
One tookit that contained many of the penetration-testing tools taught in this course was <b>BackTrack</b>. BackTrack is a specialized distribution based on Ubuntu. A newer distribution called <b>Kali Linux</b> is a newer and more complete build of Linux Backtrack using Debian (i.e. Kali is "BackTrack 6"). There is a noticeable improvement which includes fixes to "broken packages" (less hassle to the student to setup and use), as well as better wireless support, and better flexibility for customization.<br /><br /><b>We will be using Kali Linux for this semester...</b><br /><br />

<div><b>Our Labs Assume Using a Removable Hard Disk</b><br>Although there are several ways to setup your pentration testing system, this lab will assume that you are using a removable hard disk.<br /><br />
Whichever configuration you decide to use, your system MUST allow both the Kali Linux system to be running at the same time as your other vulnerable Windows and Linux operating systems (to conduct penetration testing).
<br><br><b>NOTE:
It is recommended NOT to use all disk space for the host machine, since
a future assignment may require the installation of other host and VM
operating system...</b>.
</div>
</div>
<br>
INSTRUCTIONS:
<ol>
<li><b>Use your Hard Disk Pack solely for this course: Do not share the
contents with this diskpack with any other courses that you are taking</b>.
Remember: this is a course dealing with "Internet Security" which means
that you could lose your work if you do something wrong.</li>
<li>Obtain the <b>Kali Linux installation media</b> (eg. DVD, USB Stick).</li>
<li>Insert your Hard Disk Pack and Kali Linux CD into your lab machine.</li>
<li>Boot your lab machine, and at the BIOS display, press <b>F10</b> (password: <b>ENTER</b>) and then select <b>the CD/DVD drive containing the Kali Linux install media</b> for boot selection.
</li><li>Select the first <b>INSTALL</b> option in the Kali Linux startup menu.</li>
<li>Accept the recommended or default selections during the install. Remember to write down any passwords (do not forget them!). You may want to (when prompted) add a non-existent username to the administrator's group that you can add later to have admin access.</li>
<li>When you have completed your install, remove the installation media, restart your Kali Linux machine.</li>
<li>Make certain that you can connect to the Internet (confirm by using a web-broswer)</li>
</ol>

<div><b>Caution When Running XWindows as Root</b><br>It is usually a
"bad idea" to run XWindows as root. Running a graphical environment that
has the privileges as root can cause damamge when users become
accustomed to working in an everyday environment. It is suggested to create a regular user (same one that you added to group admin).<br /><br />
</div>
</div>
<ol>
<li value="9">You can use the <b>Synaptic Package Manager</b> (graphic tool) or the Linux commands <b>apt-get</b> to install other applications that you wish to use in on your system (eg. different web-browser).</li>
<li>It is recommended NOT to graphically install VirtualBox on your Kali machine. The lab's author has had success with installing VirtualBox (as a .deb file) from the main website.</li>
<li>Download the appropriate VirtualBox .deb file (32/64 bit) from the following link:<br /><a href="https://www.virtualbox.org/wiki/Downloads" target="_blank">https://www.virtualbox.org/wiki/Downloads</a> <br /><br /></li>
<li>After the file has downloaded, open a Linux shell, go to the directory containing the downloaded file Issue the following command as root:</li>
</ol>
<pre>
gdebi [filename]
</pre>
<ol>
<li value="13">Make appropriate selections to have VirtualBox application installed.</li>
<li>Start the VirtualBox application. If the appliation does not appear in any of the menus, simply run the <b>virtualbox</b> command in root in a shell terminal.</li>

<div><b>Testing Vulnerable Operating Systems</b><br>Since this course
will be exploring security issues with operating systems, weak or
"outdated" operating systems are preferred. This seems to run against
our nature to update an operating system immediately after an
installation. <b>You are allowed to update your host OS, but do NOT run updates on the vulnerable OS (Virtual Machines)</b>. You will update (or "harden") those vulnerable operating systems in later labs...
