Setup for Labs

Introduction

This lab teaches the student how and why attackers break into systems. For this purpose everyone will be a "victim" in the class as well as a "bad guy". Generally, we try to envision a network server environment.

Unfortunately, performing penetration system testing on an organization's network without their consent can lead to serious consequences. The college has created a lab that allows students to perform penetration testing in a safe environment - it is called the IFS Lab. This lab is in heavy demand due to the IFS program, and may not be available for SEC520 students. Another method to encourage the "safe and permitted practice of penetration testing at the college" is to have students host vulnerable operating systems as virtual machines on their host computer system (i.e. Hard Disk Packs).

This lab assumes that you already have the required materials (listed below in the Required Materials section), and are ready to perform this lab.

Objectives

Install Kali Linux (host) on hard disk pack (or other suitable configuration).
Install Virtual Machine application called VirtualBox on host OS (Kali Linux).
Setup and install a vulnerable Linux OS as a Virtual Machine on the host.
Setup and install Windows 2003 Server as a Virtual Machine on the host.

Required Materials

SATA Hard Disk in removable disk tray (Note: can use existing Notebook / Netbook with VMware)
Kali Linux Installation DVD (Refer to methods to obtain and burn media in main page).
Vulnerable Linux Installation DVD (Refer to methods to obtain and burn media in main page).
Windows 2003 Server Installation CD (Refer to methods to obtain and burn media in main page).
Lab Logbook (Lab1 Reference Sheet) (to make notes and observations).

Prerequisites

None (First Lab)

Performing Lab 1

Task #1: Install Kali Linux as Host Server on Your Hard Disk Pack (notebook or netbook) and Install VirtualBox

There are many toolkits that

are avaible for individuals to help "harden" their computer systems...

Examples include: Live Hacking CD, Samurai Web Testing Framework, Organizational Systems Wireless Assistant., Ardius, Operator", etc. There are even distributions for the Raspberry Pi (although we need to have a pen testing solution support virtual machines for this course).

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 BackTrack. BackTrack is a specialized distribution based on Ubuntu. A newer distribution called Kali Linux 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.

We will be using Kali Linux for this semester...

Our Labs Assume Using a Removable Hard Disk
Although there are several ways to setup your pentration testing system, this lab will assume that you are using a removable hard disk.

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).

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....

INSTRUCTIONS:

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. Remember: this is a course dealing with "Internet Security" which means that you could lose your work if you do something wrong.
Obtain the Kali Linux installation media (eg. DVD, USB Stick).
Insert your Hard Disk Pack and Kali Linux CD into your lab machine.
Boot your lab machine, and at the BIOS display, press F10 (password: ENTER) and then select the CD/DVD drive containing the Kali Linux install media for boot selection.
Select the first INSTALL option in the Kali Linux startup menu.
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.
When you have completed your install, remove the installation media, restart your Kali Linux machine.
Make certain that you can connect to the Internet (confirm by using a web-broswer)

Caution When Running XWindows as Root
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).

You can use the Synaptic Package Manager (graphic tool) or the Linux commands apt-get to install other applications that you wish to use in on your system (eg. different web-browser).
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.
Download the appropriate VirtualBox .deb file (32/64 bit) from the following link:
<a href="https://www.virtualbox.org/wiki/Downloads" target="_blank">https://www.virtualbox.org/wiki/Downloads</a>
After the file has downloaded, open a Linux shell, go to the directory containing the downloaded file Issue the following command as root:

gdebi [filename]

Make appropriate selections to have VirtualBox application installed.
Start the VirtualBox application. If the appliation does not appear in any of the menus, simply run the virtualbox command in root in a shell terminal.
Proceed to Task #2

Answer the Task #1 observations / questions in your lab log book.

Task #2: Install / Setup Vulnerable Linux OS as a Virtual Machine

Other Vulnerable Linux Distributions
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 DVL (Damn Vulnerable Linux). For interest, here is a link to download and install DVL:
<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>.

Testing Vulnerable Operating Systems
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. You are allowed to update your host OS, but do NOT run updates on the vulnerable OS (Virtual Machines). You will update (or "harden") those vulnerable operating systems in later labs...

INSTRUCTIONS:

In your regular account, run a graphical X-Windows session.
Obtain and burn in the image of Fedora Core 5 onto a bootable DVD.

Here is a link to a downloadable source: <a href="http://dl.fedoraproject.org/pub/archive/fedora/linux/core/5/i386/iso/FC-5-i386-DVD.iso">http://dl.fedoraproject.org/pub/archive/fedora/linux/core/5/i386/iso/FC-5-i386-DVD.iso</a>
( Refer to <a href="http://zenit.senecac.on.ca/wiki/index.php/SEC520#Supplies_Checklist_.28Required_for_Second_Class.29" target="_new">Required Materials</a>)
Insert the Vulnerable Linux (FC5) installation DVD into the DVD Drive.
From the Applications menu, select System Tools, then select Oracle VM VirtualBox.
Click on the New buttoni, and click on Next to proceed.
Enter a name for the Vulnerable Linux system (we will refer to the name of Vulnerable Linux System for the duration of these labs. Make certain that the OS Type is Linux, and the Version is Linux 2.6, and then click on Next to proceed.
Accept the default Base memory size, and click Next to proceed.
Accept all defaults for the Virtual Hard Disk screen, and click Next two times to proceed.
Accept the default Storage Type (i.e. "Dynamically expanding storage"), and proceed to the next screen.
In the Virtual Disk Location and Size, accept the default name, and set the Size of the Partition to 10 GB and proceed to the final screen.
In the Summary screen, verify the information, and click Finish to finish the VM setup.
Double-click on the VM called Vulnerable Linux in order to install that version of Linux from the CD drive.

Auto Capture Keyboard Shortcut Keys
There are a number of

methods to focus the keyboard and mouse on the Virtual Machine (VM) as

opposed to the host machine. The user can accept the default key <right ctrl> to act as a capture toggle-switch.

Accept the defaults in the Anaconda installation wizard, but overide for Eastern Timezone. Select and remember a suitable root password. In the software packages section to include, select Web Server. In addition, select the Customize (i.e. Customize Now, and make the following package selections:
- FTP Server
- Mail Server
- Network Servers
- Server Configuration Tools

Cannot Connect to Internet When Booting from Other Machines
Since you are using an older version of Linux (Fedora Core 5) there is an annoying "connectivity issue" if you have booted from different machines (MAC ADDRESSES). Here is a suggested solution:

In a shell issue the command ifconfig and check if ethX like devices are listed.
login as root by issuing the command: su -- (and enter root password).
Issue the command dhclient
Verify recognized ethernet device by using ifconfig command.

Installing telnet-server
It may be difficult to simply

install applications from repositories for unsupported Linux

distributions (like Fedora Core 5). Instead, perform the following steps:

Download the rpm packages for telnet-server and xinted by clicking on the following links:
<a href="http://rpm.pbone.net/index.php3/stat/4/idpl/16682910/dir/fedora_5/com/telnet-server-0.17-35.2.1.i386.rpm.html">Telnet Server Download Page</a> (select a download mirror)
<a href="http://rpm.pbone.net/index.php3/stat/4/idpl/16683039/dir/fedora_5/com/xinetd-2.3.13-6.2.1.i386.rpm.html">xinetd Dependency Download Page</a> (select a download mirror).
Change directory to where files were downloaded.
Install the xinetd dependency first, then the telnet-server program by using rpm -i <packagename> (you can ignore warnings. If you can't install due to public key issues, you can download public keys from the following site: <a href="http://dl.fedoraproject.org/pub/archive/fedora/linux/core/5/" target="_blank">http://dl.fedoraproject.org/pub/archive/fedora/linux/core/5/</a>.
Issue the command: /sbin/chkconfig telnet on to start the telnet server.

After installing telnet-server, edit the file /etc/xinetd.d/telnet and change to "no" for disable. Then you need to reload xinetd by issuing the command: /sbin/service xinetd reload

You should become familiar with the /sbin/service , /sbin/chkconfig , and /usr/sbin/sestatus to set services, and to provide information to instructor for lab sign-off.

Complete remaining screens to start installation - the installation process should take approximately 30 minutes to complete.
After reboot, the Setup Agent wizard will allow the user to make selections.
Make certain to DISABLE the Firewall and DISABLE SELinux
Create an unprivileged user (remember the password).
Accept all other defaults and allow the system to reboot for changed to take effect.
After reboot, verify that you can login, make the menu selections System, Administration, Server Settings, Services (or issue the command system-config-services to graphically activate and verify all each of the following services are running:
- Web (HTTPD) Server
- FTP (VSFTP) Server
- Mail Server
- SSH Server
- TELNET Server (located under "On Demand" services)
(You can alternatively list service status by issuing the command: /sbin/service --status-all)
<br <="" li="">
Proceed to Task #3

Answer Task #2 observations / questions in your lab log book.

Task #3: Install / Setup Windows 2003 Server as a Virtual Machine

DO NOT Install Service Packs (Beyond Service Pack 1) On Windows 2003 Server
Since

this course will be exploring security issues with the Windows

operating systems, do not update your Window 2003 Server's OS. We will be exploiting this less-secure OS, then later "harden" this OS from attacks.

Do Not Accept Default Computer Name (Use smaller name)

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 (needs to be less than 15 characters).

INSTRUCTIONS:

Obtain an installation CD of Windows 2003 Server (refer to <a href="http://zenit.senecac.on.ca/wiki/index.php/SEC520#Supplies_Checklist_.28Required_for_Second_Class.29" target="_new">Required Materials</a>).
Create another Virtual Machine (20 GB) to be called Vulnerable Windows.
Install Windows Server 2003 (Enterprise Edition) on an NTFS partition. Follow similar selections for settings (such as Eastern Time Zone, administrative password) like you did in Task #2.

!!! NOTE: 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
Choose Application Server as one of the packages.
Complete the other defaults, and allow the system to reboot.
Upon boot-up, similate pressing the <ctrl><alt><del> keys by selecting in the Virtual Box Window menu: Machine, then selecting Insert Ctrl-Alt-Del in order to allow the login screen to appear.
At the Windows Server Post-Setup Updates screen, do NOT perform any updates, and proceed with exiting the screen.
You will proceed to a Windows Server Post-Setup Wizard to help manage your server (like installing services or roles). Make certain that the following wizard settings (or roles) have been added to your Windows server Virtual Machine (for later exploitation):
- NO Updates / NO Automatic Updates
- In the Manage Your Server section, make the following selections (add roles):
  - IIS
    - NOTE: Select Administration, Add Software, view existing services, select IIS, click Details, and then select FTP server.
  - SMTP SERVER
  - TELNET SERVER
    - NOTE: Select Administration, Services, scroll down the list to Telnet, right-click a select View Properties, enable telent server, Apply settings, and then Start the telent server.
  - SSH SERVER
    - NOTE:You can download and install FreeSSH from the following URL:
      <a href="http://www.freesshd.com/freeSSHd.exe" >http://www.freesshd.com/freeSSHd.exe</a>.
