<br />
<b>NTFS</b> is a newer file system developped for Windows operating systems that provide improved disk space utilization, file system journaling, as well as security. This newer file system technology incorporates <b>Access Control Lists (ACLs)</b> which you have learned and configured in <i>lab #5: Linux Hardening - Part 2</i>.
<br /><br />
In this section, we will learn how to use ACLs to "finely-tune" group access to directories and files, and differentiate between setting permissions via ACL and setting permissions .
<br /><br />
INSTRUCTIONS:
<ol>
<li>Read the tutorial on how to use ACLs with Windows NTFS Permissions at the following link:<br /><a href="http://www.windowsecurity.com/articles/understanding-windows-ntfs-permissions.html" target="_new">Understanding Windows NTFS Permissions</a></li>
<li>Perform the following steps (as in Lab #5, but using Windows NTFS Permissions):<ol>
<li>Create the following directory: <b>c:\share</b></li>
<li>Set passthrough permissions, and set permissions for the share
directory to allow students to access and list contents for this
directory.</li>
<li>Use the groupadd command to create a new group name called <b>project</b> </li>
<li>Create a file in the share directory called <b>project.txt</b> </li>
<li>Set permissions for same group members to view and modify contents of the file <b>C:\share\project.txt</b></li>
<li>Create two user accounts called: <b>user1</b> and <b>user2</b> (Use the <b>useradd</b> command with an option to create a home directory and to belong to group: <b>project</b>.</li>
<li>Switch to <b>user1</b>, and confirm that they can access and modify the file: <b>C:\share\project.txt</b></li>
<li>Repeat the above step for <b>user2</b>.</li>
<li>Why can't you allow <b>user1</b> to read and modify the project.txt file, but only allow <b>user2</b> to only read the project.txt file? Answer in your lab log-book.</li>
</ol></li>
<li>Proceed to Task #3.</li>

<br />
In this section, we will be using similar techniques to monitor suspicious activity in your Windows 2003 server as you did in <b>lab7</b> (for your Linux server). The tools in Windows will be a combination of Graphical and command-line.
<br /><br />
INSTRUCTIONS:
<ol>
<li>In your hardened Windows server, open the command prompt.</li>
<li>Run the <b>Event Manger</b> graphical tool by issing the following MS command:
<pre>
<b>eventvwr.msc</b>
</pre>
<br />
Check the logs for the following activity:
<ul>
<li>Event logging stopped</li>
<li>Windows File Permission not active</li>
<li>Telnet Service started successfully (this service is vulnerable)</li>
<li>Significant number of unsuccessful login attempts</li>
</ul>
<br />
</li>
<li>Run the following graphical and command-line tools, in order to view and identify all of the services running on your Windows 2003 server (both normal and suspicious):
<pre>
<b>taskmgr.exe</b>
<b>services.msc</b>
<b>tasklist /svc</b>
</pre>
<br />
As with the previous Linux hardenening lab, determine which services are vulnerable, and shut-down vulnerable or unnecessary services. Which services did you shut down? Record your answer in your lab log-book.
<br /><br />
<li>Perform a <b>Search for Files or Folders</b> that are over 10000KB in size (i.e. use the <b>search options</b> before starting search). Did you locate any files of this size? What do you think files greater than 10000KB would indicate? Record your answers in your log lab-book.
<li>View your Windows registry file to detect any suspicious or strange programs by issuing the following command:
<pre>
<b>regedit</b>
</pre>
<br />
For interest, perform a <i>netsearch</i> for a listing of common programs (contained in the registry) that could pose a hazard to your Windows system.
<br /><br />
<li>Next, issue the following MS commands in order to detect unusual network activity:
<pre>
<b>net view</b>
<b>net session</b>
<b>net user</b>
<b>netstat -na</b>
</pre>
<br /></li>
<li>Run the following Windows commands to observe any unusual scheduled tasks:
<pre>
<b>schtasks</b>
<b>msconfig.exe</b>
</pre>
<br /></li>
<li>Finally, run the following Windows command to detect any unusual (recentrly added) user accounts to the Windows system:
<pre>
<b>lusrmgr.msc</b> </pre>
<br /></li>
</ol>

<br />
<b>NTFS</b> is a newer file system developped for Windows operating systems that provide improved disk space utilization, file system journaling, as well as security. This newer file system technology incorporates <b>Access Control Lists (ACLs)</b> which you have learned and configured in <i>lab #5: Linux Hardening - Part 2</i>.
<br /><br />
In this section, we will learn how to use ACLs to "finely-tune" group access to directories and files, and differentiate between setting permissions via ACL and setting permissions .
<br /><br />
INSTRUCTIONS:
<ol>
<li>Read the tutorial on how to use ACLs with Windows NTFS Permissions at the following link:<br /><a href="http://www.windowsecurity.com/articles/understanding-windows-ntfs-permissions.html" target="_new">Understanding Windows NTFS Permissions</a></li>
<li>Perform the following steps (as in Lab #5, but using Windows NTFS Permissions):<ol>
<li>Create the following directory: <b>c:\share</b></li>
<li>Set passthrough permissions, and set permissions for the share
directory to allow students to access and list contents for this
directory.</li>
<li>Use the groupadd command to create a new group name called <b>project</b> </li>
<li>Create a file in the share directory called <b>project.txt</b> </li>
<li>Set permissions for same group members to view and modify contents of the file <b>C:\share\project.txt</b></li>
<li>Create two user accounts called: <b>user1</b> and <b>user2</b> (Use the <b>useradd</b> command with an option to create a home directory and to belong to group: <b>project</b>.</li>
<li>Switch to <b>user1</b>, and confirm that they can access and modify the file: <b>C:\share\project.txt</b></li>
<li>Repeat the above step for <b>user2</b>.</li>
<li>Why can't you allow <b>user1</b> to read and modify the project.txt file, but only allow <b>user2</b> to only read the project.txt file? Answer in your lab log-book.</li>

<br />
In this section, we will be using similar techniques to monitor suspicious activity in your Windows 2003 server as you did in <b>lab7</b> (for your Linux server). The tools in Windows will be a combination of Graphical and command-line.
<br /><br />
INSTRUCTIONS:
<ol>
<li>In your hardened Windows server, open the command prompt.</li>
<li>Run the <b>Event Manger</b> graphical tool by issing the following MS command:
<pre>
<b>eventvwr.msc</b>
</pre>
<br />
Check the logs for the following activity:
<ul>
<li>Event logging stopped</li>
<li>Windows File Permission not active</li>
<li>Telnet Service started successfully (this service is vulnerable)</li>
<li>Significant number of unsuccessful login attempts</li>
</ul>
<br />
</li>
<li>Run the following graphical and command-line tools, in order to view and identify all of the services running on your Windows 2003 server (both normal and suspicious):
<pre>
<b>taskmgr.exe</b>
<b>services.msc</b>
<b>tasklist /svc</b>
</pre>
<br />
As with the previous Linux hardenening lab, determine which services are vulnerable, and shut-down vulnerable or unnecessary services. Which services did you shut down? Record your answer in your lab log-book.
<br /><br />
<li>Perform a <b>Search for Files or Folders</b> that are over 10000KB in size (i.e. use the <b>search options</b> before starting search). Did you locate any files of this size? What do you think files greater than 10000KB would indicate? Record your answers in your log lab-book.
<li>View your Windows registry file to detect any suspicious or strange programs by issuing the following command:
<pre>
<b>regedit</b>
</pre>
<br />
For interest, perform a <i>netsearch</i> for a listing of common programs (contained in the registry) that could pose a hazard to your Windows system.
<br /><br />
<li>Next, issue the following MS commands in order to detect unusual network activity:
<pre>
<b>net view</b>
<b>net session</b>
<b>net user</b>
<b>netstat -na</b>
</pre>
<br /></li>
<li>Run the following Windows commands to observe any unusual scheduled tasks:
<pre>
<b>schtasks</b>
<b>msconfig.exe</b>
</pre>
<br /></li>
<li>Finally, run the following Windows command to detect any unusual (recentrly added) user accounts to the Windows system:
<pre>
<b>lusrmgr.msc</b> </pre>
<br /></li>
</ol>

As a matter of interest, there is an alternative IDS for MS Windows (amoung other platforms). The name of the application is called <b>OSSEC</b> which is a scalable, multi-platform, and open source (free).<br /><br />Here is a link to this application:<br />
