Notice the gray down-arrow next to the <strong>Firewall</strong> Rule checkboxes. These appear if you have<br />

defined multiple interfaces in the previous step. They allow you to specify whether the <strong>Firewall</strong><br />

Rule will apply globally to all interfaces on the Computer or just to interfaces that you specify.<br />

Leave these at the default (global) setting for now.<br />

2. Click the Save button.<br />

We assigned a <strong>Firewall</strong> Rule that permitted Windows File Sharing. Windows File Sharing is a very<br />

useful feature in Windows but it has had some security issues. It would better to restrict this<br />

ability to when the laptop is in a secure office environment and forbid it when the laptop is out of<br />

the office. We will apply Location Awareness to the <strong>Firewall</strong> Rule when used with this Security<br />

Profile to implement this policy.<br />

3. In the new Security Profile's Details screen, right-click the Windows File Sharing <strong>Firewall</strong> Rule<br />

and select Properties (for this Security Profile). This will display the Properties window for<br />

the <strong>Firewall</strong> Rule but the changes we make to it will only apply to the <strong>Firewall</strong> Rule when it is<br />

applied as part this new Security Profile:<br />
