Project: Be Secure ` As a computer user, you should be aware of how to protect yourself by configuring security settings for your web browser. In the lab or with your own computer running Windows 7 and Internet Explorer, let us spend some time reviewing the Windows Firewall settings and Internet security settings including the Parental Controls section. Write down existing settings so you can restore the system to its original configuration when you finish the lesson.

Change the security level to the default High, and visit the same set of sites. Then change the security level to default Low and visit the sites again. Make notes about how these settings impact the sites you can visit and how you experience the web. Restore these settings back to the original before you complete the lesson.

How does a particular security setting affect each case? What happens when you try to link to a site you cannot access? What kind of message do you get, and why? What do you think is the optimum setting for parental controls and Inter
