FIND OUT ABOUT FIREWALLS:-
Go to the Web and find out about software and hardware that protect your computer and home network, respectively. If you have only one computer connected to the Internet, then a software firewall like Zone Alarm will most likely be enough protection from intruders.
Find three different firewall software packages on the Web. A good place to start looking would be the sites that sell anti-virus software. Compare the fi rewall software on price and features.
Some sites to try are Symantec at www.symantec.com Trend Micro at www.trendmicro.com McAfee at www.mcafee.com The Virus List (a virus encyclopedia) at www.viruslist.com If you have a home network, look into hardware firewall options. How many different hardware firewalls can you find on the Web site of your favorite electronics retailer?
(Hint: Look in the feature lists of home routers and broadband routers, even if they don't have the word firewall in their name.)
