Are Firewalls Necessary?
Recent attacks on major Web sites, such as yahoo.com, and calls for government intervention on cyberterrorism have generated a public perception that all is not well on the World Wide Web.
Now many consumer computer owners are wondering: do I need a firewall?
Broadband Internet users are especially becoming more sensitive to the issue. Because broadband Internet connections, through cable and DSL modems for example, employ permanent IP addresses and maintain a constant open connection, the potential for attacks is higher than the traditional dial-up access.
