Erect a firewall

Always-on Internet connections will leave you more vulnerable to attacks, unless you install a firewall. Thursday, April 5, 2001 Erect a firewall Always-on Internet connections will leave you more vulnerable to attacks, unless you install a firewall.

If you’re looking for a faster Internet connection, chances are you’re considering one of the high-speed options available with DSL or cable modems. While these high-speed connections will help you surf the Internet and download files much faster, they are “always on” connections. This means your PC will be connected to the Internet for as long as your PC is on. Unfortunately, this also means that your PC will be vulnerable to hackers. If you want protection against uninvited guests inside your PC, install a firewall program such as Norton Firewall, BlackICE Defender, or McAfee Firewall. These programs monitor traffic between your system and the Internet, and will inform you when suspicious activity occurs.
