Upgrading to a Cable Modem--Part 5 of 5
PC security becomes an issue when you upgrade to a cable modem service for Internet access. The "always-on" feature of cable modem services really means you are connected to a computer network, which your cable service administers via a static IP address. A static IP address makes it easy for intruders to browse your hard drive without your knowing about it.

One easy security measure is to restrict the file-and print-sharing setttings in your operating system. Another security measure is to purchase one of the new software products in the personal firewall category; these can detect intruders and protect your system from attack.
