Computers with always-on connections are a favorite target of hackers. Some computers — especially Windows-based computers with shared resources, such as shared folders or printers — announce themselves on the local network so that other users can easily find these shared resources and connect to them. This is great in a home network, but with a cable modem, these computers announce their shared resources to everyone on the same cable segment. This means that your neighbor's printer may show up as a resource as you look for the shared printer on your spouse's computer. Although a cable modem connection does not present a danger to a securely configured computer, many people don't take the proper security precautions and suddenly find that a stranger has connected to their computer or has sent a mystery message to their printer.
