Security Considerations

Your computer running Mac OS X is a powerful operating system, and with that power comes a new set of security risks. If you're connecting your computer to the Internet, it's necessary that you pay attention to your system as well as take preventive measures to guard against unwanted connections. (While this may sound paranoid , my personal computer, which is connected to the world via cable modem, is attacked dozens of times a day by people who simply search for unprotected computers online.)
