Personal Firewall
The Mac OS X personal firewall protects your computer from unauthorized access by monitoring all incoming network traffic. When you enable the personal firewall in Mac OS X, all inbound connections are denied except for those that you explicitly permit. The personal firewall is based on ipfw, a technology that has stood up to years of real-world use in protecting the most mission-critical UNIX computers on the Internet. The personal firewall is integrated in the Sharing preference pane, with simple on/off checkboxes to enable protection. In addition, it can be customized for additional communication services, IRC, Gnutella, or other user-definable services. |
