Firewalls monitor and regulate the data moving on and off your computer or network. They can keep criminals out while allowing legitimate network traffic in. Mac OS X comes with not one but two firewalls of its own. However, those two aren’t always enough. The Threat Years ago, a bug (long-since fixed) let attackers send Macs a so-called “”—specially designed network traffic that could crash a system.
There aren’t any such network vulnerabilities on Macs (that we know of) now, but many of Apple’s security updates specifically address network vulnerabilities. Clearly, Macs aren’t inherently immune. With millions of computers in the world, it might seem that the odds of your Mac being targeted are awfully small. But there are computers out there that do nothing all day but probe Net-connected machines for vulnerabilities; it’s certainly possible that one will find yours. And don’t forget that any time you’re on a network—a coffee shop’s Wi-Fi system, for example—you’re exposed to anyone else on that network. The risks—the loss of private data and the hijacking of your Mac’s computing power—are great enough, and the cost of prevention low enough, that implementing a good firewall on your Mac and your local network is a no-brainer.

OS X’s Firewalls All versions of OS X through 10.4 (Tiger) have included a Unix-based firewall called. In security parlance, ipfw is a packet-filtering firewall: it checks each packet coming or going through the Mac’s network interfaces against a set of rules, and allows it to pass or blocks it. Packet-filtering firewalls like ipfw classify network traffic two ways: by type, using port numbers, and by origin and destination, using IP addresses. For instance, a packet-filtering firewall could accept file-sharing connections from IP addresses of your work network but not from other addresses on the Internet. To ipfw, Leopard adds a new (also known as an application firewall). Rather than using network ports and IP addresses to decide whether to allow a packet, it bases its decision on the application making the network request. When a program asks to accept network traffic, a socket filter checks a list of programs that have been authorized to do so.

If the program is on the list, the firewall allows the connection. If the program isn’t on the list—as in the case of new or upgraded software—OS X asks you whether to allow the program to accept incoming traffic. The Security preference pane lets you configure OS X’s built-in socket-filter firewall, which filters network traffic by application.You enable Leopard’s socket firewall by selecting Set Access For Specific Services And Applications in the Firewall tab of the Security preference pane.
When you select that option, you’ll see a list of allowed and blocked programs. If you’d like to block all nonessential traffic, you can select Allow Only Essential Services, but beware: doing so will break some applications. You’ll still be able to browse the Web and use e-mail, but other inbound connections will be blocked.

Socket filters are less flexible than a packet filter like ipfw. Applications that are allowed to accept network connections will accept them from anywhere on the Internet; they can’t be told to distinguish trusted from untrusted Net addresses. The Leopard firewall also blocks only inbound connections; it won’t prevent programs from making outbound connections. This has become a big problem in the Windows world: spyware programs lodge themselves on hard drives and then “phone home” with sensitive private information. While OS X 10.5 still includes ipfw, it’s effectively disabled by default.
