Therefore it is better to be prepared and hence, Mac users are advised to install Macintosh firewall software for their Mac's protection.

A Macintosh Firewall software can deal with various problems. It can block certain selected network connections to your computer. Basically it protects the Macintosh against all types of attacks that come from the Internet. It is pre-configured for blocking any incoming connections that originate from other computers to all the open network ports on a Mac.

The Macintosh Firewall software can also be configured to block certain outgoing connections. These outgoing connections may be controlled by viruses, worms, or Trojans. Blocking these connection definitely helps to avoid certain big problems.

Certain Macintosh Firewall software packages can offer additional configuration options and features. Some of these features are allowing selected computers to establish connections to a Mac. The software packages are also able to log successful or failed connection attempts.

The Macintosh Firewall software installs a personal firewall software, which is also called a host based firewall. The firewall usually runs directly on a single Macintosh and usually protects only that Mac. This personal firewall is different from the network firewalls that protect multiple computers. However, these two firewalls complement each other. Together they can prevent certain types of attacks that the others cannot.

Apple Inc. provides a Macintosh firewall software with the Mac OS X. It is one of the most popular firewall software for Macintosh. The name of the Macintosh firewall software is ipfw. It is in Mac OS X 10.5 Leopard too, but the OS also has another default firewall.
