In our last article, we focused on email and Spam filtering within Mac OS X.
In the article, we will talk about the Mac OS X personal firewall.
By monitoring network traffic, Mac OS X can act as a firewall to protect your Mac from unauthorized access. When you enable the personal firewall, all inbound connections are denied, except those you explicitly permit.
The Mac OS X firewall is based on technology that protects the most mission-critical UNIX computers on the Internet.
To turn on the personal firewall in Mac OS X, first open the Security pane from System Preferences. Then click the Firewall tab.
Select either “Allow only essential services” or “Set access for specific services and applications” to activate the firewall.
Stealth Mode
Stealth mode protects your Mac from uninvited connections by hiding its existence. When hackers send out “pings” over the Internet to find out which computers are available to attack, your Mac won’t respond.
You turn on stealth mode with the Advanced button in the Firewall window. Select the Enable Stealth Mode option to hide your Mac on the Internet.
Note that in addition to activating stealth mode, you can log the activity of your personal firewall.
Alternatives to the built in firewall
This list is a list of either front ends for the built in firewall, or alternative applications.
If you are looking for more information about the firewall, this article is worth a quick read.
A fantastic article posted by Macworld is also required reading.
If you need for information, please let me know.
