Newer versions of Mac OS X are set with two diverse network firewalls. A firewall can be software mounted on the computer or a hardware modem like a router. Its primary function is to guard your computer’s network from malicious connections while allowing the clean and legitimate ones to work.

OS X Firewall acts like a filtering device that sifts and guards your computer against network threats. Each port is like a room that contains a network application for file sharing, web access and document controls. The illegal task of malicious programmers is to have access to these rooms and take advantage of your files, harass your web contacts and steal your personal documents. You are probably thinking are the firewalls strong enough to protect your Apple Server?

Built-in OS X Firewalls

First, let’s try to get to know the two native Firewalls in the Mac OS X versions. The first one is called packet-filtering firewall, an application that technically classifies network traffic. Packet-filtering firewall can block any IP port or online connection that goes against its standards and rules. It categorizes the good and the bad entries based on port address, source and file destination.

The second built-in system defense is called Socket-filter firewall. The socket-filter firewall screens the connecting ports by checking if it is listed on its own authenticity list, just like a club bouncer with his own VIP guest list.

Protection against Mac Vulnerabilities

The belief that a Mac computer cannot acquire any virus is just a myth. Mac OS, like all the other operating systems, is also vulnerable and prone to malware and other digital threats.

Up till now, there are very little known threats that have managed to infect Mac users, compared to the record of Windows computers. The inclusion of Firewall software definitely enhanced the strength of Mac’s operating system. However, it cannot automatically protect the computer network. Firewall wouldn’t be able to filter unless the user turns it on. And added to that, firewall can only protect your computer against network disputes. OS X Firewall cannot fight an internal system virus that leaks from a new hard drive or USB port that you connected on your computer. In other words, firewall can guard your network from threats that might come from iOs App hosting, internet surfing and scheduled software updates. But you still need a separate anti-virus that can defend your system programs.

Firewall Configuration

To enable the OS X firewall, you should click on the “Security and Preference” tab and look for the Firewall option. Security and Preference is located under the “System Preferences” options. On the firewall option, unlock the application and type your administrator password, and click “Turn on Firewall.” That should launch your built-in Mac OS firewall.

Adding Entries

You can control and customize your own firewall settings. You can allow Mac Hosting related connection to pass through your firewall. You can easily do this by modifying your Firewall options.

In closing the Mac OS X firewall is only effective if you enable it. Once enabled you’ll be protected from various Internet threats. Its highly recommended that you enable the firewall software on all production servers not already protected by a dedicated firewall.

Mac Mini World offers the technical support required to configure a firewall and also offers customers dedicated or shared firewall options depending on their needs.
