One sign of OS X’s overall security savvy is that it has its own built-in firewall, which is pretty good. But there are many other firewall add-on apps for the Mac, including Brian Hill’s. There is a very old belief that Apple and Mac products do not get infected by viruses and, therefore, do not need any malware protection. The reality is that this simply is not the case. A Mac security firm called Intego uncovered a handful of new threats that were targeted specifically at Mac and Apple.

One sign of OS X’s overall security savvy is that it has its own built-in firewall, which is pretty good. But there are many other firewall add-on apps for the Mac, including Brian Hill’s Flying Buttress 1.4, Intego’s NetBarrier X4, Open Door Networks’ DoorStop X Security Suite, SustainableSoftworks’ IPNetSentryX 1.3.1, and Symantec’s Norton Personal Firewall 3.0.3 (see table below below for details).

Guarding the gates

How safe will these apps keep your Mac? In blocking traffic, the differences between these products are razor-thin. They all block bad network traffic and protect your Mac just as they should. But there are two areas where a couple of these apps fall short.

Hackers looking for a computer to exploit may ping yours to see if it’ll reply; if it does, the answer lets them know what operating system your computer is running—an excellent starting point for their nefarious games. In our testing, Apple’s built-in firewall, Flying Buttress, and Norton all spilled the beans about which OS our test system used.

Originally introduced with OS X El Capitan, System Integrity Protection, usually referred to as SIP, is a security feature built into the Mac operating system that’s designed to protect most system locations, system processes, and Kernel extensions from being written to, modified, or replaced. Mac Protector is a fake rogue anti-spyware program that for the Mac OS operating system. This infection is spread through the use of advertisements on web sites that pretend to be fake online.

The other hole we found in some of these tools is that basic firewalls simply allow or block traffic passing through your network ports. But some programs offer another level of protection—intrusion detection. They examine incoming traffic to see whether it’s doing anything unusual and warn you if they detect anything suspicious. IPNetSentryX and NetBarrier are the only programs we looked at that have intrusion-detection tools.

While these programs are similarly skilled in protecting your Mac, they differ in ease of use. While each one lets you specify which network ports you want to block or leave open, NetBarrier and Norton make it particularly simple; IPNetSentryX, on the other hand, requires some advanced network knowledge to set up properly.

And each of these apps provides some kind of reporting system, from basic text documents that log access attempts to e-mailed notifications.

Macworld’s buying advice

When it comes to keeping snoops out of your Mac, OS X’s firewall is all most users really need. It’s safe, secure, and free. But its interface is awfully basic; for any advanced configuration, you’ll have to head to Terminal.

Intego’s NetBarrier X4 gets our nod as the best OS X firewall, thanks to its ease of configuration, boatload of useful features, and excellent documentation. Norton Personal Firewall and DoorStop X Security Suite are also excellent options but offer fewer features. I personally like (and use) Flying Buttress. But its lack of consistent support and its limited documentation make it a poor choice for the average user.

IPNetSentryX is in a class all its own. It’s an intrusion-detection program that’s really designed for network professionals who know what to look for on their networks and who have a thorough knowledge of TCP, UDP, and IP. If you’re wondering what I’m talking about, IPNetSentryX is not for you. But if you’ve just begun to salivate, it will be a powerful addition to your network security toolbox.

A phishing scam has targeted Mac users by redirecting them from legitimate websites to fake websites which tell them that their computer is infected with a virus. The user is then offered Mac Defender 'anti-virus' software to solve the issue.
This “anti-virus” software is malware (i.e. malicious software). Its ultimate goal is to get the user's credit card information which may be used for fraudulent purposes.
The most common names for this malware are MacDefender, MacProtector and MacSecurity.

Apple released a free software update (Security Update 2011-003) that will automatically find and remove Mac Defender malware and its known variants.
The Resolution section below also provides step-by-step instructions on how to avoid or manually remove this malware.
