Why is Apple’s Mac OS X so much more secure than Microsoft’s Windows?

BBC News “ClickBack” program’s online column answers questions and comments from viewers on technology matters:

Henry Winckelmann from Oxford said:
I’m disappointed, but not particularly surprised, to see you reporting on potential security issues on the yet to be released Windows Vista. Isn’t it true to say that any such piece which does not refer to secure operating systems with a proven track record (such as Mac OS X) is simply encouraging ignorance in the computer-using population? Shouldn’t you at least state the obvious, namely that there are wildly better, well proven alternatives to the feature-poor, insecure code which finds its way out of Microsoft?

BBC’s ClickBack:
Welcome to the age-old argument about which is more secure – Windows, Linux or OSX.

Henry, if you are saying that Mac OSX has had less security attacks than Windows, then you are absolutely right. No-one has ever denied that.

The question has always been: Why? Is it because it is more secure? Or is it because fewer people try to hack Apple?

All the security experts we have spoken to say the same thing – whilst OSX is a beautiful piece of software, it is still a highly sophisticated operating system, and it still receives regular security patches, just like Windows.

Apple only has small percentage of the market, tiny compared to Microsoft, and the logic is that if you are going to write a piece of malware that goes after the most people, do you write it for OSX, which, according to Apple, has around 15 million users, or do you go for Windows, which, depending on whose numbers you use, has anything up to a billion users?

I think it is a fair argument.

MacDailyNews Take: Note first that ClickBack did not answer Mr. Winckelmann’s central question, to paraphrase, why did their report on personal computer security fail to mention the most secure PCs, Apple Macs?

Now, in their response, ClickBack asks whether Mac OS X is inherently more secure OR is Mac OS X more secure because fewer people try to hack it. The response is flawed. The real answer is quite simple: Mac OS X is inherently more secure AND Mac OS X is secure because fewer people try to hack it.

There are 19 million Mac OS X users according to Apple (Steve Jobs, WWDC 2006), not 15 million as ClickBack states. Regardless, this is certainly a smaller number than Windows users, but it is not a small number by any stretch of the imagination. The only small number is the number of Mac OS X viruses in the wild that have affected Mac OS X users: zero (0). The absence of a single virus, for over five years of Mac OS X’s existence, proves the platform’s inherent security. It is not without flaws, however: flaws that Apple routinely fixes before they affect users. Since fewer hackers are looking to exploit Mac OS X (and because Mac OS X’s Unix foundation is time-tested by decades of use), Mac OS X users are even safer.

Windows suffers such massive and ongoing security woes for the inverse reasons that Mac OS X avoids such issues: Windows is inherently insecure and Windows is insecure because many people try to hack it.

By design, Mac OS X is simply more secure than Windows. For reference and reasons why Mac OS X is more secure than Windows, read The New York Times’ David Pogue’s mea culpa on the subject of the “Mac Security Via Obscurity” myth here.

  1. As more Macs get sold, this argument will finally die. Didn’t Apple take 12% of laptop sales? That’s not exactly a small market.

    Give it time. They’ll be swallowing crow.

  2. what i sent to click back :

    In light of the BBC’s recently heralded ‘partnership’ with Microsoft, it is dubious that the Beeb is entirely impartial when it comes to software. Therefore, the response the Henry Winckelman’s question not only does not answer his question, it is also biased and has no facts to back up the assertion that other operating systems are less prone to attack because there are fewer instances of them. Five minutes research will tell you that the way operating systems are put together determines their security reliability, not how many people use them.

    MW : half as in the BBC’s half-arsed non-answer

  3. Think about it for a second. If I were a cracker who wrote viruses to bring down servers and machines I would go after Apple for nothing more for exposure of being the first to do it. Because Mac OS X is secure, its the most difficult chanellge. Its so secure that even the hackers use OS X. Heck have you been to defcon? Half the users are on Mac laptops. Even at linux conferences they are on Mac laptops. The whole article is misleading and confusing and it doesn’t even answer the question.

  4. If OSX had even one virus in the wild then you could begin to make the argument for the security through obscurity theory, it would be incredible flimsy but you could say that where there is one there is obviously potential for more.

    The fact is there have been none, zero, 0. Now of course, this doesn’t then rule out there ever being a virus but statistically there should be some. Apple has a percentage of the market, even if it small, they should account for a small percentage of the viruses. It wouldn’t matter if this percentage was so small that you would round it to zero but you should have to do the rounding.

    Vista has fewer users yet it has viruses, using the logic that the fewer people there are to target a product the less likely it is to have security problems, then it should have zero. Defenders of the SVO myth could argue that those users who targeted XP are more likely to target Vista because of it’s potential to have a bigger user base and after all using their own argument systems get targeted based on how much exposure their exploits will create. If that were to be the case, why would they disclose these threats so early and give Microsoft a chance to fix them before the world at large was likely to find out about it? They wouldn’t.

    The SVO argument has merit only in general terms, not absolute ones. The fact is that OSX has absolutely no viruses. It might in the future but as of now it has none. I switched a few years ago and have had no problems, even if I do in the future, I’m still fine now. Even if the SVO myth were to be true it would take millions more users and massive market share gains before OSX were likely to see problems. Therefore even if we were to concede that OSX isn’t fundamentally more secure, we can still say that if you use OSX now you’re unlikely to have problems for some time.

  5. Are the malware writers really after the maximum number of users possible or are they after notoriety? I think the latter. And, if so, hacking Mac OS would bring you more notoriety than hacking WIndows. Who can’t hack windows?

  6. Harryhood has it right. Hacker types live on noteriety. You’d think one of them would crash the “OS X is safer than Windows” party simply for the ego stroke (or maybe just to humiliate all those “smug” Apple users). As if they haven’t been challenged to do so already. Give me a break!

  7. Of course virus writers would try to be the first to crack OS X. Look at those two bozos from Security Works who faked a security hole in a driver to get at Mac users. Heck, one of the morons even insulted Mac users and their “smuggness.”

  8. i’m still waiting for all that malware and those security problems that we Mac users were promised eariler this year. remember all those warnings of doom? dire predictions of the imminent crash of Mac systems worldwide? all the Windows fanboys and Mac Haters gloating because the Mac platform was finally going to have A VIRUS? well, dammit… I’M STILL WAITING!! lordy knows i wanna go out and spend money on antivirus crapware. yeeeah… riiiiiight.

    as i’ve said before, when the Mac malware starts flyin’, call me. i can be reached at 867-5309.

  9. Well since ClickBack’s “experts” say that Mac OS X is only more secure than Windows because it’s not as popular, then I’m not interested in Mac OS X.

    If on the other hand Mac OS X were more secure than Windows because of some inherent design, then I would switch immediately (if not sooner).

    Therefore, I will stick with the sticking cesspool that is Windows.

    Bunch a fsking idiots!
