I'll say up front that I failed the exam by a couple of questions. But this is not about my score: I don't need Security+ title for my job or any future career plans. I took the exam because I was excited about the title; I thought it would be useful to broaden my security knowledge in areas that I don't deal with on a regular basis.

From my experience in taking more than 100 other certification exams, I expected Security+ to ask unambiguous questions with varying levels of difficulty that when combined -- and let's face it, there are 100 questions here today, so there's lots of scope for this variation -- would give a reliable indication of whether someone has acquired basic security skills in a broad range of areas. And I don't think that's an unreasonable expectation to have, especially considering this exam's $225 (U.S.) price tag. (Even worse, in Australia the cost in local currency was $415, which equates to $312!).

Unfortunately, this is NOT the exam we have today.

Much of Security+ consists of pretty easy questions about security, which probably accounts for the relatively high percentage needed to pass (83 percent). -- not unreasonable considering how many easy questions there are. However, there's two other types of questions on this exam: a handful covering content so obscure that only an expert can answer, and -- here's the kicker! -- others that are so poorly worded that you are unable to determine what you are being asked, let alone which is the correct response! In fact, before I took the test, I had seen comments posted in forums complaining about the quality of the Security+ exam questions, and I pretty much dismissed those posters as whiners. But now I know they were on to something. I wish I could put detailed examples of these questions here; but that, of course, would be giving away exam questions, which I can't do.

Now, I'm not a psychometrician, so I can't say that the Security+ exam doesn't confirm to this testing standard or that one. But considering the quality of the questions asked and the imbalance of the question difficulty levels, I can say that I simply don't believe that this exam does what it sets out to do: truly test one's knowledge of the subject at hand.

I have a number of other CompTIA certifications: Network+, Server+, Linux+ and IT Project+. Security+ simply doesn't conform to the same standard. Therefore, until CompTIA does some work to fix the problems with this exam, I can't recommend that anyone else take it, and I will no longer recommend the program to others. I did learn a great deal about security in my preparation, but as far as the exam itself goes, I would have been much better off spending the cash on expanding my CD collection.

I'd like to hear back from those of you out there that have taken this exam. What do you think? Let me know by posting your comments below.
