What I wish I knew before I took my CISSP exam
Aloha all,
As most of you who follow these threads know, I am one of the 'Third Time is the Charm' test takers and passers. Now, with 1.5 years as a certified CISSP and all-around general InfoSec preacher to the choir and the congregation, I can say that I now know that I would have passed the test the first time around if I had taken all of my US Government (Military, US Foreign Service, and various intelligence agencies) knowledge, and left to work in the private sector, specifically in the financial world.
Since 2006, the US DoD has pushed HARD for Information Security professionals to take and pass the CISSP, lest the professionals in question will forever remain mid-level 'grunts' most of their careers. So, I went into this test thinking (and hearing) that the exam was deeply rooted in US Military policies and practices; I'll be the first to tell you that a lot of that is true. If you have the benefit of working in the military or intel community, then you've covered a number of the domains. Unfortunately, DRP/BCP and SDLC are NOT heavily covered in the military or other, as so much of what I/we did was compartmentalized, meaning that while software development exists, as do life cycles of same, your exposure can be limited if you are not in a really senior role.
Then there's GLBA, ITIL, and ISO...Not really covered in the US military in the way you'd gain knowledge to pass the exam with hands-on experience. I work for Dell SecureWorks as a contractor for a major data analytic firm that has to follow all kinds of rules, to include GLBA, SOX, ISO, PCI-DSS, PII, etc.,. Even the way the help-desk ticketing systems are set up for operations such as this commercial/financial entity helps with understanding ITIL quite well, and never would have gained said knowledge had I stayed with the gov unless I took a help desk position again (worked too hard to get OUT of that arena to put myself back in it...Gawh how boring.)
Point is this: With the knowledge I've gained in the last 14 months alone, combined with the military and intel experience, I would knock the CISSP clear out of the park (cleared the Green Monster for you Boston fans) if I had to take it today. So my suggestion to you is this if you're in the government sector. Be comfortable with the knowledge you have gained from your employment with the government (US and other), but DEFINITELY take a lot of extra time to learn how the commercial, banking, and health industries work, otherwise this test will hurt you. I've seen a lot of my fellow military and contractor friends take this test and fail like I did for the same reasons I explained above.
And before you say it...I know the 'Catch 22.' It's hard to make the shift in careers without the CISSP, so I am not saying quit the government and work in commercial first. I am just saying that test would be much easier for me now, knowing what I know about government and private sectors.
