I recently received in in-system private mail asking several questions about preparing for the CISSP exam. The questions themselves are likely to come to mind to many others, and there is no personal information in them. Thus, I am providing those questions and my answers here, to help others who may be concerned about the costs and steps to become certified.
1 - one of the pre-requisites that I read on ISC2 website is about proven past experience. So, when do I submit this proof? - before registering for exam or after?
DCS: You do not need to verify your cybersecurity experience until after you have passed the exam. Once (ISC)2 notifies you that you have passed (not the provisional passing score at the testing center), you must either have an existing g(ISC)2 member (fully certified) endorse you for certification, having reviewed and verified your experience history as you provide to his satisfaction, OR you must send your experience history statement ot the (ISC)2 office adn ask them to endorse you. DO the latter only if you do not have a member who knows you personally and can endorse you.
2 - As a proof - My manager is willing to give me letter with details - would that be suffice with my employment and salary letters?
DCS: you do not need to provide any salary information. However, a statement from your manager describing your information security experience, number of years performing the tasks, and organized according to the eight domains, can be used to either a local endorser or to the (ISC)2 staff.
3 - Can I appear for exam without the proof letter? or it is mandatory.
DCS: You can take the exam with absolutely on infosec experience. You should not do so; but you can. If you do pass the test with no experience, you have wasted your time and money, because you have only two years to get endorsed with 4 or 5 years of domain-specific infosec experience. Therefore, you should not take the exam until you have at least three years of experience.
4 - Finally, the cost of course - it’s about 7500 USD! - Do I really need that? or I can prepare on my own with official books and prepare for exam.
DCS: You are not required to take any preparation course. The only mandatory fee is for he exam itself. There are several ways to prepare, including online course, cooperative study groups. self-study, and the high cost intensive week-long classes. The 7500USD cost you refer is clearly for one of the official (ISC)2 or independent boot camp classes. You need not take that unless you really want to. Personally, I discourage such a class, unless you need it to focus your attention in one week. The reason for my recommendation is that such cram courses do not result in long term memory. Either multi-week cooperative study groups or even self study accordion to your own study plan will result in much better understanding and knowledge retention.
5 - if I avoid the course fee - I still need to arrange for 745 USD - for the CISSP exam. Is that correct understanding?
DCS: Yes, you will have to pay the fee for the exam, itself, and take the exam at a testing center.
