I passed the ISSEP exam and must say that what I have heard about it being an extremely difficult exam holds true to me. This was the only (ISC)2 exam I've taken where I wasn't sure if I passed or not when I ended the exam. Thankfully, my folded-up paper said congratulations.
Below is a review of the ISSEP exam and my studies used to get there along with my assessment of things you really need to know to even stand a fair chance. It is a long one. Even though there are only four domains, there is an incredible amount of information you are expected to know. I apologize in advance if I leave anything out.
Resources used:
Official Guide to the ISSEP CBK (2005)
The actual documents themselves (covered in the ISSEP exam objectives and CBK)
The Official Guide to the ISSEP CBK (2005)
I found that the Official Guide to the ISSEP CBK (2005) was a very outdated, but, valuable asset. I read through the entire book, and revisited the Systems Engineering (SE) section many times for clarity. It is well-written and flows nicely. I don't think anyone should attempt this exam without it. There is supposedly a newer edition coming out in the near future. Note that once it comes out that it will likely mean the exam objectives have changed, since they are anticipating big changes and don't want to publish a new ISSEP book with a
short shelf life. Always pay attention to the most recent exam CIB for the exam you are going to attempt.
The Actual Documentation
It is important to note that preparing using the documentation itself is extremely valuable. There really isn't a substitute to reading and preparing using the actual documents. I wouldn't recommend attempting this exam without reading through the documents themselves and having a thorough understanding of each applicable one. However, if you are able to get through this daunting task, you will be well off and stand a good chance on this exam.
Review:
The objective of this review is to assist others who desire to prepare for and attempt this exam. For me, one of the most difficult parts of the preparation for the ISSEP was the fact that there is so little information out there about it and not many sources to pull from. Hopefully, this review will help change that. Enjoy!
C&A
One of the four domains of the ISSEP is C&A. My initial thought was to prepare for the CAP and pass that exam and that this would serve as preparation for this domain of the ISSEP. This assertion was correct and served extremely well for this domain. My review of the CAP itself can be found
here. One important thing to note, after taking both the CAP and ISSEP, is that the CAP did not seem to focus on NIACAP or DIACAP at all (only the RMF), while the ISSEP still includes all of the above. This caught me off guard on my exam, though I was able to at least power through the DIACAP questions and make good attempts on the NIACA questions thanks to my direct experience with DIACAP. If anyone is interested in taking the ISSEP, I highly recommend that you consider the CAP exam first and add studies of NIACAP and DIACAP as well. You should know the entire RMF inside and out and be able to identify any given activity or task as well as understand where it stands in relationship to other activities and tasks. You also need to know how it relates to the SDLC phases. These are all musts for both exams. If you do this, you will be prepared for the CAP and the C&A domain of the ISSEP.
Systems Engineering
Next, I will address the SE domain. This is, as you probably guessed, the bulk of it. As others before me have said, you must know the IATF inside and out or you simply will not pass. Similarly to the RMF, you must know it so well that you understand every single activity and task, how they relate to each other, how they support each other, what happens in each and every activity and task, as well as how to assess the effectiveness at each step and how that step supports C&A. I know it probably sounds difficult to master and dedicate to memory. That's because it is. It is possible though. You really do need to know it completely inside and out. However, if you do manage to know it on that level, you will be able to answer the questions effectively and confidently. It is also important to spend a good deal of time mastering the DoD Architectural Framework (AF) and the Defense Acquisition System (DAS).
USG IA Related Policies and Issuances
You also have to know the policies, laws, and regulations that apply. To keep this short, I will say that there are many on the list that I used to study and I did read through them all. Most of them I read through in their entirety, but, not all of them, and I still missed some documents that appeared on my exam. Here is a list you should study and know before your exam. Please note that this list is not all-inclusive and that you should extend your studies beyond this list to cover any additional documentation you feel is important to the ISSEP exam. I think this is everything, but, I apologize if I left anything out:

Technical Management
I only spent five hours reading through the technical management domain and skimmed through the DOD PMBOK. I recommend that you spend more time than this on this section if you are not familiar with it. This section is the shortest and least challenging of the domains, in my opinion.
Summary
To make a long story short, you need to spend a significant amount of time preparing for this exam and really know your stuff. There were many questions where I was only able to answer them due to my related work experience. I highly recommend you only take this exam if you truly have the experience to match the required knowledge. If you have the experience and spend ample time studying and preparing, you can be successful. The exam may have a really low pass rate, but, it is not impossible.
I believe that covers everything, but, I will add topics and items if I remember anything additional. Please feel free to comment or ask questions. I look forward to seeing and helping others who attempt this challenging exam. It is a very rewarding experience to conquer this one. On to the endorsement process, yet again!
At the time of this writing, only 915 people are ISSEP certified. I am hopeful that this number will grow as it gains more attention and recognition from the industry.
