Hi All - I recently failed the ISSEP exam (an expensive practice exam). I am new to DoD space but have worked in CIP space for years. I tried to read through NIST 800-160 and found that a tough read. I was familiar with every term on the exam but just didn't pass. I guess you may wonder what I am asking for here... I think some words of encouragement or tips.
There's a great post here which will give you some additional resources to study for the ISSEP:
At least two members from here (including me) used the list in that post to successfully pass the ISSEP fairly recently. A lot of them are NIST references, and, yes, they can be a tough read, but all the information you need to pass this exam is there.
Not sure, if this going to encourage you but it will hopefully inspire you... The ISSEP is the most exclusive of ISC2's certifications that aren't regionally focused, so it's very worthwhile persevering with so you can join the club!
Also some words of consolation... I heard from someone apparently in the know that only 30% of ISSEP exams result in a pass, so you're certainly not alone in not passing.
It's just a temporary set back, as most things others label 'failures' are. You reflect on what was difficult and were you could improve, go back, re-study and take it again. Don't be too hard on yourself I doubt it's an easy exam.
