Studying for CISSP

I have been studying to take the Certified Information Systems Security Professional (CISSP) exam. The CISSP is one of the world’s most valued information technology and information security certifications. Here are some valuable resources I have found in my preperation.

More about CISSP

The Exam

The CISSP exam is a challenging, 100 to 150-question marathon of a test taking up to three hours. The new CAT format can play physiological games with test takers as the questions vary in difficulty based on your previous submissions.

The CISSP isn’t the best option for every cybersecurity professional. Before you start down your certification path, make sure you aren’t missing an opportunity to pursue a certification more aligned with your immediate career goals.

Exam Cram Series

Pete Zerger is a Cybersecurity Strategist, Cloud Architect, Instructor, and Educator. Pete has an incredible CISSP Exam Cram series available with extensive and well-articulated videos. Pete also offers all presentations for download. 

I would highly recommend starting with Pete’s series, coupled with the Wiley Efficient Learning content and practice questions in the next section.


Wiley Efficient Learning

Official Study Guide and Practice Tests

The (ISC)2 CISSP Certified Information Systems Security Professional Official Study Guide 9th Edition (Also available on Kindle), is the official study guide for the CISSP exam. After purchasing the book (either hard / soft copy or Kindle edition), you can register for your free account on the Wiley Efficient Learning portal and start with your practice exams.

These practice exams are a great asset to help you prepare for the real exam and understand the missing gaps in your knowledge. 

Rinse and Repeat

Learn, Practice, Repeat

Probably the hardest and most time consuming part of the practice phase is to repeatedly attempt the practice tests and fill in any missing knowledge you have. The key here is to make sure you completely understand the content and topics; Do not just learn the questions and answers by heart as you will only be cheating yourself. Besides, the exam questions are not very similar to the practice tests so you may not be able to pass if you do not completely understand the content and topics.
