I hope this note finds you well. I would like to know if you can provide advice regarding the right material to become CISSP certified. I am planning to take this certification at the end of the year.
This is a very broad question, and there is no one-size-fits-all approach. If you search this board, you can probably find many helpful suggestions and personal anecdotal experiences.
Personally, I would start with the latest official CBK, before you spend too much time and money on any other materials.
Best of luck,
Well this depends mostly on your style of learning, there's a hole bunch of material, just make sure to get the most recent as CBK was updated just last year.
Personally I find Sybex literature extremely clear and helpful, also Kelly Handerhan's Cybrary course is well paced and easy to follow.
Don't forget to answer as many practice tests as you can, that will help you to get into ISC2 mindset.
I wish you luck in your exam!
