Hey guys!
Recently, I passed my very first cert, Security + CE (4/2017) and also right after that I passed CEH (6, 2017). Now, I have been thinking what cert should I go for next and I have decided to go for CISSP. Here is my biggest concern on where I need to start preparing for this cert. I heard that this is very hard test and I really want to well prepare for this cert. I have 3 years of experience doing Information System Security Analyst.
Here are some of my questions

;
1. Which book is best way to read currently?
2. Having Sec + and CEH, am I ready for CISSP or should I go for any other certs before CISSP?
3. How long do I need to study and prepare for this exam?
I really do appreciated your help!!!

Thank you!
