I have 22 years of experience in the IT industry, more on Projects and account mgt.
My preparation was based on the recommendation from the community, here is the summary
Reading / Books
Study Groups: To keep you motivated and collective endeavor
- Some wonderful free stuff to cover simple to medium learning, https://learn.frsecure.com/enrollments, Some excellent leaders Ron, Chris, and their team of experts!
- Decent endeavor is good for beginners: https://www.skool.com/cissp/classroom
I would plan my reading early in the morning, as it takes the most focus to grasp the reading:
- OSG: Official study guide needs 50 Hours to complete
- Destination CISSP is a concise guide.
- Summary of OSG: very useful for light reading / refreshing knowledge, https://github.com/jefferywmoore/CISSP-Study-Resources?tab=readme-ov-fileVideo training (post reading books)
- DestinationCert https://www.youtube.com/@destcert along with Mindmap notes excellent for practice.
- Udemy Thor's lectures are good.
- Cybrary has free training.
- Cram Videos on the latest updates
Cheets sheets
