The CISSP exam tests candidates across 8 knowledge domains - from governance and risk management through software development security - with each domain carrying a specific percentage weight that determines how many questions you'll face on exam day. Understanding which domains carry the most weight and where most candidates fail is the foundation of intelligent CISSP preparation.
This guide breaks down all 8 domains: what each one covers, how much weight it carries, how many study hours to allocate, and the key sub-topics that appear most frequently on the exam.
