Understanding the CISSP Challenge
The CISSP is not like other IT certifications. It tests your ability to think like a security manager, not a technician. Here's what makes it unique:
- CAT format: 125-175 questions in 4 hours (adaptive testing)
- Passing score: 700 out of 1000
- 8 domains: Covering all aspects of information security
- Experience required: 5 years in 2+ domains (or 4 years with degree)
Critical Mindset Shift
The CISSP tests you as a RISK ADVISOR, not a technician. The best technical answer is often wrong. Always choose what protects the organization while enabling business objectives.
