The CISSP Mindset Shift
The most common mistake candidates make is studying for CISSP like an IT exam. CISSP is NOT a technical exam — it tests you to think like a CISO or risk manager, not a network engineer. When in doubt, choose the answer that protects the business and manages risk at the highest level. Risk comes before everything else.
Key Tips
- ✓Always think: 'What would a risk-conscious manager do?'
- ✓When two answers are both technically correct, pick the one that comes first in the security process
- ✓Identify, then fix — always choose identifying the problem before implementing a solution
