✍️ Sample CISSP Questions & Answers
1. Which access control model is BEST suited for a military environment where data classification levels (Top Secret, Secret, Unclassified) govern information access?
MAC enforces access based on data classification labels and subject clearance levels, making it ideal for environments with strict classification hierarchies.
2. A legacy application uses MD5 to hash passwords. What is the PRIMARY cryptographic concern?
MD5 is cryptographically broken, susceptible to collision attacks and extremely fast brute-force cracking, making it unsuitable for password hashing.
3. An organization wants to test its incident response procedures without disrupting production systems. Which exercise type is MOST appropriate?
A tabletop exercise walks participants through a simulated scenario verbally without activating actual systems or recovery procedures.
4. What is the PRIMARY security concern with using shared credentials among multiple administrators?
Shared credentials eliminate individual accountability, making it impossible to audit which specific person performed administrative actions.
5. Which skill is most critical for effective security and risk management?
Communication and stakeholder engagement are essential because management success depends on effectively coordinating with and influencing others.
6. What distinguishes a Business Continuity Plan (BCP) from a Disaster Recovery Plan (DRP)?
The BCP is broader, covering how the business continues to operate during a disruption, while the DRP specifically addresses IT and infrastructure restoration.
