Course Description
I have built this course to serve as the final, critical step in your journey to becoming a Certified Information certified information systems security professional exams (CISSP). With a massive bank of 1,500 original practice questions, I provide the deep technical and managerial drill-down needed to handle the 250-question marathon.
The CISSP isn't just about technical knowledge; it's about thinking like a risk manager. Every question in this set includes a comprehensive explanation for every choice. I explain why the correct answer is the best "managerial" choice and why the distractors are incorrect, ensuring you develop the "CISSP mindset" required to achieve the 700/1000 passing score on your first attempt.
Sample Practice Questions
Question 1: Which of the following is the primary goal of a Business Impact Analysis (BIA) within the Security and Risk Management domain?
A. To identify and prioritize critical business functions and their recovery requirements.
B. To install the latest firewall firmware across all corporate branch offices.
C. To perform a vulnerability scan on the web server to find SQL injection flaws.
D. To encrypt all data at rest using AES-256 bit encryption keys.
E. To draft a nondisclosure agreement for new third-party vendors.
F. To conduct a physical security sweep of the data center.
Correct Answer: A
Explanation:
A (Correct): The BIA’s fundamental purpose is to determine the impact of a disruption and identify the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for critical processes.
B (Incorrect): This is a technical operation, not a strategic analysis goal.
C (Incorrect): This falls under security testing, not impact analysis.
D (Incorrect): Encryption is a technical control for asset security.
E (Incorrect): This is a legal/administrative control, not the primary goal of a BIA.
F (Incorrect): Physical sweeps are part of site security operations.
Question 2: In the context of Identity and Access Management (IAM), which concept describes the "least privilege" principle?
A. Users should have access to all folders to ensure they can finish their work quickly.
B. Users are granted only the minimum access levels necessary to perform their job functions.
C. All employees should have administrative rights to reduce IT support tickets.
D. Passwords must be at least 25 characters long and changed every week.
E. Using a single shared account for the entire marketing department.
F. Granting access based solely on the seniority or age of the employee.
Correct Answer: B
Explanation:
B (Correct): Least privilege minimizes the attack surface by ensuring accounts have no more power than required for their specific tasks.
A (Incorrect): This describes excessive privilege and increases risk.
C (Incorrect): Providing universal admin rights is a major security violation.
D (Incorrect): This is a password complexity policy, not the definition of least privilege.
E (Incorrect): Shared accounts violate accountability and the principle of least privilege.
F (Incorrect): Access should be based on "need to know" and job role, not seniority.
Question 3: During the Secure Software Development Lifecycle (SDLC), at what stage is it most cost-effective to identify and mitigate security vulnerabilities?
A. During the Operations and Maintenance phase.
B. During the Deployment phase.
C. During the Requirements and Design phase.
D. After a major data breach has occurred.
E. During the disposal of the software.
F. When the software is being sold to a third party.
Correct Answer: C
Explanation:
C (Correct): Identifying flaws during the design phase (shifting left) is exponentially cheaper than fixing them once the code is written or deployed.
A (Incorrect): Fixing bugs in production is costly and risky.
B (Incorrect): Deployment is too late to catch fundamental architectural flaws.
D (Incorrect): This is the most expensive time to find a flaw.
E & F (Incorrect): These stages are too late in the lifecycle to influence secure coding efficiency.
