This practice test course is meticulously designed to prepare you for the Certified Information Systems Security Professional (CISSP) certification exam administered by (ISC)². With 1,500 rigorously crafted multiple-choice questions (MCQs), this course covers every critical domain of the CISSP Common Body of Knowledge (CBK), ensuring you gain the confidence and expertise needed to pass the exam on your first attempt. Each question includes a detailed explanation of the correct answer, reinforcing key concepts and addressing common misconceptions.

Unlike generic question banks, this course is structured into six logically organized sections that align with the CISSP exam’s weightings and real-world security practices. You’ll practice with questions that mirror the exam’s complexity, format, and focus areas, eliminating guesswork and building deep conceptual mastery.

What You’ll Cover: The 6 Core Sections

Security & Risk Management
Security Governance Principles, Compliance/Legal/Regulatory Issues, Risk Management Concepts, Threat Modeling, Business Continuity Planning, Professional Ethics, Security Policies

Asset Security & Operations
Information Classification, Data Handling Policies, Security Operations, Logging/Monitoring/SIEM, Incident Response, Disaster Recovery, Physical Security Controls

Security Architecture & Engineering
Security Models (Bell-LaPadula, Biba), Cryptography Fundamentals, PKI, Hardware/Software Security, Cloud Architecture, Environmental Controls

Communication & Network Security
Secure Network Design (Zero Trust, Segmentation), Network Protocols (TLS, DNSSEC), Wireless/IoT Security, Firewalls/IDS/IPS, Cloud Networking (SASE, VPCs)

Identity Management & Security Testing
IAM Fundamentals, Authentication Methods (MFA, Biometrics), Access Control Models (RBAC, ABAC), Penetration Testing, Vulnerability Assessment, Third-Party Risk

Software Development Security
Secure SDLC, OWASP Top 10, Web/Mobile Security, API/Microservices, Vulnerability Management, DevSecOps, Malware Analysis

Sample Practice Questions with Explanations

Question 1 (Security & Risk Management):
Which principle ensures that users are granted only the minimum permissions necessary to perform their job functions?
A) Separation of Duties
B) Least Privilege
C) Mandatory Access Control
D) Role-Based Access Control
Correct Answer: B
Explanation: Least Privilege is a foundational security principle requiring that users, processes, or systems operate with the minimal level of access—or permissions—needed to perform authorized tasks. This reduces the attack surface and limits potential damage from compromised accounts. While Role-Based Access Control (D) is a mechanism to implement least privilege, the principle itself is defined by "Least Privilege" (B). Separation of Duties (A) prevents fraud by dividing critical tasks among multiple users, and Mandatory Access Control (C) enforces system-wide policies based on labels.

Question 2 (Communication & Network Security):
Which protocol secures DNS resolution by digitally signing DNS records to prevent spoofing and cache poisoning?
A) DNS over HTTPS (DoH)
B) DNS over TLS (DoT)
C) DNS Security Extensions (DNSSEC)
D) DNSCrypt
Correct Answer: C
Explanation: DNSSEC (DNS Security Extensions) uses cryptographic signatures to authenticate DNS responses, ensuring data integrity and origin authenticity. It prevents attacks like DNS spoofing and cache poisoning by validating records against a chain of trust. DNS over HTTPS (A) and DNS over TLS (B) encrypt DNS queries to protect confidentiality but do not authenticate records. DNSCrypt (D) encrypts queries but lacks standardized adoption and does not provide full DNSSEC-level validation.

Question 3 (Software Development Security):
During which phase of the Secure Software Development Life Cycle (SDLC) should threat modeling be FIRST conducted?
A) Design
B) Requirements Gathering
C) Implementation
D) Testing
Correct Answer: B
Explanation: Threat modeling begins during Requirements Gathering to identify security objectives, potential threats, and attack vectors before design or coding starts. This proactive approach ensures security requirements (e.g., authentication, data protection) are defined early, reducing costly rework. Conducting it in Design (A) is common but suboptimal; delaying until Implementation (C) or Testing (D) misses critical opportunities to address architectural risks.
