Difficulty Comparison: CISSP vs Security+
When comparing difficulty, the CISSP is rated very hard while the Security+ is considered moderate-hard. This difference reflects the depth and breadth of knowledge each exam tests.
The CISSP exam consists of 100–150 (adaptive) questions with a passing score of 700/1000. Candidates typically need 3–6 months study of dedicated preparation to feel confident on exam day.
The Security+ exam features Up to 90 questions with a passing threshold of 750/900. Most candidates invest 2–4 months study in preparation, though this can vary based on prior experience and study habits.
Both exams reward consistent, structured study. Practice tests are particularly valuable for building familiarity with question formats and identifying knowledge gaps before test day.
Salary and Career Outlook
Career earnings are a major factor when choosing between certifications. CISSP holders can expect to earn $110,000–$150,000 annually, while Security+ credential holders typically earn $65,000–$85,000.
These figures represent national averages and can vary significantly based on location, years of experience, industry sector, and additional certifications held. Metropolitan areas and specialized roles often command premium salaries.

Sample CISSP - Certified Information Systems Security Professional Practice Questions
Try these questions from our free CISSP - Certified Information Systems Security Professional practice tests. The correct answer and an explanation follow each question.
Which security model uses a lattice structure to define information flow between security levels?
- A. Graham-Denning model
- B. Bell-LaPadula model
- C. Biba model
- D. Chinese Wall model
Answer: B. Bell-LaPadula model
Bell-LaPadula uses a lattice of security classifications to enforce mandatory access controls based on confidentiality.
The “State Machine Concept” security model stipulates that a system must be secure in all of its states (Startup, Function, and Shutdown) or it will not be secure. This requirement demands responding to security events in order to prevent further compromises. What security aspect is exemplified by this way of response?
- A. Closed Design
- B. Trusted Recovery
- C. Least Privilege
- D. Open Design
Answer: B. Trusted Recovery
To proactively reduce the chance of an attacker gaining network access and sniffing data, the best strategy involves implementing preventative network security measures. Disabling unused switch ports and implementing MAC filtering prevents unauthorized devices from physically connecting. Additionally, software restriction policies prevent attackers from installing unauthorized sniffing tools. This combination directly addresses the threat at multiple layers, making it highly effective and preventative.
Which of the following hash algorithms is considered cryptographically broken and should NOT be used for security purposes?
- A. SHA-256
- B. SHA-3
- C. MD5
- D. SHA-512
Answer: C. MD5
MD5 is cryptographically broken; practical collision attacks have been demonstrated, making it unsuitable for digital signatures or certificate integrity.
Which documentation is essential when working with communication and network security in CISSP?
- A. Only verbal notes
- B. Detailed technical specifications and as-built diagrams
- C. Marketing materials
- D. General descriptions without specifics
Answer: B. Detailed technical specifications and as-built diagrams
Detailed technical specifications and as-built diagrams provide the accurate reference information needed for maintenance and troubleshooting.
