What is CISSP?
The Certified Information Systems Security Professional (CISSP) is the world's most recognized cybersecurity certification, issued by (ISC)². Unlike entry-level security certifications, CISSP is designed for experienced security professionals in management and senior technical roles.
CISSP validates expertise across eight security domains and is often required for senior cybersecurity analyst positions, security management roles, and government security clearance positions. The certification is DOD 8570 approved and recognized globally as the gold standard for security professionals.
- Global Recognition: Accepted worldwide as the premier security certification
- Career Advancement: Required or preferred for most senior security roles
- High Barrier to Entry: 5 years experience requirement filters for serious professionals
- Salary Premium: $15,000+ average salary increase over non-certified peers

CISSP Experience Requirements
CISSP has strict prerequisites that cannot be waived. You must have 5 years of cumulative, paid, full-time work experience in information security across at least 2 of the 8 CISSP domains.
| Scenario | Experience Required | Education Credit | Total Years |
|---|---|---|---|
| High School Graduate | 5 years security work | None | 5 years |
| Bachelor's Degree | 4 years security work | 1 year credit | 4 years |
| Master's Degree | 4 years security work | 1 year credit | 4 years |
| PhD | 4 years security work | 1 year credit | 4 years |
Important: You can take the CISSP exam without meeting the experience requirement and become an Associate of (ISC)² CISSP. However, you won't receive full CISSP certification until you document the required experience and get endorsement from a current CISSP holder.
- Experience must be paid, full-time work (part-time counts proportionally)
- Internships and co-ops count if they're paid security roles
- Military security experience counts toward the requirement
- Experience must span at least 2 of the 8 CISSP domains
The 8 CISSP Domains
CISSP covers eight domains of cybersecurity knowledge. Your experience must span at least 2 domains, and the exam weights each domain differently.
| Domain | Focus Area | |
|---|---|---|
| 1. Security and Risk Management | 15% | Governance, risk assessment, compliance |
| 2. Asset Security | 10% | Data classification, handling, retention |
| 3. Security Architecture and Engineering | 13% | Secure design principles, security models |
| 4. Communication and Network Security | 13% | Network protocols, attacks, secure communications |
| 5. Identity and Access Management | 13% | Identity lifecycle, access controls, authentication |
| 6. Security Assessment and Testing | 12% | Vulnerability assessments, penetration testing |
| 7. Security Operations | 13% | Incident response, logging, monitoring |
| 8. Software Development Security | 11% | SDLC, application security, secure coding |
CISSP Exam Details
The CISSP exam is adaptive (CAT format), meaning question difficulty adjusts based on your performance. You'll face 100-150 questions in 3 hours, or up to 250 questions in 6 hours if the system can't determine your competency level.

Study Timeline & Resources
CISSP preparation typically requires 6-12 months of dedicated study, even for experienced security professionals. The exam tests application of knowledge, not memorization, requiring deep understanding of security principles.
CISSP Study Plan (6-12 Months)
Month 1-2: Foundation Building
Read official (ISC)² CISSP Study Guide cover to cover. Focus on understanding, not memorization. Take notes on concepts you don't fully grasp.
Month 3-4: Video Training
Watch comprehensive video course (Cybrary, InfoSec Institute, or Kelly Handerhan). Videos help explain complex concepts that reading alone might miss.
Month 5-6: Practice Questions
Begin practice questions daily. Use Boson ExSim, (ISC)² practice tests, and CCCure. Focus on understanding rationales, not just memorizing answers.
Month 7-8: Weak Area Review
Identify domains where you score poorly on practice tests. Deep dive into those areas with additional reading and hands-on practice.
Month 9-10: Intensive Practice
Take full-length practice exams weekly. Aim for consistent 80%+ scores across all domains before scheduling your exam.
Month 11-12: Final Preparation
Review (ISC)² Code of Ethics. Take final practice exams. Schedule exam only when consistently scoring 85%+ on practice tests.
Essential Resources:
- Official Study Guide: (ISC)² CISSP Official Study Guide (Sybex) - $50-70
- Practice Questions: Boson ExSim ($99) or CCCure ($39/month) - essential for success
- Video Training: Kelly Handerhan (Cybrary), Thor Pedersen (Udemy) - $30-50
- Bootcamp: Consider CISSP training bootcamps for intensive preparation
CISSP Salary Impact
CISSP certification correlates with significant salary increases, though the 5-year experience requirement means causation is complex. The certification often enables promotion to senior roles that require CISSP.
