ISC2 Certification Exam Prep

The CISSP (Certified Information Systems Security Professional) is the senior-level credential for cybersecurity practitioners. It is accredited under ISO/IEC 17024 and listed under DoD Manual 8570/8140 at IAM Level III, IAT Level III, and IASAE Level II — which is why it appears on so many federal and defense cybersecurity job postings.

The exam covers eight domains in the (ISC)² Common Body of Knowledge: Security and Risk Management, Asset Security, Security Architecture and Engineering, Communication and Network Security, Identity and Access Management, Security Assessment and Testing, Security Operations, and Software Development Security. The English-language exam uses Computerized Adaptive Testing (CAT), 100–150 questions in up to 3 hours.

Eligibility: five years of paid, full-time work experience in two or more of the eight domains (one year can be waived with a four-year degree or another approved credential like the CCSP or SSCP). Candidates without the experience yet can take the exam and hold Associate of (ISC)² status until they accrue the time.

Career value: CISSP-certified professionals in North America report an average salary around USD $150,000 in (ISC)² compensation surveys. The credential is required or preferred for security engineer, security architect, CISO, and federal cybersecurity roles. CISSP is fundamentally a managerial-level exam — it tests judgment across the security domains rather than hands-on tooling skill, so candidates who can think like a defender designing layered controls do best.
