ISC2 CSSLP Exam Content Outline
Secure Software Concepts
Core security principles (CIA, least privilege, defense in depth), risk management fundamentals, regulatory compliance (GDPR, HIPAA, SOX, PCI-DSS), and secure design principles (fail-safe defaults, economy of mechanism)
Secure Software Lifecycle Management
SDLC methodologies (Waterfall, Agile, DevOps, DevSecOps), security integration into development lifecycle, security artifacts (requirements, threat models, test plans), and project management security considerations
Secure Software Requirements
Functional and non-functional security requirements, use cases and abuse cases, privacy requirements (data minimization, consent), and data classification and handling requirements
Secure Software Architecture and Design
Threat modeling methodologies (STRIDE, PASTA), attack surface analysis, secure design patterns, security controls selection (preventive, detective, corrective), and cryptography in design (key management, PKI)
Secure Software Implementation
Secure coding standards (OWASP, CERT), input validation, authentication and authorization (MFA, RBAC, OAuth), session management, error handling, memory safety, and code review processes
Secure Software Testing
Security testing methodologies, SAST/DAST/IAST, Software Composition Analysis (SCA), fuzz testing, penetration testing approaches, and vulnerability assessment vs penetration testing
Secure Software Deployment, Operations, Maintenance
Secure deployment practices (immutable infrastructure, blue-green), configuration management and hardening, patch management, vulnerability management, incident response, logging/monitoring (SIEM), and end-of-life planning
Secure Software Supply Chain
Supply chain risks (malicious code, typosquatting), third-party software risks, Software Bill of Materials (SBOM), software integrity verification (code signing, reproducible builds), vendor assessments, and open source security

Frequently Asked Questions
What are the CSSLP experience requirements?
CSSLP requires 4 years of cumulative, paid work experience in the Software Development Lifecycle (SDLC) in one or more of the 8 CSSLP domains. A 4-year college degree in computer science, information technology, or a related field waives 1 year of experience. Candidates without the required experience can pass the exam and become an Associate of ISC2, then upgrade to CSSLP after gaining experience.
What is the CSSLP exam format?
The CSSLP exam uses Computerized Adaptive Testing (CAT) with 125 questions to be completed in 3 hours. The passing score is 700 out of 1000 (70%). The exam consists of multiple-choice questions. CAT adapts question difficulty based on your performance, providing a more efficient assessment. The exam covers 8 domains with varying weights from 10% to 15%.
Who should get the CSSLP certification?
CSSLP is designed for software development professionals including: Software Developers and Engineers, Software Architects, Application Security Specialists, QA Testers and Test Managers, Project Managers in software development, Security Analysts working with software, DevOps Engineers, and Technical Leaders. It is ideal for anyone involved in building secure software or managing secure development processes.
How does CSSLP differ from CISSP?
While both are ISC2 certifications, CSSLP focuses specifically on secure software development across the entire SDLC, whereas CISSP covers broader information security management across 8 domains. CSSLP requires 4 years of SDLC experience vs CISSP's 5 years in general security. CSSLP is for software professionals who build applications, while CISSP is for security professionals who protect organizations. Many professionals hold both certifications for complementary expertise.
What is the CSSLP salary outlook?
According to industry surveys, CSSLP holders command competitive salaries in the software security field. Application Security Engineers typically earn $120K-$180K, Software Security Architects $140K-$200K+, and DevSecOps Engineers $130K-$190K. CSSLP certification demonstrates specialized expertise that employers value for secure development roles, often resulting in 10-15% higher compensation compared to non-certified peers in similar positions.
How should I study for the CSSLP exam?
Focus on understanding security integration at each SDLC phase: 1) Study threat modeling methodologies (STRIDE, attack trees); 2) Learn secure coding practices and common vulnerabilities (OWASP Top 10, CWE/SANS Top 25); 3) Understand testing approaches (SAST, DAST, fuzzing); 4) Review supply chain security (SBOM, dependency management); 5) Practice with 200+ exam questions covering all 8 domains.
