CSSLP Mind Map
All 8 Domains. Every Topic. Zero Cost.
The most comprehensive free CSSLP study resource available — covering all 8 exam domains, every key concept, and the exam traps that catch retakers out. Built for developers and architects preparing for the Certified Secure Software Lifecycle Professional exam.
This free CSSLP study guide covers all 8 domains of the CSSLP exam in a single interactive CSSLP mind map. Whether you are preparing for your first attempt or retaking after a failed exam, this tool breaks down every topic, sub-group, and concept the exam tests — with exam traps highlighted throughout.
The CSSLP covers 8 domains, each weighted differently in the exam. Secure Software Requirements, Secure Software Architecture and Design, Secure Software Implementation, and Secure Software Testing each carry 14% — together accounting for more than half the exam. These four domains represent the core of the secure software development lifecycle and deserve proportionally more study time. Secure Software Deployment, Operations and Maintenance carries 12%, with Secure Software Lifecycle Management, Secure Software Supply Chain, and Secure Software Concepts rounding out the exam at 11%, 11%, and 10% respectively.
Understanding how the CSSLP domains connect — and how the exam approaches secure development as an end-to-end discipline rather than a collection of individual controls — is what separates candidates who pass from those who retake. The exam rewards integrated thinking: security requirements that drive threat models, threat models that shape architecture, architecture that constrains implementation, and implementation that is tested against the original threat model.
Created by Actions On Cyber to give the CSSLP community a free, practical alternative to expensive study materials. Practical Guidance. Real Protection.

Frequently asked questions about the CSSLP exam
What are the 8 CSSLP domains?
The 8 CSSLP domains are: Secure Software Concepts (10%), Secure Software Requirements (14%), Secure Software Architecture and Design (14%), Secure Software Implementation (14%), Secure Software Testing (14%), Secure Software Lifecycle Management (11%), Secure Software Deployment, Operations and Maintenance (12%), and Secure Software Supply Chain (11%). This free CSSLP mind map covers all 8 domains in full.
How hard is the CSSLP exam?
The CSSLP is a challenging certification for software developers and architects with security responsibilities. It uses Computer Adaptive Testing and tests practical application of secure development practices across the full software lifecycle. Candidates without real development experience find it significantly harder — the exam expects you to think like a developer who has internalised security, not a security professional who has read about development.
CSSLP vs CISSP — which should I get?
The CSSLP is the right choice if you work in software development, software architecture, or application security. It tests deep knowledge of the secure SDLC — from requirements through deployment and supply chain. The CISSP covers a broader security management scope including physical security, network security, and risk management at CISO level. Many application security practitioners hold both — CISSP for breadth, CSSLP for depth in software security.
How long does it take to study for CSSLP?
Most candidates study for 3 to 5 months. Experienced developers who already practise secure development may need less time. The most common gaps are in the governance, lifecycle management, and supply chain domains — which experienced developers sometimes underestimate because they are less technically focused. Every domain contributes to the exam.
What are the CSSLP requirements?
The CSSLP requires a minimum of four years of cumulative paid work experience in one or more of the eight CSSLP domains, with at least one year in software development or a related field. Candidates who pass the exam without meeting the experience requirement become Associates of ISC2 until the requirement is satisfied. An accredited degree in a relevant field can substitute for one year of experience.
Is the CSSLP worth it?
The CSSLP is valuable for developers moving into security roles, application security engineers, and security architects. It demonstrates a structured understanding of secure development that goes beyond the OWASP Top 10. In organisations that take software security seriously — financial services, healthcare, government, and enterprise SaaS — CSSLP holders command a meaningful salary premium and are sought after for senior application security roles.
How do you pass the CSSLP exam?
The key shift is thinking as a security-aware developer and architect — not as a security auditor. The exam rewards answers that integrate security throughout the development lifecycle and apply controls at the most effective point in the process. The most common mistake is approaching it as a management certification like the CISSP — the CSSLP expects practical knowledge of how to build secure software, not just governance principles. Study all 8 domains and practise applying concepts to real development scenarios.
What is CSSLP?
CSSLP stands for Certified Secure Software Lifecycle Professional. It is an advanced ISC2 certification that validates expertise in integrating security throughout the entire software development lifecycle — from requirements and design through implementation, testing, deployment, and supply chain. It is the recognised gold standard for application security and secure development professionals worldwide.
What is CSSLP certification?
The CSSLP certification is an ISC2 credential covering 8 domains of the secure software development lifecycle. It requires four years of relevant work experience and a computer adaptive exam. It is aimed at software developers, architects, and application security engineers who want to formally demonstrate their ability to build security into software from the ground up — not bolt it on afterwards.
