About this exam

The Certificate of Cloud Security Knowledge (CCSK) is a cloud security credential from the Cloud Security Alliance, described by CSA as the industry benchmark for cloud security expertise. CCSK v5 is aimed at IT professionals working in cloud computing, including security staff, developers, IT operations staff, audit and compliance professionals, sales and solution engineers, and product marketers. No official work experience or prior qualification is required, though a basic grasp of security fundamentals such as firewalls, secure development, encryption, and identity and access management helps. The exam is open-book, delivered online, and consists of 60 multiple-choice questions drawn randomly from a larger pool, to be completed in 120 minutes, with a minimum passing score of 80%. CCSK v5 covers 12 domains, from cloud computing concepts and architectures through governance, risk and compliance, identity and access management, security monitoring, infrastructure and networking, workload, data and application security, incident response and resilience, to related technologies and strategies. The curriculum adds emphasis on artificial intelligence and generative AI, Zero Trust, DevSecOps and CI/CD, automation, serverless workloads, and data lakes. Preparation options include a free CSA Prep Kit for self-study, online self-paced courses, and virtual or in-person instructor-led training, including a lectures-plus-labs format.

What you'll study

Common questions

About CCSK preparation

What is the exam format and how long do I have?

The CCSK exam is open-book and taken online. It contains 60 multiple-choice questions selected randomly from a larger pool, and you must complete it within 120 minutes. Because it is open-book, plan your time so you can look things up without losing pace on the 60 items.

What score do I need to pass?

The minimum passing score is 80%, so you need to answer roughly 48 of the 60 questions correctly. That leaves little margin for careless errors, which is why broad familiarity with all 12 domains beats deep expertise in only a few.

How much does the exam cost and do I get retakes?

Purchase of the Exam and Chatbot costs $445 and provides two test attempts, which you have two years to use. Budget your first attempt carefully so a second attempt remains available if you need it.

Do I need experience or prerequisites before taking it?

No official work experience or prior qualification is required. CSA notes it is helpful to have at least a basic understanding of security fundamentals such as firewalls, secure development, encryption, and identity and access management before you start.

What topics does the CCSK v5 cover?

CCSK v5 covers 12 domains: cloud computing concepts and architectures; cloud governance; risk, audit and compliance; organization management; identity and access management; security monitoring; infrastructure and networking; cloud workload security; data security; application security; incident response and resilience; and related technologies and strategies.

How should I prepare and in what order should I study?

CSA offers a free Prep Kit for self-study, plus online self-paced courses and virtual or in-person instructor-led training, including a CCSK Plus format with lectures and hands-on labs. A sensible order is to start with the free Prep Kit across all 12 domains, then revisit the weaker domains and take practice questions.

What is new in CCSK v5 compared with earlier versions?

CSA states v5 consolidates the content into 12 domains instead of 14, increases focus on cloud workloads including serverless and FaaS, expands application security, CI/CD, DevSecOps and automation, and strengthens governance, auditing, compliance, organizational security, IAM and incident response. AI and generative AI replaced the previous related technologies chapter, and Zero Trust is integrated across domains.

Who is the CCSK designed for?

It is designed for IT professionals working in cloud computing. CSA says security staff and other technical professionals, including developers, IT operations staff, audit and compliance professionals, sales and solution engineers, and product marketers, benefit from its well-rounded view of cloud security.

What common mistakes cause candidates to fail?

The 80% threshold and 120-minute limit punish shallow coverage, so relying on a single domain or skipping domains usually hurts. Treating the exam as trivially easy because it is open-book is also risky, since looking up every answer costs time. Study all 12 domains and practise timed questions.
