About this certification
The Kubernetes and Cloud Native Security Associate (KCSA) is a pre-professional certification designed for candidates interested in advancing to the professional level through a demonstrated understanding of foundational knowledge and skills of security technologies in the cloud native ecosystem. It is an entry-level credential that proves you have the baseline security knowledge needed to secure Kubernetes clusters and cloud native applications.
The exam covers a broad range of topics, including the 4Cs of cloud native security, Kubernetes cluster component security, Kubernetes security fundamentals, threat modeling, platform security, and compliance frameworks. By earning the KCSA, you demonstrate to employers that you understand the core security concepts and best practices essential for protecting modern cloud native environments. This certification is vendor-neutral, offering career flexibility and industry-wide recognition.
Who it’s for
The KCSA is ideal for individuals who are new to cloud security and want to start their career in this field. It is designed for candidates with little to no experience, providing a solid foundation in cloud native security concepts. Whether you are a student, a developer, or an IT professional looking to pivot into security, the KCSA offers a clear path to building your expertise. This certification is also valuable for those who work with Kubernetes and cloud native technologies and want to deepen their understanding of security. It is a great starting point before pursuing more advanced certifications like the Certified Kubernetes Security Specialist (CKS).
Recommended experience
While there are no mandatory prerequisites, the Linux Foundation recommends that candidates have some familiarity with Kubernetes and cloud native concepts. The free Introduction to Kubernetes course and the Kubernetes & Cloud Native Essentials course are excellent resources to build foundational knowledge before attempting the exam. Basic understanding of Kubernetes architecture and components; Familiarity with cloud native ecosystem and containerization; Awareness of fundamental security concepts (e.g., authentication, authorization, network policies)

Questions people ask
How does the KCSA relate to the Certified Kubernetes Security Specialist (CKS) certification?
The KCSA is a pre-professional certification that serves as a stepping stone to the CKS. While the CKS requires the CKA credential and focuses on advanced security skills, the KCSA provides the foundational security knowledge needed to pursue the CKS. Many candidates take the KCSA before attempting the CKS.
Do I need to earn a lower-level certification before taking the KCSA?
No, there are no prerequisites for the KCSA exam. You can take it directly, even if you have no prior certifications.
Can I take the KCSA exam online?
Yes, the KCSA exam is delivered online and is proctored. You can take it from your own location, provided you meet the technical and environmental requirements.
What is the retake policy for the KCSA exam?
The KCSA exam includes two exam attempts. If you fail the first attempt, you can retake the exam once. The specific waiting period between attempts is outlined in the Candidate Handbook.
Are there any hands-on labs or performance-based tasks in the KCSA exam?
No, the KCSA exam is a multiple-choice exam. It does not include hands-on labs or performance-based tasks.
What job roles does the KCSA certification map to?
The KCSA is designed for individuals pursuing careers in cloud security, including roles such as security analyst, cloud security associate, and Kubernetes security specialist. It is also beneficial for developers and operations professionals who want to enhance their security knowledge.
Can I recertify by passing a different Linux Foundation exam?
The KCSA certification is valid for 2 years. To renew, you may need to retake the KCSA exam or complete approved continuing education. Passing a higher-level certification like the CKA or CKS may also count toward renewal, but you should check the latest renewal policy.
Is the KCSA available in languages other than English?
The KCSA exam is currently offered in English. The Linux Foundation may add other languages in the future, but no other languages are officially listed at this time.

This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.

BFacial recognition

DObject detection
Look at the five steps. Detect finds a face, align straightens it, encode turns it into numbers, search compares it with a stored face, and decide answers one question: is this the same person? Classification would only say “a face”. Detection would only draw a box. Neither decides whose.
Then the page shuts, and it starts counting
The same questions come back with the book closed — that run is the one that counts. After it, your coach picks one thing for tonight, sized to the time you have, and brings pages back before you lose them.
