As the world is moving towards containerization, Kubernetes has become a go-to technology for deploying and managing containers. However, with the growing adoption of Kubernetes, the security risks associated with it have also increased. To address these security concerns, the Linux Foundation has introduced the CKS (Certified Kubernetes Security Specialist) certification. This certification is designed for Kubernetes administrators who want to demonstrate their expertise in securing containerized applications and Kubernetes platforms. In this article, we will discuss the exam objectives, exam details, and related books that can help a candidate pass their CKS exam.
Exam Objectives:
The CKS exam tests a candidate's proficiency in the following areas:
- Cluster Setup
- Cluster Hardening
- System Hardening
- Minimizing Microservice Vulnerabilities
- Supply Chain Security
- Monitoring, Logging, and Runtime Security
- Network Security
- Authentication, Authorization, and Access Control
Exam Details:
- Cost: The cost of the CKS exam is $300 USD.
- Passing Mark: To pass the exam, a candidate needs to score at least 66%.
- Time: The CKS exam is a 2-hour online proctored exam.
- Delivery Method: The CKS exam is delivered through the LF (Linux Foundation) training and certification platform.
- Format: The CKS exam consists of 17 performance-based tasks that require candidates to perform tasks related to Kubernetes security.
Who should take the exam?
The CKS exam is intended for Kubernetes administrators who want to demonstrate their expertise in securing containerized applications and Kubernetes platforms. Candidates who want to take this exam should have a solid understanding of Kubernetes architecture, networking, and security.
Prerequisites and Qualifications:
Candidates who want to take the CKS exam should have:
- One or more active Kubernetes certifications (CKA, CKAD, or CKS)
- Minimum of 2 years of experience in container technologies
- Minimum of 1 year of experience in Kubernetes
- Strong understanding of Kubernetes architecture, networking, and security
Related Books:
There are several books available that can help a candidate prepare for the CKS exam. Some of the recommended books are:
- Kubernetes Security by Liz Rice
- Kubernetes Best Practices by Brendan Burns
- Practical Kubernetes Security by Hacking and Securing Docker
- Cloud Native DevOps with Kubernetes by John Arundel
In conclusion, the CKS certification is a valuable certification for Kubernetes administrators who want to demonstrate their expertise in securing containerized applications and Kubernetes platforms. By passing the CKS exam, candidates can prove that they have the skills and knowledge required to secure Kubernetes environments. To prepare for the exam, candidates should have a strong understanding of Kubernetes architecture, networking, and security, and should use recommended books to supplement their studies.
In addition to using recommended books, candidates can also take advantage of various online resources such as Kubernetes documentation, online courses, and practice exams. The Linux Foundation also offers a CKS exam preparation course that covers all the exam objectives in detail and provides hands-on exercises to reinforce concepts.
To prepare for the CKS exam, candidates should also practice on a live Kubernetes cluster, as this will give them practical experience in securing Kubernetes environments. They should also familiarize themselves with various Kubernetes security tools such as Falco, Sysdig, and Aqua Security.
In conclusion, passing the CKS exam requires a solid understanding of Kubernetes architecture, networking, and security, as well as practical experience in securing Kubernetes environments. Candidates should use recommended books, online resources, and practice exams to supplement their studies, and practice on a live Kubernetes cluster to gain practical experience. By passing the CKS exam, candidates can demonstrate their expertise in securing containerized applications and Kubernetes platforms, and open up new career opportunities in the field of Kubernetes administration.
