This course offers multiple mock exams to prepare for Certified Kubernetes Security Specialist (CKS) exam. Take into account that this course doesn't give access to any hands-on labs and is focused primarily on preparing for the exam from the theorical point of view.

Note - 1 : Prior knowledge of CKA is required before enrollment.

You must cover below curriculum before attempting CKS Exam:

10% - Cluster Setup

1. Use Network security policies to restrict cluster level access

2. Use CIS benchmark to review the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)

3. Properly set up Ingress objects with security control

4. Protect node metadata and endpoints

5. Minimize use of, and access to, GUI elements

6. Verify platform binaries before deploying

15% - Cluster Hardening

1. Restrict access to Kubernetes API

2. Use Role Based Access Controls to minimize exposure

   • handy site collects together articles, tools and the official documentation all in one place

3. Exercise caution in using service accounts e.g. disable defaults, minimize permissions on newly created ones

4. Update Kubernetes frequently

5. Minimize host OS footprint (reduce attack surface)

6. Minimize IAM roles

7. Minimize external access to the network

8. Appropriately use kernel hardening tools such as AppArmor, seccomp

15% System Hardening

1. Minimize host OS footprint (reduce attack surface)

2. Minimize IAM roles

3. Minimize external access to the network

4. Appropriately use kernel hardening tools such as AppArmor, seccomp

20% - Minimize Microservice Vulnerabilities

1. Setup appropriate OS level security domains e.g. using PSP, OPA, security contexts

2. Manage kubernetes secrets

3. Use container runtime sandboxes in multi-tenant environments (e.g. gvisor, kata containers)

4. Implement pod to pod encryption by use of mTLS

20% - Supply Chain Security

1. Minimize base image footprint

2. Secure your supply chain: whitelist allowed image registries, sign and validate images

3. Use static analysis of user workloads (e.g. kubernetes resources, docker files)

4. Scan images for known vulnerabilities

20% - Monitoring, Logging and Runtime Security

1. Perform behavioral analytics of syscall process and file activities at the host and container level to detect malicious activities

2. Detect threats within physical infrastructure, apps, networks, data, users and workloads

3. Detect all phases of attack regardless where it occurs and how it spreads

4. Perform deep analytical investigation and identification of bad actors within environment

5. Ensure immutability of containers at runtime

6. Use Audit Logs to monitor access

These mock exams are of intermediate to high complexity that will give you the required skills to master the CKS exam and include detailed explanations of the questions, as well as references to the official documentation.
