Kubernetes Security Fundamentals (LFS460)

Participants should have an understanding of Linux administration skills, comfortable using the command line. Must be able to edit files using a command-line text editor. Basic security knowledge.

Audience

This course is ideal for anyone holding a CKA certification and interested in or responsible for cloud security.

Experience Level: Intermediate

This instructor-led course provides skills and knowledge across a broad range of best practices for securing container-based applications and Kubernetes platforms during build, deployment, and runtime.

What you will learn?

This course exposes you to knowledge and skills needed to maintain security in dynamic, multi-project environments.

This course addresses security concerns for:

• cloud production environments
• covers topics related to the security container supply chain,
• topics from before a cluster has been configured through deployment, and ongoing,
• agile use, including where to find ongoing security and vulnerability information.

The course includes hands-on labs to build and secure a Kubernetes cluster, as well as monitor and log security events.

What you will gain?

This course is designed as preparation for the Certified Kubernetes Security Specialist (CKS) exam and will substantially increase students’ ability to become certified.
