Duration
14 hours (usually 2 days including breaks)
Requirements
- Previous experience working with Kubernetes
Audience
- DevOps engineers

Overview
Kubernetes offers features for securing a cluster and its applications. The out-of-the-box settings, however, may not provide full protection from hackers and unintentionally harmful actors.
This instructor-led, live training (online or onsite) is aimed at engineers who wish to secure a Kubernetes cluster beyond the default security settings.
By the end of this training, participants will be able to:
- Understand the vulnerabilities that are exposed by a default Kubernetes installation.
- Prevent unauthenticated access to the Kubernetes API, database, and other services.
- Protect a Kubernetes cluster from accidental or malicious access.
- Put together a comprehensive security policy and set of best practices.
Format of the Course
- Interactive lecture and discussion.
- Lots of exercises and practice.
- Hands-on implementation in a live-lab environment.
Course Customization Options
