Attacking and Auditing Docker Containers and Kubernetes Clusters

Madhu Akula

Abstract

This 3 day attack-focused, hands-on training will set you on the path to using common attack techniques against docker, kubernetes, containerized infrastructure. It will help you to learn the approach to follow andthe process for testing and auditing containers and Kubernetes clusters. By the end of the training participants will able to identify and exploit applications running on containers inside Kubernetes clusters witha hands-on approach.

An organization using micro services or any other distributed architecture rely heavily on containers and container orchestration engines like Kubernetes and as such its infrastructure security is paramount to its business operations. This course will set the base for security testers and DevOps teams to test for common security vulnerabilities and configuration weaknesses across containerized environments and distributed systems. It also helps to understand approach and process to audit the Kubernetes environment for security posture.

  • The focus is on the security aspects of application and the container infrastructure
  • The participants will learn the common tools and techniques that are used to attack applications running in containerized environments
  • The participants will be introduced to Docker, Kubernetes and learn to assess the attack surfaces applicable for a given application on the cluster
  • The participants will learn how to audit for security based on best practices using tools and custom scripts

As part of the course delivery, the trainers will share examples of real world security issues found in penetration testing engagements to showcase mapping of the concepts with what usually happens in the real world.

What to bring?

  • At least 8 GB of RAM, 10GB of disk space free on the system
  • Laptop should support hardware-based visualization
    • If your laptop can run a 64-bit virtual machine in Oracle VirtualBox it should work
    • Other visualization software might work but we will not be able to provide support for that
  • Network Connectivity or USB Ports for copying data
  • Trainer will provide the VM and dedicated Kubernetes cluster configuration for each student with administrative access to have a hand-on experience during the training

Prerequisites

  • Basic knowledge of using the Linux command line
  • System administration basics like servers, applications configuration and deployment
  • Familiarity with container environments like Docker would be useful

Who Should Attend?

  • Penetration Testers, Security Engineers and Bug bounty hunters
  • System administrators, DevOps and SecOps Teams
  • Anyone interested in the container infrastructure security

What to expect?

  • Complete hands-on training with a practical approach and real-world scenarios
  • Ebooks of the training covering all hands-on in a step by step guide (HTML, PDF, EPub, Mobi)
  • Git repository of all the custom source code, scripts, playbooks used during the training
  • Resources and references for further learning and practice

What not to expect?

  • A lot of hand holding about basic concepts already mentioned in the things you should be familiar with
  • A lot of theory. This is meant to be a completely hands-on training!!
  • To become an accomplished DevOps or containers expert
