  • 2 Learning Objectives

About this Hands-on Lab

Runtime threat detection can be an important component of a secure Kubernetes environment. Falco is a powerful tool in detecting anomalous activity as it occurs. In this lab, you will practice your skills with behavioral analysis in Kubernetes by checking for threats in a real cluster using Falco.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a Falco Rules File Configured to Scan the Container

The container in question is running inside a Pod called nginx in the default namespace. The container is also called nginx. For this exercise, you can assume that the container name is unique in the cluster.

Create a Falco rules file at /home/cloud_user/nginx-rules.yml with a rule to report any newly-spawned processes in this container.

The rule’s output should include the following:

  • timestamp
  • process name
  • UID
  • container ID
  • container name
  • container image name
Run Falco to Obtain a Report of the Activity and Save It to a File

Falco is already installed on the worker node. Using your rules file, run Falco for 45 seconds or so to obtain a report of the container’s activity.

Save the report to /home/cloud_user/falco-report.log.

Additional Resources

Your company, SecuriCorp, is using Kubernetes to run some application, including a web server.

You've gotten a call from one of your team members indicating that they have seen some suspicious activity occurring in a container. Use Falco to analyze the container for any spawning processes.

You can use the official Falco documentation as a lab reference.
