Event Information

​
Meaning

  • Indicates that a Kubernetes client tool was launched inside a container within the cluster, which could potentially be a security concern.
  • It is important to investigate the source and purpose of this tool to ensure it complies with security policies and standards.
  • To further analyze this event, you can use kubectl to inspect the pod where the tool was launched: 
    kubectl describe pod <pod_name>

​
Remediation

  • Create a Kubernetes Pod manifest file with a Python container that includes the necessary Python Kubernetes API library.
  • Use a Kubernetes ServiceAccount with appropriate RBAC permissions to interact with the Kubernetes API.
  • Write a Python script that uses the Kubernetes API to list and delete the offending Pod(s) based on the event criteria.
