Disallowed SSH Connection
Event Information
Meaning
- Indicates that an SSH connection attempt was made to a Kubernetes pod, which is a security risk as it bypasses the intended container orchestration mechanisms.
- It could suggest a potential security breach or unauthorized access attempt within the cluster.
- Immediate investigation and remediation are necessary to ensure compliance with security best practices and prevent further unauthorized access.
To investigate further:
-
Check the specific pod and node where the SSH connection attempt was made:
kubectl get pods --all-namespaces
kubectl describe pod <pod_name> -n <namespace>
-
Review the pod’s security context and network policies to identify any misconfigurations:
kubectl get pod <pod_name> -n <namespace> -o yaml
-
Monitor network traffic and access logs within the cluster to detect any other suspicious activities:
kubectl logs <network_policy_controller_pod> -n kube-system
Remediation
- Create a Kubernetes Pod manifest file with a Python container that includes the necessary logic to remediate the Disallowed SSH Connection event.
- Use the Kubernetes Python client library to interact with the Kubernetes API and deploy the remediation Pod.
- Apply the Pod manifest using kubectl apply -f remediation_pod.yaml to remediate the event.
