Event Information

​
Meaning

  • The System procs network activity event in a Kubernetes cluster indicates that there is suspicious network activity happening within the system processes.
  • It could be a sign of a potential security breach or unauthorized network communication.
  • This event should be investigated further to identify the source of the network activity and take appropriate actions to mitigate any potential risks.

​
Remediation

  1. Create a Kubernetes Deployment manifest file to deploy a Python script as a container:
apiVersion: apps/v1
kind: Deployment
metadata:
  name: remediation-script
spec:
  replicas: 1
  selector:
    matchLabels:
      app: remediation-script
  template:
    metadata:
      labels:
        app: remediation-script
    spec:
      containers:
      - name: remediation-script
        image: python:3
        command: ["python", "-u"]
        args: ["remediation_script.py"]
        volumeMounts:
        - name: shared-data
          mountPath: /data
      volumes:
      - name: shared-data
        emptyDir: {}
  1. Create a Kubernetes Service manifest file to expose the deployment:
apiVersion: v1
kind: Service
metadata:
  name: remediation-script-service
spec:
  selector:
    app: remediation-script
  ports:
  - protocol: TCP
    port: 80
    targetPort: 80
  1. Create a Python script named remediation_script.py that performs the necessary remediation actions:
# Add your remediation logic here

To remediate the event, you can follow these steps:

  • Apply the Deployment manifest file using the kubectl apply -f deployment.yaml command.

  • Apply the Service manifest file using the kubectl apply -f service.yaml command.

  • Update the remediation_script.py file with the necessary remediation logic.

  • Access the remediation script by using the Service’s ClusterIP or NodePort, depending on your network setup.

  • Monitor the logs of the remediation script container to ensure it is running and performing the desired actions.
