Description

Pods should not run containers with the NET_RAW capability. NET_RAW capability is present by default, but is unnecessary in most applications. An attacker could leverage NET_RAW to spy on network traffic or to generate IP traffic with spoofed addresses.

How to fix?

Set the drop attribute to ALL/NET_RAW in spec.containers.securityContext.capabilities.

Example Configuration


apiVersion: v1
kind: Pod
metadata:
  name: valid
spec:
  containers:
  - name: hello
    image: gcr.io/google-samples/node-hello:1.0
    securityContext:
      capabilities:
        drop: ["NET_RAW"]
