Ensure that the azure.json file ownership is set to root:root

MediumLevel 1Automatedaks

Description

The azure.json file on an AKS worker node contains Azure cloud-provider configuration used by Kubernetes components to interact with Azure resources such as load balancers, storage, and networking. Ensure that the file ownership is set to root:root. Runs on each AKS node; SKIPs where /etc/kubernetes/azure.json is absent.

How it is checked

Audit method: Shell command

shell

set -f
f=""; for x in /etc/kubernetes/azure.json; do if [ -e "$x" ]; then f=$x; break; fi; done
[ -n "$f" ] || exit 1
o=$(stat -Lc %U:%G "$f") || exit 1
if [ "$o" = "root:root" ]; then echo compliant; else echo "noncompliant: $f $o"; fi

Expected output: compliant

How it is fixed

Fix method: Shell command

shell

chown root:root /etc/kubernetes/azure.json
