Assessment Title

Rule Text

Kubernetes Controller Manager must disable profiling.

Description

Discussion Text

Kubernetes profiling provides the ability to analyze and troubleshoot Controller Manager events over a web interface on a host port. Enabling this service can expose details about the Kubernetes architecture. This service must not be enabled unless deemed necessary.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Change to the /etc/kubernetes/manifests/ directory on the Kubernetes Control Plane. Run the command:
grep -i profiling * 

If the setting "profiling" is not configured in the Kubernetes Controller Manager manifest file or it is set to "True", this is a finding.

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

#!/bin/sh
# OVAL definition: oval:mil.disa.stig.kubernetes:def:242409
if [ ! -f "/etc/kubernetes/manifests/kube-controller-manager.yaml" ]; then echo "PASS"; exit 0; fi; grep -qE "(?i)^[ -]*profiling=(\w+)" /etc/kubernetes/manifests/kube-controller-manager.yaml || echo "PASS"; exit 0; if grep -qE "(?i)^[ -]*profiling=true" /etc/kubernetes/manifests/kube-controller-manager.yaml; then echo "FAIL"; exit 1; fi; echo "PASS"; exit 0

Remediation

Edit the Kubernetes Controller Manager manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Control Plane. Set the argument "--profiling value" to "false".
