Performing Docker Bench Security Assessment

Overview

Docker Bench for Security is an open-source script that checks dozens of common best practices around deploying Docker containers in production. Based on the CIS Docker Benchmark, it audits host configuration, Docker daemon settings, container images, runtime configurations, and security operations to generate a compliance report with pass/fail/warn results.

When to Use

• When conducting security assessments that involve performing docker bench security assessment
• When following incident response procedures for related security events
• When performing scheduled security testing or auditing activities
• When validating security controls through hands-on testing

Prerequisites

• Docker Engine installed and running
• Root or sudo access on Docker host
• Docker Bench Security script or container image

Workflow

Step 1: Run Docker Bench Security

# Run as a container (recommended)
docker run --rm --net host --pid host --userns host --cap-add audit_control \
  -e DOCKER_CONTENT_TRUST=$DOCKER_CONTENT_TRUST \
  -v /etc:/etc:ro \
  -v /usr/bin/containerd:/usr/bin/containerd:ro \
  -v /usr/bin/runc:/usr/bin/runc:ro \
  -v /usr/lib/systemd:/usr/lib/systemd:ro \
  -v /var/lib:/var/lib:ro \
  -v /var/run/docker.sock:/var/run/docker.sock:ro \
  --label docker_bench_security \
  docker/docker-bench-security

# Run with JSON output
docker run --rm --net host --pid host --userns host --cap-add audit_control \
  -v /etc:/etc:ro \
  -v /var/lib:/var/lib:ro \
  -v /var/run/docker.sock:/var/run/docker.sock:ro \
  docker/docker-bench-security -l /dev/stdout 2>/dev/null | tee docker-bench-results.json

# Run specific sections only
docker run --rm --net host --pid host --userns host \
  -v /var/run/docker.sock:/var/run/docker.sock:ro \
  docker/docker-bench-security -c container_images,container_runtime

Step 2: Interpret Results

[INFO] 1 - Host Configuration
[PASS] 1.1.1 - Ensure a separate partition for containers has been created
[WARN] 1.1.2 - Ensure only trusted users are allowed to control Docker daemon
[PASS] 1.1.3 - Ensure auditing is configured for the Docker daemon

[INFO] 2 - Docker daemon configuration
[FAIL] 2.1 - Run the Docker daemon as a non-root user
[PASS] 2.2 - Ensure network traffic is restricted between containers on the default bridge

Step 3: Remediate Common Failures
