Windows Container Image Scanning [BETA]

    This doc applies only to the Legacy Scanning engine. Make sure you are using the correct documentation: Which Scanning Engine to Use


    Sysdig provides a standalone vulnerability scanning and policy engine for Windows containers called the Scanning Inspector. It can be used on both Windows and Linux hosts.

    This is a standalone scanning engine. There is no centralized UI, management, or historical data. These features are planned for a future release.


    • Identify Windows container image vulnerabilities from:

      • Windows OS CVEs
    • Windows or Linux hosts

    • Reports in JSON and PDF

    • Policy support

      • Severity

      • Fix available

      • Days since fixed

    Ways to Use

    The Windows Scanning Inspector can be integrated into the CI/CD pipeline or deployed ad hoc during development.

    CI/CD Pipeline

    The image below shows how the Scanning Inspector fits within a development pipeline. A policy can pass or fail the workflow and provide a PDF or JSON report for each CI/CD job.

    Ad Hoc Scanning

    Developers can run the Windows Scanning Inspector anywhere Docker can be run: a machine (Mac, Windows, or Linux), VM, or Cloud. It provides immediate feedback on Windows OS or .NET vulnerabilities, allowing quick mitigation of known security vulnerabilities.



    Request a Quay secret from your Sysdig sales agent.

    Install Scanning Inspector

    1. Use the provided secret to authenticate with Quay:

      PULL_SECRET="enter secret"
      AUTH=$(echo $PULL_SECRET | base64 --decode | jq -r '.auths."".auth'| base64 --decode)
      docker login -u "$QUAY_USERNAME" -p "$QUAY_PASSWORD"
    2. Pull the Scanning Inspector component for Windows or Linux:

      • Window Host/Kernel:

      • Linux Host/Kernel:

    3. Run the --help command to see the parameters available for the Scanning Inspector.

      docker run --rm -v $(pwd):/outdir --help

    Parameters for Scanning Inspector

    The --help command lists the available parameters and their usage. They can be divided into those related to scanning for vulnerabilities and generating a report, and those related to creating policies.

    Use Cases

    Scan Remote Image and Save PDF Report

    In this example, the Inspector should scan a remote image on a Linux host and save the resulting report as a PDF to ./scanResults.pdf

    docker run --rm -v $(pwd):/outdir \
      -t pull \ # pull image from remote repo
      -i \ # inspect container name
      -f pdf \ # format
      -o /outdir/scanResults.pdf # output name

    Scan Local Image Apply Policy Conditions and Generate JSON Report

    In this example, the Inspector should:

    • Scan a local image on a Windows host

    • Mount the Docker socket to access the local image. This can be done with -v "//./pipe/docker_engine://./pipe/docker_engine" in Windows

    • Apply a policy to specify vulnerabilities with a minimum severity of high and a minimum number of days after the vulnerability fix is available set to 7.

    • If the scan does not pass, the container will have an exit 1 error.

    • The report is in JSON

    docker run --rm -v $(pwd):/outdir -v "//./pipe/docker_engine://./pipe/docker_engine" \
      -t daemon \ # Use local daemon for image scan
      -i nanoserver:10.0.17763.1518 # local image name
      -min_severity high # Any sev high or greater CVEs will fail the image scan policy
      -min_days_fix 7 # Only fail scan if found vulnerabilities have a fix for more than 7 days
      -f json \ # format
      -o /outdir/scanResults.json # output name
