FIPS 140-3 Certification

This image is FIPS-validated to ensure its cryptographic operations meet the Federal Information Processing Standards (FIPS) required for secure government and regulated environments. Its core cryptographic modules are validated under the NIST Cryptographic Module Validation Program (CMVP) and comply with the FIPS 140-3 standard.

To verify that the FIPS 140-3 provider is configured and active, follow the instructions in the FIPS compliance tab.

Try It Out

To test the Minimus OpenSCAP-FIPS image, follow the steps below to scan a container using its file system.

Download the Minimus STIG file ssg-minimus-gpos-ds.xml (Link).

wget -O ssg-minimus-gpos-ds.xml \
https://raw.githubusercontent.com/minimusio/examples/main/STIG/ssg-minimus-gpos-ds.xml

mkdir -p "$(pwd)/openscap_results"

Change the directory ownership to match the container's UID to grant the OpenSCAP container write access:

sudo chown 1000:1000 "$(pwd)/openscap_results"

Pull the image you plan to scan. For example, if we want to scan nginx:

docker pull reg.mini.dev/nginx:latest

Update the placeholder {IMAGE_TO_SCAN} in the command below before running the scan:

docker run --user root \
  -v "$PWD/ssg-minimus-gpos-ds.xml:/ssg-minimus-gpos-ds.xml:ro" \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v "$PWD/openscap_results:/output" \
  --entrypoint "" \
  reg.mini.dev/openscap-fips \
  /usr/bin/oscap-docker image {IMAGE_TO_SCAN} -- \
    xccdf eval \
    --profile "xccdf_basic_profile_.check" \
    --results /output/scan-results.xml \
    --report  /output/report.html \
    /ssg-minimus-gpos-ds.xml

For example, for the Minimus nginx image, the command would look like this:

docker run --user root \
  -v "$PWD/ssg-minimus-gpos-ds.xml:/ssg-minimus-gpos-ds.xml:ro" \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v "$PWD/openscap_results:/output" \
  --entrypoint "" \
  reg.mini.dev/openscap-fips \
  /usr/bin/oscap-docker image reg.mini.dev/nginx:latest -- \
    xccdf eval \
    --profile "xccdf_basic_profile_.check" \
    --results /output/scan-results.xml \
    --report  /output/report.html \
    /ssg-minimus-gpos-ds.xml

The STIG report will print directly to the terminal. Once the scan completes, open the openscap_results folder to view the results. You should see two files:

• scan-results.xml will include the raw scan output and is machine-readable.

• report.html is a human-readable HTML report.

You can convert the DISA STIG report to other formats including JSON, CSV, HTML, DISA Checklist, etc. using the MITRE Heimdall tool. Learn more

Technical Considerations

The OpenSCAP-FIPS image provided by Minimus has no alternative in Docker Hub. It can be used as a minimal alternative for installing OpenSCAP locally.
