Attesting Snyk scans

In this tutorial, we will run Snyk scans against the Kosli CLI git repo and attest the results to a Kosli trail. By the end, you will have a Kosli trail with attested Snyk scan results that you can view in the Kosli app.

Prerequisites

To follow the steps in this tutorial, you need to:

Setup Snyk on your machine.
Install Helm if you want to try Snyk IaC attestations, otherwise skip.
Install Docker if you want to try Snyk container attestations, otherwise skip.
Install Kosli CLI.
Get a Kosli API token.

Setup

Set the KOSLI_ORG environment variable to your personal org name and KOSLI_API_TOKEN to your token:

export KOSLI_ORG=<your-personal-kosli-org-name>
export KOSLI_API_TOKEN=<your-api-token>

Clone the Kosli CLI git repo:

git clone https://github.com/kosli-dev/cli.git
cd cli

Create a Flow and Trail

We will start by creating a flow in Kosli to contain trails and artifacts for this tutorial:

kosli create flow snyk-demo --use-empty-template

You should see: flow snyk-demo was created. Then start a trail to bind our Snyk attestations to:

kosli begin trail test-1 --flow snyk-demo

You should see: trail 'test-1' was begun.

Attest Snyk scans

We can now run Snyk scans and attest them to the trail. After each attestation, you can verify the result by navigating to https://app.kosli.com/`your-personal-org-name`/flows/snyk-demo/trails/test-1 in the Kosli app.

Open Source scan

Snyk Open Source finds vulnerabilities in the open-source libraries used by your application:

snyk test --sarif-file-output=os.json

kosli attest snyk --flow snyk-demo --trail test-1 --name open-source-scan --scan-results os.json --commit HEAD

You should see: snyk attestation 'open-source-scan' is reported to trail: test-1.

Code scan

Snyk Code scans your source code for security issues:

snyk code test --sarif-file-output=code.json

kosli attest snyk --flow snyk-demo --trail test-1 --name code-scan --scan-results code.json --commit HEAD

You should see: snyk attestation 'code-scan' is reported to trail: test-1.

Container scan

Snyk Container scans container images for security issues:

docker pull ghcr.io/kosli-dev/cli:v2.8.3
snyk container test ghcr.io/kosli-dev/cli:v2.8.3 --file=Dockerfile --sarif-file-output=container.json

kosli attest snyk --flow snyk-demo --trail test-1 --name container-scan --scan-results container.json --commit HEAD

You should see: snyk attestation 'container-scan' is reported to trail: test-1.

IaC scan

Snyk IaC scans IaC configuration files (Terraform, Kubernetes, Helm) for security issues:

helm template ./charts/k8s-reporter --output-dir helm \
  --set kosliApiToken.secretName=secret \
  --set reporterConfig.kosliEnvironmentName=foo \
  --set reporterConfig.kosliOrg=bar

snyk iac test helm --sarif-file-output=helm.json

kosli attest snyk --flow snyk-demo --trail test-1 --name helm-scan --scan-results helm.json --commit HEAD

You should see: snyk attestation 'helm-scan' is reported to trail: test-1.

What you’ve accomplished

You have run four types of Snyk scans and attested each result to a Kosli trail. The trail now holds a tamper-proof record of your scan findings, linked to a specific git commit. From here you can:
