SecretScanner

Deepfence SecretScanner can find unprotected secrets in container images or file systems.

What are Secrets?

Secrets are any kind of sensitive or private data which gives authorized users permission to access critical IT infrastructure (such as accounts, devices, network, cloud based services), applications, storage, databases and other kinds of critical data for an organization. For example, passwords, AWS access IDs, AWS secret access keys, Google OAuth Key etc. are secrets. Secrets should be strictly kept private. However, sometimes attackers can easily access secrets due to flawed security policies or inadvertent mistakes by developers. Sometimes developers use default secrets or leave hard-coded secrets such as passwords, API keys, encryption keys, SSH keys, tokens etc. in container images, especially during rapid development and deployment cycles in CI/CD pipeline. Also, sometimes users store passwords in plain text. Leakage of secrets to unauthorized entities can put your organization and infrastructure at serious security risk.

Deepfence SecretScanner helps users scan their container images or local directories on hosts and outputs a JSON file with details of all the secrets found.

Check out our blog for more details.

When to use SecretScanner

Use SecretScanner if you need a lightweight, efficient method to scan container images and filesystems for possible secrets (keys, tokens, passwords). You can then review these possible 'secrets' to determine if any of them should be removed from production deployments.

Quick Start

For full instructions, refer to the SecretScanner Documentation.

SecretScanner QuickStart

Install docker and run SecretScanner on a container image using the following instructions:

./bootstrap.sh
docker build --rm=true --tag=quay.io/deepfenceio/deepfence_secret_scanner_ce:2.5.0 -f Dockerfile .

docker pull quay.io/deepfenceio/deepfence_secret_scanner_ce:2.5.0

Generate License Key

Run this command to generate a license key. Work/official email id has to be used.

curl https://license.deepfence.io/threatmapper/generate-license?first_name=<FIRST_NAME>&last_name=<LAST_NAME>&email=<EMAIL>&company=<ORGANIZATION_NAME>&resend_email=true

Scan

docker pull node:8.11

docker run -i --rm --name=deepfence-secretscanner \
    -e DEEPFENCE_PRODUCT=<ThreatMapper or ThreatStryker> \
    -e DEEPFENCE_LICENSE=<ThreatMapper or ThreatStryker license key> \
    -v /var/run/docker.sock:/var/run/docker.sock \
    quay.io/deepfenceio/deepfence_secret_scanner_ce:2.5.0 \
    --image-name node:8.11 \
    --output json > node.json

Rules can also be cached to use next run by mounting a seperate path and passing rules-path argument

docker run -i --rm --name=deepfence-yarahunter \
     -e DEEPFENCE_PRODUCT=<ThreatMapper or ThreatStryker> \
     -e DEEPFENCE_LICENSE=<ThreatMapper or ThreatStryker license key> \
     -v /var/run/docker.sock:/var/run/docker.sock \
     -v /tmp/rules:/tmp/rules \
     quay.io/deepfenceio/deepfence_secret_scanner_ce:2.5.0 \
     --image-name node:8.11 \
     --rules-path=/tmp/rules \
     --output json > node.json
