docker-bench-security VS cfn_nag

Scanning your container images for vulnerabilities is a good approach. But this scanning is not one time job, it should be done regularly (weekly, monthly, etc.) You need to follow vulnerability reports and fix all of the vulnerabilities as soon as possible. I recommend some open-source tools that could be useful: Trivy, Docker-Bench, Grype.

For Docker configuration I have used this in the past (it utilizes the CIS Docker Benchmark): https://github.com/docker/docker-bench-security

So the main tool to scan against the CIS Docker benchmark (I'm presuming that's the one you're interested in) is https://github.com/docker/docker-bench-security .

git clone https://github.com/docker/docker-bench-security.git cd docker-bench-security sudo sh docker-bench-security.sh

when deploying images on cloud, I always run it thru "docker bench security" It helps finding potential security holes in my images.

Use Docker Bench for Security to audit your container images

Other tools you can use are linux-bench, docker-bench, kube-bench, kube-hunter, kube-striker, Cloud Custodian, OVAL, and OS Query.

I run https://github.com/docker/docker-bench-security against my environment. I would determine what was non-applicable/not scored and then start with scored. Then I would do not scored. My team had made their own Dockerfiles when I started and just grabbed whatever image/version and getting things baselined was not fun. I had to do this for docker-compose and stay on version 2 yml as otherwise I had to go to swarm.

.pre-commit-config.yaml – contains the cfn-lint and cfn_nag pre-commit hooks.

For generic CloudFormation templates, check CFN-NAG.

If you use CDK, you should implement CDK nag; otherwise, use cfn-nag.

cfn_nag

CodeBuild will run a linting check against the CloudFormation Template using cfn-lint and will then run cfn-nag to check for patterns that indicate insecure resources within the CloudFormation template.

Security checks for the Cloudformation stack using cfn-nag

cdk-nag contains several Aspects to check your applications for best practices. It is especially useful if you need to be HIPAA-compliant or have other compliance requirements. It is inspired by cfn_nag which is a a tool checking for patterns in your CloudFormation templates.

cfn-lint and cfn_nag or other tools of that nature to check as you write so you don't need to continually try to deploy only to find that you've done something dumb.

There is another tool called cfn_nag that can check your code for potentially any insecure infrastructure. When you read the documentation around this tool, the author says it can check for things such as:

I recently wanted to use the cfn-nag tool on some templates I was writing but couldn't find any instructions to install on Windows, but I have found a way to do it.
