StackJanitor VS cfn_nag

🧹 StackJanitor is an event-driven serverless application that cleans up AWS CloudFormation Stacks in development environments based on TTL (expiration time) and git pull request events.

.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.
