tf-free VS tfsec

Wonder if this will help you https://github.com/gruberdev/tf-free

It is called tf-free, as in, you can create all the resources in it for free, if you have an account on GCP. It may help you comprehend a few of these subjects in a more realistic scenario, and even experiment with it yourself as a sandbox project. Good luck and let me know if you have any questions.

I've created a project where you can create all the free resources available from the major cloud providers in a single command. I used it as a way to learn infrastructure as a code without relying on companies or external training, and without spending fortunes as well. Furthermore, I hope it helps you, as it did for me.

tfsec Owner/Maintainer: Aqua Security (acquired in 2021) Age: First released on GitHub on March 5th, 2019 License: MIT License tfsec project is no longer actively maintained in favor of the Trivy tool. But because many people still use it and it's quite famous, I added tfsec to this comparison. However, I recommend against using it for new projects.

‍Tfsec acts as a Terraform scanning tool. It is a security-focused linter for Terraform that scans code for security flaws, offering an additional layer of security assurance and helping to maintain a strong security posture.

You can give tfsec a try perhaps

Great toolchain, including Infracost or tfsec.

TFSec is an open-source tool for scanning and detecting potential security vulnerabilities in Terraform code in both HCL and JSON.

We use https://github.com/aquasecurity/tfsec we found checkov.io to be quite noisy

Beyond Snyk and Checkov - I have also used https://github.com/aquasecurity/tfsec at a few organizations both for use locally and in CI (PR Review Checks)

Once I completed the main steps of the challenge, I went back to do some security modificaions including enabled DNSSEC, deploying WAF (I ended up removing this as the costs were quite high and instead set up account level throttling for my API) and running IAM Access Analyser to flag anything I'd over permissioned. I also set up Git commit signing and added a new Git Action workflow to run Tfsec any time I updated my terraform config files
