tfsec VS checkov

Using pre-commit framework with terraform repository, will help your code to be kept clean, formated, updated document and checked for tf security issues (optional with tfsec) before committing and pushing the code to git source.

Here again more than one tool exists to assist. We will highlight two of the most popular ones here: tfsec and checkov. Both provide a predefined set of checks that they use to inspect your code, allowing to explicitly open exceptions (if you really want to) by annotating your code with comments, and adjust the configuration to ignore some modules, for example.

An additional benefit of using a CI workflow is adding automated tests. In this scenario, I’ve added a step leveraging tfsec to scan for static code vulnerabilities. In the example below, tfsec warns against creating an Azure network security rule which is fully open. This will halt and fail the workflow unless I provide an ignore comment to accept the warning.

· Provision an EKS Cluster (AWS) · Terraform v15.0 · Terraform Registry · Pre-Commit · Terraform Pre-commit · Terraform-docs · Tflint · Tfsec

Using terraform, create a skeleton directory that they can review for how EC2 instances should be created. Use tools like https://github.com/tfsec/tfsec or other scanners/linters to validate that your developers followed this process and didn't uncheck something.

I know tfsec (https://github.com/tfsec/tfsec) which is pretty good for AWS resources but I think vSphere resources are not implemented.

tfsec/tfsec (Go): 🔒🌍 Static analysis powered security scanner for your terraform code

Checkov Owner/Maintainer: Prisma Cloud by Palo Alto Networks (acquired in 2021) Age: First released on GitHub on March 31st, 2021 License: Apache License 2.0

‍Checkov is another great tool that examines your Terraform files (.tf), parsing the configurations and evaluating them against a comprehensive set of predefined policies. It scans Terraform-managed infrastructure and detects misconfigurations that could lead to security issues or non-compliance with best practices and regulations.

Bridgecrew — Infrastructure as code (IaC) security powered by the open source tool - Checkov. The core Bridgecrew platform is free for up to 50 IaC resources.

Kustomize: It provides a solution to customize the Kubernetes resource base configuration and differential configuration without template and DSL. It does not solve the constraint problem itself, but needs to cooperate with a large number of additional tools to check constraints, such as Kube-linter, Checkov and kubescape.

Checkov is a versatile static code analysis tool designed for infrastructure as code (IaC) and software composition analysis (SCA). It supports a wide range of technologies, including Terraform, CloudFormation, Kubernetes, Docker, and others, to detect security and compliance issues through graph-based scanning. Checkov also performs SCA scans, identifying vulnerabilities in open source packages and images by checking for Common Vulnerabilities and Exposures (CVEs). Additionally, it is integrated into Prisma Cloud Application Security, a platform that helps developers secure cloud resources and infrastructure-as-code files, enabling the identification, rectification, and prevention of misconfigurations throughout the development lifecycle.

For your Dockerfiles, you can also scan them. There are lots of tools that can check your Dockerfiles. They will validate if Dockerfile is compliant with Docker best practices such as not using root user, making sure a health check exists, and not exposing the SSH port. You can use Snyk and Checkov.

We use https://www.checkov.io/ for this, it's very simple to get started with and works really well as PR quality gate

Once there is a CI pipeline for delivering infra changes you can add static code analysis tools (checkov) and even start testing changes (terratest)

I just had a brief chat with one of the developers of Checkov and it sounds nice (and open source). I haven't had a chance to play with it, but if you want to it's at https://www.checkov.io/
