During a recent OWASP Netherlands meetup security scanners were discussed to prevent mistakes and also Checkmarx presented their tool KICS for scanning for security vulnerabilities and configuration errors in Infrastructure-as-Code. Development of KICS goes fast since late 2020 and can catch some common mistakes with known Infrastructure-as-Code definitions like Terraform, Cloudformation, and Ansible for example.
KICS can be used as a standalone scanner as it is written in Go and with GitHub Actions. For now, let’s test it with a Terraform configuration in a GitHub Workflow to see how it works and how useful it is. Maybe in the future, we will test it with Ansible and Docker as well.

Terraform keeps a cache of state files in the
.terraform directory stored in Terraform Cloud so that it can be accessed by everyone in the organization. For existing resources Terraform has to import the state for a defined resource otherwise it will fail. Sometimes the state is invalid or an API will return an unexpected code and Terraform will fail to proceed.
The example below passed the error from the Cloudflare API via Terraform Cloud to the user but does not indicate the error. After verifying the state manually some resource records were already removed from the zone and triggered an
81044 error. But the state was not removed and Terraform Cloud could not find the resource record to remove from the state database.

HashiCorp Vagrant normally selects the right hypervisor, but the version shipped with Fedora 30 prefers to run within the QEMU user session of the hypervisor. A .Vagrantfile it would match the default behavior which doesn’t require any system privileges is shown below.
In some cases a virtual machine needs to run on QEMU system level and that can be done by changing the domain.uri from “qemu:///session” to “qemu:///system”. Vagrant now creates the virtual machine at the system level of the hypervisor and isn’t depending on any user environment to run.
