Using a version manager like tfenv makes it easier to manage multiple Terraform versions locally, allowing for quick switching between projects and ensuring the development environment is as close to production as possible. Explicitly setting required Terraform versions helps prevent issues caused by running the wrong version on specific machines, providing a clean error when trying to run an `apply` command with the incorrect environment. Setting module versions makes it easier to control changes to infrastructure components and enables progressive rollouts of module upgrades. Preventing local `apply` commands and encouraging a pull-request review process helps maintain a safer workflow, while securing Terraform code using tools like Snyk IaC can detect misconfigurations and provide guided fixes to prevent damage from breaches. Additionally, automating IaC security and compliance in workflows with Snyk can help protect infrastructure from the source.
