IaC security best practices

Ensuring security within IaC is paramount as it directly affects the provisioning and configuration of resources. Here are some detailed IaC security best practices and examples:

• Use secret management systems

  Do not hardcode secrets or sensitive information in your IaC scripts. Instead of embedding API keys or database passwords in your Terraform script, use tools such as AWS Secrets Manager, HashiCorp Vault, or Azure Key Vault to fetch them at runtime.
