TerraGoat - Vulnerable Terraform Infrastructure

TerraGoat is Bridgecrew's "Vulnerable by Design" Terraform repository.

TerraGoat is Bridgecrew's "Vulnerable by Design" Terraform repository. TerraGoat is a learning and training project that demonstrates how common configuration errors can find their way into production cloud environments.

Introduction

This repo is a clone of [TerraGoat][https://github.com/bridgecrewio/terragoat]

TerraGoat was built to enable DevSecOps design and implement a sustainable misconfiguration prevention strategy. It can be used to test a policy-as-code framework like Checkov, inline-linters, pre-commit hooks or other code scanning methods.

TerraGoat follows the tradition of existing *Goat projects that provide a baseline training ground to practice implementing secure development best practices for cloud infrastructure.

Important notes

• Where to get help: the Bridgecrew Community Slack

Before you proceed please take a not of these warning:

⚠️ TerraGoat creates intentionally vulnerable AWS resources into your account. DO NOT deploy TerraGoat in a production environment or alongside any sensitive AWS resources.

Requirements

• Terraform 0.12
• aws cli

To prevent vulnerable infrastructure from arriving to production see: checkov, the open source static analysis tool for infrastructure as code.

Getting started

Installation

You can deploy multiple TerraGoat stacks in a single AWS account using the parameters TF_VAR_environment and TF_VAR_environment.

Create an S3 bucket backend to keep Terraform state

export TERRAGOAT_STATE_BUCKET="mydevsecops-bucket"
export TF_VAR_company_name=acme
export TF_VAR_environment=mydevsecops
export TF_VAR_region="us-east-1"

aws s3api create-bucket --bucket $TERRAGOAT_STATE_BUCKET \
    --region $TF_VAR_region --create-bucket-configuration LocationConstraint=$TF_VAR_region

# Enable versioning
aws s3api put-bucket-versioning --bucket $TERRAGOAT_STATE_BUCKET --versioning-configuration Status=Enabled

# Enable encryption
aws s3api put-bucket-encryption --bucket $TERRAGOAT_STATE_BUCKET --server-side-encryption-configuration '{
  "Rules": [
    {
      "ApplyServerSideEncryptionByDefault": {
        "SSEAlgorithm": "aws:kms"
      }
    }
  ]
}'

Apply TerraGoat

cd terraform/
terraform init \
-backend-config="bucket=$TERRAGOAT_STATE_BUCKET" \
-backend-config="key=$TF_VAR_company_name-$TF_VAR_environment.tfstate" \
-backend-config="region=$TF_VAR_region"

terraform apply

Remove TerraGoat

terraform destroy

Creating multiple TerraGoat stacks

cd terraform/
export TERRAGOAT_ENV=$TF_VAR_environment
export TERRAGOAT_STACKS_NUM=5
for i in $(seq 1 $TERRAGOAT_STACKS_NUM)
do
    export TF_VAR_environment=$TERRAGOAT_ENV$i
    terraform init \
    -backend-config="bucket=$TERRAGOAT_STATE_BUCKET" \
    -backend-config="key=$TF_VAR_company_name-$TF_VAR_environment.tfstate" \
    -backend-config="region=$TF_VAR_region"

    terraform apply -auto-approve
done

Deleting multiple TerraGoat stacks

cd terraform/
export TF_VAR_environment = $TERRAGOAT_ENV
for i in $(seq 1 $TERRAGOAT_STACKS_NUM)
do
    export TF_VAR_environment=$TERRAGOAT_ENV$i
    terraform init \
    -backend-config="bucket=$TERRAGOAT_STATE_BUCKET" \
    -backend-config="key=$TF_VAR_company_name-$TF_VAR_environment.tfstate" \
    -backend-config="region=$TF_VAR_region"

    terraform destroy -auto-approve
done

Bridgecrew's IaC heard of goats:

• CfnGoat - Vulnerable by design Cloudformation template
• TerraGoat - Vulnerable by design Terraform stack

Contributing

Contribution is welcomed!

We would love to hear about more ideas on how to find vulnerable infrastructure-as-code design patterns.

Support

Bridgecrew builds and maintains TerraGoat to encourage the adoption of policy-as-code.
