Securing an AWS account can seem like a daunting task, but with the help of the Terraform AWS Secure Baseline module, the process becomes manageable and streamlined. This module helps you configure your AWS account to adhere to security best practices, based on well-established benchmarks. In this guide, we will walk you through the steps of setting up this secure baseline, while also providing troubleshooting tips, should you encounter any issues.

Features of the Terraform AWS Secure Baseline

The module encompasses various areas for maintaining security:

• Identity and Access Management: Set IAM policies, create support roles, and enable auditing features.
• Logging and Monitoring: Enable CloudTrail, CloudWatch, and Security Hub to monitor account activities and maintain logs.
• Networking and Computing: Configure your VPC settings, including flow logs and security groups, to secure network traffic.

Getting Started with Terraform AWS Secure Baseline

Here’s a simple breakdown of how to deploy this module:

data "aws_caller_identity" "current" {}
data "aws_region" "current" {}

module "secure_baseline" {
  source                          = "nozaq/secure-baseline/aws"
  audit_log_bucket_name           = "YOUR_BUCKET_NAME"
  aws_account_id                  = data.aws_caller_identity.current.account_id
  region                          = data.aws_region.current.name
  support_iam_role_principal_arns = [YOUR_IAM_USER]

  providers = {
    aws               = aws
    aws.ap-northeast-1 = aws.ap-northeast-1
    aws.us-east-1      = aws.us-east-1
    # Add additional regions as needed
  }
}

Think of the above code as a recipe. Each ingredient is essential to create a secure environment:

The data blocks are like gathering your resources—knowing who you are (AWS account ID) and what area you’re working in (region). The module block is where you put it all together—like combining those ingredients in a pot to cook your dish (your AWS Secure Baseline setup).

Using the Module

Deployment is not only about setting it up once but ensuring ongoing security. The module provides features for managing multiple accounts in an AWS Organization, enabling you to have a centralized approach to security across multiple environments.

Each submodule can be used independently as needed. You can manage alarms, IAM roles, CloudTrail, and more according to your security strategy.

Troubleshooting Tips

While setting up the Terraform AWS Secure Baseline module, you may encounter some hiccups. Here are a few troubleshooting steps you can follow:

• Check Permissions: Ensure that your IAM user has the necessary permissions to execute Terraform actions.
• Validate Configuration: Run `terraform validate` to catch any syntax errors or misconfigurations.
• Region Mismatch: Double-check if your desired AWS region is correctly referenced in your provider configurations.
