AWS Config Terraform Module

Dependencies

• Account Setup module

Resource List

• AWS Config Recorder
• AWS Config Delivery Channel (S3 + SNS)
• AWS IAM policies
• AWS Config Aggregator (Account or Organization)
• Uploads S3 Object(s) to X bucket for the Config Conformance Packs
• Config Conformance Packs x2: Operational-Best-Practices-for-FedRAMP and Operational-Best-Practices-for-NIST-800-53-rev-5 Modified from source Github

Code Updates

• Please be sure to update AWS Config Rules yaml files from here
• Due to the nature of this Github repository being opensource there are a few rules out of the box that were removed in order to get this module to properly scan the AWS Accounts

Deployment Steps

This module can be called as outlined below.

• Change directories to the config directory.
• From the terraform/aws/config directory run terraform init.
• Run terraform plan to review the resources being created.
• If everything looks correct in the plan output, run terraform apply.

Usage

Include example for how to call the module below with generic variables

module "config" {
  source = "github.com/Coalfire-CF/terraform-aws-config"

  resource_prefix        = var.resource_prefix
  s3_config_arn          = data.terraform_remote_state.mgmt_account_setup.outputs.s3_config_arn
  s3_config_id           = data.terraform_remote_state.mgmt_account_setup.outputs.s3_config_id
  config_kms_key_arn     = data.terraform_remote_state.mgmt_account_setup.outputs.config_kms_key_arn
  s3_kms_key_arn         = data.terraform_remote_state.mgmt_account_setup.outputs.s3_kms_key_arn
  sns_kms_key_id         = data.terraform_remote_state.mgmt_account_setup.outputs.sns_kms_key_id
  conformance_pack_names = ["Operational-Best-Practices-for-FedRAMP", "Operational-Best-Practices-for-NIST-800-53-rev-5"]
  delivery_frequency     = "TwentyFour_Hours"

  ## Aggregator 
  aws_regions      = var.aws_regions
  account_ids      = local.share_accounts
  aggregation_type = "organization"
}
