Component: `security-hub`

This component is responsible for configuring Security Hub within an AWS Organization.

Amazon Security Hub enables users to centrally manage and monitor the security and compliance of their AWS accounts and resources. It aggregates, organizes, and prioritizes security findings from various AWS services, third-party tools, and integrated partner solutions.

Here are the key features and capabilities of Amazon Security Hub:

Centralized security management: Security Hub provides a centralized dashboard where users can view and manage security findings from multiple AWS accounts and regions. This allows for a unified view of the security posture across the entire AWS environment.
Automated security checks: Security Hub automatically performs continuous security checks on AWS resources, configurations, and security best practices. It leverages industry standards and compliance frameworks, such as AWS CIS Foundations Benchmark, to identify potential security issues.
Integrated partner solutions: Security Hub integrates with a wide range of AWS native services, as well as third-party security products and solutions. This integration enables the ingestion and analysis of security findings from diverse sources, offering a comprehensive security view.
Security standards and compliance: Security Hub provides compliance checks against industry standards and regulatory frameworks, such as PCI DSS, HIPAA, and GDPR. It identifies non-compliant resources and provides guidance on remediation actions to ensure adherence to security best practices.
Prioritized security findings: Security Hub analyzes and prioritizes security findings based on severity, enabling users to focus on the most critical issues. It assigns severity levels and generates a consolidated view of security alerts, allowing for efficient threat response and remediation.
Custom insights and event aggregation: Security Hub supports custom insights, allowing users to create their own rules and filters to focus on specific security criteria or requirements. It also provides event aggregation and correlation capabilities to identify related security findings and potential attack patterns.
Integration with other AWS services: Security Hub seamlessly integrates with other AWS services, such as AWS CloudTrail, Amazon GuardDuty, AWS Config, and AWS IAM Access Analyzer. This integration allows for enhanced visibility, automated remediation, and streamlined security operations.
Alert notifications and automation: Security Hub supports alert notifications through Amazon SNS, enabling users to receive real-time notifications of security findings. It also facilitates automation and response through integration with AWS Lambda, allowing for automated remediation actions.

By utilizing Amazon Security Hub, organizations can improve their security posture, gain insights into security risks, and effectively manage security compliance across their AWS accounts and resources.

Deployment Overview

This component is complex in that it must be deployed multiple times with different variables set to configure the AWS Organization successfully.

It is further complicated by the fact that you must deploy each of the component instances described below to every region that existed before March 2019 and to any regions that have been opted-in as described in the AWS Documentation.

In the examples below, we assume that the AWS Organization Management account is root and the AWS Organization Delegated Administrator account is security, both in the core tenant.

Deploy to Delegated Administrator Account

First, the component is deployed to the Delegated Administrator account in each region to configure the Security Hub instance to which each account will send its findings.

# core-ue1-security
components:
  terraform:
    security-hub/delegated-administrator/ue1:
      metadata:
        component: security-hub
      vars:
        enabled: true
        delegated_administrator_account_name: core-security
        environment: ue1
        region: us-east-1

atmos terraform apply security-hub/delegated-administrator/ue1 -s core-ue1-security
atmos terraform apply security-hub/delegated-administrator/ue2 -s core-ue2-security
atmos terraform apply security-hub/delegated-administrator/uw1 -s core-uw1-security
# ... other regions

Deploy to Organization Management (root) Account

Next, the component is deployed to the AWS Organization Management (a/k/a root) Account in order to set the AWS Organization Designated Administrator account.

Note that SuperAdmin permissions must be used as we are deploying to the AWS Organization Management account. Since we are using the SuperAdmin user, it will already have access to the state bucket, so we set the role_arn of the backend config to null and set var.privileged to true.

# core-ue1-root
components:
  terraform:
    security-hub/root/ue1:
      metadata:
        component: security-hub
    backend:
      s3:
        role_arn: null
      vars:
        enabled: true
        delegated_administrator_account_name: core-security
        environment: ue1
        region: us-east-1
        privileged: true

atmos terraform apply security-hub/root/ue1 -s core-ue1-root
atmos terraform apply security-hub/root/ue2 -s core-ue2-root
atmos terraform apply security-hub/root/uw1 -s core-uw1-root
# ... other regions

Deploy Organization Settings in Delegated Administrator Account

Finally, the component is deployed to the Delegated Administrator Account again in order to create the organization-wide Security Hub configuration for the AWS Organization, but with var.admin_delegated set to true this time to indicate that the delegation from the Organization Management account has already been performed.

# core-ue1-security
components:
  terraform:
    security-hub/org-settings/ue1:
      metadata:
        component: security-hub
      vars:
        enabled: true
        delegated_administrator_account_name: core-security
        environment: use1
        region: us-east-1
        admin_delegated: true

atmos terraform apply security-hub/org-settings/ue1 -s core-ue1-security
atmos terraform apply security-hub/org-settings/ue2 -s core-ue2-security
atmos terraform apply security-hub/org-settings/uw1 -s core-uw1-security

This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration.	`map(string)`	`{}`	no
admin_delegated	A flag to indicate if the AWS Organization-wide settings should be created. This can only be done after the Security Hub Admininstrator account has already been delegated from the AWS Org Management account (usually 'root').

Values are maps of the form `{<br/> format = string<br/> labels = list(string)<br/>}` (Type is `any` so the map values can later be enhanced to provide additional options.) `format` is a Terraform format string to be passed to the `format()` function. `labels` is a list of labels, in order, to pass to `format()` function. Label values will be normalized before being passed to `format()` so they will be identical to how they appear in `id`. Default is `{}` (`descriptors` output will be empty).	`any`	`{}`	no
enabled	Set to false to prevent the module from creating any resources	`bool`	`null`	no
enabled_standards	A list of standards to enable in the account. For example: - standards/aws-foundational-security-best-practices/v/1.0.0 - ruleset/cis-aws-foundations-benchmark/v/1.2.0 - standards/pci-dss/v/3.2.1 - standards/cis-aws-foundations-benchmark/v/1.4.0	`set(string)`	`[]`	no
