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.
Key Features
-
Centralized Security Management: Provides a centralized dashboard where users can view and manage security findings from multiple AWS accounts and regions, allowing for a unified view of the security posture across the entire AWS environment.
-
Automated Security Checks: Automatically performs continuous security checks on AWS resources, configurations, and security best practices using industry standards and compliance frameworks such as AWS CIS Foundations Benchmark.
-
Product Subscriptions: Integrates with AWS security services (GuardDuty, Inspector, Macie, Config, Access Analyzer, Firewall Manager) to automatically receive and aggregate findings in a single dashboard.
-
Security Standards and Compliance: Provides compliance checks against industry standards and regulatory frameworks such as PCI DSS, HIPAA, NIST 800-53, and GDPR, with guidance on remediation actions.
-
Prioritized Security Findings: Analyzes and prioritizes security findings based on severity, enabling users to focus on the most critical issues with efficient threat response and remediation.
-
Custom Insights and Event Aggregation: Supports custom insights and rules to focus on specific security criteria, with event aggregation and correlation capabilities to identify related findings and attack patterns.
-
Alert Notifications and Automation: Supports alert notifications through Amazon SNS and facilitates automation through integration with AWS Lambda for automated remediation actions.
-
GovCloud Support: All product subscription ARNs use partition-aware format, automatically supporting both Commercial AWS and GovCloud partitions.
Component Features
- Delegated Administrator Model: Uses AWS Organizations delegated administrator pattern for centralized management
- Organizations Delegation Policy: Automatically creates the 8-statement Organizations resource-based delegation policy required for Security Hub console access in the delegated administrator account
- Multi-Region Deployment: Supports deployment across all AWS regions with finding aggregation
- Product Subscriptions: Automatically creates subscriptions for AWS security service integrations
- SNS Notifications: Optional SNS topic creation for security finding alerts
- Compliance Standards: Configurable security standards (CIS, PCI DSS, AWS Foundational Security Best Practices)
- Account Verification: Optional safety check that validates Terraform is running in the correct AWS account
- Flexible Account Map: Supports both remote-state account-map lookups and static account map variables (default)
Usage
Stack Level: Regional
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-use1-security
components:
terraform:
aws-security-hub/delegated-administrator:
metadata:
component: aws-security-hub
vars:
enabled: true
delegated_administrator_account_name: core-security
# Product subscriptions for AWS security service integrations
product_subscriptions:
guardduty: true # Enable GuardDuty findings
inspector: true # Enable Inspector findings
macie: false # Disabled by default - enable if using Macie
config: true # Enable Config findings
access_analyzer: true # Enable Access Analyzer findings
firewall_manager: false # Disabled by default
atmos terraform apply aws-security-hub/delegated-administrator -s core-use1-security
atmos terraform apply aws-security-hub/delegated-administrator -s core-use2-security
atmos terraform apply aws-security-hub/delegated-administrator -s core-usw1-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. This step also creates the
Organizations resource-based delegation policy
that grants the delegated administrator permissions to manage Security Hub policies via Organizations APIs.
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-use1-root
components:
terraform:
aws-security-hub/root:
metadata:
component: aws-security-hub
vars:
enabled: true
delegated_administrator_account_name: core-security

atmos terraform apply aws-security-hub/root -s core-use1-root
atmos terraform apply aws-security-hub/root -s core-use2-root
atmos terraform apply aws-security-hub/root -s core-usw1-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. This step uses LOCAL
configuration mode where each account manages its own configuration, and auto-enables Security Hub for all member
accounts.
# core-use1-security
components:
terraform:
aws-security-hub/org-settings:
metadata:
component: aws-security-hub
vars:
enabled: true
delegated_administrator_account_name: core-security
admin_delegated: true
atmos terraform apply aws-security-hub/org-settings -s core-use1-security
atmos terraform apply aws-security-hub/org-settings -s core-use2-security
atmos terraform apply aws-security-hub/org-settings -s core-usw1-security
# ... other regions
Product Subscriptions
Product subscriptions enable Security Hub to receive and aggregate findings from AWS security services. The component supports automatic integration with:
| Product | Default | Description |
|---|---|---|
| GuardDuty | true | Threat detection findings |
| Inspector | true | Vulnerability scanning findings |
| Macie | false | Sensitive data discovery findings |
| Config | true | Configuration compliance findings |
| Access Analyzer | true | External access findings |
| Firewall Manager | false | Firewall policy compliance findings |
Product subscriptions are only created during Step 1 (delegated administrator deployment) and use partition-aware ARN format for GovCloud compatibility.
Verification
After deployment, verify product subscriptions:
# Via Terraform output
atmos terraform output aws-security-hub/delegated-administrator -s core-use1-security
# Via AWS CLI
aws securityhub list-enabled-products-for-import --region us-east-1
Delegation Policy
Step 2 (root account deployment) creates an Organizations resource-based delegation policy with 8 policy statements that grant the delegated administrator account permissions to manage Security Hub policies via Organizations APIs. This policy is required even when using LOCAL configuration mode, because the Security Hub console checks for it when displaying central configuration management options.
Key details:
- The policy uses
organizations:*actions (notsecurityhub:*). Organizations resource policies only supportorganizations:*actions. - AWS expects exactly 8 policy statements, including
SecurityServicesDelegating*statements with resource ARNs scoped to the organization ID. - The policy includes resources for both
securityhub_policyandinspector_policytypes (shared delegation mechanism). aws_organizations_resource_policyis an organization-wide singleton. Only one can exist per organization. If other services need delegation policies, their statements must be combined into a single policy.- Set
organizations_resource_policy_enabled = falseif the Organizations resource policy is managed by another component or service.
Troubleshooting: "Missing Permissions to Manage Policies"
If the delegated administrator sees this error in the Security Hub console:
You are missing permissions that are required to manage policies in Security Hub.
This means the Organizations resource-based delegation policy is missing or incomplete. Re-apply Step 2:
atmos terraform apply aws-security-hub/root -s core-use1-root
Account Map Configuration
The component supports two modes for resolving AWS account IDs:
Static Mode (default)
When account_map_enabled = false (default), the component uses a static account_map variable instead of remote state. This is
useful when not using the account-map component or when account mappings are managed externally (e.g., by Atmos).
Remote State Mode
When account_map_enabled = true, the component fetches account mappings from the account-map component
via Terraform remote state. This is the standard Cloud Posse reference architecture pattern.
vars:
account_map_enabled: false
account_map:
full_account_map:
core-root: "111111111111"
core-security: "222222222222"
core-audit: "333333333333"
plat-dev: "444444444444"
plat-prod: "555555555555"
root_account_account_name: "core-root"
When using static mode, provider authentication is handled externally (e.g., by Atmos identity resolution) rather than
through the iam-roles module.
Account Verification
When account_verification_enabled = true (default), the component verifies that Terraform is executing in the correct
AWS account by comparing the current account ID against the expected account ID from the account map, based on the
component's tenant-stage context. This provides a safety check to catch misconfigurations before any resources are
created or modified.
To disable account verification:
vars:
account_verification_enabled: false
