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
privileged: true
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:

ProductDefaultDescription
GuardDutytrueThreat detection findings
InspectortrueVulnerability scanning findings
MaciefalseSensitive data discovery findings
ConfigtrueConfiguration compliance findings
Access AnalyzertrueExternal access findings
Firewall ManagerfalseFirewall 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 (not securityhub:*). Organizations resource policies only support organizations:* 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_policy and inspector_policy types (shared delegation mechanism).
  • aws_organizations_resource_policy is 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 = false if 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

Variables

Required Variables

region (string) required

AWS Region

Optional Variables

account_map optional

Static account map configuration. Only used when account_map_enabled is false.
Map keys use tenant-stage format (e.g., core-security, core-audit, plat-prod).

A list of regions to aggregate findings from.


This is only used if finding_aggregator_enabled is true.



Default value: null

findings_notification_arn (string) optional

The ARN for an SNS topic to send findings notifications to. This is only used if create_sns_topic is false.
If you want to send findings to an existing SNS topic, set this to the ARN of the existing topic and set
create_sns_topic to false.

Default value: null

organizations_resource_policy_enabled (bool) optional

Enable creation of the Organizations resource-based delegation policy for Security Hub. When true (default),
the component creates an aws_organizations_resource_policy in the management account (Step 2) that grants the
delegated administrator permissions to manage Security Hub policies via Organizations APIs.


Set to false if the Organizations resource policy is managed elsewhere (e.g., by another component or service).
Note: aws_organizations_resource_policy is an organization-wide singleton — only one can exist per organization.
If other services (e.g., AWS Backup, Inspector) need delegation policies, their statements must be combined into
a single policy managed by one component.



Default value: true

privileged (bool) optional

true if the default provider already has access to the backend


Default value: false

Default value: { }

attributes (list(string)) optional

ID element. Additional attributes (e.g. workers or cluster) to add to id,
in the order they appear in the list. New attributes are appended to the
end of the list. The elements of the list are joined by the delimiter
and treated as a single ID element.


Required: No

Default value: [ ]

context (any) optional

Single object for setting entire context at once.
See description of individual variables for details.
Leave string and numeric variables as null to use default value.
Individual variable settings (non-null) override settings in context object,

(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).

enabled (bool) optional

Set to false to prevent the module from creating any resources
Required: No

Default value: null

Controls the letter case of ID elements (labels) as included in id,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the tags input.
Possible values: lower, title, upper and none (no transformation).
Set this to title and set delimiter to &#34;&#34; to yield Pascal Case IDs.
Default value: lower.


Required: No

Default value: null

labels_as_tags (set(string)) optional

Set of labels (ID elements) to include as tags in the tags output.
Default is to include all labels.
Tags with empty values will not be included in the tags output.
Set to [] to suppress all generated tags.
Notes:
