This component is responsible for configuring Macie within an AWS Organization.

Amazon Macie is a data security service that discovers sensitive data by using machine learning and pattern matching, provides visibility into data security risks, and enables automated protection against those risks.

To help you manage the security posture of your organization's Amazon Simple Storage Service (Amazon S3) data estate, Macie provides you with an inventory of your S3 buckets, and automatically evaluates and monitors the buckets for security and access control. If Macie detects a potential issue with the security or privacy of your data, such as a bucket that becomes publicly accessible, Macie generates a finding for you to review and remediate as necessary.

Macie also automates discovery and reporting of sensitive data to provide you with a better understanding of the data that your organization stores in Amazon S3. To detect sensitive data, you can use built-in criteria and techniques that Macie provides, custom criteria that you define, or a combination of the two. If Macie detects sensitive data in an S3 object, Macie generates a finding to notify you of the sensitive data that Macie found.

In addition to findings, Macie provides statistics and other data that offer insight into the security posture of your Amazon S3 data, and where sensitive data might reside in your data estate. The statistics and data can guide your decisions to perform deeper investigations of specific S3 buckets and objects. You can review and analyze findings, statistics, and other data by using the Amazon Macie console or the Amazon Macie API. You can also leverage Macie integration with Amazon EventBridge and AWS Security Hub to monitor, process, and remediate findings by using other services, applications, and systems.

Deployment Overview

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

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 to configure the central Macie account∑.

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

atmos terraform apply macie/delegated-administrator -s core-ue1-security

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 you must SuperAdmin permissions 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:
    guardduty/root:
      metadata:
        component: macie
    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 macie/root -s core-ue1-root

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 configuration for the AWS Organization, but with var.admin_delegated set to true to indicate that the delegation has already been performed from the Organization Management account.

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

atmos terraform apply macie/org-settings/ue1 -s core-ue1-security

Inputs

Name	Description	Type	Default	Required
account_map_tenant	The tenant where the account_map component required by remote-state is deployed	string	"core"	no
additional_tag_map	Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id. 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 GuardDuty Administrator account has already been delegated from the AWS Org Management account (usually 'root'). See the Deployment section of the README for more information.	bool	false	no
attributes	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.	list(string)	[]	no
context	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, except for attributes, tags, and additional_tag_map, which are merged.	any	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "descriptor_formats": {}, "enabled": true, "environment": null, "id_length_limit": null, "label_key_case": null, "label_order": [], "label_value_case": null, "labels_as_tags": [ "unset" ], "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {}, "tenant": null }	no
delegated_admininstrator_component_name	The name of the component that created the Macie account.	string	"macie/delegated-administrator"	no
delegated_administrator_account_name	The name of the account that is the AWS Organization Delegated Administrator account	string	"core-security"	no
delimiter	Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
descriptor_formats	Describe additional descriptors to be output in the descriptors output map. Map of maps. Keys are names of descriptors. 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
environment	ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'	string	null	no
finding_publishing_frequency	Specifies how often to publish updates to policy findings for the account. This includes publishing updates to AWS Security Hub and Amazon EventBridge (formerly called Amazon CloudWatch Events).

label_order	The order in which the labels (ID elements) appear in the id. Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.	list(string)	null	no
label_value_case	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 "" to yield Pascal Case IDs. Default value: lower.	string	null	no
labels_as_tags	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: The value of the name tag, if included, will be the id, not the name. Unlike other null-label inputs, the initial setting of labels_as_tags cannot be changed in later chained modules. Attempts to change it will be silently ignored.	set(string)	[ "default" ]	no
member_accounts	List of member account names to enable Macie on	list(string)	[]	no
name	ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'. This is the only ID element not also included as a tag. The "name" tag is set to the full id string. There is no tag with the value of the name input.	string	null	no
