- effect string (optional): Either "Allow" or "Deny", to specify whether this statement allows or denies the given actions.
- actions list(string) (optional): A list of actions that this statement either allows or denies. For example, ["s3:GetObject", "s3:PutObject"].
- not_actions list(string) (optional): A list of actions that this statement does NOT apply to. Used to apply a policy statement to all actions except those listed.
- principals map(list(string)) (optional): The principals to which this statement applies. The keys are the principal type ("AWS", "Service", or "Federated") and the value is a list of identifiers.
- not_principals map(list(string)) (optional): The principals to which this statement does NOT apply. The keys are the principal type ("AWS", "Service", or "Federated") and the value is a list of identifiers.
- keys list(string) (optional): A list of keys within the bucket to which this policy applies. For example, ["", "/*"] would apply to (a) the bucket itself and (b) all keys within the bucket. The default is [""].
- condition map(object) (optional): A nested configuration block (described below) that defines a further, possibly-service-specific condition that constrains whether this statement applies.
condition is a map from a unique ID for the condition to an object that can define the following properties:
- test string (required): The name of the IAM condition operator to evaluate.
- variable string (required): The name of a Context Variable to apply the condition to. Context variables may either be standard AWS variables starting with aws:, or service-specific variables prefixed with the service name.
- values list(string) (required): The values to evaluate the condition against. If multiple values are provided, the condition matches if at least one of them applies. (That is, the tests are combined with the "OR" boolean operation.)

Ideally, this would be a map(object({...})), but the Terraform object type constraint doesn't support optional
parameters, whereas IAM policy statements have many optional params. And we can't even use map(any), as the
Terraform map type constraint requires all values to have the same type ("shape"), but as each object in the map
may specify different optional params, this won't work either. So, sadly, we are forced to fall back to "any."
Whether or not to allow kms:DescribeKey to external AWS accounts with write access to the CloudTrail bucket. This is useful during deployment so that you don't have to pass around the KMS key ARN.
false
Specify the name of the CloudWatch Logs group to publish the CloudTrail logs to. This log group exists in the current account. Set this value to null
to avoid publishing the trail logs to the logs group. The recommended configuration for CloudTrail is (a) for each child account to aggregate its logs in an S3 bucket in a single central account, such as a logs account and (b) to also store 14 days work of logs in CloudWatch in the child account itself for local debugging.
"cloudtrail-logs"
If true, logging of data events will be enabled.

invalid_cmk_inputs output.
- replica_regions list(string) : The regions (e.g., us-west-2) where the key should be replicated using the
multi-region KMS key feature of AWS
(https://docs.aws.amazon.com/kms/latest/developerguide/multi-region-keys-overview.html).
When the special region "*" is included (e.g., replica_regions = ["*"]),
the key will be replicated in all enabled regions. This is different from
creating the key in every region using region = null - when creating
the key in every region, a new different key is provisioned for each region.
With replica_regions, the same key is replicated in every region such that
it can decrypt the same encrypted data in each region.
- cmk_administrator_iam_arns list(string) : A list of IAM ARNs for users who should be given
administrator access to this CMK (e.g.
arn:aws:iam::<aws-account-id>:user/<iam-user-arn>).
- cmk_user_iam_arns list(object[CMKUser]) : A list of IAM ARNs for users who should be given
permissions to use this CMK (e.g.
arn:aws:iam::<aws-account-id>:user/<iam-user-arn>).
- cmk_read_only_user_iam_arns list(object[CMKUser]) : A list of IAM ARNs for users who should be given
read-only (decrypt-only) permissions to use this CMK (e.g.
arn:aws:iam::<aws-account-id>:user/<iam-user-arn>).
- cmk_external_user_iam_arns list(string) : A list of IAM ARNs for users from external AWS accounts
who should be given permissions to use this CMK (e.g.
arn:aws:iam::<aws-account-id>:root).
- allow_manage_key_permissions_with_iam bool : If true, both the CMK's Key Policy and IAM Policies
(permissions) can be used to grant permissions on the CMK.
If false, only the CMK's Key Policy can be used to grant
permissions on the CMK. False is more secure (and
generally preferred), but true is more flexible and
convenient.
- deletion_window_in_days number : The number of days to keep this KMS Master Key around after it has been
marked for deletion.
- tags map(string) : A map of tags to apply to the KMS Key to be created. In this map
variable, the key is the tag name and the value is the tag value. Note
that this map is merged with var.global_tags, and can be used to override
tags specified in that variable.
- enable_key_rotation bool : Whether or not to enable automatic annual rotation of the KMS key.
- spec string : Specifies whether the key contains a symmetric key or an asymmetric key
pair and the encryption algorithms or signing algorithms that the key
supports. Valid values: SYMMETRIC_DEFAULT, RSA_2048, RSA_3072, RSA_4096,
ECC_NIST_P256, ECC_NIST_P384, ECC_NIST_P521, or ECC_SECG_P256K1.
- cmk_service_principals list(object[ServicePrincipal]) : A list of Service Principals that should be given
permissions to use this CMK (e.g. s3.amazonaws.com). See
below for the structure of the object that should be passed
in.
Structure of ServicePrincipal object:
- name string : The name of the service principal (e.g.: s3.amazonaws.com).
- actions list(string) : The list of actions that the given service principal is allowed to
perform (e.g. ["kms:DescribeKey", "kms:GenerateDataKey"]).
- conditions list(object[Condition]) : (Optional) List of conditions to apply to the permissions for the service
principal. Use this to apply conditions on the permissions for
accessing the KMS key (e.g., only allow access for certain encryption
contexts). The condition object accepts the same fields as the condition
block on the IAM policy document (See
https://www.terraform.io/docs/providers/aws/d/iam_policy_document.htmlcondition).
Structure of CMKUser object:
- name list(string) : The list of names of the AWS principal (e.g.: arn:aws:iam::0000000000:user/dev).
- conditions list(object[Condition]) : (Optional) List of conditions to apply to the permissions for the CMK User
Use this to apply conditions on the permissions for accessing the KMS key
(e.g., only allow access for certain encryption contexts).
The condition object accepts the same fields as the condition
block on the IAM policy document (See
https://www.terraform.io/docs/providers/aws/d/iam_policy_document.htmlcondition).

kms_grant_regions
map(string)The map of names of KMS grants to the region where the key resides in. There should be a one to one mapping between entries in this map and the entries of the kms_grants map. This is used to workaround a terraform limitation where the for_each value can not depend on resources.

- DAILY
You can also override the recording frequency for specific resource types. recording_mode_override: description: A description for the override. recording_frequency: The frequency with which AWS Config records configuration changes for the specified resource types.
- CONTINUOUS
- DAILY resource_types: A list of resource types for which AWS Config records configuration changes. For example, AWS::EC2::Instance.

null
service_linked_roles
set(string)Create service-linked roles for this set of services. You should pass in the URLs of the services, but without the protocol (e.g., http://) in front: e.g., use elasticbeanstalk.amazonaws.com for Elastic Beanstalk or es.amazonaws.com for Amazon Elasticsearch. Service-linked roles are predefined by the service, can typically only be assumed by that service, and include all the permissions that the service requires to call other AWS services on your behalf. You can typically only create one such role per AWS account, which is why this parameter exists in the account baseline. See https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html for the list of services that support service-linked roles.
[]
Should we require that all IAM Users use Multi-Factor Authentication for both AWS API calls and the AWS Web Console? (true or false)
true
When true, all IAM policies will be managed as dedicated policies rather than inline policies attached to the IAM roles. Dedicated managed policies are friendlier to automated policy checkers, which may scan a single resource for findings. As such, it is important to avoid inline policies when targeting compliance with various security standards.
