Account Baseline for security account
Overview
A security baseline for AWS Landing Zone for configuring the security account (the one where all your IAM users and IAM groups are defined), including setting up AWS Config, AWS CloudTrail, Amazon Guard Duty, IAM users, IAM groups, IAM password policy, and more.
For large scale organizations that frequently onboard and offboard new users, consider taking a look at the iam-users-and-groups module for managing IAM Users and Groups.
Features
Get a secure baseline for the security account of your AWS Organization that includes:
- aws-config-multi-region
- cloudtrail
- cross-account-iam-roles
- guardduty-multi-region
- iam-groups
- iam-users
- iam-user-password-policy

Otherwise, we won't know which regions to use and authenticate to, and may use some not enabled in your AWS account (e.g., GovCloud, China, etc). To get the list of regions enabled in your AWS account, you can use the AWS CLI: aws ec2 describe-regions. The value provided for global_recorder_region must be in this list.
guardduty_opt_in_regions
list(string)Creates resources in the specified regions. The best practice is to enable GuardDuty in all enabled regions in your AWS account. This variable must NOT be set to null or empty. Otherwise, we won't know which regions to use and authenticate to, and may use some not enabled in your AWS account (e.g., GovCloud, China, etc). To get the list of regions enabled in your AWS account, you can use the AWS CLI: aws ec2 describe-regions. The value provided for global_recorder_region must be in this list.

null
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.

[]
cloudtrail_kms_key_arn
stringAll CloudTrail Logs will be encrypted with a KMS CMK (Customer Master Key) that governs access to write API calls older than 7 days and all read API calls. If that CMK already exists, set this to the ARN of that CMK. Otherwise, set this to null, and a new CMK will be created. We recommend setting this to the ARN of a CMK that already exists in a separate logs account.
null
If the kms_key_arn provided is an alias or alias ARN, then this must be set to true so that the module will exchange the alias for a CMK ARN. Setting this to true and using aliases requires cloudtrail_allow_kms_describe_key_to_external_aws_accounts
to also be true for multi-account scenarios.

[]
cloudtrail_kms_key_user_iam_arns
list(string)All CloudTrail Logs will be encrypted with a KMS Key (a Customer Master Key) that governs access to write API calls older than 7 days and all read API calls. The IAM Users specified in this list will have read-only access to this extended log data.
[]
After this number of days, log files should be transitioned from S3 to Glacier. Enter 0 to never archive log data.
30
After this number of days, log files should be deleted from S3. Enter 0 to never delete log data.
365

0
Set to false to create an S3 bucket of name cloudtrail_s3_bucket_name
in this account for storing CloudTrail logs. Set to true to assume the bucket specified in cloudtrail_s3_bucket_name
already exists in another AWS account. We recommend setting this to true and setting cloudtrail_s3_bucket_name
to the name of a bucket that already exists in a separate logs account.
false
The name of the S3 Bucket where CloudTrail logs will be stored. If value is null
, defaults to <a href="#name_prefix"><code>name_prefix</code></a>
-cloudtrail
null
Enable MFA delete for either 'Change the versioning state of your bucket' or 'Permanently delete an object version'. This setting only applies to the bucket used to storage Cloudtrail data. This cannot be used to toggle this setting but is available to allow managed buckets to reflect the state in AWS. For instructions on how to enable MFA Delete, check out the README from the terraform-aws-security/private-s3-bucket module.
false
cloudtrail_tags
map(string)Tags to apply to the CloudTrail resources.
{}
Set to true to send the AWS Config data to another account (e.g., a logs account) for aggregation purposes. You must set the ID of that other account via the config_central_account_id variable. This redundant variable has to exist because Terraform does not allow computed data in count and for_each parameters and config_central_account_id
may be computed if its the ID of a newly-created AWS account.
false
If the S3 bucket and SNS topics used for AWS Config live in a different AWS account, set this variable to the ID of that account. If the S3 bucket and SNS topics live in this account, set this variable to null. We recommend setting this to the ID of a separate logs account. Only used if config_aggregate_config_data_in_external_account
is true.
null
Set to true to create AWS Config rules directly in this account. Set false to not create any Config rules in this account (i.e., if you created the rules at the organization level already). We recommend setting this to true to use account-level rules because org-level rules create a chicken-and-egg problem with creating new accounts.
true
Optional KMS key to use for encrypting S3 objects on the AWS Config delivery channel for an externally managed S3 bucket. This must belong to the same region as the destination S3 bucket. If null, AWS Config will default to encrypting the delivered data with AES-256 encryption. Only used if should_create_s3_bucket
is false - otherwise, kms_key_arn
is used.
null
Same as config_delivery_channel_kms_key_arn
, except the value is a name of a KMS key configured with kms_customer_master_keys
. The module created KMS key for the delivery region (indexed by the name) will be used. Note that if both config_delivery_channel_kms_key_arn
and config_delivery_channel_kms_key_by_name
are configured, the key in config_delivery_channel_kms_key_arn
will always be used.
object({
name = string

After this number of days, log files should be deleted from S3. Enter 0 to never delete log data.
730
Optional KMS key to use for encrypting S3 objects on the AWS Config bucket, when the S3 bucket is created within this module (config_should_create_s3_bucket
is true). For encrypting S3 objects on delivery for an externally managed S3 bucket, refer to the config_delivery_channel_kms_key_arn
input variable. If null, data in S3 will be encrypted using the default aws/s3 key. If provided, the key policy of the provided key must permit the IAM role used by AWS Config. See https://docs.aws.amazon.com/sns/latest/dg/sns-key-management.html. Note that the KMS key must reside in the global recorder region (as configured by aws_region
).
null
Same as config_s3_bucket_kms_key_arn
, except the value is a name of a KMS key configured with kms_customer_master_keys
. The module created KMS key for the global recorder region (indexed by the name) will be used. Note that if both config_s3_bucket_kms_key_arn
and config_s3_bucket_kms_key_by_name
are configured, the key in config_s3_bucket_kms_key_arn
will always be used.
null
config_s3_bucket_name
stringThe name of the S3 Bucket where CloudTrail logs will be stored. This could be a bucket in this AWS account or the name of a bucket in another AWS account where logs should be sent. We recommend setting this to the name of a bucket in a separate logs account.
null
Enable MFA delete for either 'Change the versioning state of your bucket' or 'Permanently delete an object version'. This setting only applies to the bucket used to storage AWS Config data. This cannot be used to toggle this setting but is available to allow managed buckets to reflect the state in AWS. For instructions on how to enable MFA Delete, check out the README from the terraform-aws-security/private-s3-bucket module.
false
Set to true to create an S3 bucket of name config_s3_bucket_name
in this account for storing AWS Config data. Set to false to assume the bucket specified in config_s3_bucket_name
already exists in another AWS account. We recommend setting this to false and setting config_s3_bucket_name
to the name off an S3 bucket that already exists in a separate logs account.
false
Set to true to create an SNS topic in this account for sending AWS Config notifications (e.g., if this is the logs account). Set to false to assume the topic specified in config_sns_topic_name
already exists in another AWS account (e.g., if this is the stage or prod account and config_sns_topic_name
is the name of an SNS topic in the logs account).
false
config_sns_topic_kms_key_by_name_region_map
map(string)Same as config_sns_topic_kms_key_region_map
, except the value is a name of a KMS key configured with kms_customer_master_keys
. The module created KMS key for each region (indexed by the name) will be used. Note that if an entry exists for a region in both config_sns_topic_kms_key_region_map
and config_sns_topic_kms_key_by_name_region_map
, then the key in config_sns_topic_kms_key_region_map
will always be used.
null
config_sns_topic_kms_key_region_map
map(string)Optional KMS key to use for each region for configuring default encryption for the SNS topic (encoded as a map from region - e.g. us-east-1 - to ARN of KMS key). If null or the region key is missing, encryption will not be configured for the SNS topic in that region.

dev_permitted_services
list(string)A list of AWS services for which the developers from the accounts in allow_dev_access_from_other_account_arns
will receive full permissions. See https://goo.gl/ZyoHlz to find the IAM Service name. For example, to grant developers access only to EC2 and Amazon Machine Learning, use the value ['ec2','machinelearning']. Do NOT add iam to the list of services, or that will grant Developers de facto admin access.
[]
If set to true (default), all new EBS volumes will have encryption enabled by default
true
ebs_kms_key_name
stringThe name of the KMS CMK to use by default for encrypting EBS volumes, if ebs_enable_encryption
and ebs_use_existing_kms_keys
are enabled. The name must match a name given the kms_customer_master_keys
variable.
""
If set to true, the KMS Customer Managed Keys (CMK) with the name in ebs_kms_key_name
will be set as the default for EBS encryption. When false (default), the AWS-managed aws/ebs key will be used.
false
Set to true (default) to enable CloudTrail in the security account. Set to false to disable CloudTrail (note: all other CloudTrail variables will be ignored). Note that if you have enabled organization trail in the root (parent) account, you should set this to false; the organization trail will enable CloudTrail on child accounts by default.

false
When set, use the statically provided hardcoded list of thumbprints rather than looking it up dynamically. This is useful if you want to trade reliability of the OpenID Connect Provider across certificate renewals with a static list that is obtained using a trustworthy mechanism, to mitigate potential damage from a domain hijacking attack on GitHub domains.
null
Name of the Cloudwatch event rules.
"guardduty-finding-events"
Specifies the frequency of notifications sent for subsequent finding occurrences. If the detector is a GuardDuty member account, the value is determined by the GuardDuty master account and cannot be modified, otherwise defaults to SIX_HOURS.

kms_cmk_global_tags
map(string)A map of tags to apply to all KMS Keys to be created. In this map variable, the key is the tag name and the value is the tag value.
{}
You can use this variable to create account-level KMS Customer Master Keys (CMKs) for encrypting and decrypting data. This variable should be a map where the keys are the names of the CMK and the values are an object that defines the configuration for that CMK. See the comment below for the configuration options you can set for each key.
Any types represent complex values of variable type. For details, please consult `variables.tf` in the source repo.
{}
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.
{}
kms_grants
map(object(…))Create the specified KMS grants to allow entities to use the KMS key without modifying the KMS policy or IAM. This is necessary to allow AWS services (e.g. ASG) to use CMKs encrypt and decrypt resources. The input is a map of grant name to grant properties. The name must be unique per account.
map(object({
# ARN of the KMS CMK that the grant applies to. Note that the region is introspected based on the ARN.
kms_cmk_arn = string
# The principal that is given permission to perform the operations that the grant permits. This must be in ARN
# format. For example, the grantee principal for ASG is:
# arn:aws:iam::111122223333:role/aws-service-role/autoscaling.amazonaws.com/AWSServiceRoleForAutoScaling
grantee_principal = string
# A list of operations that the grant permits. The permitted values are:
# Decrypt, Encrypt, GenerateDataKey, GenerateDataKeyWithoutPlaintext, ReEncryptFrom, ReEncryptTo, CreateGrant,
# RetireGrant, DescribeKey
granted_operations = list(string)

true
KMS key ID or ARN used to encrypt the storage. Used for configuring the RDS storage encryption config rule.
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.

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.
true
users
anyA map of users to create. The keys are the user names and the values are an object with the optional keys 'groups' (a list of IAM groups to add the user to), 'tags' (a map of tags to apply to the user), 'pgp_key' (either a base-64 encoded PGP public key, or a keybase username in the form keybase:username, used to encrypt the user's credentials; required if create_login_profile or create_access_keys is true), 'create_login_profile' (if set to true, create a password to login to the AWS Web Console), 'create_access_keys' (if set to true, create access keys for the user), 'path' (the path), and 'permissions_boundary' (the ARN of the policy that is used to set the permissions boundary for the user).
Any types represent complex values of variable type. For details, please consult `variables.tf` in the source repo.
