Data Lake Permissions That Are Actually in Effect
AWS Lake Formation with its own permissions switched on for new databases and tables: admins, registered S3 locations and explicit grants. AWS ships it in IAM-only mode, and its settings resource clears any admin it is not given, so admins are required and the settings are protected from destroy. Existing databases keep IAM-only access until revoked outside Terraform, and it says so.

Documentation
aws-lake-formation
Data lake permissions that take effect on AWS Lake Formation. Works with Terraform and OpenTofu
(>= 1.6), aws provider >= 6.0, < 7.0.
Out of the box, Lake Formation permissions do nothing. AWS grants Super to IAMAllowedPrincipals on existing catalog resources and uses IAM-only control for new ones. This module moves NEW databases and tables to Lake Formation control; existing ones keep their IAMAllowedPrincipals grant until revoked in the console or CLI, and existing_resources_changed says false.
The settings resource clears what it is not given, so admins and cross_account_version are required.
Destroying the settings removes every admin. They are protected from destroy; stop managing them with tofu state rm.
Grants to admins or to IAMAllowedPrincipals are refused: admins hold implicit permissions, and the provider warns that mixing IAMAllowedPrincipals with individual grants gives unexpected results.
A location registered with a role stays with a role: AWS does not support switching it to the service-linked role later.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.

aws-verified-permissions
validation_settings.mode defaults to OFF, so a Cedar policy naming an action the schema does not define is accepted and then never matches. A broken permit fails closed and somebody complains; a broken forbid fails OPEN and nobody does. STRICT here, with the schema that makes it possible.
aws-rolesanywhere
Any certificate chaining to the trust anchor can exchange itself for AWS credentials, so the CA is the perimeter - and it is usually run by people who were never told. The profile carries the scope, sessions are narrowed below the role, the caller cannot name itself in CloudTrail, and CA expiry warns before every workload loses credentials at once.
aws-signer
Signing profiles for Lambda packages and container images, plus the code signing configuration that enforces them. Defaults to Enforce rather than the API default Warn, which logs an untrusted artifact and deploys it anyway.
aws-cognito
A secure-by-default Cognito user pool and app client with optional hosted-UI domain - strong password policy, TOTP MFA, account-enumeration protection, SRP-only flows, and refresh-token revocation.
aws-conformance-packs
AWS Config conformance packs for one account or a whole organisation, with a ten-rule baseline of AWS managed rules taken from AWS's CIS sample pack. AWS Audit Manager no longer takes new customers and points them here. The module says a pack evaluates nothing without a configuration recorder and that Terraform cannot detect a pack edited in the console.
aws-detective
Builds an investigable graph from CloudTrail, VPC flow logs and GuardDuty findings, with member accounts and organization delegation. It detects nothing itself - it makes an existing finding into a timeline.
