A Database Proxy Where No Client Holds the Password
Amazon RDS Proxy in front of an RDS instance or Aurora cluster: TLS required, clients authenticate with IAM tokens while the proxy reads the password from Secrets Manager, through a role limited to those secrets. Debug logging writes SQL statement text to the logs, so it is off unless that is accepted. End-to-end IAM removes the stored password entirely.

Documentation
aws-database-proxy
A database connection proxy on Amazon RDS Proxy. Works with Terraform and OpenTofu
(>= 1.6), aws provider >= 6.0, < 7.0.
Debug logging puts your SQL in CloudWatch. The provider documents that it logs the text of SQL statements sent through the proxy. Off by default; on needs accept_sql_text_in_logs.
A password shared by every client is not an identity. Clients use short-lived IAM tokens and the proxy holds the database password (AWS's standard IAM authentication). end_to_end_iam removes the stored password entirely.
TLS is required for connections to the proxy.
The proxy's role reads exactly the secrets it is given, with KMS decrypt allowed only through Secrets Manager when a customer managed key is used.
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.

Related modules
aws-keyspaces
point_in_time_recovery defaults to DISABLED and Keyspaces has no snapshots or automated backups, so off means a dropped table is simply gone. PITR on, a customer-managed key, and the two one-way doors - client-side timestamps and TTL - named rather than set quietly.
aws-dax-cache
DynamoDB Accelerator with TLS and encryption at rest. DAX leaves both off by default, and neither can be turned on for an existing cluster, so a fix means a new cluster. This module also creates its own security group (DAX otherwise uses the VPC default), a service role limited to the named tables and their indexes, and states that writes bypassing DAX leave stale reads until the TTL.
aws-neptune
Neptune has no user, no password and no GRANT. Authorization is IAM and it defaults to OFF, so anything that can reach port 8182 can read every edge and drop the lot. IAM auth on, storage encrypted, and the audit log driven from one variable because its two halves live in different resources and either alone logs nothing.
aws-dms
ssl_mode defaults to none in AWS, so a task reads your entire production database and writes it elsewhere unencrypted. This defaults to require, refuses none unless stated, and pushes the credential into Secrets Manager rather than state.
aws-quicksight
A QuickSight subscription on Enterprise edition through IAM Identity Center, with admin, author and reader groups, termination protection on because unsubscribing deletes every dashboard, and a VPC connection with its own role so a private database stays private. The authentication method is permanent; Standard edition and QuickSight-managed users are accepted by name.
aws-opensearch-serverless
A collection cannot exist without an encryption policy and the quickest one uses the AWS-owned key; the network policy decides whether the endpoint answers on the internet; without a data access policy nobody can read or write, with a wide one everyone can; indexes grow until a policy expires them. Private through VPC endpoints (public by name), your key when given, principals named.
