Live-tested

Really deployed to a cloud sandbox, verified against its outputs and assertions, then destroyed - with the teardown confirmed.

Conformance

  • Static validation (fmt · validate · tflint)
  • Security scan clean (Checkov)
  • Plan test superseded by live test

Documentation

aws-sns

SNS standard or FIFO topic, encrypted at rest by default, with a TLS-only least-privilege topic policy and typed SQS / Lambda / HTTPS / email subscriptions. Works with Terraform and OpenTofu (>= 1.6), AWS provider >= 6.0, < 7.0. FIFO naming (.fifo suffix) is automatic, and message signing defaults to SHA-256 (signature version 2).

Status: static-validated, live-test pending. Ships under live-test quarantine — validated with tofu fmt, tofu validate, and tflint. Real apply → publish → destroy against an AWS account is pending a cloud sandbox. Live testing will restrict subscriptions to SQS/Lambda endpoints, which auto-confirm; email/SMS/HTTP confirmations cannot be completed in automation.

What you get:

  • aws_sns_topic — standard or FIFO, always SSE-encrypted.
  • aws_sns_topic_policy — a generated TLS-only, allow-listed policy (override with a full policy JSON string if you need to).
  • aws_sns_topic_subscription — a typed map of subscriptions with filter policies and per-subscription redrive (DLQ) support.

Secure defaults

  • Encryption at rest always on: defaults to the AWS-managed alias/aws/sns key; pass a CMK via kms_master_key_id for full key control.
  • TLS-only topic policy: denies any sns:Publish/sns:Subscribe made over a non-TLS connection (aws:SecureTransport = false). The account owner keeps management rights; IAM publishers and AWS service publishers are allow-listed (services pinned to their aws:SourceArn), and cross-account subscribe is off unless you name accounts in subscriber_account_ids.
  • SHA-256 signing (signature_version = 2) by default.
  • Subscriptions support redrive to a DLQ so failed deliveries are not lost; use raw_message_delivery = true for SQS/HTTPS when you do not want the SNS envelope.
