CloudTrail with a Hardened Evidence Bucket
Multi-region trail with log file validation always on, a bucket that blocks public access, versions, encrypts and denies non-TLS, a policy pinned to this trail, optional CloudWatch delivery and opt-in data events.
Verification

Documentation
aws-cloudtrail
CloudTrail with a hardened destination bucket, log file validation, optional
KMS encryption, optional CloudWatch Logs delivery and opt-in data events. Works
with Terraform and OpenTofu (>= 1.6), AWS provider >= 6.0, < 7.0.
Secure defaults:
- Log file validation is always on and has no switch. Without it CloudTrail writes objects and nothing proves they are the ones it wrote; the digest files are what let you demonstrate a gap or a modification afterwards
- Multi-region by default: a single-region trail records nothing about the regions an attacker gets to choose instead
- The bucket blocks public access, versions objects, encrypts at rest, denies
non-TLS access, and is not
force_destroy- an audit trail that the same mistake can delete is not an audit trail - The bucket policy pins
aws:SourceArnto this trail, so another account that knows the bucket name cannot write into it - Data events are opt-in and validated: they bill per event, and S3 object reads on a busy bucket can dwarf the management events
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-config
Recorder, delivery channel, service role and managed rules. Starting the recorder is a separate resource people leave out, so a stopped recorder looks identical to a running one until an investigation finds an empty timeline.
aws-grafana
account_access_type ORGANIZATION lets a workspace query observability data in accounts whose owners never approved it, and SERVICE_MANAGED means AWS wrote those data-source policies. Current account, a role you wrote, and an endpoint narrowed to a prefix list rather than the whole internet.
aws-prometheus
Alerting needs BOTH an alert manager definition and a rule group namespace; with either missing the workspace stores metrics and raises nothing while every dashboard reports it healthy. Without logging_configuration a throttled remote_write likewise produces no metrics, no error and no alert.
aws-cloudtrail-lake
A CloudTrail Lake event data store with the retention decided rather than inherited. The aws provider defaults retention to 2555 days; on the default pricing option AWS includes 366 and bills the rest, so the provider default quietly buys 2,189 days of storage. This module defaults to 366, prints the billed days, and keeps termination protection on.
aws-cloudwatch
A self-contained CloudWatch observability bundle - an encrypted log group with retention, a metric alarm, and a dashboard - that stands up from just a name and points at any real metric.
aws-vpc-flow-logs
Flow logs for an existing VPC in the extended format an investigation needs (flow direction, TCP flags, packet addresses through NAT), at one minute rather than ten, all traffic rather than rejects, to a CloudWatch log group created with retention and your KMS key, or to S3 as Hive-partitioned Parquet when a bucket is given. Partial traffic and the AWS-managed key are accepted by name.
