Description

This check verifies whether an Amazon CloudTrail resource is configured to send logs to an SNS topic by setting the sns_topic_name attribute. Without specifying sns_topic_name, CloudTrail will not publish notifications of log file delivery events to Amazon SNS, which could result in missed alerts or delayed incident response. To address this, you should configure CloudTrail with an SNS topic, as shown below:

resource "aws_cloudtrail" "example" {
  // ... other configuration ...
  sns_topic_name = "some-topic"
}

Compliant Code Examples

resource "aws_cloudtrail" "negative1" {
  # ... other configuration ...

  sns_topic_name = "some-topic"
}

Non-Compliant Code Examples

resource "aws_cloudtrail" "positive1" {
  # ... other configuration ...
}

resource "aws_cloudtrail" "positive2" {
  # ... other configuration ...

  sns_topic_name = null
}
