AWS CloudFormation Misconfiguration: Missing CloudTrail Log Validation

JSON
YAML

Abstract

The template defines a trail without log file validation.

Explanation

By default, CloudTrail log file validation is disabled, which prevents investigators from asserting that there has been no external tampering with CloudTrail log files.

A direct result of this is that an attacker with the necessary privileges can perform harmful configuration changes and cover their tracks by modifying CloudTrail logs.

Example 1: The following is an example of a trail with log file validation disabled by setting EnableLogFileValidation to false. Omitting the property results in the default value set to false as well.


"myTrail": {
    "DependsOn": [
        "BucketPolicy"
    ],
    "Type": "AWS::CloudTrail::Trail",
    "Properties": {
        "S3BucketName": {
            "Ref": "S3Bucket"
        },
        "IsLogging": true,
        "EnableLogFileValidation": false
    }
}
