3.1 Ensure CloudTrail is enabled in all regions - ReadWriteType
Information
AWS CloudTrail is a web service that records AWS API calls for your account and delivers log files to you. The recorded information includes the identity of the API caller, the time of the API call, the source IP address of the API caller, the request parameters, and the response elements returned by the AWS service. CloudTrail provides a history of AWS API calls for an account, including API calls made via the Management Console, SDKs, command line tools, and higher-level AWS services (such as CloudFormation).Rationale:
The AWS API call history produced by CloudTrail enables security analysis, resource change tracking, and compliance auditing. Additionally,
ensuring that a multi-regions trail exists will ensure that unexpected activity occurring in otherwise unused regions is detected
ensuring that a multi-regions trail exists will ensure that Global Service Logging is enabled for a trail by default to capture recording of events generated on AWS global services
for a multi-regions trail, ensuring that management events configured for all type of Read/Writes ensures recording of management operations that are performed on all resources in an AWS account
Impact:
S3 lifecycle features can be used to manage the accumulation and management of logs over time. See the following AWS resource for more information on these features:
https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lifecycle-mgmt.html
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
