Descriptionโ
Descriptionโ
Real-time monitoring of API calls can be achieved by directing CloudTrail Logs to CloudWatch Logs, or an external Security information and event management (SIEM) environment, and establishing corresponding metric filters and alarms.
It is recommended that a metric filter and alarm be established for customer created CMKs which have changed state to disabled or scheduled deletion.
Rationaleโ
CloudWatch is an AWS native service that allows you to observe and monitor resources and applications. CloudTrail Logs can also be sent to an external Security information and event management (SIEM) environment for monitoring and alerting.
Data encrypted with disabled or deleted keys will no longer be accessible. Changes in the state of a CMK should be monitored to make sure the change is intentional.
Impactโ
Creation, storage, and management of CMK may create additional labor requirements compared to the use of Provide Managed Keys.
Auditโ
If you are using CloudTrails and CloudWatch, perform the following to ensure that there is at least one active multi-region CloudTrail with prescribed metric filters and alarms configured:

Remediationโ
Remediationโ
If you are using CloudTrails and CloudWatch, perform the following to setup the metric filter, alarm, SNS topic, and subscription:
- Create a metric filter based on filter pattern provided which checks for disabled or scheduled for deletion CMK's and the
<cloudtrail_log_group_name>taken from audit step 1:aws logs put-metric-filter --log-group-name <cloudtrail_log_group_name> --filter-name <disable_or_delete_cmk_changes_metric> --metric-transformations metricName=<disable_or_delete_cmk_changes_metric>,metricNamespace='CISBenchmark', metricValue=1 --filter-pattern '{($.eventSource = kms.amazonaws.com) && (($.eventName=DisableKey)||($.eventName=ScheduleKeyDeletion)) }'Note: You can choose your own metricName and metricNamespace strings. Using the same metricNamespace for all Foundations Benchmark metrics will group them together.
- Create an SNS topic that the alarm will notify:
aws sns create-topic --name <sns_topic_name>Note: you can execute this command once and then re-use the same topic for all monitoring alarms.
