Description
Description
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 changes made to Identity and Access Management (IAM) policies.
Rationale
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.
Monitoring changes to IAM policies will help ensure authentication and authorization controls remain intact.
Impact
Monitoring these changes may cause a number of "false positives" more so in larger environments. This alert may need more tuning then others to eliminate some of those erroneous alerts.
Audit
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:

Remediation
Remediation
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 IAM policy changes 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 `<iam_changes_metric>` --metric-transformations metricName= `<iam_changes_metric>` ,metricNamespace='CISBenchmark',metricValue=1 --filter-pattern '{($.eventName=DeleteGroupPolicy)||($.eventName=DeleteRolePolicy)||($.eventName=DeleteUserPolicy)||($.eventName=PutGroupPolicy)||($.eventName=PutRolePolicy)||($.eventName=PutUserPolicy)||($.eventName=CreatePolicy)||($.eventName=DeletePolicy)||($.eventName=CreatePolicyVersion)||($.eventName=DeletePolicyVersion)||($.eventName=AttachRolePolicy)||($.eventName=DetachRolePolicy)||($.eventName=AttachUserPolicy)||($.eventName=DetachUserPolicy)||($.eventName=AttachGroupPolicy)||($.eventName=DetachGroupPolicy)}'
