Description
Remediation
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 failed console authentication attempts.
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 failed console logins may decrease the lead time to detect an attempt to brute-force a credential, which may provide an indicator, such as the source IP address, that can be used in other event correlations.
Impact
Monitoring for these failures may create a large number of alerts, more so in larger environments.
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 AWS management Console Login Failures 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 <console_signin_failure_metric> --metric-transformations metricName=<console_signin_failure_metric>, metricNamespace='CISBenchmark', metricValue=1 --filter-pattern '{ ($.eventName = ConsoleLogin) && ($.errorMessage = "Failed authentication") }'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.
