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 for console logins that are not protected by multi-factor authentication (MFA).

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 for single-factor console logins will increase visibility into accounts that are not protected by MFA. These type of accounts are more susceptible to compromise and unauthorized access.

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​

If you are using CloudTrails and CloudWatch, perform the following to setup the metric filter, alarm, SNS topic, and subscription:

  1. Create a metric filter based on filter pattern provided which checks for AWS Management Console sign-in without MFA and the <cloudtrail_log_group_name> taken from audit step 1.

Use Command:

aws logs put-metric-filter --log-group-name <cloudtrail_log_group_name> --filter-name <no_mfa_console_signin_metric> --metric-transformations metricName=<no_mfa_console_signin_metric>,metricNamespace='CISBenchmark', metricValue=1 --filter-pattern '{ ($.eventName = "ConsoleLogin") && ($.additionalEventData.MFAUsed != "Yes") }'

Or (To reduce false positives incase Single Sign-On (SSO) is used in organization):

aws logs put-metric-filter --log-group-name <cloudtrail_log_group_name> --filter-name <no_mfa_console_signin_metric> --metric-transformations metricName=<no_mfa_console_signin_metric>, metricNamespace='CISBenchmark', metricValue=1 --filter-pattern '{ ($.eventName = "ConsoleLogin") && ($.additionalEventData.MFAUsed != "Yes") && ($.userIdentity.type = "IAMUser") && ($.responseElements.ConsoleLogin = "Success") }'
