Description#

You can do real-time monitoring of API calls by directing CloudTrail logs to CloudWatch Logs and establishing corresponding metric filters and alarms.

CIS recommends that you create a metric filter and alarm for failed console authentication attempts. Monitoring failed console logins might decrease lead time to detect an attempt to brute-force a credential, which might provide an indicator, such as source IP, that you can use in other event correlations.

Resolution#

Create an alarm to alert on console login failures
