Service	cloudwatch

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 console logins that aren't protected by MFA. Monitoring for single-factor console logins increases visibility into accounts that aren't protected by MFA.

Resolution

Create an alarm to alert on non MFA logins
