Description#
You can do real-time monitoring of API calls by directing CloudTrail logs to CloudWatch Logs and establishing corresponding metric filters and alarms.
Security groups are a stateful packet filter that controls ingress and egress traffic in a VPC.
CIS recommends that you create a metric filter and alarm for changes to security groups. Monitoring these changes helps ensure that resources and services aren’t unintentionally exposed.
Resolution#
Create an alarm to alert on security group changes
