Elastic low deprecated kql
Deprecated - AWS ElastiCache Security Group Created
Identifies when an ElastiCache security group has been created. Amazon EC2-Classic and ElastiCache CacheSecurityGroups have been retired. Modern ElastiCache deployments run in a VPC and use standard EC2 security groups instead. This rule should be retained only for historical log analysis on legacy CloudTrail data. We recommend relying on "AWS EC2 Security Group Configuration Change" rule for network-control changes impacting ElastiCache in VPC-based deployments.
Detection Logic
event.dataset:aws.cloudtrail and event.provider:elasticache.amazonaws.com and event.action:"Create Cache Security Group" and
event.outcome:successFalse Positives
- ⚠ A ElastiCache security group may be created by a system or network administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. Security group creations by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
