Plugin Title Overlapping Security Groups
Cloud AWS
Category EC2
Description Determine if EC2 instances have security groups that share the same rules
More Info Overlapping security group rules make managing EC2 instance access much more difficult. If a rule is removed from one security group, the access may still remain in another, resulting in unintended access to the instance.

Recommended Action Structure security groups to provide a single category of access and do not duplicate rules across groups used by the same instances.
