| 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. |
| AWS Link | http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/authorizing-access-to-an-instance.html |
| Recommended Action | Structure security groups to provide a single category of access and do not duplicate rules across groups used by the same instances. |
