Plugin Title Excessive Security Groups
Cloud AWS
Category EC2
Description Determine if there are an excessive number of security groups in the account
More Info Keeping the number of security groups to a minimum helps reduce the attack surface of an account. Rather than creating new groups with the same rules for each project, common rules should be grouped under the same security groups. For example, instead of adding port 22 from a known IP to every group, create a single "SSH" security group which can be used on multiple instances.
