Is it possible to prevent certain security group rules account/org wide?

Question

i.e. say I want to prevent 0.0.0.0/0 or some arbitrary IP from ever being applied as a security group rule, is it possible to do this from a an organization/account wide control approach?

Accepted Answer

There is no condition on a IAM statement where you can reference the destination of an ingress rule. You can do a DETECTIVE control via AWS Config as Chris_G said in the comment. See:How to auto-remediate internet accessible ports with AWS Config and AWS Systems Manager

Maybe another way to approach this, depending on what you are trying to achieve, is to create a SCP that denies the CreateInternetGateway and AttachInternetGateway EC2 operations.
