With AWS PrivateLink, the marketing team can create an endpoint service to share theirinternal application with other accounts securely using private IP addresses. They can grant permission to specific AWS accounts to connect to the service and create interface VPC endpoints in the other accounts to access the application by using private IP addresses. This option does not require any changes to the network of the other business units, and it does not require peering or NATing. This solution is both scalable and secure.

To connect VPC resources over a transit Virtual Interface (VIF) using a Direct Connect connection, the company should advertise the on-premises network prefixes over the transit VIF and advertise the VPC prefixes from the Direct Connect gateway to the on-premises network over the same VIF. This configuration ensures seamless connectivity between the on-premises infrastructure and the AWS VPCs through the transit gateway, facilitating efficient and secure communication across the network.

AWS Documentation on AWS Direct Connect and transit gateways provides detailed instructions on configuring transit VIFs and routing for Direct Connect connections. This setup is recommended in AWS best practices for establishing dedicated network connections between on-premises environments and AWS to achieve low-latency, high-throughput, and secure connectivity.

This solution will meet the requirement with the least operational overhead because it directly denies the creation of the security group inbound rule with 0.0.0.0/0 as the source, which is the exact requirement. Additionally, it does not require any additional steps or resources such as invoking a Lambda function or adding a Config rule.

An SCP (Service Control Policy) is a policy that you can use to set fine-grained permissions for your AWS accounts within your organization. You can use SCPs to set permissions for the root user of an account and to delegate permissions to IAM users and roles in the accounts. You can use SCPs to set permissions that allow or deny access to specific services, actions, and resources.

To implement this solution, you would need to create an SCP that denies the ec2:AuthorizeSecurityGroupIngress action when the value of the aws:SourceIp condition key is 0.0.0.0/0. This SCP would then be applied to the NonProd OU. This would ensure that any security group inbound rule that includes 0.0.0.0/0 as the source will be denied, thus meeting the requirement.
