Query: VPC security groups should restrict ingress CIFS access from 0.0.0.0/0 and ::/0

Description

Common Internet File System (CIFS) is a network file-sharing protocol that allows systems to share files over a network. However, unrestricted CIFS access can expose your data to unauthorized users, leading to potential security risks. It is important to restrict CIFS access to only trusted networks and users to prevent unauthorized access and data breaches.
