What is one benefit of using Application Security Groups in Alibaba Cloud?

Using Application Security Groups (ASGs) in Alibaba Cloud allows for effective management of network traffic based on defined security policies. ASGs enable users to logically group resources, such as Elastic Compute Service (ECS) instances, and apply security rules that facilitate controlled communication among these resources. This means that you can specify which applications can interact with each other within the same security group, thus providing a robust mechanism for enhancing the security posture of your applications by limiting exposure and minimizing the attack surface.

With ASGs, administrators can easily implement rules that dictate which inbound and outbound traffic is permitted, enhancing the overall security through easier policy management without the need to configure security rules for each individual resource. This capability streamlines operations by allowing security policies to be applied at the group level, ultimately leading to more efficient management of network security in cloud environments.

In contrast to the other choices, which emphasize either limited functionality or incorrect purpose, the ability to manage network traffic is a core strength of Application Security Groups, making them an essential feature for establishing effective security measures within Oracle Cloud.
