The feature that enhances security for application access is Identity and Access Management (IAM). IAM provides a robust framework for controlling user identities and assigning permissions within Alibaba Cloud. Through IAM, organizations can create and manage user accounts, define roles, and establish permissions governing access to different resources, ensuring that only authorized users can access sensitive applications and data.

This centralized management of access control supports a principle of least privilege, which is essential for minimizing security risks by restricting user access to only those resources necessary for their roles. IAM functionalities include user authentication, role-based access control, and policies that define what actions users can perform on specified resources, promoting a secure environment for application access.

In contrast, while the other features like Container Registry, File Storage Service, and Server Load Balancer serve important functions in application deployment and resource management, they do not specifically focus on enhancing security for application access. Container Registry manages Docker images, File Storage Service provides scalable file storage, and Server Load Balancer helps distribute incoming traffic across multiple servers. These services contribute to the overall performance and scalability of applications, but they do not provide the same level of access control and security management as IAM.
