How can users enforce security policies across multiple accounts in Alibaba Cloud?

Enforcing security policies across multiple accounts in Alibaba Cloud can be effectively achieved through the use of Organizations and Resource Access Management (RAM) policies. The Organizations feature allows users to manage and organize multiple Alibaba Cloud accounts centrally. By creating an organization, users can define service control policies (SCPs) that apply to all accounts within the organization, ensuring consistent security boundaries.

Resource Access Management (RAM) complements this capability by enabling fine-grained access controls within each account. With RAM, users can specify permissions for different resources and actions at various levels, such as user, group, or role. This two-fold approach is vital for establishing a cohesive security posture across multiple accounts, allowing organizations to enforce compliance, manage risks, and safeguard critical data while maintaining oversight and control over all the accounts under their umbrella.

The other choices do not facilitate a centralized and scalable approach to enforce security policies across multiple accounts.
