In what situations would you choose to implement an ACL-based security system instead of other access control models?

An ACL-based security system is preferred in situations where granular control over user permissions is required, such as when managing access to specific resources or actions within an application. This model excels in environments with diverse user roles and complex permission requirements, allowing for efficient management of individual rights without the need for extensive role hierarchies.

Additionally, ACLs are beneficial when dealing with third-party integrations or external users, as they provide a clear and concise way to manage their access without compromising internal security policies. They also offer flexibility in adapting to changing business needs, as new resources can be easily added or removed from the list without affecting overall system architecture.

In contrast, other access control models like Role-Based Access Control (RBAC) may not provide the same level of granularity and adaptability, making them less suitable for certain scenarios where fine-tuned permission management is crucial.
