Can you rely exclusively on sharing inheritance in a security setup?

In a security setup, sharing inheritance refers to a method in which permissions are passed down from parent objects to child objects. While it might seem appealing to rely exclusively on this method, it has its limitations.

The assertion that blocking all users not covered by sharing might ensure control of access can lead to significant security risks. This approach can create a false sense of security by assuming that all necessary access controls are being addressed solely through sharing settings. However, it does not account for situations where specific user permissions might be needed. Each organization typically has diverse data access requirements that go beyond what sharing inheritance can cover.

Therefore, a robust security setup requires careful consideration of specific permissions tailored to individual user needs or roles to ensure that the principle of least privilege is followed. Implementing explicit permissions allows for more nuanced control over access to resources, ensuring that only qualified individuals can access certain data or functionality.

In summary, while sharing inheritance is a useful component of a security model, relying on it exclusively can lead to vulnerabilities that might undermine the overall security posture of the system. It’s crucial to complement it with specific permissions to achieve a well-rounded and secure environment.
