What action should be taken if a developer requires full access to production data?

Implementing a temporary access policy is a prudent action when a developer requires full access to production data. This approach allows for necessary access to be granted while minimizing the risk associated with having full access to sensitive data. By establishing a temporary access policy, organizations can better control when and how developers access production data, ensuring that access is limited to the duration needed for specific tasks or projects.

This method supports the principle of least privilege, ensuring that users have the minimal access necessary to perform their work without leaving them permanently exposed to potential risks. Additionally, it allows for oversight and accountability, as access can be revoked after the task is complete, reducing the window of vulnerability.

In contrast, providing full access at all times poses significant security risks, as it could lead to unauthorized disclosure or alteration of production data. Relying solely on segregation of duties doesn't address the developer's need for access in a controlled manner. Monitoring developer activities closely is beneficial but does not address the root issue of excessive access rights. Thus, implementing a temporary access policy strikes a balanced approach in managing security and operational needs effectively.
