What security aspect should be prioritized when offering vendor access to sensitive blobs in Azure?

Prioritizing time-limited access when offering vendor access to sensitive blobs in Azure is crucial for maintaining security and minimizing risk. Time-limited access ensures that vendors can only access the blobs for a predetermined period, reducing the likelihood of unauthorized access or data breaches after the access period has expired. This approach provides a controlled and audit-friendly way to manage access, enabling organizations to effectively monitor vendor activities and quickly revoke permissions when they are no longer needed.

While encryption of stored data is also an important security measure, it is more of a foundational control rather than a direct method of managing access. Public sharing of data and open access to accounts both increase the risk of exposing sensitive information and should be avoided in contexts where data privacy and integrity are a concern. Time-limited access strikes a balance between giving vendors the necessary access to perform their duties while reducing the window of opportunity for potential misuse.
