What is a key method for preventing data leakage in Azure?

Implementing Azure Information Protection is a key method for preventing data leakage in Azure because it provides the capability to classify, label, and protect sensitive information based on its content and context. This service helps organizations safeguard their data by assigning protection policies that can include encryption, rights restrictions, and access controls. For example, with Azure Information Protection, users can easily apply labels to documents, which dictate the level of protection needed, and ensure that sensitive data is not improperly shared or accessed.

This focused approach allows organizations to maintain control over data, even when it is shared externally or across different platforms. Furthermore, it facilitates compliance with various regulatory requirements concerning data protection and privacy. By emphasizing the classification and protection of data, Azure Information Protection directly addresses the risk of data leakage, making it a robust solution for securing sensitive information.

In contrast, while enabling multi-factor authentication and regularly updating user passwords enhance security, they primarily focus on access control rather than the protection of the data itself. Using only on-premises resources does not necessarily enhance data security, as it can limit the utility and scalability of cloud services while not addressing the core challenge of preventing data leakage regardless of where data resides.
