What should you recommend to audit all users accessing data in Azure Cosmos DB accounts?

To audit all users accessing data in Azure Cosmos DB accounts, enabling Microsoft Defender for Cosmos DB is the most appropriate recommendation. Microsoft Defender for Cosmos DB provides advanced threat protection specifically designed for Cosmos DB, and it includes capabilities for monitoring and auditing access to the database. This protection helps in identifying unusual patterns of behavior and potential security threats, ensuring that all access to user data is tracked and logged effectively.

This tool also offers built-in alerts and reports for suspicious activities, which can significantly enhance the security posture of your Azure Cosmos DB environment. It plays a critical role in auditing activities by allowing organizations to maintain compliance and detect unauthorized access or anomalies in user interactions with the database.

While Azure Monitor, Microsoft Defender for Identity, and Azure Security Center provide valuable monitoring and security capabilities, they are not specifically tailored to auditing user access within Azure Cosmos DB. Azure Monitor focuses on the overall monitoring of Azure resources, and while it can track certain metrics, it does not provide the detailed access auditing specific to Cosmos DB. Microsoft Defender for Identity is geared towards protecting on-premises environments and identity-related threats, not specifically for auditing access in cloud database services. Azure Security Center offers a broader scope for securing Azure resources, but it may not provide the same level of specialized insight and
