In a recent analysis by Tier Zero Security, researchers delve into Microsoft Entra Connect Sync & Cloud Sync, tools critical for syncing on-premises directories with Azure AD. Entra Connect Sync uses connectors to link on-premises AD with Azure AD for consistent user identities. The synchronization process involves import, sync, and export stages
Security measures like encryption and MFA are in place. Meanwhile, Entra Cloud Sync, managed by Microsoft, uses agents for syncing, prioritizes scalability, and offers robust security features like automatic updates. The study highlights potential vulnerabilities in both methods, such as data interception and tampering, emphasizing the need for strong security configurations. A possible attack vector involves exfiltrating passwords through vulnerable service accounts. The examination underscores the significance of secure synchronization configurations to thwart potential hacker exploitation. https://cybersecuritynews.com/microsoft-entra-connect-sync-cloud-sync/
