Securing Microsoft Entra ID Applications: Addressing the Threat  of Misconfigured Permissions

Misconfigured app permissions in Microsoft Entra ID pose a significant security risk, enabling attackers to exploit applications with excessive or improperly assigned privileges. This session will delve into the vulnerabilities associated with misconfigurations, such as assigning non-administrative accounts as application owners and granting unconstrained permissions like Mail.ReadWrite or Mail.Send. 

Participants will explore real-world examples, including the Midnight Blizzard attack, which exploited a compromised OAuth application to infiltrate Microsoft’s tenant. 

Attendees will learn actionable strategies to mitigate these threats, including:

• Implementing stringent access controls for app ownership.
• Applying the principle of least privilege to app permissions.
• Utilizing tools such as PowerShell cmdlets and security scanners to enforce application access policies and monitor elevated permissions.

Join us to gain critical insights into securing your Entra ID environment by addressing common misconfigurations and ensuring robust permission management.
