The "Azure AD MFA Disabled" detection focuses on identifying instances where Multi-Factor Authentication (MFA) is disabled for user accounts in Azure Active Directory (Azure AD). MFA is a critical security measure that adds an additional layer of protection beyond just passwords. Disabling MFA can significantly weaken account security, making it easier for attackers to gain unauthorized access.
Scenario 1: An attacker gains access to a compromised administrative account in Azure AD and disables MFA for multiple user accounts to facilitate further unauthorized access. This detection is triggered by the sudden change in MFA settings.
Scenario 2: During a scheduled security assessment, the penetration testing team disables MFA for specific test accounts to evaluate the organization's detection and response capabilities. The detection is triggered, and the activity is verified as part of the assessment.
If this detection indicates a genuine threat, the organization faces significant risks:
Easier unauthorized access to user accounts without the additional layer of MFA protection. Attackers can gain further access to sensitive resources and escalate their privileges within the network.
Increased risk of unauthorized access to sensitive data and critical systems. Potential for attackers to disrupt services and operations.
Non-compliance with security policies and regulations that mandate the use of MFA.
