The rule 'Auth0 MFA Policy Disabled' is designed to detect instances when a user disables Multi-Factor Authentication (MFA) for an organization's Auth0 tenant. This rule focuses on monitoring the relevant API calls that change MFA settings. It is vital since disabling MFA can significantly decrease the security posture of an organization, exposing user accounts and sensitive data to potential compromise. The rule employs logging associated with Auth0's API endpoint to trace any modification in MFA policies and triggers an alert if the action is detected. The analysis includes examining both the expected and actual results of operations concerning changes in MFA settings, the user performing these operations, their roles, the IP address from which these actions were initiated, and timestamps to ensure accountability. Should MFA be disabled, the detected user must provide a valid business justification for this action, and configuration should be reverted promptly to maintain security integrity. The rule emphasizes the importance of vigilance and quick recovery to uphold organizational security standards.
