This detection rule identifies instances when Multi-Factor Authentication (MFA) is disabled within Google Workspace, which can expose accounts to unauthorized access risks. The rule tracks specific events related to the enforcement of security settings — notably 'ENFORCE_STRONG_AUTHENTICATION' and 'ALLOW_STRONG_AUTHENTICATION' — and checks for changes indicated by setting the 'new_value' field to false. By monitoring these events, security professionals can quickly react to changes in authentication settings that may compromise account security. The significance of this rule lies in its ability to highlight possibly risky configurations, prompting investigation and remediation if necessary. Although there are legitimate reasons for MFA to be disabled (e.g., administrator actions), those cases should be carefully reviewed to mitigate potential security threats.
