This rule detects when a GSuite user has disabled their two-step verification (2SV) setting. Two-step verification is a critical security mechanism designed to provide an additional layer of protection over a user's account beyond just the password. When a user disables this feature, it increases the risk of unauthorized access to sensitive information and can potentially expose the account to various security threats. The rule utilizes logs from GSuite's ActivityEvent to identify when the 2SV is changed, specifically focusing on events where the verification has been disabled. If such an event is detected, it is categorized under Defense Evasion, as it modifies the authentication process that is intended to secure user access.
