Description
Identifies an attempt to Bypass conditional access rule(s) in Microsoft Entra ID. The ConditionalAccessStatus column value details if there was an attempt to bypass Conditional Access or if the Conditional access rule was not satisfied (ConditionalAccessStatus == 1).

Depending on your organization's configuration, some Conditional Access failures may be legitimate and expected. It is recommended to review alerts generated by this rule in the context of your organization's Conditional Access policies and adjust the detection threshold as needed to reduce false positives. This rule includes an optional filter that leverages a watchlist (ConditionalAccessBenignStatusCodes) to exclude known benign status codes. You can customize this watchlist with status codes that are expected in your environment and do not indicate malicious activity. By default, the watchlist-based filtering is commented out to provide full visibility into all relevant events. You may choose to enable this filter by uncommenting the corresponding line in the query to reduce noise from known benign scenarios.
