Description:
Reports on the Microsoft Secure Score improvement action Quarantine messages that are detected from impersonated users, part of Microsoft Defender for Office 365. Microsoft evaluates this control across your tenant's policies and Augmentt surfaces the result alongside your other posture checks.
Why:
This setting specifies the action to take on detected user impersonation messages.
If a message is detected from an impersonated user, no default action will be taken. We recommend quarantining the message.
Configured: 100% of users are affected by policies that are configured securely
Not Configured: One or more applicable policies are not configured securely.
Scoring: Contributes up to 1 point to the Posture Recommendations score.
