View and manage risky users in Microsoft 365 Lighthouse

  • Άρθρο

Microsoft collects and analyzes trillions of user sign-in signals each day. These signals are used to help build good user sign-in behavior patterns and identify potential risky sign-in attempts. Microsoft Entra ID Protection uses these signals to review user sign-in attempts and take action if there's suspicious activity.

Microsoft 365 Lighthouse helps manage risks detected by Microsoft Entra ID Protection by providing a single view of risky users across all your managed tenants. You can quickly secure risky users by either resetting their password or blocking them from signing in to their Microsoft 365 account. You can also view insights to better understand a user's risk and determine next steps.

Microsoft Entra ID Protection identifies risks of many types, including:

  • Leaked credentials
  • Anonymous IP use
  • Atypical travel
  • Signing in from infected devices
  • Signing in from IP addresses with suspicious activity
  • Signing in from unfamiliar locations

Note

This page provides insights around data that is limited or unavailable due to insufficient licensing.

Before you begin

The following conditions must be met before users can appear in the risky users list:

Review detected risks and take action

In Microsoft Entra ID Protection, risk detections include any identified suspicious actions related to user accounts in Microsoft Entra ID.

  1. In the left navigation pane in Lighthouse, select Users > Risky users.

  2. On the Risky Users page, review the users in the list with a risk state of At risk.

  3. Select View risk detections to get detailed information about the risks detected for each user. For more information about risk types and detection, see What is risk?.

  4. For each user, assess the risk detections and select one of the following actions, as appropriate:

    • Reset password - change or reset the user password.

    • Block sign-in - prevent anyone from signing in as this user.

    • Confirm user compromised - set risk state to confirmed compromised.

    • Dismiss user risk - set risk state to dismissed.

Take action on multiple user accounts at once

To take action on multiple affected users at once:

  1. In the left navigation pane in Lighthouse, select Users > Risky users.

  2. On the Risky Users page, select the set of users you want to take action on.

  3. Choose one of the following actions to perform:

    • Reset password

    • Block sign-in

    • Confirm user compromised

    • Dismiss user risk

Note

If an organization you're managing has a Microsoft Entra ID P2 license, we recommend you enable User risk-based conditional access policies for that organization. For more information, see Conditional Access: User risk-based Conditional Access.
