Mobile Device Management - Ensure Mobile Devices Are Set To Wipe On Multiple Sign-in Failures To Prevent Brute Force Compromise

By Ashwin Venugopal -

 








Summary

Require mobile devices to wipe on multiple sign-in failures.

Reason

Devices without this protection are generally vulnerable to being accessed physically by attackers who can then steal account credentials, data, or install malware on the device. 

What If?

This setting should not cause any noticeable impact, however, if a user mistypes their password multiple times and causes their device to wipe, then, it will have high user impact. 

How to?

To set mobile device management profiles, use the Microsoft 365 Admin Center:
  1. Under Admin Centers pick Endpoint Management.
  2. Select Devices and then under Policy select Configuration profiles
  3. Select Create Profile
  4. Set a Name for the policy, choose the appropriate Platform and select Device restrictions.
  5. In the Password section, make sure that Number of sign-in failures before wiping devices is set to 10.  

Monitor:

To verify mobile device management profiles, use the Microsoft 365 Admin Center:
  1. Under Admin Centers pick Endpoint Management.
  2. Select Devices and then under Policy select Configuration profiles
  3. Review the list of profiles. Ensure that a profile exists for each Platform.
  4. Review the Password section under Device restrictions and verify Number of sign-in failures before wiping devices is set to 10.

  To read part 1, please click  here To read part 2, please click  here Microsoft Monitoring Agent (MMA) MMA is used across multiple Microsoft solutions and has undergone a few name changes as its features and functionality have evolved. If it is being considered to be used, then following areas should be covered during a Microsoft Sentinel deployment project: Consider the timelines and the strategy for a migration to AMA (Azure Monitor Agent) before the MMA end-of-life.  Consider the central deployment and management methodology for MMA. Determine which endpoints are in scope for deployment as these affect the log ingestion volume significantly.  Azure Monitor Agent (AMA) Organizations with MMA as the main Microsoft Sentinel agent should start planning the migration to AMA as soon as possible to avoid a rushed migration. One of the main advantages of AMA is the ability to control the log collection policy centrally and apply different policies against different...

The templates can be used to activate/deploy schedule alerts, create customized dashboards, create automation playbooks and perform threat-hunting activities. Generally, once deployed, the resources created have to be adjusted to match the existing environment, configure local credentials, etc. Methods of deployment: Manual- Administrator can manually configures the Microsoft Sentinel resources with the help of Azure portal. Any manual process has the inherent risks of human operator error, lack of compliance with potential change control procedures, and u...
