Mobile Device Management - Ensure that Mobile Device Password Reuse Is Prohibited

By Ashwin Venugopal -

 






Summary

Users are not allowed to reuse the same password on their mobile devices.

Reason

Mobile devices without this protection are vulnerable to attackers who can steal account credentials, data, or install malware on the device. Unique and unused passwords should be chosen whenever a password is changed. This practice will lessen the probability of the password being guessed by the attacker.

What If?

This change will have a moderate 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. Now, select Create profile 
  4. Set a Name for the policy, choose the appropriate Platform and select Device restrictions.
  5. In the Password section, ensure that Prevent reuse of previous passwords is set to 5

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. Make sure that a profile exists for each Platform.
  4. Review the Device restrictions section under Password and verify that Prevent reuse of previous passwords is set to 5.

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...
