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.

  Azure Sentinel Workbooks Several ready for use templates are provided by the Azure Sentinel that can be used to create your own workbook and then modify them as needed for Contoso. Most of the data connectors it uses to ingest data come with their own workbooks, but better insight can be obtained by simply looking into the data that is being ingested by using tables and visualizations, including bar and pie charts. You can also make your own workbook easily by using this data from the beginning instead of using the predefined templates. Workbook Page You can easily access the workbook page from the Azure Sentinel from the navigation pane which consists of the: Workbook header- You can add a new workbook and review the saved workbooks as well as templates that are available on the workbook page.

The loaf balancer also offers an option of DirectServerReturn which if configured, can help in directing the traffic from the DBMS VM to the SAP application layer directly to the application layer without routing through the load balancer. But, if it isn't configured, then the return traffic to the SAP application layer is routed through the load balancer. You can also use Azure Load Balan

  Extract Data from Unstructured String Fields Unstructured string fields often contains the Security log data and requires parsing to extract data. There are multiple ways of pulling information from string fields in KQL and the two primary operators used are extract and parse.  Extract It gets a match for a regular expression from a text string. You can convert the extracted substring to the indicated type.  Arguments regex- A regular expression. captureGroup- A positive int constant indicating the capture group to extract. 0 stands for the entire match, 1 for the value matched by the first '('parenthesis')' in the regular expression, 2 or more for subsequent parenthesis.  text- A string to search. typeLiteral- An optional type literal. If provided, the extracted substring is converted to this type.  Returns If regex finds a match in text- the substring matched against the indicated capture group captureGroup, optionally converted to typeLiteral. If there's no mat
