Account/Authentication - Azure Active Directory - Ensure Security Defaults is Disabled on Azure AD

By Ashwin Venugopal -

 






Summary

Security Defaults easily secure and protect your organization and consists of preconfigured security settings for common attacks.

In order to ensure that all the organizations have a basic level of security-enabled at no extra cost, Microsoft is making security defaults available to everyone that can be turned on in the Azure portal.

However, their use will prohibit custom settings which are being set with more advanced settings from this benchmark.

Reason

Security Defaults offer secure default settings that can be managed on behalf of the organizations to keep customers safe until they are ready to manage their own identity security settings.

For example doing the following:

  • Requiring all users and admins to register for MFA.
  • Challenging users with MFA - mostly when they show up on a new device or app, but more often for critical roles and tasks.
  • Disabling authentication from legacy authentication clients, which can't do MFA.

What If?

Disabling of security defaults can affect your environment depending upon security controls implemented in the environment. However, most organizations implements equivalent controls to replace Security Defaults.

It may be necessary to check settings in other Microsoft products, like Azure, to ensure settings and functionality are as expected when disabling security defaults for MS365.

How to?

To disable security defaults in your directory:
  1. Sign-in to Azure portal as security administrator, Conditional Access administrator, or global administrator.
  2. Now, browse to Azure Active Directory > properties.
  3. Select Manage security defaults.
  4.  After that, set the Enable security defaults toggle to No.
  5. Finally, Save.

Monitor:

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
