Azure AD Connect

The Azure Active Directory Connect or Azure AD Connect tool, which was once known as Windows Azure Active Directory Synchronization or DirSync, is an officially recommended directory synchronization tool for Microsoft 365. It is built up of three parts viz. the synchronization services, the optional Active Directory Federation Services piece, and the monitoring piece done with the help of Azure AD Connect health. It can easily operate as a software-based tool that after configuring once can run automatically in the background without any user interaction. 

Using Azure AD Connect for Directory Synchronization

If you are using Azure AD Connect for Directory Synchronization:
  • Although new user group, and contact devices in an on-premises Active Directory are added to Microsoft 365, but the licenses are not assigned to these objects automatically.

  • The modified on-premises AD attributes of existing user, group, and contact objects are also modified in Microsoft 365 but not all of them can be synchronized to Microsoft 365.

  • The deleted on-premises AD's existing user, group, and contact objects are also deleted from Microsoft 365.

  • Similarly, the disabled on-premises existing user objects are also disabled in Microsoft 365 without any automatic unassigned licenses.  

Azure AD Connect also supports the following scenarios:

  1. Multiple Active Directory forest environments
  2. Multiple exchange organizations to one Microsoft 365 tenant

There are two things required to be understood:

  1. The source of authority is on the on-premises AD.
  2. You are mastering objects from within your on-premises AD with the help of whatever management tools being used today, like AD Users and Computers or Windows PowerShell. 

Azure AD Connect Cloud Provisioning

It is a new Microsoft agent designed to meet and accomplish your hybrid identity goals for synchronization of users, groups, and contacts to Azure AD. You can use it along with Azure AD Connect sync and get different benefits:
  • Support for synchronizing to an Azure AD tenant from a multi-forest disconnected AD forest environment- commonly, scenarios include merger and acquisition in which the acquired one's AD forests are isolated from the parent company's AD forests and companies having history contains multiple AD forests.

  • Easy installation with light-weight provisioning agents- the agents acts as a bridge from AD to Azure AD with all the sync configuration managed in the cloud. 

  • Multiple provisioning agents helps to simplify high availability deployments, particularly critical for the organization dependent on password hash synchronization from AD to Azure AD.

An organization only have to deploy a lightweight agent acting as a bridge between Azure AD and AD, in their on-premises and IaaS-hosted environment.

  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

Work with String Data Using KQL Statements

  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
