Getting Started with Microsoft Sentinel- Access Microsoft Sentinel

By Ashwin Venugopal -

 





Overview

Generally, users with an access to Microsoft Sentinel workspace, also have access to all the other data resources. However, there might be some users who require access to selective data only. Hence, it is recommended to configure role-based access control (RBAC), which is also known as setting up resource-context RBAC. 

Scenarios For Resource-Context RBAC

The following are the scenarios in which resource-context RBAC can be of most help:

Requirement Type

SOC Team

Non-SOC Team

Permissions

The entire workspace

Specific resources only

Data Access

All data in the workspace

Only data for resources that the team is authorized to access

Experience

The full Microsoft Sentinel experience, possibly limited by the functional permissions assigned to the user

Log queries and workbooks only

 Resource-context RBAC is a good solution for the similar access requirements to the non-SOC team.


Alternative Methods For Implementing Resource-Context RBAC

Resource-context RBAC might not offer a full solution. Hence, the following table lists the scenarios for other solutions for data access:

Scenario

Solution

A subsidiary has an SOC team that requires a full Microsoft Sentinel experience.

Here, a multi-workspace architecture to separate the data permissions.

Required o provide access to a special type of event.

In this case, table-level RBAC can be used to define permissions for each table.

Limit access to a more granular level, either not based on the resource, or to only a subset of the fields in an event,

Access can be offered to data via built-in integration with Power BI dashboards and reports.

 

Explicitly Configure Resource-Context RBAC

To explicitly configure resource-context RBAC:
  • Resource-context RBAC should be enabled in Azure monitor.
  • A resource group should be created for each users team, who requires access to some resources, not the entire Microsoft Sentinel environment. 
  • Now, resource can be assigned and events can be tagged with relevant resource IDs, to the created resource team groups

When the data is sent to Microsoft Sentinel, the log records are automatically tagged with the resource ID of the data source.

Query, Visualize, & Monitor Data in Azure Sentinel

  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. Templates section- You can access existing workbook templates on the Templates tab. You can save some of the workbooks for quick access and they will appear on the My Workbooks tab.  From the

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
