Planning a Microsoft Sentinel workspace is a crucial task for anyone preparing for the SC-200 Microsoft Security Operations Analyst exam. Understanding how to effectively put together a workspace can provide you with the necessary skills to collect, analyze, and respond to security threats within your organization. Here, we guide you through the process while providing practical examples for added clarity.
Understanding Microsoft Sentinel Workspace
A Microsoft Sentinel workspace is fundamentally a container where your Azure Sentinel’s data resides. It contains logs, settings, queries, and more. Planning the workspace effectively allows you to make better use of Sentinel’s security analytics and threat intelligence capabilities.
Pre-requisites for the Workspace
Before creating your Sentinel workspace, some pre-requisites must be met:
- An active Azure subscription: You must have an Azure subscription to use Microsoft Sentinel.
- Permission requirements: You need to have the necessary predefined roles, such as Owner, Contributor, or Reader, and Azure Active Directory roles like Security Admin or Global Admin.
Steps in Planning a Sentinel Workspace
- Defining the workspace structure: This decision largely depends on your organization’s size and the complexity of your IT environment. You could opt for a centralized workspace for smaller companies. In contrast, larger organizations with complex and distributed IT infrastructure might need multiple workspaces.
- Selecting the data sources: Microsoft Sentinel supports a wide array of data sources for logs, such as Windows Event Logs, Azure Activity Logs, and Firewall Logs. Identify the logs relevant to your security operations.
- Data connectors setup: After identifying data sources, configure data connectors in Sentinel to pull the log files.
- Configuring data storage: Azure Sentinel uses Azure Log Analytics for storing log data. You’d therefore need to estimate storage costs and requirements depending on the data volume.
- Defining threat detection rules: Configure rules in Sentinel to spot threats or anomalies in the log data. You may use Microsoft’s built-in templates or customize your own.
- Incident response planning: Finally, plan for automated responses to threats detected by Sentinel using Azure Logic Apps. It could include sending email notifications or automatically mitigating the threats.
Example:
Here we’ll detail the steps for setting up a Sentinel workspace.
azure
# Login to your Azure account
az login
# Create a resource group
az group create --name MyResourceGroup --location eastus
# Create a workspace for Log Analytics
az monitor log-analytics workspace create --workspace-name MyWorkspace --resource-group MyResourceGroup
Following these guidelines to plan for a Microsoft Sentinel workspace ensures an efficient approach to security operations in an organization. It gives you the ability to actively detect threats in your environment and respond to them effectively, and it could be a critical capability for any Microsoft Security Operations Analyst or SC-200 aspirant.

Answer: True
Explanation: Administrators have all the necessary capabilities such as setting permissions, defining roles, or creating resources to plan a Microsoft Sentinel workspace.
Which of the following is required to ingest data to a Sentinel workspace?
- a) Azure subscription
- b) Azure Log Analytics workspace
- c) Either a or b
- d) Both a and b
Answer: d) Both a and b
Explanation: Both an Azure subscription and Azure Log Analytics workspace are required to ingest data into Microsoft Sentinel.
A workspace in Microsoft Sentinel can be connected with which other solution?

- b) SQL Database
- c) Both a and b
- d) Neither a nor b
Answer: a) Microsoft 365 security center
Explanation: In Microsoft Sentinel, you can connect Microsoft 365 security center, or any other data source, to a workspace for better management and synchronization.
True or False: When planning a Microsoft Sentinel workspace, we can define custom roles.
- True
- False
Answer: True
Explanation: In a Microsoft Sentinel workspace, roles and responsibilities can be customized to cater to the needs of your organization.
Once you enable Azure Sentinel, the cost is calculated based on what?
- a) The number of users
- b) The amount of ingested data
- c) The number of devices connected
- d) The period of using Azure Sentinel
Answer: b) The amount of ingested data
Explanation: The cost for Azure Sentinel is primarily based on the amount of data ingested.
The Microsoft Sentinel workspace cannot be used to cover which of the following elements?
- a) Security events
- b) Application logs
- c) Directory data
- d) Human resources data
Answer: d) Human resources data
Explanation: The primary focus of Microsoft Sentinel is cyber security. Therefore, it does not cover human resources data but focuses on other technical aspects, such as application logs or security events.
Microsoft Sentinel cannot connect to which of the following for data collection?
- a) Azure Active Directory
- b) Office 365
- c) Azure Storage Account
- d) Microsoft Teams
Answer: d) Microsoft Teams
Explanation: While Microsoft Sentinel can connect to a variety of data sources, as of now, it does not have a built-in connector specifically for Microsoft Teams.
