Case Study 2 - Litware Inc
Overview
Litware Inc. is a renewable company.
Litware has offices in Boston and Seattle. Litware also has remote users located across the United States. To access Litware resources, including cloud resources, the remote users establish a VPN connection to either office.
Existing Environment
Identity Environment
The network contains an Active Directory forest named litware.com that syncs to an Azure Active Directory (Azure AD) tenant named litware.com.
Microsoft 365 Environment
Litware has a Microsoft 365 E5 subscription linked to the litware.com Azure AD tenant. Microsoft Defender for Endpoint is deployed to all computers that run Windows 10. All Microsoft Cloud App Security built-in anomaly detection policies are enabled.
Azure Environment
Litware has an Azure subscription linked to the litware.com Azure AD tenant. The subscription contains resources in the East US Azure region as shown in the following table.

Network Environment
Each Litware office connects directly to the internet and has a site-to-site VPN connection to the virtual networks in the Azure subscription.
On-premises Environment
The on-premises network contains the computers shown in the following table.

Current problems
Cloud App Security frequently generates false positive alerts when users connect to both offices simultaneously.
Planned Changes
Litware plans to implement the following changes:
* Create and configure Azure Sentinel in the Azure subscription.
* Validate Azure Sentinel functionality by using Azure AD test user accounts.
Business Requirements
Litware identifies the following business requirements:
* The principle of least privilege must be used whenever possible.
* Costs must be minimized, as long as all other requirements are met.
* Logs collected by Log Analytics must provide a full audit trail of user activities.
* All domain controllers must be protected by using Microsoft Defender for Identity.
Azure Information Protection Requirements
All files that have security labels and are stored on the Windows 10 computers must be available from the Azure Information Protection - Data discovery dashboard.
Microsoft Defender for Endpoint requirements
All Cloud App Security unsanctioned apps must be blocked on the Windows 10 computers by using Microsoft Defender for Endpoint.
Microsoft Cloud App Security requirements
Cloud App Security must identify whether a user connection is anomalous based on tenant-level data.
Azure Defender Requirements
All servers must send logs to the same Log Analytics workspace.
Azure Sentinel Requirements
Litware must meet the following Azure Sentinel requirements:
* Integrate Azure Sentinel and Cloud App Security.
* Ensure that a user named admin1 can configure Azure Sentinel playbooks.
* Create an Azure Sentinel analytics rule based on a custom query. The rule must automatically initiate the execution of a playbook.
* Add notes to events that represent data access from a specific IP address to provide the ability to reference the IP address when navigating through an investigation graph while hunting.
* Create a test rule that generates alerts when inbound access to Microsoft Office 365 by the Azure AD test user accounts is detected. Alerts generated by the rule must be grouped into individual incidents, with one incident per test user account.
You need to restrict cloud apps running on CLIENT1 to meet the Microsoft Defender for Endpoint requirements.
Which two configurations should you modify? Each correct answer present part of the solution.
NOTE: Each correct selection is worth one point.

Your company uses Microsoft Sentinel to manage alerts from more than 10,000 IoT devices.
A security manager at the company reports that tracking security threats is increasingly difficult due to the large number of incidents.
You need to recommend a solution to provide a custom visualization to simplify the investigation of threats and to infer threats by using machine learning.
What should you include in the recommendation?

You have a Microsoft 365 E5 subscription that uses Microsoft Defender XDR.
You have a custom detection rule named Rule1 that generates an alert if more than five antivirus detections are identified on a device. Rule1 has a lookback period of 12 hours.
You need to change the lookback period to 48 hours.
What should you modify for Rule1?

Case Study 1 - Contoso Ltd
Overview
A company named Contoso Ltd. has a main office and five branch offices located throughout North America. The main office is in Seattle. The branch offices are in Toronto, Miami, Houston, Los Angeles, and Vancouver.
Contoso has a subsidiary named Fabrikam, Ltd. that has offices in New York and San Francisco.
Existing Environment
End-User Environment
All users at Contoso use Windows 10 devices. Each user is licensed for Microsoft 365. In addition, iOS devices are distributed to the members of the sales team at Contoso.
Cloud and Hybrid Infrastructure
All Contoso applications are deployed to Azure.
You enable Microsoft Cloud App Security.
Contoso and Fabrikam have different Azure Active Directory (Azure AD) tenants. Fabrikam recently purchased an Azure subscription and enabled Azure Defender for all supported resource types.
Current Problems
The security team at Contoso receives a large number of cybersecurity alerts. The security team spends too much time identifying which cybersecurity alerts are legitimate threats, and which are not.
The Contoso sales team uses only iOS devices. The sales team members exchange files with customers by using a variety of third-party tools. In the past, the sales team experienced various attacks on their devices.
The marketing team at Contoso has several Microsoft SharePoint Online sites for collaborating with external vendors. The marketing team has had several incidents in which vendors uploaded files that contain malware.
The executive team at Contoso suspects a security breach. The executive team requests that you identify which files had more than five activities during the past 48 hours, including data access, download, or deletion for Microsoft Cloud App Security-protected applications.
Requirements
Planned Changes
Contoso plans to integrate the security operations of both companies and manage all security operations centrally.
Technical Requirements
Contoso identifies the following technical requirements:
* Receive alerts if an Azure virtual machine is under brute force attack.
* Use Azure Sentinel to reduce organizational risk by rapidly remediating active attacks on the environment.
* Implement Azure Sentinel queries that correlate data across the Azure AD tenants of Contoso and Fabrikam.
* Develop a procedure to remediate Azure Defender for Key Vault alerts for Fabrikam in case of external attackers and a potential compromise of its own Azure AD applications.
* Identify all cases of users who failed to sign in to an Azure resource for the first time from a given country. A junior security administrator provides you with the following incomplete query.

| where ________ == True
Hotspot Question
You need to implement Azure Sentinel queries for Contoso and Fabrikam to meet the technical requirements.
What should you include in the solution? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

You have a custom analytics rule to detect threats in Azure Sentinel.
You discover that the analytics rule stopped running. The rule was disabled, and the rule name has a prefix of AUTO DISABLED.
What is a possible cause of the issue?
