DRAG DROP You have a Microsoft 365 subscription.
You need to recommend a security solution to monitor the following activities:
User accounts that were potentially compromised
Users performing bulk file downloads from Microsoft SharePoint Online
What should you include in the recommendation for each activity? To answer, drag the appropriate components to the correct activities. Each component may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Select and Place:

Answer:


Box 1: Azure Active Directory (Azure AD) Identity Protection
Risk detections in Azure AD Identity Protection include any identified suspicious actions related to user accounts in the directory. Risk detections (both user and sign-in linked) contribute to the overall user risk score that is found in the Risky Users report.
Identity Protection provides organizations access to powerful resources to see and respond quickly to these suspicious actions.
Note:
Premium sign-in risk detections include:
* Token Issuer Anomaly - This risk detection indicates the SAML token issuer for the associated SAML token is potentially compromised. The claims included in the token are unusual or match known attacker patterns.
* Suspicious inbox manipulation rules - This detection is discovered by Microsoft Defender for Cloud Apps. This detection profiles your environment and triggers alerts when suspicious rules that delete or move messages or folders are set on a user's inbox. This detection may indicate that the user's account is compromised, that messages are being intentionally hidden, and that the mailbox is being used to distribute spam or malware in your organization.
* Etc.
Incorrect:
Not: Microsoft 365 Defender for Cloud
Part of your incident investigation can include user accounts. You can see the details of user accounts identified in the alerts of an incident in the Microsoft 365
Defender portal from Incidents & alerts > incident > Users.
Box 2: Microsoft 365 Defender for App
Defender for Cloud apps detect mass download (data exfiltration) policy
Detect when a certain user accesses or downloads a massive number of files in a short period of time.

Question 3

HOTSPOT You open Microsoft Defender for Cloud as shown in the following exhibit.

Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.
NOTE: Each correct selection is worth one point.
Hot Area:

Answer:


Box 1: Azure Web Application Firewall (WAF)
Restrict unauthorized network access control: 1 resource out of 11 needs to be addresses.
Restrict unauthorized network access - Azure offers a suite of tools designed to ensure accesses across your network meet the highest security standards.
Use these recommendations to manage Defender for Cloud's adaptive network hardening settings, ensure you've configured Azure Private Link for all relevant
PaaS services, enable Azure Firewall on your virtual networks, and more.
Note: Azure Web Application Firewall (WAF) is an optional addition to Azure Application Gateway.
Azure WAF protects inbound traffic to the web workloads, and the Azure Firewall inspects inbound traffic for the other applications. The Azure Firewall will cover outbound flows from both workload types.
Incorrect:
Not network security groups (NSGs).
Box 2: Microsoft Defender for servers
Enable endpoint protection - Defender for Cloud checks your organization's endpoints for active threat detection and response solutions such as Microsoft
Defender for Endpoint or any of the major solutions shown in this list.
When an Endpoint Detection and Response (EDR) solution isn't found, you can use these recommendations to deploy Microsoft Defender for Endpoint (included as part of Microsoft Defender for servers).
Incorrect:
Not Microsoft Defender for Resource Manager:
Microsoft Defender for Resource Manager does not handle endpoint protection.
Microsoft Defender for Resource Manager automatically monitors the resource management operations in your organization, whether they're performed through the Azure portal, Azure REST APIs, Azure CLI, or other Azure programmatic clients. Defender for Cloud runs advanced security analytics to detect threats and alerts you about suspicious activity.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are designing a security strategy for providing access to Azure App Service web apps through an Azure Front Door instance.
You need to recommend a solution to ensure that the web apps only allow access through the Front Door instance.
Solution: You recommend access restrictions based on HTTP headers that have the Front Door ID.
Does this meet the goal?

  • A. Yes
  • B. No
Answer:

a

Restrict access to a specific Azure Front Door instance.
Traffic from Azure Front Door to your application originates from a well-known set of IP ranges defined in the AzureFrontDoor.Backend service tag. Using a service tag restriction rule, you can restrict traffic to only originate from Azure Front Door. To ensure traffic only originates from your specific instance, you will need to further filter the incoming requests based on the unique http header that Azure Front Door sends.

Scenario: Requirements. Security Requirements include:
Only members of a group named InfraSec must be allowed to configure network security groups (NSGs) and instances of Azure Firewall, WAF, and Front Door in
Sub1.
If the Azure built-in roles don't meet the specific needs of your organization, you can create your own custom roles. Just like built-in roles, you can assign custom roles to users, groups, and service principals at management group (in preview only), subscription, and resource group scopes.
Incorrect:
Not D: Management groups are useful when you have multiple subscriptions. This is not what is addressed in this question.
Scenario: Fabrikam has a single Azure subscription named Sub1.
Note: If your organization has many Azure subscriptions, you may need a way to efficiently manage access, policies, and compliance for those subscriptions.
Management groups provide a governance scope above subscriptions. You organize subscriptions into management groups the governance conditions you apply cascade by inheritance to all associated subscriptions.
Management groups give you enterprise-grade management at scale no matter what type of subscriptions you might have. However, all subscriptions within a single management group must trust the same Azure Active Directory (Azure AD) tenant.

Scenario: The Contoso developers must be prevented from viewing the data in a column named MedicalHistory in the ClaimDetails table.
Dynamic data masking (DDM) limits sensitive data exposure by masking it to non-privileged users. It can be used to greatly simplify the design and coding of security in your application.
Dynamic data masking helps prevent unauthorized access to sensitive data by enabling customers to specify how much sensitive data to reveal with minimal impact on the application layer. DDM can be configured on designated database fields to hide sensitive data in the result sets of queries. With DDM, the data in the database isn't changed. DDM is easy to use with existing applications, since masking rules are applied in the query results.
Incorrect:
Not B: Transparent Data Encryption (TDE) encrypts the entire database, not specific columns.

You are designing the encryption standards for data at rest for an Azure resource.
You need to provide recommendations to ensure that the data at rest is encrypted by using AES-256 keys. The solution must support rotating the encryption keys monthly.
Solution: For blob containers in Azure Storage, you recommend encryption that uses customer-managed keys (CMKs).
Does this meet the goal?

  • A. Yes
  • B. No

We need to use customer-managed keys.
Azure Storage encryption for data at rest.
Azure Storage uses service-side encryption (SSE) to automatically encrypt your data when it is persisted to the cloud. Azure Storage encryption protects your data and to help you to meet your organizational security and compliance commitments.
Data in Azure Storage is encrypted and decrypted transparently using 256-bit AES encryption.
Data in a new storage account is encrypted with Microsoft-managed keys by default. You can continue to rely on Microsoft-managed keys for the encryption of your data, or you can manage encryption with your own keys. If you choose to manage encryption with your own keys, you have two options. You can use either type of key management, or both:
* You can specify a customer-managed key to use for encrypting and decrypting data in Blob Storage and in Azure Files.
* You can specify a customer-provided key on Blob Storage operations. A client making a read or write request against Blob Storage can include an encryption key on the request for granular control over how blob data is encrypted and decrypted.
Note: Automated key rotation in Key Vault allows users to configure Key Vault to automatically generate a new key version at a specified frequency. You can use rotation policy to configure rotation for each individual key. Our recommendation is to rotate encryption keys at least every two years to meet cryptographic best practices.
This feature enables end-to-end zero-touch rotation for encryption at rest for Azure services with customer-managed key (CMK) stored in Azure Key Vault. Please refer to specific Azure service documentation to see if the service covers end-to-end rotation.

A: Workbooks provide insights about your threat intelligence
Workbooks provide powerful interactive dashboards that give you insights into all aspects of Microsoft Sentinel, and threat intelligence is no exception. You can use the built-in Threat Intelligence workbook to visualize key information about your threat intelligence, and you can easily customize the workbook according to your business needs. You can even create new dashboards combining many different data sources so you can visualize your data in unique ways. Since
Microsoft Sentinel workbooks are based on Azure Monitor workbooks, there is already extensive documentation available, and many more templates.
C: What is a threat intelligence report?
Defender for Cloud's threat protection works by monitoring security information from your Azure resources, the network, and connected partner solutions. It analyzes this information, often correlating information from multiple sources, to identify threats.
Defender for Cloud has three types of threat reports, which can vary according to the attack. The reports available are:
Activity Group Report: provides deep dives into attackers, their objectives, and tactics.
Campaign Report: focuses on details of specific attack campaigns.
Threat Summary Report: covers all of the items in the previous two reports.
This type of information is useful during the incident response process, where there's an ongoing investigation to understand the source of the attack, the attacker's motivations, and what to do to mitigate this issue in the future.
Incorrect:
Not B: When to use Jupyter notebooks
While many common tasks can be carried out in the portal, Jupyter extends the scope of what you can do with this data.
For example, use notebooks to:
Perform analytics that aren't provided out-of-the box in Microsoft Sentinel, such as some Python machine learning features
Create data visualizations that aren't provided out-of-the box in Microsoft Sentinel, such as custom timelines and process trees
Integrate data sources outside of Microsoft Sentinel, such as an on-premises data set.
Not D: Defender for Cloud offers security alerts that are powered by Microsoft Threat Intelligence. It also includes a range of advanced, intelligent, protections for your workloads. The workload protections are provided through Microsoft Defender plans specific to the types of resources in your subscriptions. For example, you can enable Microsoft Defender for Storage to get alerted about suspicious activities related to your Azure Storage accounts.

Question 10

Your company is developing a modern application that will un as an Azure App Service web app.
You plan to perform threat modeling to identity potential security issues by using the Microsoft Threat Modeling Tool.
Which type of diagram should you create?

  • A. system flow
  • B. data flow
  • C. process flow
  • D. network flow

Process flow diagrams are the result of a maturing threat modeling discipline. They genuinely allow incorporation of developers in the threat modeling process during the application design phase. This helps developers working within an Agile development methodology initially write secure code.
Application threat models use process-flow diagrams, representing the architectural point of view. Operational threat models are created from an attacker point of view based on DFDs. This approach allows for the integration of VAST into the organization's development and DevOps lifecycles.
Incorrect:
Not B: Data-flow diagrams are graphical representations of your system and should specify each element, their interactions and helpful context.
Data-flow diagrams are made up of shapes that create graphical representations of your system. Each shape represents a unique function. Each interaction is analyzed to help you identify potential threats and ways to reduce risk.
Using shapes correctly allows you to receive better input from colleagues and security teams. Everyone will then understand how the system works. It can also help them avoid going through countless design documents and development plans to get them up and running.
