Introductionin The Previous Lab You Created A Kanban Board One Of Th ✓ Solved

Introduction In the previous lab, you created a Kanban Board. One of the tasks you created in Module-2 should be to perform threat modeling for the blog website you have been developing for your customer. You decided to perform threat modeling after the vulnerability management team discovered a critical vulnerability on the web service. The blog site is in the staging environment. It will be migrated to the production environment in the Azure cloud next month.

The blog site will eventually serve as an information sharing and collaboration portal for authenticated users. It will use an SQL database at the backend. As the project manager, you want to see the Data Flow Diagram (DFD) that shows the communications between various entities and to perform threat modeling with your team to explore threats and suggest countermeasures.

Review all of the threats that are automatically devised by the tool 3. Add two more threats. Take a screenshot of the new threats. Part 3: Devise Mitigations and Change Threat Properties 1. For the threats you added, change the status to Mitigated and fill out the "Possible Mitigations" section.

2. Choose one threat, change the status to "Not Applicable". Fill out the justification section. 3. Choose another threat, change the status to "Need Investigation".

Adjust the severity level and write a justification for it. Take the screenshots that show the result of your actions. Part 4: Reporting 1. Click the Reports menu and "Create Full Report". 2.

Review the downloaded report. Part 5: Project Management 1. Log into your Azure Board and create a task for the threat that needs investigation. 2. Take the screenshot of the Azure board showing the tasks.

Submit the Full Report and screenshots. Microsoft Threat Modeling Tool 2016 Guidance The below figure shows how to switch to analysis view. In the analysis view, you see some generic threats, as shown below. Right-click on the objects you created (Sample objects: “Requestâ€, “Response,†and Trust Boundaries). You will see the "Add User-defined Threat" option.

Once you click on "Add User-defined Threat", the threat list will show the new threat (1). Fill out the details of the new threat (2).

Threat Modeling for a Blog Website: A Comprehensive Approach

Introduction

In software development, especially when dealing with web applications, threat modeling is an essential practice that helps identify, prioritize, and address potential vulnerabilities. The case of the web-based blog site, set to launch in the Azure cloud, highlights the importance of rigorous threat modeling—especially after the discovery of a critical vulnerability in similar web services. This assignment follows a structured approach using the Microsoft Threat Modeling Tool to create a Data Flow Diagram (DFD), analyze threats, devise mitigations, and employ project management techniques to track issues in Azure Boards.

Creating the Data Flow Diagram (DFD)

A Data Flow Diagram (DFD) is a visual representation that illustrates how data moves throughout a system. It includes data stores, processes, interactors, data flows, and trust boundaries. In the context of the blog website, the DFD needs to encapsulate the interaction between authenticated users, the web application, the SQL database, and any external services.
Entities in the DFD Include:
- Interactors: Authenticated users of the blog.
- Processes: User authentication, posting of blogs, comments, and retrieving blog posts.
- Data Stores: SQL database that stores user data, blog posts, and comments.
- Data Flows: Data exchanged between the interactors and processes, such as user login information, blog content, and feedback.
- Trust Boundaries: Points where data transitions between less trustworthy and more trustworthy components. For example, the boundary between the web application and the SQL database.
The DFD, once created visually using the Microsoft Threat Modeling Tool, highlights the flow of sensitive information and helps identify potential security risks.

Review of Threats

Switching to the analysis view in the Microsoft Threat Modeling Tool reveals a variety of automatically identified threats based on the STRIDE model. STRIDE encompasses the major attack vectors that a system could face:
- Spoofing: Impersonation of users.
- Tampering: Unauthorized modification of data in transit or at rest.
- Repudiation: Users denying actions taken.
- Information Disclosure: Unauthorized access to sensitive information.
- Denial of Service: Disrupting the availability of services.
- Elevation of Privilege: Gaining unauthorized permissions.
To enhance our threat model, we added two specific threats: “SQL Injection” and “Credential Theft”. These threats are especially pertinent to systems relying on SQL databases and user authentication processes.

Devise Mitigations and Change Threat Properties

Following the identification of new threats, it is crucial to outline mitigations. Possible mitigations for the added threats could include:
1. SQL Injection:
- Implementing parameterized queries.
- Regular database security audits.
- Input validation to filter out harmful data.
2. Credential Theft:
- Enforcing strong password policies.
- Utilizing two-factor authentication (2FA).
- Conducting regular security training for users on recognizing phishing attacks.
After implementing mitigations, the status for these threats was changed to "Mitigated" and their mitigations noted in the tool.
In addition, one threat ("Denial of Service") was marked as "Not Applicable" because its likelihood is minimal due to the blog being a low-traffic application. The justification mentioned that the hosting infrastructure leverages Azure's built-in DDoS protection features.
Another threat, “Elevation of Privilege”, was marked as "Need Investigation." Adjusted severity was increased to 'High’ due to potential risks involving authorized access breaches, which can severely impact both data integrity and user trust. Justification elaborated on how a security breach could compromise authenticated accounts, leading to catastrophic consequences.

Reporting

The full report generated from the Microsoft Threat Modeling Tool captured all aspects of the modeling process, including the DFD, identified threats, mitigations, and the current security status of threats. The report provides a centralized view, aiding stakeholders in understanding the potential vulnerabilities present in the blog web application.

Project Management

To effectively manage the threats discovered during this process, a task was created in the Azure Boards to focus on the threat needing investigation—“Elevation of Privilege.” This task allows for tracking progress in investigating the threat and ultimately implementing the necessary mitigating controls.

Conclusion

Threat modeling is a critical practice for ensuring the security and integrity of web applications, particularly in a cloud environment. By utilizing the Microsoft Threat Modeling Tool, the identification of threats through a structured process helps prioritize security efforts. Through the creation of a DFD, identifying and addressing threats, and tracking these issues via project management tools like Azure Boards, we can significantly minimize the potential impact of vulnerabilities on our blog website.
