Purposeas A Cybersecurity Risk Analyst You Have Been Tasked With A Ne

As a cybersecurity risk analyst, you have been tasked with a new project. You will conduct a qualitative cybersecurity risk assessment for a cloud-based software service. In addition, you will outline mitigation strategies for all of the risks you have identified for the existing version of the service. Finally, you will propose a process for integrating risk assessment into a software development life cycle. After the project is completed, your hope is to publish a case study to be used as a model for academia and/or for organizations by submitting the case study to a peer-reviewed cybersecurity or information security journal.

Assignment Instructions (If applicable, you can use the same open source project used in Unit 3.) For Assignment purposes, select a multi-layered (presentation layer, business layer, and database layer) Web-based open source project. Assume that the presentation layer resides on a dedicated server in the company’s DMZ. The other two layers of the software are behind the corporate firewall and can reside on one or two dedicated servers.

The Web application is accessible from the Internet and is browser based. Firefox™, Chrome™, Internet Explorer®, and Safari® are the supported browsers, or you have the option to use a multi-layered application that you have access to. However, notify your instructor if this is the case and explain the situation. Conduct a qualitative cybersecurity risk assessment on the software product/service. This can include internal and external risks.

Do not forget to consider the operating systems involved, what programming languages are used, and some of the inherent risks for the particular programming language(s). The same goes for the database and web servers used. Identify at least five cyber risks and describe each in detail and why it is a risk for this system. Outline mitigation strategies for each of the cyber risks you have identified. Support your research and assertions with at least three credible sources.

You may use peer-reviewed articles, trade magazine articles, or IT research company (Gartner, Forrester, etc.) reports to support your research; you can use the Library to search for supporting articles and for peer-reviewed articles. Wikipedia and similar sources are unacceptable.

Assignment Requirements: At least 3–4 pages of content (exclusive of title page, etc.), using the format from the peer-reviewed journal you found. APA style. At least three credible sources. No spelling errors. No grammar errors. No APA errors.

Paper For Above instruction

In the rapidly evolving landscape of cybersecurity, conducting thorough risk assessments is pivotal, especially for cloud-based applications that operate across multiple layers of infrastructure. This paper presents a qualitative cybersecurity risk assessment for a hypothetical multi-layered web-based open source project, focusing on identifying potential risks and proposing mitigation strategies. The goal is to develop a comprehensive understanding of vulnerabilities intrinsic to such systems and recommend best practices for integration into the Software Development Life Cycle (SDLC).

The selected system features three core layers: the presentation layer, business layer, and database layer. The presentation layer, hosted on a server in the Demilitarized Zone (DMZ), renders the web interface accessible via popular browsers such as Chrome, Firefox, Safari, and Internet Explorer. This configuration offers accessibility while also exposing certain attack surfaces. The backend layers— business logic and database—are protected behind the corporate firewall, serving as the backbone for data processing and storage.

Several inherent risks stem from this architecture. The web server's exposure in the DMZ makes it vulnerable to external threats like Distributed Denial of Service (DDoS) attacks, web application exploits such as cross-site scripting (XSS), and infiltration attempts through unpatched vulnerabilities. The programming languages used—such as PHP or JavaScript for the front end, and potentially Java or Python for the backend—bring specific risks related to insecure coding practices, buffer overflows, or injection attacks. The operating systems, whether Linux or Windows, also present their own vulnerabilities if not appropriately secured and regularly updated. The database management system, such as MySQL or PostgreSQL, could be susceptible to SQL injection, data leakage, or unauthorized access if proper controls are not enforced.

Key risks identified include:

1. Web Application Vulnerabilities (XSS, CSRF)

Web applications are frequently targeted for cross-site scripting and cross-site request forgery attacks, which can manipulate user sessions or extract sensitive data. Such vulnerabilities often arise from poor input validation or insecure coding practices. Attackers exploit these weaknesses to inject malicious scripts or hijack user credentials, leading to data breaches or session hijacking.

2. Inadequate Authentication and Authorization Controls

Weak authentication mechanisms, such as simple passwords or flawed multi-factor authentication implementations, increase the risk of unauthorized access. This could enable attackers to access sensitive data or administrative controls, compromising entire systems.

3. Insufficient Server and Network Security

The web server in the DMZ might lack proper configuration or updated security patches, making it vulnerable to exploitation. Network misconfigurations, such as open ports or lack of intrusion detection systems, compound this risk.

4. Database Vulnerabilities

Without proper input validation and privileged access controls, databases can be susceptible to SQL injection, leading to data exfiltration or corruption. insecure default configurations and unpatched software further exacerbate this risk.

5. Insecure Programming Languages and Development Practices

Programming languages like PHP, JavaScript, or Python have inherent risks if insecure coding practices are employed. For example, insecure handling of user input or lack of sanitization can open doors for injection attacks, compromise data integrity, or lead to remote code execution.

Mitigation strategies for these risks include implementing secure coding standards, regular patch management, and continuous monitoring. For XSS and CSRF, input validation, proper encoding, and anti-CSRF tokens are essential. Strong authentication mechanisms, including multi-factor authentication and robust password policies, reduce unauthorized access risks. Ensuring that server configurations follow security best practices and are regularly updated mitigates vulnerabilities at the network perimeter. For database security, employing parameterized queries, least privilege access, and audit logging are effective controls. Finally, adopting secure development lifecycle practices—such as code reviews, static code analysis, and security training—can minimize risks associated with insecure programming languages.

Supporting these strategies with credible sources, such as OWASP guidelines, NIST frameworks, and recent research articles, reinforces the importance of a proactive security posture. Integrating these risk assessments and mitigation strategies into the SDLC enhances overall system resilience and reduces the likelihood of successful cyber attacks, thereby protecting organizational assets and customer trust.
