Scenаriо: Yоu аre а student at Geоrge Mason University (GMU) who is majoring in Cybersecurity Engineering. As part of your senior design course, you’ve been given privileged access to GMU’s internal web portal, MyGMU, which hosts course registration, financial aid details, and student ID services. The system also allows students to request transcripts, manage meal plans, and reset their university login credentials. One evening, you log into MyGMU from the library to register for summer courses. While reviewing the network traffic in Burp Suite for your senior design project, you notice that sensitive data such as your student ID, course registration tokens, and meal plan balance are transmitted in plaintext between the browser and the server during certain requests. Since you’re curious, you test a few more pages. On one screen, the GET request for the course schedule includes a URL parameter like ?userID=128349 You change it to a different user ID: ?userID=128348 and unexpectedly view another student’s schedule without needing to authenticate as them. Instead of exploiting this further, you report this issue to GMU’s IT help desk and document the behavior. Days later, you are contacted by the university’s Chief Information Security Officer (CISO), who acknowledges the report and explains that the issue is part of a broader vulnerability in how the portal handles authorization and session management. GMUU takes steps to patch the issue by enforcing stricter session validation, migrating all traffic to HTTPS, and launching a student-facing security awareness campaign. You’re praised for ethical behavior and later asked to help lead a student panel on responsible disclosure and web application security.

Questiоn 3 (10 pоints) SecureBаnk, а regiоnаl banking institution in Yorkshire, Virginia, is developing a new online fund transfer feature for its mobile application. The development team is primarily focused on ensuring the functionality and usability of the feature for legitimate users. However, the security team wants to proactively identify potential abuse scenarios. They decide to employ misuse case modeling as part of their security analysis. During a misuse case workshop, the team identifies several potential threats related to the fund transfer feature. One scenario involves a malicious actor who gains unauthorized access to a user's account. This actor then attempts to initiate multiple small fund transfers to various external accounts over a short period, aiming to evade standard fraud detection thresholds that typically flag large, single transactions. In the context of SecureBank's new online fund transfer feature and the identified misuse case scenario, which of the following security countermeasures would be the MOST directly effective in mitigating the risk posed by the described malicious activity, as informed by the misuse case analysis?
InnоvаteSоft, а smаll startup based in Yоrkshire, Virginia, is developing a new cloud-based project management tool for collaborative software development teams. Their initial focus was on rapid feature deployment to capture early market share. However, as they prepare for wider release and begin onboarding larger enterprise clients, concerns about application security have grown. They decide to proactively implement elements of the Microsoft SDL into their existing development process. During a security review, an external penetration testing team identifies several medium-severity vulnerabilities, including a cross-site scripting (XSS) flaw in the user profile management section and an SQL injection vulnerability in the task assignment module. InnovateSoft's development team, now attempting to integrate SDL practices retroactively, is debating the most effective initial steps to address these findings within the context of the SDL. Considering InnovateSoft's situation and the principles of the Microsoft SDL, which of the following would represent the MOST crucial initial step they should take to address the identified vulnerabilities and integrate SDL practices?

GlоbаlECоm, а rаpidly expanding e-cоmmerce platform headquartered in St. Petersburg, Florida, handles thousands of online transactions daily. It maintains a large customer database containing sensitive information such as names, addresses, email addresses, phone numbers, and encrypted payment details. Its security infrastructure includes a firewall, an intrusion detection system (IDS), and regular vulnerability scanning. However, security resources have been stretched due to the company's rapid growth. On the morning of April 28, 2025, the GlobalECom security operations center (SOC) received an alert from its IDS indicating unusual outbound traffic originating from its primary database server. Further investigation revealed a sustained data exfiltration event over several hours. The attackers had seemingly bypassed the initial firewall rules. Analysis of the database server logs showed a series of suspicious SQL commands executed from an internal IP address that was not associated with any legitimate administrative activity. These commands appeared to be targeting the customer database tables. The attackers had escalated privileges on a compromised web server, likely through a previously unknown vulnerability in a recently deployed website plugin. From this foothold within the network, they could pivot and gain access to the database using stolen credentials that were likely stored in plaintext on the compromised web server (a lapse in security best practices). Upon detecting the data breach, GlobalECom's security team swiftly initiated their incident response plan, prioritizing containment by isolating the compromised database server and taking the affected web server offline for forensic analysis, while simultaneously informing key stakeholders. A thorough investigation ensued, involving forensic analysis of the web server to pinpoint the exploited plugin and attack methods, detailed log analysis to trace the attacker's actions and identify compromised data, a comprehensive vulnerability scan to uncover other weaknesses, and a data breach assessment to understand the scope of customer impact. Subsequently, remediation efforts focused on patching the vulnerability, hardening systems, enforcing strong credential management with MFA, enhancing network segmentation, and improving monitoring and alerting capabilities. Finally, post-incident activities included transparent customer notification, ensuring legal and regulatory compliance, mandating security awareness training, and establishing a long-term strategy with increased security investment and integrated secure development practices.
