Question 1 of 169
Scenario: Northstorm is an online retail shop offering unique vintage and modern accessories. It initially entered a small market but gradually grew thanks to the development of the overall e-commerce landscape. Northstorm works exclusively on line and ensures efficient payment processing, inventory management, marketing tools, and shipment orders. It uses prioritized ordering to receive, restock, and ship its most popular products.
Northstorm has traditionally managed its IT operations by hosting its website and maintaining full control over its infrastructure, including hardware, software, and data administration. However, this approach hindered its growth due to the lack of responsive infrastructure. Seeking to enhance its e-commerce and payment systems, Northstorm opted to expand its in-house data centers, completing the expansion in two phases over three months. Initially, the company upgraded its core servers, point-of-sale, ordering, billing, database, and backup systems. The second phase involved improving mail, payment, and network functionalities. Additionally, during this phase, Northstorm adopted an international standard for personal identifiable information (PII) controllers and PII processors regarding PII processing to ensure its data handling practices were secure and compliant with global regulations.
Despite the expansion, Northstorm's upgraded data centers failed to meet its evolving business demands. This inadequacy led to several new challenges, including issues with order prioritization. Customers reported not receiving priority orders, and the company struggled with responsiveness. This was largely due to the main server's inability to process orders from YouDecide, an application designed to prioritize orders and simulate customer interactions. The application, reliant on advanced algorithms, was incompatible with the new operating system (OS) installed during the upgrade.
Faced with urgent compatibility issues, Northstorm quickly patched the application without proper validation, leading to the installation of a compromised version. This security lapse resulted in the main server being affected and the company's website going offline for a week. Recognizing the need for a more reliable solution, the company decided to outsource its website hosting to an e-commerce provider. The company signed a confidentiality agreement concerning product ownership and conducted a thorough review of user access rights to enhance security before transitioning.
Based on the scenario above, answer the following question:
Which of the following situations represents a vulnerability in Northstorm's systems?
Correct Answer: C
