What is a key characteristic of a supply chain failure in cloud computing?

  1. Unencrypted data transmission

  2. Hidden dependencies in applications

  3. Weak user authentication

  4. Inefficient data management

The correct answer is: Hidden dependencies in applications

A key characteristic of a supply chain failure in cloud computing is hidden dependencies in applications. In this context, supply chain failures can arise when an application relies on third-party components or services that are not adequately assessed for security risks. These hidden dependencies can create vulnerabilities that attackers might exploit, leading to potential breaches or system failures without the organization's knowledge. Organizations often utilize various libraries, APIs, and services that they might not fully control or understand, which can introduce risks if those components are compromised. If an external dependency fails or is manipulated, it can cascade down to affect the entire application stack, potentially leading to significant disruptions or data breaches. Ensuring proper visibility into all dependencies, as well as regular assessments of the security posture of third-party services, is crucial in mitigating the risks associated with hidden dependencies. This focus on comprehensive oversight is particularly important in cloud environments where multiple vendors and services are often interconnected.
