iSACA Cybersecurity Fundamentals Certification Practice Exam

Which of the following can be considered a privileged service?

1. Email services

2. File transfers

3. HTTP services on port 80

4. Streaming services

The correct answer is: HTTP services on port 80

The correct choice refers to HTTP services on port 80 as a privileged service because it is a well-known protocol commonly used for web traffic. In the context of cybersecurity, "privileged services" often implies services that handle sensitive data or are critical for communication and access in a networked environment. HTTP is foundational for web applications, including those that require secure transactions, which can involve confidential user information. Privileged services, as a category, include those that have elevated access within the network architecture or that can interact with other services in a way that requires special privileges due to the nature of the data they transmit or the operations they perform. Since HTTP on port 80 is crucial for delivering web content, it can be seen as requiring a certain level of privilege and security oversight. In contrast, while email services, file transfers, and streaming services may handle data, they typically operate under different layers of protocol and do not inherently denote the same level of privilege. Email services often function on various designated ports that may not require elevated privileges as part of their standard operation; file transfers can utilize FTP or other protocols which might not have the same level of oversight; and streaming services are more focused on media delivery which does not necessitate the same access considerations as web
