Certified Information Systems Auditor (CISA) — Question 1100

A health care organization utilizes Internet of Things (IoT) devices to improve patient outcomes through real-time patient monitoring and advanced diagnostics. Which of the following would BEST assist in isolating these devices from corporate network traffic?

Answer options

• A. Internal firewalls
• B. Blockchain technology
• C. Content filtering proxy
• D. Zero Trust architecture

Correct answer: A

Explanation

Internal firewalls are designed to create zones within a network, allowing for the isolation of IoT devices from other corporate network traffic, thereby enhancing security. Blockchain technology does not provide network segmentation; it is primarily used for secure transaction records. A content filtering proxy focuses on managing internet content access and does not specifically isolate devices. Zero Trust architecture is a security model that assumes no inherent trust but does not specifically address the isolation of IoT devices from the corporate network.
