Question

You are a cybersecurity consultant for a healthcare organization that utilizes Internet of Medical Things (IoMT) devices, such as connected insulin pumps and heart rate monitors, to provide improved patientcare. Recently, the organization has been targeted by ransomware attacks. While the IT infrastructure was unaffected due to robust security measures, they are worried that the IoMT devices could be potential entry points for future attacks. What would be your main recommendation to protect these devices from such threats?

Options

  • ADisable all wireless connectivity on IoMT devices.
  • BRegularly change the IP addresses of all IoMT devices.
  • CUse network segmentation to isolate IoMT devices from the main network.
  • DImplement multi-factor authentication for all IoMT devices.

Why each option

To protect IoMT devices from ransomware, the main recommendation is to isolate them from the main network using network segmentation, preventing lateral movement of threats.

ADisable all wireless connectivity on IoMT devices.

Many IoMT devices rely on wireless connectivity for their functionality and data transmission, making disabling it impractical and often rendering the devices useless.

BRegularly change the IP addresses of all IoMT devices.

Regularly changing IP addresses offers negligible security against ransomware, which exploits vulnerabilities and misconfigurations rather than static network addresses, and creates operational complexity.

CUse network segmentation to isolate IoMT devices from the main network.Correct

Network segmentation creates isolated zones, preventing ransomware from spreading from compromised IoMT devices to the main network or other critical systems. This minimizes the attack surface and blast radius, ensuring that a breach in one segment does not jeopardize the entire infrastructure.

DImplement multi-factor authentication for all IoMT devices.

Many IoMT devices lack the user interface or processing power to effectively support traditional multi-factor authentication (MFA), and MFA primarily secures user access, not device-level vulnerabilities exploited by ransomware.
