Internet of Medical Things (IoMT) devices are connected medical devices and applications that leverage the Internet to improve healthcare delivery. These devices use sensors. automatic system and machine learning to reduce the need for human intervention.

Broadly IoMT has been categorized in three areas:

Remote Patient Monitoring
Medical Device Gateways
Emergency Response & Support System

What is Remote Patient Monitoring ?

Remote patient monitoring (RPM) is a health care devices that uses digital technology to collect, disseminate, and analyze patient health data outside of traditional clinical locations, such as their homes. This approach helps healthcare providers track patients. Delivering timely intervention and improving overall care reduces.

Examples:

Smart Pills
Smart Watch
Wearable ECG Monitors
Heart Rate Monitor
Mood Monitors
Connected Insulin Pen
Biosensors : Monitor Physiological Indicators
Smart Inhalers etc..

What Are Medical Device Gateways?

Medical Device Gateways are hardware or software systems that enable the integration and communication of medical devices with healthcare networks, systems, and applications. These gateways collect, process, and securely transmit data from connected medical devices to centralized healthcare platforms like Electronic Health Records (EHRs) or Remote Patient Monitoring (RPM) systems.

Examples:

Capsule Technologies (formerly Capsule by Qualcomm Life)
Cisco IoT Medical Gateway
Advantech Medical Gateway (WISE-3610)
Intel Health Application Platform (HAP)
ResMed AirView
Philips HealthSuite Platform
Bosch Health Buddy
Medtronic CareLink Network
Fitbit Health Solutions Gateway
Garmin Health Enterprise Gateway
OpenMRS with IoT Integration
IoTivity

Emergency Response & Support System

The Emergency Response & Support System (ERSS) in IoMT (Internet of Medical Things) is a specialized framework that leverages connected medical devices, sensors, and data analytics to enhance emergency response and patient care in critical situations.

Key Components of ERSS

Emergency Detection Algorithms such as AI and machine learning models analyze data in real time to identify anomalies or emergencies (e.g., arrhythmia, falls, or sudden spikes in glucose levels).
Alert Mechanism such as sending SOS signals to healthcare providers or emergency responders when critical thresholds are breached.
Cloud-Based Platforms store and process large volumes of data from multiple devices.
Integration with Emergency Services: Automatically notifies 911 (or local equivalents) with relevant medical information etc.
Physical medical facilities including devices to support and contain critical medical incidents.

Applications of ERSS in IOMT

Cardiac Emergencies such as Wearables detect arrhythmias or heart attacks and alert healthcare providers.
Diabetes Management such as continuous glucose monitors (CGMs) detect dangerous blood sugar levels.
Post-Surgery Monitoring such as Wearables monitor recovery metrics and alert doctors to complications like infections or clot formation.

Security challenges of in (Internet of Medical Things) - IoMT

Data Privacy and Security: Ensuring sensitive medical data is protected in transit and in store from breaches or misuse.
Regulatory Compliance: Ensuring devices meet healthcare standards and legal requirements globally such as Health Insurance Portability Accountability Act - HIPAA etc.
Blockchain for Data Security: Ensuring secure, tamper-proof storage and sharing of medical data.

Security threats targeting IoMT channel...

Eavesdropping (Data Interception) - Attackers intercept unencrypted communication between IoMT devices, such as between wearable health monitors and central servers.
Signal Jamming - Malicious actors disrupt IoMT device communication channels using radio frequency (RF) jamming or electromagnetic interference.
Man-in-the-Middle (MitM) Attacks - An attacker intercepts and alters communications between IoMT devices and their controllers without detection.
Replay Attacks - Attackers capture and resend legitimate data packets to manipulate IoMT devices
Weak Encryption or Lack of Encryption
Protocol Vulnerabilities - IoMT channels often rely on standardized communication protocols (e.g., Bluetooth, Zigbee, Wi-Fi), which may have inherent vulnerabilities.
Cross-Site Scripting (XSS) and Injection Attacks - Attackers inject malicious code into IoMT web portals or APIs used for communication.
Over-the-Air (OTA) Update Exploits - IoMT devices often use OTA channels to update firmware, which can be hijacked if not properly secured.
Insider Threats - Malicious insiders may exploit access to IoMT channels to steal or manipulate data.
API Exploits - IoMT systems often communicate through APIs, which, if poorly secured, can be exploited for unauthorized access.

Mitigation Strategies for IoMT Channel Security

Encryption: Use end-to-end encryption (e.g., TLS/SSL) for all data transmissions.
Authentication: Implement multi-factor authentication for device access.
Network Segmentation: Separate IoMT devices from other network traffic to limit attack surfaces.
Regular Updates: Patch known vulnerabilities in communication protocols and device firmware.
Threat Detection: Monitor IoMT channels for suspicious activity using intrusion detection systems (IDS).
Secure APIs: Validate input and enforce strict authentication for all APIs.
Protocol Hardening: Use secure versions of protocols (e.g., WPA3 for Wi-Fi) and disable unused communication features.
