Connected medical tools, known as the Internet of Medical Things, help patients but face dangerous cyberattacks. Stopping these digital threats requires strong detection systems. Researchers built new security tools using machine learning, where computers learn to spot danger. To protect sensitive hospital data, they used federated learning. This technique trains computers across separate devices without gathering everyone's private records into one place, allowing small, low-power medical devices to run lightweight programs. They also added an explanation method called SHAP to show exactly why a model flags a threat, making the results clear and reliable. Ultimately, the team created three lightweight models customized for different medical data types, giving medical networks better security without sacrificing privacy or computing power.
Imagine a group of doctors in different hospitals each keeping their own patient records private. They want to learn from each other's experiences to spot a new disease, but they cannot share the actual records. If they each only use their own data, they might miss patterns that appear across hospitals. In this paper, the doctors are hospitals with medical devices, the disease is a cyberattack, and the learning method is federated learning, which lets them build a shared detection model without exchanging private data.
Hospitals using connected medical devices face growing cyberattacks. Existing security solutions often require sharing sensitive patient data or use heavy models that drain device batteries. This work proposes detection models that learn from data across hospitals without sharing raw data, run on low-power devices, and explain why they flagged a threat, making them practical and trustworthy for real clinical use.
The work is evaluated only on the IoMT-TrafficData dataset, so its effectiveness on other IoMT environments or real-world deployments is not shown. The models are lightweight but their performance against sophisticated attacks is not detailed. The interpretability method (SHAP) adds transparency but may not capture all model reasoning. The federated learning approach assumes honest participants; malicious clients could degrade the model.
