IoMT Security Challenges and Solutions

In the rapidly evolving landscape of healthcare delivery organizations (HDOs), the integration of Internet of Medical Things (IoMT) devices has become instrumental for enhancing patient care and operational efficiency. Yet, this interconnected environment brings a host of security issues that require solid responses. In this article, we'll discuss these primary concerns. 

Insecure Medical Devices

In recent times, there has been a notable surge in cyber attacks targeting healthcare systems, thereby amplifying the risks associated with the exposure of patients, hospital information and service disruptions.

Infusion pumps, which make up 40% of a hospital's IoT footprint, heavily rely on firmware for regulation and administration. These devices utilize wireless connections to adjust medical parameters and medication dosages. Cyber threats on these pumps pose significant risks, as they can grant unauthorized access to alter medical settings. This not only endangers patient health and threatens sensitive data but could also influence the pump's functionality. Successful assaults could potentially exploit the hospital's extensive IoT network, jeopardizing other connected devices.

The susceptibility of Magnetic Resonance Imaging (MRI) systems to cyber threats is amplified by their connection to hospital networks, offering cyber attackers an opportunity to exploit vulnerabilities in outdated firmware. The manipulation of these vulnerabilities in MRI systems could lead to unauthorized access and modification of crucial medical data. This not only endangers diagnostic accuracy but also affects patient care.

The same vulnerability applies to insulin pumps, which are susceptible to remote manipulation by cyber attackers. This alarming risk could lead to unauthorized adjustments of the pump settings, leading to control over insulin delivery.

These examples represent only a fraction of the numerous IoT and IoMT devices connected to the internet in a hospital architecture, all susceptible to potential cyber attacks.

So many vulnerabilities, so little time

In a hospital ecosystem, managing threats to the Internet of Medical Things (IoMT) devices entails not only patching the device when a new vulnerability is discovered, but also promptly understanding potential vulnerabilities in the software used.

When a new flaw  is discovered in a medical device, information about this vulnerability is made public through the Common Vulnerabilities and Exposures (CVE) program. This assists IT managers and security teams in taking countermeasures.

However, the sheer volume of CVEs poses a daunting challenge, with over 211,890 distinct ones currently identified, and an additional 2,500 new vulnerabilities emerging each month. This landscape underscores the complexity and difficulty healthcare organizations face in effectively managing and securing their IoMT devices.

IoMT Long Lifecycles 

An additional challenge that presents itself in the world of medical devices is the lifespan of these devices. It's important to note that medical devices, given their crucial role in healthcare and patient welfare, typically have a longer lifespan compared to standard consumer devices. This longevity, while beneficial in terms of cost-effectiveness and durability, poses a unique problem.

The security protocols and safeguards that were developed and implemented at the time of the device's manufacturing may become antiquated as time progresses. As technology evolves and new threats emerge, these once robust security measures may no longer provide the necessary protection, potentially leaving the device and patient data vulnerable.
