Hacking Internet of Medical Things (IoMT) Devices: What To Know

Modern technology has provided several innovations that has greatly improved an individual’s personal and professional lives. Across several industries, including the healthcare industry, the term Internet of Medical Things or IoMT has been applied in various technological advancements which have their own sets of advantages and disadvantages.

Here are some facts about IoMT,  a few examples, and why clients should also examine and prioritize its Internet of Medical Things (IoMT) Security features:

What is Internet of Medical Things or IoMT?

The Internet of Medical Things refers to the collective group of medical devices and technologies that are connected to various healthcare IT systems and computer networks. Many of which are:

– Wi-Fi capable

– Can be linked to various cloud storage platforms

– Captures and records data which will be analyzed later

Some examples of IoMT include patient monitoring systems, wearable health devices like fitness watches that can be used to send health information to caregivers, and dashboards on hospital beds and infusion pumps that allow the proper distribution of medications. All of which can help improve the patient’s quality of life while also streamlining various medical procedures that usually take a lot of time.

With seemingly limitless possibilities ahead of it, the future for IoMT seems to be brighter than ever. However, this isn’t always the case as various issues have been plaguing some of these devices for a while, many of which involve security issues.

What are some security issues that IoMT devices face?

Many IoMT handle various sensitive data that are relevant to the patient’s health status and vital measurements, some of which may include medical history, sensitive family information, and even a list of medications, which require proper handling and authentication. Some of the most vulnerable aspects most IoMT fall prey to include:

   – Poor Physical Security

Aside from its internal security software, external factors also play a crucial role in affecting the integrity of the device or machine. For instance, wearable watches that monitor vital signs may be deemed ineffective if they are easily damaged by water, sweat, and overheating, which eventually render such devices as virtually useless.

   – Lack of proper authentication and authorization

Another is the lack of authentication and authorization that some of these devices may have. Considering that many of these devices carry out very important tasks like dispensing medications, monitoring vital signs, and recording crucial patient information, the lack of security in authorizing the right doctor for the patient still remains as a legitimate concern that can make the entire operation vulnerable to theft and tampering.

Improving the IoMT security features: Where are we now?

In an effort to prevent these shortcomings from hindering the growth of advancing technology, certain bodies like the FDA have taken major steps in improving the monitoring of IoMT cybersecurity features, one of which is called the UL 2900 for Medical Device Cybersecurity, a standard that covers important steps and protocols needed to ensure online safety. Some of these features include:

– Listing the general requirements of evaluating and testing network-connectable devices in regards to its vulnerability, malware, and overall weaknesses in the program

– Emphasizing the need to document a system’s overall risk tier

– Using a risk assessment system that helps prioritize machine to machine connectability over non-connectable devices

Additionally, other steps to ensure safety and security are also included, some of which are:

– Providing threat mitigation training to clinicians and medical health technicians

– Segmenting various networks for a more thorough implementation of security checks and to ensure that no stone is left unturned

– Incorporating homomorphic encryption systems to protect vital patient information as well as to keep third parties from gaining access to sensitive data

With all these developments in tow, it’s no secret that IoMT is still in the development phase and is showing signs of continuous progress. However, since one cannot wait for a system to become fully operational overnight, it helps to make a few security investments that can at least improve the system they have now. This includes contacting with a third-party security company to ensure that all devices are in accordance to the UL 2900 List of Recognized Standards for Medical Device Cybersecurity.

One example is Alpine Security, which protects and preserves data effectively and ethically. Many experts hired by this company routinely perform various testing, auditing, and security consulting processes that help manufacturers secure their device and systems, and prevent them from causing any unwanted harm. Additionally, the company also has experience with dealing in commercial aircraft systems, as well as government agencies.

Conclusion

Modern technology has come a long way in such a short period of time. Nevertheless, experts believe that security improvements should be prioritized to ensure safety and security for various users. To do this, users must educate themselves on the possible risk factors that could potentially affect the tech’s services.
