IoMT Security: The Importance of Visibility

The More You Have; The Less You See! 

Hospitals around the globe have realized that proper cybersecurity is an utmost necessity for them in today’s current day and age. With the constant influx of IoT (Internet of Things) and IoMT (Internet of Medical Things), hospitals need to find a way to keep track of the connections and potential risks that come with establishing a medical network. However, a lack of Layer 1 visibility prevents effective cybersecurity efforts; when device visibility is not up to par, a hospital’s entire network is at risk due to inefficient asset management. This is especially perilous as many IoMT devices have a higher risk posture since they function on vulnerable platforms, such as Raspberry Pis, which do not get detected by existing security solutions.

Further, hospitals should have the proper capabilities to monitor devices for potential security breaches or attacks. Cyber-attacks can approach their targets in multiple directions, such as supply chain manipulations, insider threats, and device impersonation.

The IoMT global hospital market in 2017 was valued at $41 billion; now, in 2022, its current valuation is $158 billion. This astronomical growth rate shows how much the medical industry has adapted these types of devices. That being said, this has led to increased cybersecurity challenges as there are now many more devices to manage. On top of this, there is also the issue of device vendor sprawl; the lack of Layer 1 visibility means ensuring a device’s integrity is nearly impossible.

The Positivity of Hospital Visibility   

There are three things that every hospital should have when it comes to cyber security that are exclusive to HAC-1 and not found in other current security platforms: visibility, hardware access control and Rogue Device Mitigation (RDM). However, the keystone that makes this system effective in “holding up the stone archway”, in providing the proper defense, is visibility – specifically at Layer 1. Having a complete asset visibility is mandatory for effective asset management. Through hardware access control, enterprises can implement a Zero Trust Hardware Access approach that implements microsegmentation protocols based on a device’s identity. Furthermore, Layer 1 visibility allows for the instant detection and identification of rogue devices, which can then get blocked immediately. Ultimately, Layer 1 visibility offers complete asset visibility, which works in tandem with other security software and protocols in order to provide comprehensive cybersecurity in hospitals.

Cataract? More like don’t Get Hacked!  

Just like a “cataract”, which is a medical condition that impedes the vision of a person due to the formation of proteins on the lens of the eye leading to cloudy vision, hospitals must ensure that they don’t lose visibility to the constant formation of technological device advancements creating an ever-so-cloudy landscape of network vulnerabilities. 

Sepio’s HAC-1, provides Layer-1 protection and visibility in order to instantly detect the presence of unknown devices and prevent any attack from taking place. HAC-1’s in-depth visibility makes sure that no hardware device goes unnoticed and unmanaged, detecting hardware attacks that target IoMT devices and other IT/OT/IoT devices. Furthermore, HAC-1 ensures a rigorous policy enforcement mechanism, and RDM instantly blocks any unauthorized or malicious hardware. This is HAC-1’s Zero Trust Hardware Access method, ensuring that attacks are stopped dead in their tracks.
