The mass vaccine roll-out across the world offers hope that by the summer we will see a glimmer of normality start to return to our lives. However, until then we also have to consider the profound challenges of delivering and administering vaccines at scale. The logistical hurdles have been well documented but the cybersecurity risks less so and that’s what I want to shed light on.We have the equipment you need to upgrade or install a whole new nurse call system. Let us help you build a customized system that serves the needs of your staff and the patients.There are two areas that concern me in particular. First is the persistence of legacy technology (e.g. workstations and network infrastructure) and unpatched devices that abound in most healthcare systems such as the NHS in the UK. The second are the increasing risk profiles associated with network connected medical devices which we can refer to as Internet of Medical Things (IoMT) Devices. Taken together these present significant clinical and organisational risks.For example, a ‘standard’ opportunistic ransomware attack targeting a hospital or vaccination hub that makes patient administration and EMR systems unavailable would significantly disrupt vaccinations simply because patient details could not be validated. Take this a step further with a slightly more targeted attack, and you could see pharmacy systems and IoMT devices such as medication fridges and dispensing cabinets being compromised. These would have a more profound impact, as with the most temperature and time sensitive vaccines we could see the loss of highly valuable batches as a consequence of this.
