Importance of cyber security in healthcare
Cyber-security considerations and measures are extremely important in healthcare more than in any other industry, in my view. Also consider existing legislation around healthcare and patients' data protection as well. For the case of medical devices, they must design and implemented with serious consideration for security especially when it concerns safety of patients and the associated data.
Risk based approach and threat model is kickoff for each device. Connect it to Business impact analyses (if applicable consider impact of losing confidentiality, integrity, availability,… of device/functionality/data) and you will know exactly how important is for you the mitigation of cyber-security risks.
Each device might have variety of interfaces, stored data etc. Malfunction of implantable device, or misuse, could result in wide range of impacts (health of customer, business disruption/reputation damage, legislation & regulation fines,…).
By end of the day, for some implantable devices could be cyber-security even non-applicable. For other devices, it might be business and life crucial.
Cyber security in healthcare highly important. In fact, healthcare companies and organization have suffered from constant cyber-attacks and are considered one of the major targets for hackers. Healthcare does not mean only medical information, but also human lives. Taking into consideration that any medical device connected to a network is potentially at risk from being taken over and exploited by hackers we should not consider only lost of money or reputation, but also the loss of lives. Today, in the era of technology, we already have smart cardiac devices, like pacemakers and defibrillators as well as smart pumps, like an insulin pump that remotely inject medicine into the body. Hacking such a device is a real life threat. Medical privcy should not be treated differenly and its importance is known to us all. To enforce that we have multiple regulations and standards such as HIPAA and ePHI. In addition to the importance of keeping the patients medical records private, healthcare companies who do not protect their patients privacy are subjected to legal panelties. All this means that cyber security in healthcare should be a great concenr and should be taken seriously and without compramises.
Cyber-security is important to save and share information. Technology enables professionals to quickly send information to colleagues and patients, it saves storage costs too. Preventing attacks helps to keep information confidential, this could be relevant for legal reasons. Having now a large amount of this information digitized, this is one of the best source of information about anyone. As per an article released by Forbes, already in 2015 healthcare was the most targeted industry for security attacks, https://www.forbes.com/sites/stevemorgan/2016/05/13/list-of-the-5-most-cyber-attacked-industries/#63683546715e.
A Greenfield, Ind. based Hancock Health hospital paid extortionists roughly $60,000 to end a ransomware outbreak that forced staff to use pencil-and-paper records. Last year, Erie County Medical Center in Buffalo, New York, spent almost $10 million rebuilding its system after declining to pay attackers $30,000 to unlock the system.
Cybersecurity is important everywhere. So as in healthcare. Especially, healthcare data is too personal. Having said that, healthcare has bigger cybersecurity challenges with growing IoT things. Devices that read patient data are connecting to the internet and cloud. That brings the concern on the firmware, network, and servers the whole system is using.
Another thing- I do not see any standard OS layer or firmware layers for such devices(specially most IoT). Unlike household devices where we know, these are either iOS, Android or Microsoft. But for devices in IoT (And that goes to all IoT) have nothing like this. So, managing these devices is also a challenge.
The more we bring devices into the system, more challenges we are gonna get.
There is another aspect - of human error. There are cases when the staff accidentally leaked the data because of lack awareness of cybersecurity. I think training is also a very important part of this.
