As a member of the Board of Directors of the IEEE Consultants Network of Silicon Valley, I am arranging two evening meetings:
Tuesday, June 13, 2023, 7:00 PM:“Cybersecurity for Industrial Control Systems and Operational Technology” presented by Mario Garcia, Supervisory Cybersecurity Advisor, Cybersecurity and Infrastructure Security Agency (CISA) at U.S. Department of Homeland Security and David Snyder of 42TEK LLC. In-person in Milpitas, CA and on Zoom. Pre-registration required at https://californiaconsultants.org/event/cybersecurity-for-industrial-control-systems/.
<TBD – probably 4th quarter 2023>:“Cybersecurity for Satellite Systems” – a panel discussion on how to protect space systems. Details and registration will be posted at https://californiaconsultants.org/events/ as the date gets closer. Topics to include:
MOVE Community Outreach, an IEEE-USA Initiative, is an emergency relief program committed to assisting victims of natural disasters with short-term communications, computer, and power solutions. Services include phone charging, internet & communications support, and lighting to disaster victims. MOVE also offers educational outreach.
In conjunction with the presence of the MOVE truck at the IEEE Global Humanitarian Technology Conference (GHTC), this is a panel discussion among representatives from organizations involved with emergency response and disaster recovery. The focus is on communications, computing, and power, but expanded from there. After a brief description of the MOVE truck, the emphasis is on stories about what works and lessons learned.

first few minutes: introduction about the Consultants’ Network of Silicon Valley (CNSV)
This event was organized by the Consultants‘ Network of Silicon Valley (CNSV) as part of its sponsorship of the GHTC, which was held September 8-11, 2022 at Santa Clara University.
Defcon 30, Black Hat, and BSides Las Vegas are all happening August 9-14 in Las Vegas! The Diana Initiative, too. Check out these links to read about “Hacker Summer Camp.” Great opportunities to keep up-to-date on cybersecurity and network.
A lot continues to happen in the cybersecurity field and here are a few things I think are worth highlighting, plus some notes on my current activities.
– federal Cybersecurity and Infrastructure Security Agency (CISA) (https://www.cisa.gov) continues to generate advice, including a series of insights at https://www.cisa.gov/insights
– I’m assisting a medical software startup with setting up its cybersecurity program for its Software as a Medical Device (SaMD) product.
– I’m doing program management work related to Public Key Infrastructure for a large Silicon Valley technology company. Lots to do to maintain compliance with WebTrust and CAB Forum requirements.
– RSA Conference (https://www.rsaconference.com/usa) and BSidesSF (https://bsidessf.org) in San Francisco are deferred from February to June 2022. I’ll probably volunteer again at BSidesSF, assuming it is reasonably safe with respect to COVID-19. Maybe hang out on the exhibit floor at RSA for a day.
This Spring and Summer there’s a lot going on relative to cybersecurity for medical devices. Check these out…
Defcon 30 Biohacking Village – is targeted for August 11-14 in Las Vegas. We’ll see whether that actually happens and how risky it may be to attend, depending on the status of COVID-19. https://www.villageb.io
It’s been a whirlwind week and it’s not over, yet. Defcon29 (aka “hacker summer camp”) was August 5-8 in Las Vegas. HIMSS21 (the Health Information Management Systems Society’s global conference) started August 9 and runs through August 13, also in Las Vegas. Temperatures have been as high as 108 degrees F. Both have been hybrid conferences with some online and some in person.
I volunteered with the Biohacking Village at Defcon29, which this year mainly involved monitoring the online discussion boards in case there was any inappropriate behavior. The in person things included villages regarding IoT Hacking, Car Hacking, Voting Machines, Cryptocurrency, Satellite Hacking, and a new group called Security Leaders. There were also some good sessions on Public Policy pertaining to cybersecurity.
I co-authored and co-presented a short talk at HIMSS21…
Cybersecurity in a Complex Healthcare Ecosystem David Snyder, 42TEK, Inc. & Mitch Parker, Indiana University Health
Managing cybersecurity risk for supply chains with multiple vendors is complicated. Each vendor is clearly responsible for its own system, but who minds the overall end-to-end concerns? These concerns affect both products, such as medical devices, and services, such as telehealth platforms. Healthcare delivery organizations can have over a thousand vendors, many of which connect to the organization’s network. Cybersecurity attackers can invade a supplier’s network, interrupt service, steal information, upload malware, and even get into the healthcare delivery organization’s network to do damage, install ransomware, or steal information. In this presentation, best practices were described for assessing risks, avoiding cybersecurity vulnerabilities, and for network-connected vendors and business partners to maintain security. Special attention was given to hospitals and remote patient monitoring. Containerization, Application Programming Interfaces, and modern virtualization techniques were also covered.
This talk was based on the paper posted elsewhere on this web site.
Key takeaways…
equally important with designing, implementing, and maintaining online systems securely is the need to anticipate and expect failures and malicious attacks that will require response and recovery. Sure, cyber defense, but plan for cyber resilience [recover quickly]. Offline backups, emergency contact lists, contingency plans, legal and technical consulting standby contracts, and table top practice session are essential.
there is a shortage of trained cybersecurity professionals, so start investing in training for your existing staff while continuing to seek the expertise you need
More and more RPM devices are being introduced for healthcare providers to use in managing post-acute and chronic care patients. The diagram below shows the variety of ways in which these devices may transmit information from the patient’s home to the clinician. Other posts on this site discuss cybersecurity relative to RPM.
This is a work in progress. Watch for updates to this post and the full article. (Last updated March 18, 2021)
Cybersecurity risk management for supply chains with multiple vendors is complicated. Each vendor is clearly responsible for its own system, but who minds the overall end-to-end concerns? This article asserts that coordination across organizational boundaries is needed to assess and mitigate cybersecurity risks in remote patient monitoring (RPM) systems.
Examples of network-connected RPM devices include wearables (e.g., smart watches), glucose monitors, pacemaker monitors, blood pressure cuffs, pulse oximeters, continuous positive airway pressure (CPAP) machines, scales, and more. Such devices are part of the family of the Internet of Things (IoT).
A 2019 survey of physicians showed “Two in three, or 68 percent, of physicians surveyed strongly intend to use remote patient monitoring technology…” However, the survey report also indicates “Health care professionals view data security as the main barrier to technology uptake.”[1]
The majority of recent cybersecurity analysis for medical devices has focused on devices used within hospitals and clinics. Cybersecurity for RPM is different in a number of ways.
RPM is a “system of systems” – a physical and digital chain consisting of devices connected to networks, connected to other networks. Typically, there are multiple stakeholders involved in the provision and operation of these systems These include device manufacturers that depend on a supply chain for software and hardware components, communications networks, data integrators, and the clinicians who are the ultimate users of the data (Figure 1). Also, various interfaces with humans, including patients, caregivers, developers, network engineers, and system administrators.
Figure 1
Attacks on healthcare delivery organization (HDO) networks via device or interim partner vulnerabilities are a bigger concern than attacks on individual devices. This is because more harm can be done if a healthcare delivery organization network is compromised. Attacks on these networks can not only result in theft of personally identifiable information, but also interruption of service, such as what occurs in a ransomware attack.
In a RPM digital supply chain with multiple vendors involved, it is necessary to take a “trust, but verify” approach. Clauses can be put in a contract or a “Business Associate Agreement” to require a supplier/partner (vendor) to maintain a good cybersecurity posture, but it is unlikely that the vendor can absolutely guarantee protection. When only written assurances of “best efforts” to prevent cybersecurity incidents are provided, it behooves the buyer/user to perform due diligence and monitor whether these efforts are effective.
One possible solution is for the healthcare delivery organization that is the receiver of the data to oversee the end-to-end process. Alternatively, the data platform vendor that consolidates, analyzes, and formats the data may be in a position to provide the needed coordination. On the other hand, it is difficult to imagine how device manufacturers could coordinate all of the stakeholders.
As a final thought, remember that the ever-changing cybersecurity landscape means it may not be possible to anticipate and mitigate all threats. In the event an incident occurs, there needs to be a plan to respond and recover. In an environment with multiple vendors, response coordination has to be planned and rehearsed before something happens. The objective is to make sure the entire remote patient monitoring system is resilient.
If you work for a health care delivery organization that is on the receiving end of a remote patient monitoring system, what are you doing to make sure all of the components in that system are secure and that you are ready to respond to problems?
If you are one of the vendors in remote patient monitoring system, what are you doing to make sure your upstream and downstream partners in the system are secure?
If you are not sure how to do this, you’ll probably want to obtain assistance to reach out to each of the organizations that comprise the end-to-end system and figure out an approach to make sure a holistic security framework is conceived and implemented.

November 14, 2019bydmsnyder in Uncategorized | Comments Off on Cybersecurity and the Future of Remote Patient Monitoring – December 10, 2019 Workshop in San Francisco
This 3-hour workshop on December 10, 2019 in San Francisco explored similarities and differences between network-connected medical devices in clinical settings versus residential environments, relative cybersecurity challenges, and best practices throughout the lifecycle of remote devices.
Several trends are driving increased interest and adoption for using network-connected medical devices outside the clinical environment to diagnose, monitor, and treat patients. These include an aging population living longer, often with multiple chronic illnesses, looming shortages of doctors and nurses, and incentives to reduce hospital readmissions.
“88% of health systems and hospitals surveyed have invested or plan to invest in remote patient monitoring solutions to support their organizational transitions to value-based care.” (Spyglass Consulting Group)
The FDA, hospitals, researchers, and device manufacturers have been working hard to define best practices for cybersecurity for network-connected medical devices in hospitals. Attend and see what you need to consider.
8-11 August 2019 – Las Vegas, Nevada Planet Hollywood
This is where hackers had a chance to explore medical devices to discover potential cybersecurity vulnerabilities and, hopefully, how to defend against them. Read more at
I volunteered at the Biohacking Village and was able to network with some excellent people about developing and maintaining network-connected medical devices securely. Ten medical device manufacturers provided approximately 40 devices for hackers to examine and explore. There were about 30 workshops, presentations, and panels, including some of the premier security researchers in this space and representatives from the FDA.
