December 11-12, 2018 at the Hotel Kabuki in San Francisco.
On December 11th, I was joined by a great team to conduct a 2.5-hour workshop entitled “Cybersecurity for Medical Devices is a “Team Sport.” Assisting with the workshop were:
The workshop focused on how device developers can collaborate with hospitals and clinics to help make sure medical devices are set up and managed to protect patients’ privacy and safety.
The highly interactive session was conducted by a team with diverse backgrounds, including a hospital CIO, a clinical engineer, a hospital information security officer, and two neutral cybersecurity consultants to facilitate and moderate. Topics covered included:
Group exercises and case studies were included.
There are over 5,000 hospitals in the U.S. and I’ve seen the number 6,000 as the number of medical device manufacturers. Medical devices are increasingly built with network connectivity. Examples include heart monitors, infusion pumps, glucose monitors, and assorted other treatment and diagnostic devices.
Cybersecurity has traditionally been concerned with Confidentiality, Availability, and Integrity of data. However, in medical devices and critical infrastructure (such as the electric power grid), the potential for harm means we have to include Safety when we think about cybersecurity.
On December 11, 2018, I’ll be leading the INTERACTIVE WORKSHOP: Cybersecurity For Medical Devices Is A “Team Sport” at the Connected Devices: Cybersecurity & Compliance Summit in San Francisco at the Kabuki Hotel. See http://connected-devices-summit.com. This interactive workshop will focus on how device developers can collaborate with hospitals and clinics, who purchase network-connected medical devices and need to operate them in their complex networks. This highly interactive and hands-on session will be conducted by a team with diverse backgrounds, including a hospital CIO, a clinical engineer, a hospital information security officer, and two neutral cybersecurity consultants to facilitate and moderate.
My collaborators for this workshop include:

The Symposium on Securing The Internet of Things (http://securingthenet.com) took a deep dive on what it will take to protect the billions of devices on which we depend for critical infrastructure, healthcare, and our homes. I led a panel discussion on Security for Network-Connected Medical Devices.
The event was March 5 – 7, 2018 at the Crowne Plaza Hotel in Burlingame, CA (near San Francisco Airport). [See agenda at https://42tek.com/STIOTAGENDArev6.pdf] 
My session addressed security topics in medical device design and manufacturing, usage in hospitals, remote monitoring, and related legislative, regulatory, and standards initiatives. Bill Saltzstein of Code Blue Communications, Peyton Paulick Kochel, Ph.D. of Proteus Digital Health, and Eric Pancoast of Medcrypt participated in the panel and May Wang of Zingbox gave a keynote presentation.

Did you know that Northeastern University has a Silicon Valley campus? Not only that, but they offer a 13-week course on the Internet of Things (http://info.leveledu.com/iot). I’m just wrapping up the capstone project for the class. Among other things, we did some interesting work with small sensors and some Arduino devices, worked with networks and Raspberry Pi devices, and explored Fog Computing. My capstone project involves a sensor to detect when a collection box is full. Of course, one of my main interests in this is how to design and maintain security for Internet-connected devices.

“$700 Billion Senate Defense Bill Calls for Blockchain Cybersecurity Study”
https://www.coindesk.com/700-billion-senate-defense-bill-calls-blockchain-cybersecurity-study/
“A $700 billion defense bill passed by the US Senate includes a mandate for a blockchain study to be conducted by the Department of Defense.”
“Yesterday, the US Senate passed a massive defense spending package that provides hundreds of billions of dollars to the US military. Public records show that an amendment included in that bill, proposed by Senator Rob Portman of Ohio, would “require a report on cyber applications of blockchain technology” if signed into law.”
Perhaps a good idea, but probably deserves some discussion.
The amendment specifically calls for
“…a report on the potential offensive and defensive cyber applications of blockchain technology and other distributed database technologies and an assessment of efforts by foreign powers, extremist organizations, and criminal networks to utilize these technologies. Such report shall also include an assessment of the use or planned use of blockchain technologies by the United States Government or critical infrastructure networks and the vulnerabilities of such networks to cyber attacks.”
For one thing, I would recommend deleting the option for the report to be submitted in classified form, while possibly still allowing it to be submitted “…in unclassified form with a classified annex.” I hope people will discuss this, or at least get the issue into the legislative history, before this goes through. It would be a shame to spend taxpayer dollars for such a study, only to have it buried as a classified document.
Here’s an excerpt from the Sept 18, 2017 version of the proposed amendment to the National Defense Authorization Act for Fiscal Year 2018:
https://www.congress.gov/amendment/115th-congress/senate-amendment/1055/text
AMENDMENT NO. 1055
(Purpose: To require a report on cyber applications of blockchain technology)
At the end of subtitle C of title XVI, add the following:
SEC. 1630C. REPORT ON CYBER APPLICATIONS OF BLOCKCHAIN
TECHNOLOGY.
(a) Report Required.–Not later than 180 days after the date of the enactment of this Act, the Secretary of Defense, in consultation with the heads of such other agencies and departments as the Secretary considers appropriate, shall submit to the appropriate committees of Congress a report on the potential offensive and defensive cyber applications of blockchain technology and other distributed database technologies and an assessment of efforts by foreign powers, extremist organizations, and criminal networks to utilize these technologies. Such report shall also include an assessment of the use or planned use of blockchain technologies by the United States Government or critical infrastructure networks and the vulnerabilities of such networks to cyber attacks.
(b) Form of Report.–The report required by (a) may be submitted–
(1) in classified form; or
(2) in unclassified form with a classified annex.
(c) Appropriate Committees of Congress Defined.–In this section, the term “appropriate committees of Congress” means–
[[Page S5795]]
(1) the Committee on Armed Services, the Select Committee on Intelligence, and the Committee on Homeland Security and Governmental Affairs of the Senate; and
(2) Committee on Armed Services, the Permanent Select Committee on Intelligence, and the Committee on Homeland Security of the House of Representatives.
The Equifax data breach is another wake-up call regarding the security of personal information. Perhaps it will add impetus to the idea of enhancing ways for individuals to safeguard their personal information that is stored by institutions. Maybe some of the ideas for using blockchain technology will be helpful.
SC Magazine published an article detailing what is thought to have occurred in the Equifax breach: “Apache Struts vulnerability likely behind Equifax breach, Congress launches probes.” (https://www.scmagazine.com/apache-struts-vulnerability-likely-behind-equifax-breach-congress-launches-probes/article/687955/) The author notes,
“The incident could also ‘have wide-reaching implications for how Americans identify themselves in the future, such as when applying for banking and credit services – simply knowing a name, date of birth, address and Social Security number shouldn’t ever be enough,’ says [Alex] Smith. ‘This breach could finally be the security wakeup call the US needs to widely adopt digital identity tokens, and potentially a digital national identity scheme similar to other countries such as Belgium.’” [see “The Belgian Electronic Identity Card (Overview)” https://www.esat.kuleuven.be/cosic/publications/article-769.pdf]
There are two reasons why a national digital identity scheme may be a long time coming in the US. First, it would run into conflicts with our having 50 states and other jurisdictions like the District of Columbia, Puerto Rico, and Guam, each issuing identity credentials, such as driver’s licenses. Second, we have a history of shunning national identification (paradoxically for fear of privacy concerns), as evidenced by Congress specifically saying that no federal funds shall be spent on a national health identification number (see PUBLIC LAW 105–277—OCT. 21, 1998, “None of the funds made available in this Act may be used to promulgate or adopt any final standard under section 1173(b) of the Social Security Act (42 U.S.C. 1320d–2(b)) providing for, or providing for the assignment of, a unique health identifier for an individual (except in an individual’s capacity as an employer or a health care provider), until legislation is enacted specifically approving the standard.”).
Given these national obstacles to updating how identity is managed in the US, it seems we may have to rely on the marketplace to come up with solutions, instead of waiting for government to take the lead. I expect we’ll see some Congressional hearings as a result of the Equifax breach, but probably no meaningful legislation.
One possibility for marketplace activity is for institutions that rely on identity, such as banks, insurers, and so on, to adopt blockchain technology. Earlier this year, there was an article in Forbes on this: “How The Blockchain Will Secure Your Online Identity” (https://www.forbes.com/sites/jonathanchester/2017/03/03/how-the-blockchain-will-secure-your-online-identity/#e9d4bda55234).
I can imagine organizations making it a selling point to be able to provide customers with apps that allow them to control who and when their information can be accessed.
The idea is not new. It is discussed in “How GDPR plus blockchain leads to the future of self-sovereign identity” (http://www.janrain.com/how-gdpr-plus-blockchain-leads-to-the-future-of-self-sovereign-identity/). This article references a 2015 paper that concludes, “Personal data, and sensitive data in general, should not be trusted in the hands of third-parties, where they are susceptible to attacks and misuse. Instead, users should own and control their data without compromising security or limiting companies’ and authorities’ ability to provide personalized services.” (“Decentralizing Privacy: Using Blockchain to Protect Personal Data” http://web.media.mit.edu/~guyzys/data/ZNP15.pdf)
[Update 9/15/17: “Equifax has confirmed that attackers entered its system in mid-May through a web-application vulnerability that had a patch available in March.” (https://www.wired.com/story/equifax-breach-no-excuse/) and “Equifax (EFX) says its chief information officer and chief security officer are leaving the company…” (https://www.cbsnews.com/news/2-equifax-executives-exit-after-massive-data-breach/).

I’ve long been concerned with the quality of data generated by field sampling and remote monitoring programs. First in environmental investigations — then in healthcare.
Internet-connected devices need to be designed to ensure that the data they provide is sufficiently reliable for its intended use, such as big data analytics.
“Gartner, Inc. forecasts that 6.4 billion connected things will be in use worldwide in 2016, up 30 percent from 2015, and will reach 20.8 billion by 2020. In 2016, 5.5 million new things will get connected every day.” (http://www.gartner.com/newsroom/id/3165317).
Many of these “Internet of Things” (IoT) devices contain sensors that will collectively generate petabytes of data and there has been much discussion of so-called “Big Data” analytics for managing and making sense of this data. Most of these big data discussions seem to assume that the data is good. The phrase “garbage in/garbage out” is fairly well known, but there does not seem to be much discussion of its importance for data analytics. Decisions based on poor data may yield the wrong results.
Key considerations to make sure that good data is used include the provenance of the data and its quality. That is, reliable knowledge about the source of the data (provenance) and an appropriate level of certainty about the timeliness and correctness of the data (quality). In this context, “correctness” means that the data is sufficiently accurate, precise, and specific. Correctness also means that the data is appropriate for its intended use.
Data users depend on an appropriate level of security for the data. This includes data at rest (in storage), data in motion (being transmitted), and data in use (being analyzed). Security is not just about confidentiality, but includes integrity (not corrupted or deleted), availability (able to be accessed when desired), and non-repudiation (once established, cannot be revoked or denied). Remote patient monitoring devices and environmental sensors are examples where high assurance regarding provenance, quality, and security can be important.
Until recently, more attention has been given to confidentiality than to integrity and availability. Thousands of articles have been written about preventing hackers from stealing information. Additionally, consciousness about security for Internet-connected devices has been raised due to the role of Internet-connected devices in recent Distributed Denial of Service (DDoS) attacks on web sites and Domain Names Services (DNS). While these are important issues to address, going forward, industry and government need to pay more attention to also ensuring these Internet-connected devices are producing high quality data and that the source of the data is adequately identified, so that consumers of such data can have confidence in what they are receiving.
Besides Internet-connected devices collecting and reporting data, other connected devices are used for executing actions, such as opening and closing valves. Some of these devices operate autonomously or semi-autonomously using data delivered via local, wide-area, or cloud networks to trigger actions. For example, local or remote sensors that trigger controls to shut down an overheating machine or shut it down when other conditions make it necessary.
Similar to remote data sensing devices, remotely-triggered devices need to have confidence regarding data provenance, quality, and security. In other words, confidence that information or commands are coming from an authorized and trusted source, that the information is correct, and that the system has not been compromised.
During the design, development, and implementation of IoT devices and associated structures, a systematic approach is needed to ensure that data provenance, quality, and security are adequately addressed. It is not sufficient to conduct security reviews after products have already been developed. Strategies and tactics are needed to (i) establish appropriate levels for provenance, quality, and security, (ii) ensure they are implemented and maintained, and then (iii) monitor compliance. Ideally, these will be expressed in a set of best practices for the design, manufacture, and implementation of Internet-connected devices.
Additional notes:
Blockchain technology, which is the underlying technology supporting Bitcoin and other cryptocurrencies, is starting to be used to address the issues of Provenance. Distributed ledgers built with blockchain technology provide a trusted, immutable, time-stamped record of transactions or assets.
