Institutional considerations for managing risk around IoT

sockets for vendor products & services

There are a number of things to think about when planning and deploying an IoT system in your institution. In posts here since last spring, several issues have been touched upon — the idea of sockets and seams in vendor relationships, the rapid growth in vendor relationships to be managed and the resulting costs to your organization, communicating IoT risk, some quick risk visualization techniques based on Shodan data, initial categorization of IoT systems, and others.  The FBI warning on IoT last week is a further reminder of what we’re up against.

There is a lot to chew on and digest in this rapidly changing IoT ecosystem. Below is a partial list of some things to consider when planning and deploying IoT systems and devices in your institution. It’s not a checklist where all work is done when the checking is complete. Rather, it is intended to be a starting list of potential talking points that you can have with your team and your potential IoT vendors.

Some IoT Planning Considerations

  • Does IoT vendor need 1 (or more) data feeds/data sharing from your organization?
    • Are the data feeds well-defined?
    • Do they exist already?
    • If not, who will create & support them?
    • Are there privacy considerations?
  • How many endpoint devices will be installed?
    • Is there a patch plan?
    • Do you do the patching?
    • Who manages the plan, you or the vendor?
  • Does this vendor’s system have dependencies on other systems?
  • How many IoT systems are you already managing?
    • How many endpoints do you already have?
    • Are you anticipating/planning or planning more in the next 18 months?
  • Is there a commissioning plan? Or have IoT vendor deliverable expectations otherwise been stated (contract, memorandum of understanding, letter, other?)
    • Has the vendor changed default logins and passwords? Has the password schema been shared with you?
    • Are non-required ports closed on all your deployed IoT endpoints?
    • Has the vendor port scanned (or similar) all deployed IoT endpoints after installation?
    • Is there a plan (for you or vendor) to periodically spot check configuration of endpoint devices?
  • Has the installed system been documented?
    • Is there (at least) a simple architecture diagram?
      • Server configuration documented?
      • Endpoint IP addresses & ports indicated?
  • Who pays for the vendor’s system requirements (eg hardware, supporting software, networking, etc?)
    • Does local support (staffing/FTE) exist to support the installation? Is it available? Will it remain available?
    • If supporting IoT servers are hosted in a data center, who pays those costs?
      • startup & ongoing costs?
    • Same for cloud — if hosted in cloud, who pays those costs?
      • startup & ongoing costs?
  • What is total operational cost after installation?
    • licensing costs
    • support contract costs
    • hosting requirements costs
    • business resiliency requirements costs
      • eg redundancy, recovery, etc for OS, databases, apps
  • How can the vendor demonstrate contract performance?
    • Okay to ask vendor to help you figure this out
  • Who in your organization will manage the vendor contract for vendor performance?
    • Without person/team to do this, the contract won’t get managed
  • Can vendor maintenance contract offset local IT support shortages?
    • If not, then this might not be the deal you want
  • For remote support, how does vendor safeguard login & account information?
    • Do they have a company policy or Standard Operating Procedure that they can share with you?
  • Is a risk sharing agreement in place between you and the vendor?
    • Who is liable for what?

Typically, with the resources at hand, it will be difficult to get through all of these — maybe even some of these. The important thing, though, is to get through what we can and then be aware of and acknowledge the ones we weren’t able to do. It’s way better to know we’ve come up short given limited resources than to think we’ve covered everything when we’re not even in the ballpark.

Systems in the seam — shortcomings in IoT system implementation

Coming apart at the seams

One of the greatest areas of risk related to the Internet of Things (IoT) in an organization, corporation, or institution comes not necessarily from the IoT systems themselves, but rather the implementation of the IoT systems. A seam forms between the delivery of the system by the vendor/provider and the use of that system by the customer.  Seams, in themselves, are not bad. In fact, they’re essential for complex systems. They connect and integrate different parts of a system to work towards a cohesive whole.  However, how we choose to approach and manage these seams makes a difference.

Managing the seam

Seams are where interesting things happen. College baseball changed its ball seams this year to flat instead of raised to drive more hits and home runs and, sure enough, balls are traveling an average of 20 feet further.  There are seam routes in football where the receiver tries to exploit the gap between defenders. And anyone that’s ever sat in the window seat by the wing of an airplane can attest that there are many more seams than they would probably care to see. Finally, of course, seams can also be where things come apart.

More seams than I would care to be aware of

More seams than we would probably care to acknowledge

Vendor relationships and vendor management have always been important for firms and institutions. However, the invasive nature of IoT systems makes vendor management particularly important to successful IoT system implementation and subsequent operation. However, the work and staffing required to manage those customer-vendor relationships and to provide the oversight needed to operate safe and effective systems often gets obfuscated by the promises and shininess of the new technology.

IoT systems are different from traditional deployments of workstations, laptops, and servers. By their very nature, IoT systems have the ability to sense, record, transmit, and/or interact with the environments in which we live and work. Further complicating the IoT systems deployments and support, these systems may well be invisible to us and organizational IT might not even know the systems exist much less be able to provide central IT support.

Firms and institutions purchase IoT devices and systems en masse to address some need in their operation. These IoT systems might be related to environmental control and energy efficiency, safety of staff and the public (fire, security, other), biometric authentication systems, surveillance systems and others. Because of this, IoT devices can be brought into an organization’s physical and cyber space by the hundreds or thousands or more. When such systems and devices are partially or improperly configured, there can be significant consequences to the organization. Similarly, a lack of planning of long-term support, whether local or via maintenance contract with the vendor or both, can also have significant implications.

Cost of building a socket

In most organizations, implementing a third-party solution, whether hardware, software, SaaS, or hybrid, requires a supporting infrastructure for that solution. I call this supporting structure a socket. The customer organization must create a socket that allows the new vendor solution to interface with appropriate parts of the customer’s existing infrastructure. Taking the time and resources to plan, build, and maintain this socket is integral to the operational success of the new system. It also provides the opportunity to manage some of the risk that the new system introduces to the organization.

Know yourself

One of the worst case scenarios for an organization is believing that an IoT system is managed when it is actually not managed. At this point in the evolution of IoT deployments, I suspect that this scenario is more of the rule than the exception. Given the scale and speed of IoT innovation and growth and the lack of precedence for managing this sort of risk, the famed Sun Tzu guidance to know yourself can be elusive.  The IoT phenomena will change how we seek to know and characterize our organizations as a part of the risk management process.  A good place to start knowing ourselves is planning, building, and managing that seam where the interesting things happen.
