IoT Overview: Concepts & Drivers

4

What is IoT really?

• Despite the buzz, no single definition.
• Or agreed numbers, or categories, or taxonomies...
• Different emphasis on different aspects of the concept
• Functionally: The extension of network connectivity and

computing capability to a variety of objects, devices, sensors and everyday items allowing them to generate/exchange data, often with remote with data analytic/management capabilities.

• As Value: Data & what can be done with it.
• As a Vision: The realization of a ‘hyper-connected” world.
• This is why it matters.
• This is why it’s hard.

One view, from McKinsey Global Institute:

Computers, Networks, and “Things”

“Machine to Machine” (M2M) (~1970s +)

Internet of Things Beginnings

Carnegie Mellon Internet Coke Machine (1982, 1990) Trojan Room Coffee Pot (first webcam) (1991) Internet Toaster (1990)

Key IoT Challenges

Security

12

Security Must be a Fundamental Priority

• Security information technology is not new, but IoT presents different

challenges

• Growth in devices increases the surface available for cyberattack
• Poorly secured devices affect the security of the Internet and other devices

globally, not just locally.

• Not just data at stake; Vulnerable devices interacting with the physical

world could present risk to property and life Developers and users of IoT devices and systems have a collective obligation to ensure they do not expose others and the Internet itself to potential harm.

13

A Spectrum of Unique IoT Device Security Challenges

See also IETF RFC 7452 Architectural Considerations in Smart Object Networking

• Cost/Size/Functionality
• Volume of Identical Devices
• Deployment at Mass Scale
• Long Service Life
• No / Limited Upgradability
• Limited Visibility into Internal

Workings

• Embedded Devices
• Physical Security Vulnerabilities
• Unintended Use
• BYOIoT

Internet connectivity as the next product “value add”

Recent IoT-Related DDoS Attacks

Date Target Size

20 September KrebsOnSecurity (Security Blog) ~660 Gbps 20 September OVH

(French Hosting Provider)

~1 Tbps 21 October DYN

(DNS Managed Services)

~1.2 Tbps

• All Linked to the Mirai malware which uses IoT devices as Bots
• Mirai source code released on hacking websites in October

15

Krebs DDoS attack data

From CloudFlare POV & Analysis of KOSA:

• Several waves of the attack
• Largest attack originated from bots on

737 Networks

• Some 128,833 unique IP addresses

Location of top source ASN’s (wave 3):

It’s not about where you are, it’s about what’s exploitable on your network!

What vulnerabilities does Mirai exploit?

• Human behaviour!
• Scans the Internet

for IoT devices that have not changed factory username and password defaults

• 68+ username and

password pairs in Mirai’s source code.

The Good News: Internet Resiliency and Collaborative Security in Action

• The Internet did not “go down”
• Website & service disruptions but

functionality restored relatively swiftly

• Collaboration and collective action

across companies to stem the attacks

• Widespread information sharing
• Collaboration between private sector

and government

• Multistakeholder dialouges
• Key Action Points:
• Good design practices
• Data confidentiality, authentication, and

access control

• Field upgradability
• Device obsolescence
• Standards and metrics
• Consumer awareness
• Penalties for irresponsible actors?

Privacy

21

Privacy and IoT: Data is a Double-Edged Sword

• The data streams /analytics that drive the value IoT can also paint very detailed

and intrusive pictures of our lives.

• Expands the feasibility / reach of surveillance and tracking
• Redefining the debate about privacy issues
• Can dramatically change the ways personal data is collected, analyzed,

used and protected.

• Implications on our:
• Basic rights
• Sense of personal safety and control
• Ability to trust the Internet and devices connected to it.

22

Meaningful Awareness & Control Breakdown of “Notice and Consent” Managing Across Many Devices

Different Dimensions of Privacy Challenges in IoT

Individual Preferences in Common Contexts Aggregation of Personal / Behavioral Data

Cross-Border Data Flows Global Data Protection Discrimination Law Enforcement

23

Enhancing Privacy in IoT

• Strategies need to be developed that respect individual privacy choices across a

broad spectrum of expectations, while still fostering innovation in new technology and services.

• Traditional on-line privacy models may not fit.
• Adapting/adopting basic privacy principles, such as:
• Transparency/Openness
• Meaningful Choice
• Data Minimization
• Use Limitation
• Among others..

24

Interoperability & Standards

25

I&S: Not Just a Tech Challenge, It’s a Market Issue

Overall

• N. America

Europe Source: World Economic Forum

40% Interoperability is necessary to create up to

40 percent of the economic value generated by IoT

• - McKinsey Global Institute

Efficiency Scale Market Value

26

Interoperability / Standards Considerations

• Complex / Dynamic Service Delivery Chains and Use Cases
• Land Rush and Schedule Risk
• Proliferation of Standards Efforts
• Industry coalitions, alliances, SDOs, proprietary development etc.
• Where is Interoperability Needed?
• Reusable Building Blocks
• Best Practices and Reference Models

Ultimately about advancing innovation and user choice

27

Closing Thoughts

• IoT is happening now, with tremendous transformational

potential

• May change the way we think about what it means to

be “online”

• But the challenges must be addressed to realize the
• pportunities and benefits
• Significant. Real. But not insurmountable
• Solutions won’t found by simply pitting promise vs.

peril

• It will take Informed engagement, dialogue, and collaboration across a

range of stakeholders to find solutions and to plot the most effective ways forward.
