Q

IOT and Big Data Facts and Background

A

Big Data is a term used to describe the nearly ubiquitous collection of data about individuals from multitudinous sources, coupled with the low costs to store such data and the new data mining techniques used to draw connections and make predictions based on this collected information.

IOT: The data analyzed by analytics programs, algorithms, machine learning, and other data mining techniques—the underpinnings of the term Big Data—are often gathered by devices collectively known as IoT. The next evolution of interaction with computer devices combines sensors almost anywhere with connection to the Internet.

The number of sensors connected to the Internet is now counted in the tens of billions.

By 2025, it is estimated that amount of data will double every 12 hours.

Big Data is characterized by the “three Vs”: velocity (how fast the data is coming in), volume (the amount of data coming in), and variety (what different forms of data are being analyzed).

Microsoft’s CEO Satya Nadella proposed a list of AI design principles, including several that focus on privacy issues: “AI must be designed to help humanity, AI must be designed for intelligent privacy, AI must be transparent, and AI needs algorithmic accountability so humans can undo unintended harm.

Q

Friends and Family Test

A

would the managers feel comfortable if data on themselves and their family and friends were in the database, subject to possible breach? For instance, would managers at the bank feel comfortable with their own family’s data going into the ACF database? If not, that is a reason to take greater precautions from cybersecurity perspective.

Q

Direct and indirect identifiers

A

Direct identifiers = data that identify an individual with little or no additional effort.
Examples: address, phone number

Indirect identifiers = data such as age or gender that can increase the likelihood of identifying an individual.

Q

De-id terms: pseud, de-id, anon

A
  • Pseudonymous data: Information from which the direct identifiers have been eliminated. Indirect identifiers remain intact.
  • De-identified data: Direct and known indirect identifiers have been removed.
  • Anonymous data: Direct and indirect identifiers have been removed or technically manipulated to prevent re-identification.

These categories do not result from a single method or from reducing the identifiability of data. Instead, reduction of the risk of re-identification results from a collection of techniques that can be applied to different kinds of data with differing levels of effectiveness.

Q

Blurring

A

• Blurring. This technique reduces the precision of disclosed data to reduce the certainty of individual identification. For example, date of birth is highly identifying (because a small portion of people are born on a particular day of a particular year), but year of birth is less identifying. Similarly, a broader set of years (such as 1971-1980, or 1981-1990) is less identifying than year of birth.

Q

Masking

A

Masking. This technique masks the original values in a data set with the goal of data privacy protection. One way this may be accomplished is to use perturbation—make small changes to the data while maintaining overall averages—to make it more difficult to identify individuals.

Q

FTC Characterization of a Data Broker in 2014

A

The FTC characterized the data broker industry as: collecting consumer data from numerous sources, usually without consumers’ knowledge or consent; storing billions of data elements on nearly every U.S. consumer; analyzing data about consumers to draw inferences about them; and combining online and offline data to market to consumers online.

Q

FTC broad categories of products offered by data brokers - 2014

A

(1) marketing (such as appending data to customer information that a marketing company already has),
(2) risk mitigation (such as information that may reduce the risk of fraud) and
(3) location of individuals (such as identifying an individual from partial information).

For each of these segments of the industry, the FTC suggested that data brokers engage in data minimization practices, review collection practices carefully as they relate to children and teens, and take reasonable precautions to ensure that downstream users did not use the data for discriminatory or criminal purposes.

Q

Connected Cars

A
  • Examples:
    a vehicle that wirelessly alerts the dealership when tires need to be rotated.

app from a car insurance company that records braking habits.

  • Privacy experts raise concerns that these configurations place sensitive information at risk to unauthorized access or hacking. The complexity of these issues has led to a situation where numerous federal agencies are considering regulating connected cars: the National Highway Traffic Safety Administration (NHTSA), FTC, and the Federal Communications Commission (FCC).

Q

Smart Cities: DHS Report

A

Highlighted 3 themes in cyber risks that arise when integrating with city infrastructure:

  • Changing seams - btw legacy and new system, and urban and rural systems - boundaries disappearing
  • Inconsistent adoption
  • Increased automation
    can lead to more threat vectors, cascading failures, and removal of manual overrides.

Surveillance and big brother aspect comes into play with smart cities, bc are governmental led.

Q

Broadband Internet Technical Advisory Group reccs on IOT and privacy/security (2016)

A
  • IoT devices should follow security and encryption best practices
  • For devices that can be customized by the users, the company should test the IoT devices in different possible configurations
  • IoT devices should be designed to facilitate automated, secure software updates
  • IoT devices should be secured by default by the inclusion of a password
  • IoT devices should be shipped originally with reasonably up-to-date software
  • IoT devices should be shipped with a privacy policy that is understandable and easy to find
  • IoT devices should communicate with restrictive rather than permissive protocols
  • IoT devices should continue to function if Internet connectivity is disrupted or if cloud back-up fails

Note: Real risk from IOT is not individual device compromised, but that IOT will allow for network attack.

Q

FTC Report on IOT (2015) - Internet of Things: Privacy and Security in a Connected World

A
  • Volume and personal nature of data in IOT heightens the need for protection.

If no consumer interface, no choice available. So, consider choice at point of sale, video tutorials, choice during set up, dashboards and icons, email/text

Security risks identified:

  • lax security that could allow intruders access to personal information collected by the devices,
  • security vulnerabilities on a consumer’s device that could lead to attacks on networks connected to the device,
  • and security issues with the devices that could place physical safety at issue, such as changes to instructions for an insulin pump or to a lock on a front door to a house.

In response, FTC urged:

  • security by design
  • deploy seucrity
  • vendor management
  • security at several levels
  • access controls
  • monitor throughout lifecycle
