Recognizing the risks

15

▪ Risks well identified by developers ▪ Possible tension with

commercial requirements

Source: Eclipse Foundation & IEEE

Prioritising security

16

▪ Device creation pressures

• Prioritize ease-of-use and time-to-market over incorporation of security (and privacy) protection

Security Vulnerabilities

Cost contraints

Delivery limitations

Expertise Customer

behaviours

Operational constraints

Potential security consequences

17

▪ There are a number of costs associated with security risks • Customers lose privacy

▪ Cyber crime increases

• Private data such as bank and credit card information

▪ IoT expansion will extend this to health, location, surveillance, etc

• Compromised internet enabled devices ▪ Sending spam, spoof data, harvesting and using stolen

credentials and DoS attacks

• M2M activities with no human oversight

▪ Customers lose trust and take business elsewhere

Considerating Big Data Data is the new currency

• User data access may require value add from suppliers

Data security – sensitive data • Data transmission • Data retention

Regional variations Operational considerations

• Dependent upon solution Connectivity Latency Performance / battery

• Is it always appropriate?

18

Capture & analytics Verizon research indicates that only around 8% of companies are

using more than 25% of the data they capture The potential to analyse not just obvious data but related

information enables additional business intelligence to be generated • Supports machine learning • Greater customer insight • Trend analysis • May be your differentiating service!

19

Cloud vs. local

Some actions prompted by data need to be immediate

• Context is critical

Clean and/or encrypted information

20

Why is power management important?

21

When is power management important?

22

It should always should be considered a crucial feature • Alongside areas such

as security • Even if the scenario

doesn’t appear to require careful power management

• Not just for items such as wearables or smartphones

Identifying power saving opportunities

Need to identify all possible behaviors • Use-case modelling • Likely areas of compromise vs non-

negotiable behavior

Power mode flows • Including transitions from one-state to

another

Connectivity • Which protocol best suits usage? • Always-on?
