4. Introduction
IoT is a network of physical objects that are embedded with
software, electronics, network and sensors that allows these
objects to collect and exchange data.
IoT is a unique features of IoT devices, network and applications,
which are quite different with smart phones and computers.
Hardware, software and connectivity will all need to be secure for
IoT objects to work effectively.
Without security for IoT, any connected object, from refrigerators
to manufacturing bots, can be hacked.
Once hackers gain control, they can usurp the object's
functionality and steal the user's digital data.

5. Methodology
IoT Features
Interdependence
Constrained
Unattended
Mobile
Ubiquitous
Intimacy
Diversity
Myriad

6. Interdependence
As the evolution of IoT devices, the interactions between devices become
more complex and human involvement is needless.
For example, if the thermometer detects the indoor temperature exceeds
the threshold and smart plug detects the air conditioner is in the OFF state,
and then the windows will automatically open.

7. Constrained
With the limitation of cost and physical conditions, many IoT devices,
especially industrial sensor and implantable medical devices, have been
designed to be light weight and small.
For example, lightweight IoT devices do not have the memory management
unit (MMU), so memory isolation, address space layout randomization (ASLR)
and other memory safety measures cannot be applied to these devices.

To enhance system security for constrained IoT devices, previous studies
focus on designing system security mechanisms for lightweight devices, but
most of them still cannot satisfy both the security and application
requirements.

8. Unattended
Unattended bots execute tasks and interact with applications
independent of human involvement.
As increasing adoption of wireless networking prompts, these
devices are evolving into IoT devices. We describe the long-time
unattended status of IoT devices as an IoT feature named
“unattended” here.
It is hard to physically connect an external interface to verify the
state of these devices. Thus, the remote attacks targeted them are
difficult to detect.

9. Mobile
Many IoT devices, such as wearable devices and
smart cars are used in the mobile environment.
For example, when user drives a smart car from one
district to another, the car can automatically collect
road information for highway foundational facilities in
the new district. It will become more common in the
future.
Because mobile IoT devices usually join more
networks, attackers tend to inject the malicious code
into mobile IoT devices to accelerate its spread.

10. Ubiquitous

Manufacturers
Operators
Researches

11. Intimacy
We describe the intimate relationship between users and IoT devices as an
IoT feature named “Intimacy” here.
These devices not only collect our biology information including heart rate
and blood pressure but also monitor and record our surrounding information
and daily activities like the change of indoor temperature and the locations
you have been.
The intimate relationships between users and IoT devices will certainly raise
more serious and unnoticed privacy concerns.
Driven by profit, these providers usually keep this data forever and even
share these data with other advertising agency without the user’s consent,
which increases the risk of privacy leak.

12. Myriad
We describe the enormous number of IoT devices and
the huge amount of IoT data as an IoT feature named
“Myriad” here.
In 2016, the attack traffic of Mirai botnet which was
composed of more than 1 million IoT devices, exceeded
1Tbps, which previous cyber-attacks have never been
achieved.
