Computational Collective Intelligence) 1st
Edition .
Q1. Which of the following best characterizes the massive
attack surface created by IoT systems?
A) The attack surface is small because IoT devices are usually
isolated.
B) The attack surface is massive due to billions of connected
devices, many with weak default credentials and limited
security capabilities.
C) The attack surface only concerns government-owned devices.
D) The attack surface is negligible because IoT devices have
strong built-in security.
Answer: B
Rationale: As described in the textbook, IoT systems create an
,Page 2 of 147
extremely large attack surface because they consist of billions of
heterogeneous devices, many of which are deployed with
insecure default configurations and limited computational
resources for security.
Q2. A compromised IoT device can be used by attackers to:
A) Only collect environmental data.
B) Steal sensitive personal/business data, serve as an entry
point to internal networks, or be recruited into a botnet.
C) Only run legitimate software.
D) Only cause physical damage in a controlled manner.
Answer: B
Rationale: As noted in the book, compromised IoT devices can be
weaponized to steal sensitive information, provide access to
other network resources, and become part of large-scale botnets
that disrupt critical infrastructure.

Q3. Which of the following is NOT a consequence of failing to
secure IoT devices properly?
A) Operational disruptions.
B) Safety hazards in healthcare and transportation.
C) Guaranteed immunity from all cyberattacks.
D) Significant financial and legal penalties due to regulatory
non-compliance.
Answer: C
Rationale: The textbook highlights that insecure IoT devices lead
to operational disruptions, safety hazards, and financial/legal
penalties. No security measure guarantees immunity from all
attacks.
Q4. The connected nature of devices within the IoT has brought
both unprecedented opportunities and formidable challenges.
, Page 4 of 147
The primary cybersecurity challenge stems from:
A) The low cost of IoT devices.
B) The sheer scale, heterogeneity, and often
resource-constrained nature of IoT devices.
C) The absence of any wireless connectivity.
D) The fact that all IoT devices run the same operating system.
Answer: B
Rationale: The introduction of the textbook emphasizes that the
massive scale, variety of device types, and limited
processing/storage/power resources of many IoT devices create
unique security challenges.
Q5. According to the book, what is a key knowledge
gap that IoT Cybersecurity aims to address?
A) The lack of programming languages for IoT.
B) The significant gap between the rapid deployment of
