What is the primary concern regarding the security of IoT devices?

  1. Lack of physical security

  2. Insufficient encryption

  3. Unpatched software

  4. All of the above


Correct Option: D
Explanation:

IoT devices often lack physical security measures, such as tamper-resistant enclosures, making them vulnerable to physical attacks. Additionally, insufficient encryption can expose sensitive data to eavesdropping, while unpatched software can provide attackers with an entry point to compromise the device.

Which of the following is NOT a common type of IoT attack?

  1. DDoS attack

  2. Man-in-the-middle attack

  3. Phishing attack

  4. SQL injection attack


Correct Option: D
Explanation:

SQL injection attacks are typically used to target web applications, not IoT devices. DDoS attacks, man-in-the-middle attacks, and phishing attacks are all common types of IoT attacks.

What is the primary purpose of a firewall in an IoT network?

  1. To block unauthorized access to the network

  2. To detect and prevent malicious traffic

  3. To provide secure remote access to the network

  4. To monitor network traffic for suspicious activity


Correct Option: A
Explanation:

A firewall's primary purpose is to control incoming and outgoing network traffic, preventing unauthorized access to the network and protecting it from external threats.

Which of the following is NOT a best practice for securing IoT devices?

  1. Using strong passwords and regularly changing them

  2. Keeping software up to date with the latest patches

  3. Disabling unused services and ports

  4. Connecting IoT devices to a public Wi-Fi network


Correct Option: D
Explanation:

Connecting IoT devices to a public Wi-Fi network is a security risk, as it exposes them to potential eavesdropping and man-in-the-middle attacks. Strong passwords, regular software updates, and disabling unused services and ports are all good security practices for IoT devices.

What is the role of encryption in IoT security?

  1. To protect data in transit from eavesdropping

  2. To protect data at rest from unauthorized access

  3. To authenticate IoT devices and users

  4. All of the above


Correct Option: D
Explanation:

Encryption plays a crucial role in IoT security by protecting data in transit from eavesdropping, protecting data at rest from unauthorized access, and authenticating IoT devices and users.

Which of the following is NOT a common IoT security standard?

  1. ISO/IEC 27001

  2. IEC 62443

  3. NIST SP 800-171

  4. HIPAA


Correct Option: D
Explanation:

HIPAA (Health Insurance Portability and Accountability Act) is a healthcare-specific regulation in the United States, not an IoT security standard. ISO/IEC 27001, IEC 62443, and NIST SP 800-171 are all widely recognized IoT security standards.

What is the term used to describe the unauthorized access, use, disclosure, disruption, modification, or destruction of information in an IoT system?

  1. Cybersecurity breach

  2. IoT attack

  3. Data breach

  4. Information security incident


Correct Option: D
Explanation:

An information security incident is a general term used to describe any unauthorized access, use, disclosure, disruption, modification, or destruction of information in an IoT system or any other information system.

Which of the following is NOT a recommended security measure for IoT devices that collect and transmit sensitive data?

  1. Implementing end-to-end encryption

  2. Using strong passwords and regularly changing them

  3. Disabling unused services and ports

  4. Connecting IoT devices to a public Wi-Fi network


Correct Option: D
Explanation:

Connecting IoT devices to a public Wi-Fi network is a security risk, as it exposes them to potential eavesdropping and man-in-the-middle attacks. End-to-end encryption, strong passwords, and disabling unused services and ports are all recommended security measures for IoT devices that collect and transmit sensitive data.

What is the primary purpose of a security information and event management (SIEM) system in an IoT network?

  1. To collect and analyze security logs from IoT devices

  2. To detect and respond to security incidents in real-time

  3. To generate security reports and alerts

  4. All of the above


Correct Option: D
Explanation:

A SIEM system is a centralized platform that collects and analyzes security logs from IoT devices and other network components. It detects and responds to security incidents in real-time, generates security reports and alerts, and helps organizations comply with regulatory requirements.

Which of the following is NOT a common IoT security threat?

  1. Malware

  2. DDoS attacks

  3. Phishing attacks

  4. Zero-day exploits


Correct Option: D
Explanation:

Zero-day exploits are not specific to IoT devices and can target any system with a software vulnerability. Malware, DDoS attacks, and phishing attacks are all common IoT security threats.

What is the term used to describe the process of identifying, assessing, and mitigating risks in an IoT system?

  1. Risk assessment

  2. Vulnerability assessment

  3. Threat assessment

  4. Security audit


Correct Option: A
Explanation:

Risk assessment is the process of identifying, assessing, and mitigating risks in an IoT system. It involves identifying potential threats and vulnerabilities, evaluating the likelihood and impact of these threats, and implementing appropriate security measures to mitigate the risks.

Which of the following is NOT a recommended security measure for IoT devices that are used in critical infrastructure?

  1. Implementing multi-factor authentication

  2. Using strong passwords and regularly changing them

  3. Disabling unused services and ports

  4. Connecting IoT devices to a public Wi-Fi network


Correct Option: D
Explanation:

Connecting IoT devices to a public Wi-Fi network is a security risk, as it exposes them to potential eavesdropping and man-in-the-middle attacks. Multi-factor authentication, strong passwords, and disabling unused services and ports are all recommended security measures for IoT devices that are used in critical infrastructure.

What is the term used to describe the unauthorized modification of data in an IoT system?

  1. Data tampering

  2. Data manipulation

  3. Data alteration

  4. Data corruption


Correct Option: A
Explanation:

Data tampering is the unauthorized modification of data in an IoT system. It can be done for various reasons, such as to gain unauthorized access to the system, to disrupt the system's operation, or to steal sensitive information.

Which of the following is NOT a common type of IoT botnet?

  1. Mirai

  2. Hajime

  3. WannaCry

  4. DDoS botnet


Correct Option: C
Explanation:

WannaCry is a ransomware attack that targeted computers running Microsoft Windows, not an IoT botnet. Mirai, Hajime, and DDoS botnets are all common types of IoT botnets.

What is the term used to describe the process of securing an IoT system by implementing various security measures?

  1. IoT security hardening

  2. IoT security configuration

  3. IoT security patching

  4. IoT security monitoring


Correct Option: A
Explanation:

IoT security hardening is the process of securing an IoT system by implementing various security measures, such as strong passwords, encryption, and disabling unused services and ports.
