An loT sensor in an organization generated an emergency alarm indicating a security breach. The servers hosted in an loT layer accepted, stored, and processed the sensor data received from loT gateways and created dashboards for monitoring, analyzing, and implementing proactive decisions to tackle the issue. Which of the following layers in the loT architecture performed the above activities after receiving an alert from the loT sensor?
Correct Answer: B
In the Internet of Things (IoT) architecture, the Process layer is responsible for the activities described in the scenario. This layer employs IoT platforms to accumulate and manage all data streams, including accepting, storing, and processing sensor data received from IoT gateways1. It also involves creating dashboards for monitoring, analyzing, and implementing decisions based on the data received. The Process layer is a critical component of IoT architecture, as it provides the necessary computing power and data management capabilities required for the effective functioning of IoT systems. It ensures that data collected by sensors is processed in a way that actionable insights can be derived and appropriate responses can be implemented in case of events like security breaches1. The other options listed pertain to different aspects of IoT architecture: * A. Communication Layer: This layer is responsible for transferring data from devices to the network and vice versa but does not process or analyze the data. * C. Cloud Layer: While the cloud layer may be involved in data storage and processing, it is not the primary layer responsible for the activities mentioned. * D. Device Layer: This layer includes the physical devices and sensors that collect data but does not process or analyze it. Therefore, the correct answer is B, the Process layer, as it aligns with the responsibilities of managing and processing data within the IoT architecture.
ECSS Exam Question 2
Which of the following layers of the loT architecture is responsible for delivering services to respective users from different sectors such as building, industrial, manufacturing, automobile, security, and healthcare?
Correct Answer: C
The application layer in IoT architecture is responsible for delivering services to respective users from different sectors such as building, industrial, manufacturing, automobile, security, and healthcare. It provides the user interfaces and applications that interact with IoT devices and systems. References: EC-Council Certified Security Specialist (E|CSS) documents and study guide1.
ECSS Exam Question 3
William is an attacker who is attempting to hack Bluetooth-enabled devices at public places. Within the target's range, he used special software to obtain the data stored in the victim's device. He used a technique that exploits the vulnerability in the OBject Exchange (OBEX) protocol that Bluetooth uses to exchange information. Identify the attack performed by William in the above scenario.
Correct Answer: B
William performed the Bluesnarfing attack. Bluesnarfing is a technique where an attacker exploits a vulnerability in the OBject Exchange (OBEX) protocol used by Bluetooth to exchange information. By doing so, the attacker gains unauthorized access to data stored on the victim's Bluetooth-enabled device.

ECSS Exam Question 4
Jessica, a user, wanted to access the Internet from her laptop and therefore sends a connection request to the access point. To identify the wireless client, the access point forwarded that request to a RADIUS server. The RADIUS server transmitted authentication keys to both the access point and Jessica's laptop. This key helps the access point identify a particular wireless client. Identify the authentication method demonstrated in the above scenario.
Correct Answer: D
The scenario described involves the use of a RADIUS (Remote Authentication Dial-In User Service) server. RADIUS is a client-server protocol that provides centralized network authentication12. In this case, the access point (client) forwards the connection request to the RADIUS server, which then sends authentication keys to both the access point and the user's laptop (supplicant). This process helps the access point identify the wireless client12. RADIUS servers are also known as AAA (Authentication, Authorization, and Accounting) servers because they provide these three services1. The authentication process begins when a user attempts to log into the network. Their device will request access either through the use of credentials or by presenting an X.509 digital certificate1. The RADIUS server then compares the user's information with a list of users stored in a directory or IDP (Identity Provider)1. Therefore, the authentication method demonstrated in the scenario is centralized authentication (Option D), where a central server (in this case, the RADIUS server) handles the authentication of users.
ECSS Exam Question 5
Wesley, a fitness freak, purchased a new Apple smartwatch and synced it with a mobile app downloaded from an unauthorized third party. At the end of the day, when Wesley attempted to access his fitness report from the app, it generated an unusual report and asked for some unnecessary permissions to view it. Which of the following mobile risks is demonstrated in the above scenario?
Correct Answer: B
In this scenario, Wesley's use of an unauthorized third-party mobile app to sync with his Apple smartwatch highlights the risk of improper platform usage. Here's why: * Unauthorized Third-Party App: Wesley downloaded the app from an unauthorized source, which * means it hasn't undergone proper security checks or vetting. Such apps may contain vulnerabilities or malicious code. * Unusual Report and Unnecessary Permissions: The app generated an unusual fitness report and requested unnecessary permissions. This behavior indicates that the app is not following proper guidelines for platform usage. * Platform Security Guidelines: Mobile platforms (like iOS or Android) have specific guidelines for app development and usage. When users sideload apps from untrusted sources, they bypass these guidelines, risking security and privacy. * Risk Implications: * Data Privacy: Unauthorized apps may mishandle sensitive data (like fitness reports), leading to privacy breaches. * Malware or Spyware: The app could contain malicious code, potentially compromising the device or user data. * Permissions Abuse: Requesting unnecessary permissions can lead to data leakage or unauthorized access. References: * EC-Council Certified Security Specialist (E|CSS) documents and study guide provide insights into mobile security risks and best practices1. * EC-Council's focus on information security emphasizes the importance of proper platform usage and adherence to guidelines1.
