Bob has secretly installed smart CCTV devices (loT devices) outside his home and wants to access the recorded data from a remote location. These smart CCTV devices send sensed data to an intermediate device that carries out pre-processing of data online before transmitting it to the cloud for storage and analysis. The analyzed data is then sent to Bob for initiating actions.

Identify the component of loT architecture that collects data from loT devices and performs data pre-processing.

Kevin, a security team member, was instructed to share a policy document with the employees. As it was supposed to be shared within the network, he used a simple algorithm to encrypt the document that just rearranges the same characters to produce the ciphertext.

Identify the type of cipher employed by Kevin in the above scenario.

George, a professional hacker, targeted a bank employee and tried to crack his password while he was attempting to log on to the remote server to perform his regular banking operations. In thisprocess, George used sniffing tools to capture the password pairwise master key (PMK) associated with the handshake authentication process. Then, using the PMK, he gained unauthorized access to the server to perform malicious activities.

Identify the encryption technology on which George performed password cracking.

Which of the following techniques is referred to as a messaging feature that originates from a server and enables the delivery of data or a message from an application to a mobile device without any explicit request from the user?

Which of the following techniques protects sensitive data by obscuring specific areas with random

characters or codes?

Identify the technique through which mobile application marketers utilize the user's location to gather sensitive data and know about users' offline activities from the location data.
