George, a certified security professional, was hired by an organization to ensure that the server accurately responds to customer requests. In this process, George employed a security solution to monitor the network traffic toward the server. While monitoring the traffic, he identified attack signatures such as SYN flood and ping of death attempts on the server.

Below are the various steps involved in establishing a network connection using the shared key

authentication process.

1.The AP sends a challenge text to the station.

2.The station connects to the network.

3.The station encrypts the challenge text using its configured 128-bit key and sends the encrypted text to the AP.

4.The station sends an authentication frame to the AP.

5.The AP uses its configured WEP key to decrypt the encrypted text and compares it with the original challenge text.

What is the correct sequence of steps involved in establishing a network connection using the shared key authentication process?

Joseph, a cloud administrator, was recruited for the management and deployment of the software

containers. As part of his job, Joseph employed an automated solution that converts images into containers, deploys them to the hosts, and further monitors container workflow from a single location.

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.

Bob, a security professional, was recruited by an organization to ensure that application services are being delivered as expected without any delay. To achieve this, Bob decided to maintain different backup servers for the same resources so that if one backup system fails, another will serve the purpose.

Identify the IA principle employed by Bob in the above scenario.

Which of the following IDS components analyzes the traffic and reports if any suspicious activity is

detected?

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?

Identify the loT communication model that serves as an analyzer for a company to track monthly or yearly energy consumption. Using this analysis, companies can reduce the expenditure on energy.
