Identify a machine in the network with 5SH service enabled. Initiate an SSH Connection to the machine, find the file, ttag.txt. in the machine, and enter the tile's content as the answer. The credentials tor SSH login are sam/adm(admin@123. {Practical Question)
Correct Answer:
D
bob1@sam is the file’s content as the answer. To find the machine with SSH service enabled, one can use a network scanning tool such as Nmap to scan the network for port 22, which is the default port for SSH. For example, the command nmap -p 22 192.168.0.0/24 will scan the network range 192.168.0.0/24 for port 22 and display the results2. To initiate an SSH connection to the machine, one can use a command-line tool such as ssh or an SSH client such as PuTTY to connect to the machine using the credentials sam/admin@123. For example, the command ssh sam@192.168.0.10 will connect to the machine with IP address 192.168.0.10 using the username sam and prompt for the password admin@1233. To find the file flag.txt in the machine, one can use a file searching tool such as find or locate to search for the file name in the machine’s file system. For example, the command find / -name flag.txt will search for the file flag.txt from the root directory (/) and display its location4. To enter the file’s content as the answer, one can use a file viewing tool such as cat or less to display the content of the file flag.txt. For example, the command cat /home/sam/flag.txt will display the content of the file flag.txt located in /home/sam/ directory5.

Cairo, an incident responder. was handling an incident observed in an organizational network. After performing all IH&R steps, Cairo initiated post-incident activities. He determined all types of losses caused by the incident by identifying And evaluating all affected devices, networks, applications, and software. Identify the post-incident activity performed by Cairo in this scenario.
Correct Answer:
A
Incident impact assessment is the post-incident activity performed by Cairo in this scenario. Incident impact assessment is a post-incident activity that involves determining all types of losses caused by the incident by identifying and evaluating all affected devices, networks, applications, and software. Incident impact assessment can include measuring financial losses, reputational damages, operational disruptions, legal liabilities, or regulatory penalties1. References: Incident Impact Assessment
Jase. a security team member at an organization, was tasked with ensuring uninterrupted business operations under hazardous conditions. Thus, Jase implemented a deterrent control strategy to minimize the occurrence of threats, protect critical business areas, and mitigate the impact of threats. Which of the following business continuity and disaster recovery activities did Jase perform in this scenario?
Correct Answer:
A
Prevention is the business continuity and disaster recovery activity performed by Jase in this scenario. Prevention is an activity that involves implementing a deterrent control strategy to minimize the occurrence of threats, protect critical business areas, and mitigate the impact of threats. Prevention can include measures such as backup systems, firewalls, antivirus software, or physical security1. References: Prevention Activity in BCDR
A software team at an MNC was involved in a project aimed at developing software that could detect the oxygen levels of a person without physical contact, a helpful solution for pandemic situations. For this purpose, the team used a wireless technology that could digitally transfer data between two devices within a short range of up to 5 m and only worked in the absence of physical blockage or obstacle between the two devices, identify the technology employed by the software team in the above scenario.
Correct Answer:
A
Infrared is a wireless technology that can digitally transfer data between two devices within a short range of up to 5 m and only works in the absence of physical blockage or obstacle between the two devices. Infrared is commonly used for remote controls, wireless keyboards, and medical devices.

Omar, an encryption specialist in an organization, was tasked with protecting low- complexity applications such as RFID tags, sensor-based applications, and other IbT- based applications. For this purpose, he employed an algorithm for all lower-powered devices that used less power and resources without compromising device security.
identify the algorithm employed by Omar in this scenario.
Correct Answer:
C
Lightweight cryptography is an algorithm that is designed for low-complexity applications such as RFID tags, sensor-based applications, and other IoT-based applications. Lightweight cryptography uses less power and resources without compromising device security. Lightweight cryptography can be implemented using symmetric-key algorithms, asymmetric-key algorithms, or hash functions1. References: Lightweight Cryptography
