Jacob, a network defender in an organization, was instructed to improve the physical security measures to prevent unauthorized intrusion attempts. In this process, Jacob implemented certain physical security controls by using warning messages and signs that notify legal consequences to discourage hackers from making intrusion attempts.
Which of the following type of physical security controls has Jacob implemented in the above scenario?
A disk drive has 16.384 cylinders, 80 heads, and 63 sectors per track, and each sector can store 512 bytes of data. What is the total size of the disk?
Answer : B
Sectors per Cylinder: Multiply heads * sectors per track: 80 * 63 = 5040 sectors/cylinder
Bytes per Cylinder: Multiply sectors per cylinder * bytes per sector: 5040 * 512 = 2,580,480 bytes/cylinder
Total Bytes: Multiply bytes per cylinder * total cylinders: 2,580,480 * 16,384 = 42,278,584,320 bytes
Explanation
To find the total disk size, we need to calculate the storage capacity per cylinder and then multiply that by the total number of cylinders.
Michael, a forensic expert, was assigned to investigate an incident that involved unauthorized intrusion attempts. In this process, Michael identified all the open ports on a system and disabled them because these open ports can allow attackers to install malicious services and compromise the security of the system or network.
Which of the following commands assisted Michael in identifying open ports in the above scenario?
Answer : B
Michael used thenetstatcommand with the-ioption to identify open ports on the system. The-iflag displays network interfaces and their statistics, including information about open ports. By analyzing this output, Michael could determine which ports were active and potentially vulnerable to unauthorized access.

Identify the backup mechanism that is performed within the organization using external devices such as hard disks and requires human interaction to perform the backup operations, thus, making it suspect able to theft or natural disasters.
Answer : D
The backup mechanism described in the scenario, which involves using external devices (such as hard disks) and requires human interaction for backup operations, is known asonsite data backup. In this approach, backups are stored within the organization's premises, making them susceptible to theft, damage, or natural disasters. It is essential to consider additional offsite or cloud-based backup solutions to enhance data resilience and security.
Williams, a forensic specialist, was tasked with performing a static malware analysis on a suspect system in an organization. For this purpose, Williams used an automated tool to perform a string search and saved all the identified strings in a text file. After analyzing the strings, he determined all the harmful actions that were performed by malware.
Identify the tool employed by Williams in the above scenario.
Answer : A
The scenario's focus on extracting strings from a suspect system for malware analysis aligns with the functionality of tools like ResourcesExtract:
ResourcesExtract's Purpose:It's designed to extract specific resources, including strings, from executables and other file types. This is crucial for static malware analysis.
String Search and Analysis:Finding and analyzing embedded strings can reveal malicious code behavior, function calls, and other clues about the malware's intent.
An investigator wants to extract information about the status of the network interface cards (NICs) in an organization's Windows-based systems. Identify the command-line utility that can help the investigator detect the network status.
Answer : A
Theipconfigcommand displays the configuration of all network interfaces on a Windows system. It provides information about IP addresses, subnet masks, default gateways, DNS servers, and other network-related settings. By runningipconfig, an investigator can quickly view the status of NICs and their associated network parameters.

Answer : C
To provide Internet access to every laptop and bring all the devices to a single network, Bob should usemultiple wireless access points. These access points can be connected to the same wired network and provide wireless connectivity to the laptops in different rooms. By strategically placing these access points, Bob can ensure coverage throughout the company premises.
