Admissible is the rule of evidence discussed in the above scenario. A rule of evidence is a criterion or principle that determines whether a piece of evidence can be used in a legal proceeding or investigation. Admissible is a rule of evidence that states that the evidence must be relevant, reliable, authentic, and understandable to be accepted by a court or a jury . Admissible also means that the evidence must be obtained legally and ethically, without violating any laws or rights. In the scenario, Kason has documented all the supporting documents, including source of the evidence and its relevance to the case, before presenting it in front of the jury, which means that he has followed the admissible rule of evidence. Authentic is a rule of evidence that states that the evidence must be original or verifiable as genuine and not altered or tampered with. Understandable is a rule of evidence that states that the evidence must be clear and comprehensible to the court or jury and not ambiguous or confusing. Reliable is a rule of evidence that states that the evidence must be consistent and trustworthy and not based on hearsay or speculation.

Investigation objectives is the section of the forensic investigation report where Arabella recorded the "nature of the claim and information provided to the officers" in the above scenario. A forensic investigation report is a document that summarizes the findings and conclusions of a forensic investigation. A forensic investigation report typically follows a standard template that contains different sections covering all the details of the crime and the investigation process. Investigation objectives is the section of the forensic investigation report that describes the purpose and scope of the investigation, the nature of the claim and information provided to the officers, and the questions or issues to be addressed by the investigation. Investigation process is the section of the forensic investigation report that describes the steps and methods followed by the investigators, such as evidence collection, preservation, analysis, etc. Evidence information is the section of the forensic investigation report that lists and describes the evidence obtained from various sources, such as devices, media, witnesses, etc. Evaluation and analysis process is the section of the forensic investigation report that explains how the evidence was evaluated and analyzed using various tools and techniques, such as software, hardware, etc.

Turn the device ON if it is OFF, do not leave the device as it is if it is ON, and make sure that the device is charged are some of the points that Shawn must follow while preserving the digital evidence in the above scenario. Digital evidence is any information or data stored or transmitted in digital form that can be used in a legal proceeding or investigation. Digital evidence can be found on various devices, such as computers, mobile phones, tablets, etc. Preserving digital evidence is a crucial step in forensic investigation that involves protecting and maintaining the integrity and authenticity of digital evidence from any alteration or damage. Some of the points that Shawn must follow while preserving digital evidence are:

Turn the device ON if it is OFF: If the device is OFF, Shawn must turn it ON to prevent any data loss or encryption that may occur when the device is powered off. Shawn must also document any password or PIN required to unlock or access the device.

Do not leave the device as it is if it is ON: If the device is ON, Shawn must not leave it as it is or use it for any purpose other than preserving digital evidence. Shawn must also disable any network connections or communication features on the device, such as Wi-Fi, Bluetooth, cellular data, etc., to prevent any remote access or deletion of data by unauthorized parties.

Make sure that the device is charged: Shawn must ensure that the device has enough battery power to prevent any data loss or corruption that may occur due to sudden shutdown or low battery. Shawn must also use a write blocker or a Faraday bag to isolate the device from any external interference or signals.

Never record the screen display of the device is not a point that Shawn must follow while preserving digital evidence. On contrary, Shawn should record or photograph the screen display of the device to capture any relevant information or messages that may appear on the screen. Recording or photographing the screen display of the device can also help document any changes or actions performed on the device during preservation.

Bit-stream imaging is the method utilized by Ruben in the above scenario. Bit-stream imaging is a method that involves creating a cloned copy of the entire media and prevents the contamination of the original media. Bit-stream imaging copies all the data on the media, including deleted files and folders, hidden partitions, slack space, etc., at a bit level. Bit-stream imaging preserves the integrity and authenticity of the digital evidence and allows further analysis without affecting the original media. Sparse acquisition is a method that involves creating a partial copy of the media by skipping empty sectors or blocks. Drive decryption is a method that involves decrypting an encrypted drive or partition using a password or a key. Logical acquisition is a method that involves creating a copy of the logical files and folders on the media using file system commands.

Recovery is the business continuity and disaster recovery activity that Kasen performed in the above scenario. Business continuity and disaster recovery (BCDR) is a process that involves planning, preparing, and implementing various activities to ensure the continuity of critical business functions and the recovery of essential resources in the event of a disaster or disruption. BCDR activities can be categorized into four phases: prevention, response, resumption, and recovery . Prevention is the BCDR phase that involves identifying and mitigating potential risks and threats that can cause a disaster or disruption. Response is the BCDR phase that involves activating the BCDR plan and executing the immediate actions to protect people, assets, and operations during a disaster or disruption. Resumption is the BCDR phase that involves restoring the minimum level of services and functions required to resume normal business operations after a disaster or disruption. Recovery is the BCDR phase that involves restoring both the disaster site and the damaged materials to the predisaster levels during an incident.

Risk treatment is the risk management phase that Cassius was instructed to perform in the above scenario. Risk management is a process that involves identifying, analyzing, evaluating, treating, monitoring, and reviewing risks that can affect an organization's objectives, assets, or operations.

Risk management phases can be summarized as follows: risk identification, risk analysis, risk prioritization, risk treatment, and risk monitoring . Risk identification is the risk management phase that involves identifying and documenting potential sources, causes, events, and impacts of risks.

Risk analysis is the risk management phase that involves assessing and quantifying the likelihood and consequences of risks. Risk prioritization is the risk management phase that involves ranking risks based on their severity level and determining which risks need immediate attention or action. Risk treatment is the risk management phase that involves selecting and implementing appropriate controls or strategies to address risks based on their severity level . Risk treatment can include avoiding, transferring, reducing, or accepting risks. Risk monitoring is the risk management phase that involves tracking and reviewing the performance and effectiveness of risk controls or strategies over time.

hat@red is the FTP credential that was stolen using Cain and Abel in the above scenario. FTP (File Transfer Protocol) is a protocol that allows transferring files between a client and a server over a network. FTP requires a username and a password to authenticate the client and grant access to the server . Cain and Abel is a tool that can perform various network attacks, such as ARP poisoning, password cracking, sniffing, etc. Cain and Abel can poison the machine and fetch the FTP credentials used by the admin by intercepting and analyzing the network traffic .

20.20.10.19 is the source IP address of the SYN flooding attack in the above scenario. SYN flooding is a type of denial-of-service (DoS) attack that exploits the TCP (Transmission Control Protocol) threeway handshake process to disrupt the network and gain advantage over the network to bypass the firewall. SYN flooding sends a large number of SYN packets with spoofed source IP addresses to a target server, causing it to allocate resources and wait for the corresponding ACK packets that never arrive. This exhausts the server's resources and prevents it from accepting legitimate requests . To determine the source IP address of the SYN flooding attack, one has to follow these steps:

Navigate to the Documents folder of Attacker-1 machine.

Double-click on Synflood.pcapng file to open it with Wireshark.

Click on Statistics menu and select Conversations option.

Click on TCP tab and sort the list by Bytes column in descending order.

Observe the IP address that has sent the most bytes to 20.20.10.26 (target server).

The IP address that has sent the most bytes to 20.20.10.26 is 20.20.10.19 , which is the source IP address of the SYN flooding attack.
