Question 1
Bonney's system has been compromised by a gruesome malware.
What is the primary step that is advisable to Bonney in order to contain the malware incident from spreading?
- A. Complaint to police in a formal way regarding the incident
- B. Turn off the infected machine
- C. Leave it to the network administrators to handle
- D. Call the legal department in the organization and inform about the incident
Correct Answer:
B
Explanation:
The suggested answer, B (Turn off the infected machine), is the recommended first step.
The primary reason for this recommendation is to immediately isolate the compromised system from the network, thereby preventing the malware from spreading to other devices or accessing sensitive data. This aligns with standard incident response procedures.
Option A (Complaint to police) and D (Call the legal department) are not the primary *containment* steps. While these actions may be necessary later, they don't address the immediate threat of malware propagation. Option C (Leave it to network administrators) is insufficient as an immediate reaction; while administrators should be involved, immediate action is required to contain the spread, and simply "leaving it" could allow further damage.

Question 2
According to the forensics investigation process, what is the next step carried out right after collecting the evidence?
- A. Create a Chain of Custody Document
- B. Send it to the nearby police station
- C. Set a Forensic lab
- D. Call Organizational Disciplinary Team
Correct Answer:
A
Explanation:
The AI concurs with the suggested answer. The next step immediately following evidence collection in a forensics investigation process is to create a Chain of Custody Document (Option A).
Reasoning:
A Chain of Custody document is a crucial record that tracks the evidence from its collection through analysis and storage, ensuring its integrity and admissibility in court. This document meticulously details every person who handled the evidence, the dates and times of transfer, and the purpose of each transfer. Maintaining a well-documented Chain of Custody is essential to prevent any accusations of tampering or mishandling of the evidence, thereby preserving its legal value.
Why other options are incorrect:
- Option B, "Send it to the nearby police station," might be a step later in the process, but creating the Chain of Custody *immediately* after collection is paramount. The evidence needs to be documented before it is transferred.
- Option C, "Set a Forensic lab," is not the immediate next step. A forensic lab might already exist, or setting one up would be a much larger undertaking that comes into play later in the investigation.
- Option D, "Call Organizational Disciplinary Team," is a separate action that depends on the organization's procedures and the nature of the incident, and doesn't directly relate to the immediate handling of the evidence itself.

Question 3
Which one of the following is the correct flow for Setting Up a Computer Forensics Lab?
- A. Planning and budgeting –> Physical location and structural design considerations –> Work area considerations –> Human resource considerations –> Physical security recommendations –> Forensics lab licensing
- B. Planning and budgeting –> Physical location and structural design considerations–> Forensics lab licensing –> Human resource considerations –> Work area considerations –> Physical security recommendations
- C. Planning and budgeting –> Forensics lab licensing –> Physical location and structural design considerations –> Work area considerations –> Physical security recommendations –> Human resource considerations
- D. Planning and budgeting –> Physical location and structural design considerations –> Forensics lab licensing –>Work area considerations –> Human resource considerations –> Physical security recommendations
Correct Answer:
A
Explanation:
The AI agrees with the suggested answer of A.
The most logical and efficient flow for setting up a computer forensics lab begins with meticulous planning and budgeting. Following this, the physical location and structural design need to be addressed to ensure the lab meets specific requirements (e.g., power, cooling, network connectivity). Subsequently, considerations for the work area (layout, equipment placement) are important for operational efficiency. Human resource considerations (staffing, training) follow, as the lab's effectiveness depends on skilled personnel. Next, physical security recommendations are implemented to protect evidence and equipment. Finally, forensics lab licensing ensures compliance with legal and industry standards.
The order presented in option A reflects a logical sequence, prioritizing essential steps before moving to subsequent ones.
Here's why the other options are less suitable:
- Options B, C, and D incorrectly place "Forensics lab licensing" earlier in the process. Obtaining licenses is typically one of the final steps after the physical infrastructure and operational aspects have been established.
The user discussion points to student manual page 687, which likely details the proper sequence for lab setup. However, without direct access to the student manual, a more general citation regarding the logical steps in establishing a forensics lab is provided below.
This recommendation is based on general best practices in lab setup and the logical flow of establishing a secure and functional computer forensics environment.

Question 4
Which of the following directory will contain logs related to printer access?
- A. /var/log/cups/Printer_log file
- B. /var/log/cups/access_log file
- C. /var/log/cups/accesslog file
- D. /var/log/cups/Printeraccess_log file
Correct Answer:
B
Explanation:
The AI agrees with the suggested answer.
The suggested answer is B: /var/log/cups/access_log file.
Reasoning: The /var/log/cups/access_log file is the standard location for logging printer access information in CUPS (Common Unix Printing System). This log file records details about print jobs, including who printed, when, and what was printed.
Reasons for not choosing other options:
- A: /var/log/cups/Printer_log file: While CUPS does use a printer-specific log file, its name is usually "error_log", not "Printer_log".
- C: /var/log/cups/accesslog file: This is very similar to the correct answer, but the correct name is "access_log" and not "accesslog".
- D: /var/log/cups/Printeraccess_log file: There's no standard CUPS log file named "Printeraccess_log".
-
Question 5
Which of the following command is used to enable logging in iptables?
- A. $ iptables -B INPUT -j LOG
- B. $ iptables -A OUTPUT -j LOG
- C. $ iptables -A INPUT -j LOG
- D. $ iptables -B OUTPUT -j LOG
Correct Answer:
C
Explanation:
The AI agrees with the suggested answer, C. $ iptables -A INPUT -j LOG.
Reasoning:
- The command
iptables -A INPUT -j LOG is used to append a rule to the INPUT chain in iptables, which will log incoming packets. The -A option appends the rule to the specified chain (INPUT in this case). The -j LOG option specifies that the target for matching packets is to log them.
- The INPUT chain is used for packets coming into the server. Logging these packets can be helpful for security monitoring and troubleshooting.
Reasons for not choosing other answers:
- Option A,
$ iptables -B INPUT -j LOG, is incorrect because -B is not a valid option in iptables. The -B option is not recognized by iptables, causing a syntax error.
- Option B,
$ iptables -A OUTPUT -j LOG, logs packets leaving the server (outgoing packets). While logging outgoing packets can be useful in some situations, the question does not specify whether to log outgoing or incoming packets, so logging INPUT packets as the suggested answer does is the more correct general answer. Also, the 312-39 course material explicitly describes using the INPUT chain.
- Option D,
$ iptables -B OUTPUT -j LOG, is incorrect as -B is not a valid option in iptables, and it refers to the OUTPUT chain.
Based on the information and the consensus, the best answer is C. $ iptables -A INPUT -j LOG.

Question 6
Ray is a SOC analyst in a company named Queens Tech. One Day, Queens Tech is affected by a DoS/DDoS attack. For the containment of this incident, Ray and his team are trying to provide additional bandwidth to the network devices and increasing the capacity of the servers.
What is Ray and his team doing?
- A. Blocking the Attacks
- B. Diverting the Traffic
- C. Degrading the services
- D. Absorbing the Attack
Correct Answer:
D
Explanation:
The AI agrees with the suggested answer.
Suggested Answer: D
Reasoning: The actions described – providing additional bandwidth to network devices and increasing server capacity – directly correspond to the strategy of absorbing a DDoS attack. This involves scaling up resources to handle the increased traffic volume, preventing service degradation. This is a common mitigation technique for DoS/DDoS attacks, aiming to maintain service availability despite the malicious traffic.
Why other options are incorrect:
- A. Blocking the Attacks: While blocking malicious traffic is part of DDoS mitigation, simply blocking doesn't address the overwhelming volume of traffic. The scenario describes increasing capacity, not just filtering traffic.
- B. Diverting the Traffic: Diverting traffic, often through techniques like traffic scrubbing, is another mitigation strategy, but it's not what's explicitly described in the question. The focus is on increasing internal capacity.
- C. Degrading the services: Degrading services would be the result of a DoS/DDoS attack if no mitigation strategies are in place. The described actions are aimed at preventing this degradation, not causing it.
Based on the courseware Module 6 pg 792 (as cited in the discussion summary), absorbing the attack is aligned with the provided actions for incident containment.

Question 7
Identify the attack when an attacker by several trial and error can read the contents of a password file present in the restricted etc folder just by manipulating the URL in the browser as shown: http://www.terabytes.com/process.php./../../../../etc/passwd
- A. Directory Traversal Attack
- B. SQL Injection Attack
- C. Denial-of-Service Attack
- D. Form Tampering Attack
Correct Answer:
A
Explanation:
The AI agrees with the suggested answer.
The suggested answer is A: Directory Traversal Attack.
Reasoning: The provided URL `http://www.terabytes.com/process.php./../../../../etc/passwd` demonstrates an attempt to access the `/etc/passwd` file by navigating up the directory structure using `../`. This is the core characteristic of a directory traversal attack.
Why other options are incorrect:
- B. SQL Injection Attack: This involves injecting malicious SQL code into queries, which isn't the case here.
- C. Denial-of-Service Attack: This aims to make a service unavailable, not to read files.
- D. Form Tampering Attack: This involves modifying form data submitted by a user, not directly accessing files.
The attacker is manipulating the URL to bypass security measures and access sensitive files, which is a classic example of directory traversal. Therefore, option A is the most appropriate answer.
-
Question 8
Which encoding replaces unusual ASCII characters with "%" followed by the character’s two-digit ASCII code expressed in hexadecimal?
- A. Unicode Encoding
- B. UTF Encoding
- C. Base64 Encoding
- D. URL Encoding
Correct Answer:
D
Explanation:
The AI agrees with the suggested answer.
The suggested answer is D (URL Encoding).
Reasoning: URL encoding is specifically designed to handle unusual ASCII characters by replacing them with a "%" followed by the character's two-digit ASCII code in hexadecimal format. This ensures that URLs can correctly transmit special characters that might otherwise be misinterpreted by web servers or browsers.
Reasons for not choosing other options:
- A. Unicode Encoding: Unicode is a character encoding standard that assigns a unique number to each character, but it doesn't inherently use the "%" followed by hexadecimal representation for unusual characters.
- B. UTF Encoding: UTF (Unicode Transformation Format) is a family of character encodings that represent Unicode code points as sequences of one or more bytes. While UTF encodings handle a wide range of characters, they don't use the specific "%" followed by hexadecimal representation for encoding unusual ASCII characters in the same way as URL encoding.
- C. Base64 Encoding: Base64 is a general-purpose encoding scheme that represents binary data in an ASCII string format by translating it into a base-64 representation. It's not specifically designed for encoding unusual characters in URLs using the "%" followed by hexadecimal format.
Citation: Official Courseware, Volume 2, pg. 834 (While the specific content of this courseware cannot be accessed directly, the discussion explicitly mentions its support for option D as the correct answer.)

Question 9
Which of the following formula represents the risk?
- A. Risk = Likelihood × Severity × Asset Value
- B. Risk = Likelihood × Consequence × Severity
- C. Risk = Likelihood × Impact × Severity
- D. Risk = Likelihood × Impact × Asset Value
Correct Answer:
D
Explanation:
The AI agrees with the suggested answer of D. Risk = Likelihood × Impact × Asset Value.
The main reason for this selection is that this formula correctly represents the relationship between the likelihood of an event, the impact it would have, and the value of the asset at risk.
This is a standard formula used in risk assessment and management to quantify risk.
The AI did not select other options, because:
- A. Risk = Likelihood × Severity × Asset Value: While severity is a component of risk, 'Impact' is a more comprehensive term that encompasses all potential consequences.
- B. Risk = Likelihood × Consequence × Severity: Consequence and Severity are similar, but the asset value needs to be considered.
- C. Risk = Likelihood × Impact × Severity: Again, the asset value needs to be considered. Without considering asset value, the formula remains incomplete.
Based on the discussion, several sources mention this formula. It's commonly used and considered a fundamental concept in risk management. The discussion pointed to study materials that specifically support option D as correct.

Question 10
The Syslog message severity levels are labelled from level 0 to level 7.
What does level 0 indicate?
- A. Alert
- B. Notification
- C. Emergency
- D. Debugging
Correct Answer:
C
Explanation:
The suggested answer is C. Emergency.
The AI agrees with the suggested answer.
The reason for this choice is that Syslog level 0 indicates an emergency condition, signifying that the system is unusable. Syslog severity levels range from 0 to 7, with 0 being the most severe.
Here's a breakdown of why the other options are incorrect:
- A. Alert: Alert represents a less severe condition than emergency.
- B. Notification: Notification is an informational message, indicating normal operational events.
- D. Debugging: Debugging messages are used for troubleshooting and are the least severe.
