Free D340 Cyber Defense and Countermeasures Questions
What is a primary reason that attackers target intellectual property (IP) in cybercrime?
-
To gain competitive advantage by stealing proprietary information
-
To disrupt services and cause financial loss
-
To recruit individuals for terrorist activities
-
To spread malware across networks
Explanation
Explanation:
Attackers target intellectual property (IP) to steal proprietary information, such as designs, patents, formulas, or business strategies, which can provide them or their organization with a competitive advantage. This type of cybercrime focuses on obtaining valuable knowledge rather than directly disrupting services, recruiting individuals, or spreading malware. IP theft can have long-term economic and strategic consequences for the victim organization.
Correct Answer:
To gain competitive advantage by stealing proprietary information
What is an example of a payload?
-
Web application exploits
-
Buffer overflows
-
Code injection
-
Malicious DLLs
Explanation
Explanation:
A payload in cybersecurity refers to the part of malware or an exploit that performs the intended malicious action after the vulnerability has been successfully exploited. Malicious DLLs are an example of a payload because they execute harmful functions on the victim’s system, such as stealing data or providing unauthorized access. The other options—web application exploits, buffer overflows, and code injection—are methods used to deliver or trigger the payload, not the payload itself.
Correct Answer:
Malicious DLLs
In a Distributed Denial of Service (DDoS) assault, what is the main purpose of a botnet?
-
To encrypt data on the victim's server
-
To send spam emails to users
-
To overwhelm a target server with traffic
-
To steal sensitive information from users
Explanation
Explanation:
A botnet is a network of compromised computers controlled by an attacker to perform coordinated actions. In a DDoS attack, the botnet’s primary function is to flood the target server with massive amounts of traffic, overwhelming its resources and rendering it inaccessible to legitimate users. While botnets can be used for sending spam or stealing information, their role in a DDoS attack specifically focuses on disrupting availability by saturating the target with traffic.
Correct Answer:
To overwhelm a target server with traffic
Traditional hackers are motivated by ________.
-
thrill
-
validation of power
-
doing damage as a by-product
-
All of the above
Explanation
Explanation:
Traditional hackers are typically motivated by a combination of thrill, the validation of their skills and power, and sometimes causing damage as a secondary effect. Their actions are often driven by curiosity, challenge, and the desire to demonstrate technical ability rather than financial gain. Therefore, all the listed motivations collectively describe the common driving factors for traditional hackers.
Correct Answer:
All of the above
Which of the following actions would be considered a violation of a company's IT use policies?
-
Using company resources for personal projects during work hours
-
Accessing company emails for work-related communication
-
Participating in a company-sponsored training program
-
Using company software for approved business tasks
Explanation
Explanation:
Using company resources for personal projects during work hours is considered a violation of IT use policies because it diverts organizational resources from their intended professional use. Companies establish IT policies to ensure that computers, software, and network access are used primarily for business purposes, to maintain productivity, security, and compliance. Personal use of these resources, unless explicitly permitted, breaches these guidelines, whereas the other actions listed are aligned with proper, policy-compliant usage.
Correct Answer:
Using company resources for personal projects during work hours
Instructions or code that executes on an end user's machine from a web browser is known as _________ code.
-
Active X
-
JavaScript
-
Malware
-
Windows Scripting
-
Mobile
Explanation
Explanation:
JavaScript is a programming language commonly used to execute instructions directly in a web browser on the client side. It can provide dynamic content, interactivity, and automation in web pages. While it can sometimes be exploited for malicious purposes, its defining feature is that it runs in the end user’s browser. Other options like ActiveX, Windows Scripting, or mobile code refer to different execution environments or contexts.
Correct Answer:
JavaScript
What is the purpose of a rootkit?
-
to gain privileged access to a device while concealing itself
-
to deliver advertisements without user consent
-
to replicate itself independently of any other programs
-
to masquerade as a legitimate program
Explanation
Explanation:
A rootkit is a type of malicious software designed to obtain and maintain privileged access to a computer system while hiding its presence. It allows attackers to manipulate or control the system without detection, bypassing security measures and concealing malicious activity. Unlike adware, worms, or Trojans that replicate or disguise themselves for other purposes, the core function of a rootkit is stealthy, unauthorized control of the system.
Correct Answer:
to gain privileged access to a device while concealing itself
What is the primary function of a computer virus once it infects a legitimate program on a victim's machine?
-
To delete files from the computer
-
To replicate itself and attach to other programs
-
To encrypt sensitive data
-
To disable the computer's firewall
Explanation
Explanation:
A computer virus primarily functions to replicate itself by attaching to legitimate programs, enabling it to spread to other programs and systems. While some viruses may have additional payloads such as deleting files or encrypting data, the defining characteristic of a virus is its self-replication and ability to propagate through infected programs. This distinguishes it from other types of malware with different primary purposes.
Correct Answer:
To replicate itself and attach to other programs
Why is stealing intellectual property important to cyber espionage criminals?
-
It can give them access to who a company's top customers currently are.
-
Most cybercriminals aren't interested in intellectual property, only money.
-
It can give them access to sensitive organizational operations data.
-
It can give them access to research and development they don't have.
Explanation
Explanation:
Stealing intellectual property (IP) is a primary goal of cyber espionage because it provides criminals with access to proprietary research, development, and innovations that the organization has created. This information can be exploited for competitive advantage, financial gain, or to undermine the organization’s market position. Unlike customer data, which is more relevant for direct financial crimes, IP theft targets the strategic and technological assets of a company, giving attackers knowledge they would not otherwise have.
Correct Answer:
It can give them access to research and development they don't have.
What is it called when an unauthorized person views, alters, or steals secured data?
-
Data breach
-
Pharming
-
Data jacking
-
Copyright infringement
-
Phishing
Explanation
Explanation:
A data breach occurs when an unauthorized individual gains access to, views, alters, or steals secured or sensitive information. This can involve personal data, financial information, or proprietary business data. Unlike pharming, data jacking, copyright infringement, or phishing, a data breach specifically refers to the compromise of data confidentiality, integrity, or availability.
Correct Answer:
Data breach
