Which of the following is not an external threat to a computer or a computer network

Detailed Solution for Network Security MCQ Test - 1 - Question 1

External Threats to a Computer or Computer Network


External threats to a computer or computer network refer to potential risks and vulnerabilities that may compromise the security and functionality of the system. These threats are typically caused by malicious individuals or software. The options provided are:


A: Ignorance
- Ignorance is not an external threat to a computer or computer network. It refers to a lack of knowledge or awareness about computer security practices, but it is not a direct threat itself.
B: Trojan horses
- Trojan horses are a type of malware that disguises itself as legitimate software to gain unauthorized access or control over a computer or network. They can cause significant damage by stealing sensitive information, modifying data, or allowing remote control by hackers.
C: Adware
- Adware is a type of software that displays unwanted advertisements on a user's computer. While it can be annoying and intrusive, it is not typically considered a severe external threat to the overall security of a computer or network.
D: Crackers
- Crackers, also known as malicious hackers, are individuals who exploit vulnerabilities in computer systems or networks for personal gain or malicious intent. They can engage in activities such as unauthorized access, data theft, or disruption of services.

Therefore, the correct answer is:


Answer: A: Ignorance

It is important for computer users to be aware of potential threats and to take appropriate security measures to protect their systems and data.

With genetic and genomic research which of the following issues is of specific concern

Detailed Solution for Network Security MCQ Test - 1 - Question 3
Genetic and Genomic Research: Specific Concerns

When it comes to genetic and genomic research, there are several specific concerns that researchers and society need to address. One of the key concerns is anonymity, which refers to the protection of individuals' privacy and the confidentiality of their genetic information. This is particularly important considering the sensitive nature of genetic data and its potential implications.


Some specific concerns related to genetic and genomic research include:


1. Anonymity: Protecting the privacy and confidentiality of individuals' genetic information is crucial to prevent misuse or discrimination based on genetic data.
2. Intellectual Property: As genetic research progresses, there is a need to address issues related to patents and ownership of genetic sequences and technologies. This ensures fair access to research findings and prevents monopolization of genetic information.
3. Software Piracy: While not directly related to genetic research, the use of software in genomic analysis and interpretation raises concerns about intellectual property and unauthorized use or distribution of proprietary software.
4. Concerns about Biochip Implants: With advancements in technology, biochip implants have gained attention in the field of genetic research. Ethical concerns arise regarding the potential invasion of privacy and the risk of misuse of implanted devices.

In conclusion, while genetic and genomic research holds great potential for advancements in healthcare and understanding human biology, it is important to address specific concerns such as anonymity, intellectual property, software piracy, and concerns about biochip implants. These concerns help ensure the responsible and ethical conduct of research in this field.

Detailed Solution for Network Security MCQ Test - 1 - Question 4
Class of Computer Threats

There are various classes of computer threats that can compromise the security and integrity of computer systems. One such class of computer threat is:


DoS attacks:

  • Denial of Service (DoS) attacks are malicious attempts to disrupt the normal functioning of a computer network or website.

  • These attacks overwhelm the targeted system with a flood of illegitimate requests or excessive traffic, causing the system to become unresponsive or crash.

  • DoS attacks can be executed using various techniques, such as flooding the network with excessive data packets or exploiting vulnerabilities in the network infrastructure.

  • The main objective of a DoS attack is to disrupt the availability of a targeted system or service, rendering it inaccessible to legitimate users.

  • DoS attacks can have severe consequences, especially for businesses and organizations that heavily rely on their online presence for operations.


While phishing, soliciting, and stalking can also pose security threats in different contexts, they are not classified as specific computer threats. Therefore, the correct answer to the question is B: DoS attacks.

It is a program or hardware device that filters the information coming through an internet connection to a network or computer system.

Detailed Solution for Network Security MCQ Test - 1 - Question 6
Explanation:
A firewall is a program or hardware device that filters the information coming through an internet connection to a network or computer system. It acts as a barrier between the internal network and the external network (such as the internet) to protect the network from unauthorized access and potential threats. Here is a detailed explanation of how a firewall works:
1. Filtering:
- A firewall filters incoming and outgoing network traffic based on predetermined rules and policies.
- It examines the data packets and determines whether to allow or block them based on the defined criteria.
2. Network Security:
- Firewalls are an essential component of network security infrastructure.
- They help prevent unauthorized access to a network and protect against various threats such as hackers, malware, and viruses.
3. Types of Firewalls:
- There are different types of firewalls, including network firewalls, host-based firewalls, and application firewalls.
- Network firewalls are placed at the boundary between the internal network and the external network.
- Host-based firewalls are installed on individual devices to control their network connections.
- Application firewalls focus on specific applications and their communication.
4. Packet Inspection:
- Firewalls use packet inspection techniques to analyze the data packets traveling through the network.
- They examine the packet headers, source and destination IP addresses, ports, and other relevant information to determine whether the packet should be allowed or blocked.
5. Access Control:
- Firewalls enforce access control policies by allowing or denying traffic based on a set of rules.
- These rules can be based on IP addresses, port numbers, protocols, or application-specific criteria.
6. Logging and Monitoring:
- Firewalls provide logging and monitoring capabilities to track and analyze network traffic.
- They generate logs that contain information about blocked and allowed connections, which can be used for troubleshooting and security analysis.
In conclusion, a firewall is a crucial component of network security that filters and controls the flow of information between a network or computer system and the internet. It helps protect against unauthorized access, malicious activities, and potential threats.
