All questions of Cyber Ethics for Class 10 Exam

Explanation:

Availability is the principle that ensures that a computer system or network is accessible and usable by authorized users when they need it. It refers to the accessibility of data, applications, and resources to authorized users, as well as the ability of the system to perform its intended functions.

Access control and confidentiality are related to security, but they do not necessarily ensure availability. Access control refers to the ability to restrict or grant access to specific resources or data based on user credentials or other criteria. Confidentiality refers to the protection of sensitive information from unauthorized disclosure or access.

If a computer system is no longer accessible, it means that the principle of availability has been violated. This can happen due to various reasons such as hardware or software failures, network outages, cyber-attacks, or other security incidents.

In conclusion, the correct answer is option C, availability, as it refers to the violation of the principle if a computer is no more accessible.

Computer Threats

Computer threats are malicious programs or activities that can harm computer systems, steal data or compromise the security of the system. There are different types of computer threats, including viruses, malware, spyware, ransomware, and more.

Dos Attack

A Denial of Service (DoS) attack is a type of cyber attack where the attacker floods the targeted computer or network with a huge amount of traffic, rendering it unavailable or slow. The attacker achieves this by sending multiple requests from different machines or networks, overloading the targeted system's resources. As a result, legitimate users are denied access to the service or website.

Phishing

Phishing is a type of social engineering attack where the attacker sends fraudulent emails or messages, pretending to be a trustworthy entity, to trick the recipient into revealing sensitive information such as usernames, passwords, and credit card details. The attacker can then use this information for malicious purposes, such as stealing money or identity theft.

Soliciting

Soliciting is a type of computer threat where the attacker tries to trick the user into downloading a malicious program or clicking on a malicious link by promising them something in return. For example, the attacker may offer free software or coupons in exchange for the user's personal information or clicking on a link.

Conclusion

Out of the given options, only DoS attack can be considered a class of computer threats. The other options, phishing and soliciting, are types of cyber attacks that fall under the broader category of social engineering attacks.

Introduction:
Confidentiality, Integrity, Availability, and Authenticity are considered as the fundamentals of security. These factors play a crucial role in understanding the concept of security and its components.

Explanation:
1. Confidentiality:
- Confidentiality refers to protecting sensitive information from unauthorized access or disclosure.
- It ensures that only authorized individuals or systems can access or view the information.
- Confidentiality is important to maintain privacy and prevent data breaches.

2. Integrity:
- Integrity ensures that data remains accurate, consistent, and trustworthy throughout its lifecycle.
- It involves protecting data from unauthorized modification, deletion, or corruption.
- Maintaining data integrity is crucial to ensure the reliability and validity of information.

3. Availability:
- Availability refers to ensuring that data, systems, and services are accessible and usable when needed.
- It involves preventing disruptions, downtime, or unauthorized denial of service.
- Availability is essential for continuous operations and to meet users' needs.

4. Authenticity:
- Authenticity ensures that data, information, or resources are genuine and can be trusted.
- It involves verifying the identity of users, systems, or messages to prevent impersonation or tampering.
- Authenticity helps establish trust and confidence in the integrity of the data.

Why are these factors considered as fundamentals?
- These factors are considered as fundamentals because they form the core principles of security.
- They provide a comprehensive framework for understanding and evaluating the security of systems and information.
- Confidentiality, integrity, availability, and authenticity are interconnected and mutually dependent on each other.
- They help in establishing a strong security foundation by addressing different aspects of security.
- By considering these factors, organizations can develop robust security measures and strategies to protect their assets and mitigate risks.

Conclusion:
Confidentiality, integrity, availability, and authenticity are fundamental factors in understanding security and its components. They provide the necessary framework to protect sensitive information, ensure data accuracy, enable continuous operations, and establish trust. By considering these factors, individuals and organizations can enhance their security posture and effectively mitigate security risks.

Confidentiality, Integrity, Availability are the three main principles. In Short, these three principles are also known as the CIA triad and plays a vital role as the cornerstone of the security structure of any organization.
