True / False Exercise-societal Impact

Explanation
Trojan horses are not similar to viruses in the sense that they do not replicate copies of themselves. While viruses are self-replicating programs that can spread and infect other files, Trojan horses are deceptive programs that disguise themselves as legitimate software but actually contain malicious code. They do not have the ability to reproduce or spread on their own. Therefore, the statement is false.

Explanation
A license grants permission to a user to use copyrighted material. This means that the user has legal authorization to access, utilize, and sometimes even modify or distribute the copyrighted work. Without a license, the user would be infringing on the copyright holder's exclusive rights and could face legal consequences. Therefore, the statement "A license allows a user to use copyright material" is true.

Explanation
Hacking a computer refers to unauthorized access or intrusion into someone's computer system or network. It involves bypassing security measures and can lead to theft of sensitive information, financial loss, or disruption of services. Such activities are considered illegal as they violate privacy laws and can cause harm. Therefore, hacking a computer is indeed always illegal and punishable by law.

Explanation
Malware is a general term used to describe malicious software that can harm computer systems. It is not limited to a specific operating system and can affect both Windows and Linux systems. This is because malware can be designed to exploit vulnerabilities in various software and hardware components that are common to both operating systems. Therefore, it is true that malware can affect both Windows and Linux systems.

Explanation
Identity theft refers to the act of someone using another person's personal information without their consent to pose as the victim for their own gain. This can involve stealing sensitive data such as social security numbers, credit card information, or passwords, and using it to commit fraudulent activities like making unauthorized purchases or accessing financial accounts. Therefore, the statement "Identity theft is the term used when a cyber-thief uses anybody's personal information to impersonate the victim for their benefit" is true.

Explanation
An ethical hacker needs to possess a range of skills in order to effectively understand and address security vulnerabilities. Understanding the problem at hand is crucial for identifying potential weaknesses and devising appropriate countermeasures. Networking knowledge is essential for comprehending the intricacies of network infrastructure and identifying potential entry points for malicious attacks. Additionally, having knowledge of how technology works enables ethical hackers to exploit vulnerabilities and develop effective security measures. Therefore, it is true that an ethical hacker must possess these skills.

Explanation
System hacking involves password hacking as one of the major hacking methodologies. This is true because password hacking is a common technique used in system hacking to gain unauthorized access to a computer system or network. By cracking passwords, hackers can bypass security measures and gain control over the system, allowing them to steal sensitive information, install malware, or carry out other malicious activities. Therefore, password hacking plays a significant role in system hacking.

Explanation
Passwords need to be kept encrypted to protect from offline attacks because if passwords are stored in plain text, anyone who gains access to the database or file containing the passwords can easily read and use them. Encrypting passwords ensures that even if the database or file is compromised, the passwords are still protected and cannot be easily deciphered. Encryption adds an extra layer of security and helps in safeguarding sensitive information from unauthorized access.

Explanation
Saving passwords in the browser is not a good habit because it poses security risks. Storing passwords in the browser makes them vulnerable to hacking and unauthorized access. If someone gains access to the browser or the device, they can easily retrieve all saved passwords. It is recommended to use a password manager or memorize passwords instead of relying on the browser's built-in password saving feature.

Explanation
The explanation for the given correct answer is that data protection primarily focuses on safeguarding the privacy and security of data that is stored in digital format. This involves implementing measures to prevent unauthorized access, use, or disclosure of sensitive information. Data protection also includes strategies for data backup, encryption, and compliance with relevant regulations and policies to ensure the confidentiality and integrity of digital data.
