Question

Which of the following function is not a way to protect data?

• A. Password
• B. Antivirus and firewall
• C. Secure sites
• D. Trojan horse

Hint:

Always differentiate between security tools (passwords, firewalls) and security threats (viruses, trojans, malware). The question asks for something that is NOT a way to protect data, which points directly to a threat.

Answer 1

The Correct Option is D

Step 1: Understand data protection methods.
Data protection refers to the processes and mechanisms used to secure digital information from corruption, compromise, or loss. Common methods include access controls, security software, and safe browsing practices.
Step 2: Distinguish between protective measures and threats.
It is crucial to differentiate between tools that enhance security and those that are actually malicious programs designed to bypass security.
Step 3: Analysis of each option.

• (A) Password: This is a protective measure.} Passwords restrict access to data, ensuring only authorized users can view or modify it.
• (B) Antivirus and firewall: This is a protective measure.} Antivirus software detects and removes malicious programs, while a firewall monitors and controls incoming and outgoing network traffic based on security rules.
• (C) Secure sites: This is a protective measure.} Secure websites (using HTTPS) encrypt data transmitted between the user and the site, protecting it from interception.
• (D) Trojan horse: This is NOT a protective measure.} A Trojan horse is a type of malicious software (malware) that disguises itself as legitimate software to trick users into installing it. Once installed, it can steal, corrupt, or delete data. It is a threat to data, not a way to protect it.

Step 4: Conclusion.
Passwords, antivirus/firewall software, and secure sites are all methods used to safeguard data. In contrast, a Trojan horse is a harmful program designed to compromise data security. Final Answer:} (D) Trojan horse
