Homework Help: Questions and Answers: Someone who intends to gain unauthorized access to a computer system is called a:

A. Keylogger
B. Virus
C. Trojan horse
D. Hacker
E. Malware specialist

Answer:

First, let’s understand the question: It’s about to determine the unauthorized access to a computer system.

Given Options: Step by Step Answering

a) Keylogger

• A keylogger is a type of software or hardware device that records the keystrokes of a user, typically to gain access to sensitive information like passwords. However, it is not the person or individual who intends to gain unauthorized access, but rather a tool used for such purposes.

b) Virus

• A virus is a malicious program that can replicate itself and spread from one computer to another. It can cause harm to a system, but it is not the person who attempts to gain unauthorized access. A virus is a type of malware, not the actor.

c) Trojan horse

• A Trojan horse is a type of malware that appears to be legitimate software but performs malicious actions once installed. Like a virus, it is a tool, not the person or actor attempting unauthorized access.

d) Hacker

• A hacker is an individual who attempts to gain unauthorized access to computer systems. This could be for malicious purposes (black hat hacking), ethical reasons (white hat hacking), or something in between (gray hat hacking).

e) Malware specialist

• A malware specialist is a professional who deals with malware—either creating, studying, or removing it. This person may work in cybersecurity but isn’t specifically defined as someone who attempts unauthorized access.

Final Answer:

Based on the above analysis, the correct answer is:

d) Hacker

A hacker is specifically a person who attempts to gain access to computer systems, and in this context, we’re referring to those who do so without authorization (black hat hackers). The other options are either tools (keylogger, virus, Trojan horse) or not precisely focused on unauthorized access (malware specialist).
