Cyber-hacker Protection Test 1

Question 1

Which of the following best describes a hacker of computers?

Accepted Answer

An expert coder who sneakily breaks into computers without authorization.

Answer

In the context of cybersecurity, a hacker is typically defined as an individual who gains unauthorized access to computer systems or networks. This access is often achieved through exploiting vulnerabilities, bypassing security measures, and without the explicit permission of the system owner. Their motivations can range from malicious intent to ethical security testing.

Question 2

Which of the following is a phishing example?

Accepted Answer

An email instructing the recipient to input personal information on a phony website

Answer

Phishing is a social engineering attack where attackers attempt to trick individuals into revealing sensitive information, such as usernames, passwords, or credit card details. This is commonly done through deceptive emails or messages that appear to be from a legitimate entity, instructing the recipient to click a link to a fake website where they are prompted to enter their personal data.

Question 3

The idea of utilizing the same key for both encryption and decryption is known as .

Accepted Answer

Symmetric key system

Answer

A symmetric key system, also known as symmetric-key cryptography, uses a single, shared secret key for both encrypting and decrypting data. This means the same key used to scramble the information is also used to unscramble it. While efficient, secure communication requires both parties to securely exchange and manage this shared secret key.

Question 4

Virtual "listening in" on data exchanged over a WiFi network that is not secure (not encrypted).

Accepted Answer

Wi-Fi Eavesdropping

Answer

Wi-Fi Eavesdropping refers to the act of intercepting and monitoring data transmitted over an unsecured (unencrypted) Wi-Fi network. Attackers can 'listen in' on network traffic, capturing sensitive information like login credentials, personal messages, or financial data as it travels wirelessly. Using encrypted Wi-Fi protocols like WPA2/WPA3 helps prevent this.

Question 5

Of the following, which is a DoS attack?

Accepted Answer

Sending false requests nonstop to a targeted network.

Answer

A Denial of Service (DoS) attack aims to make a machine or network resource unavailable to its intended users. This is typically achieved by overwhelming the target system with a flood of traffic or requests, consuming its resources and preventing legitimate users from accessing the service. Sending nonstop false requests is a classic method to achieve this overload.
