FREE IT Cybersecurity Principles & Protocols Questions and Answers

Question 1

What does the CIA triad stand for in cybersecurity?

Accepted Answer

Confidentiality, Integrity, Availability

Answer

The CIA triad stands for Confidentiality, Integrity, and Availability, which are the three core principles of information security. Confidentiality ensures data is accessible only to authorized individuals, Integrity ensures data remains accurate and unaltered, and Availability ensures authorized users can access information and systems when needed. These pillars guide the development of robust security policies and practices.

Question 2

Which type of malware disguises itself as legitimate software?

Accepted Answer

Trojan

Answer

A Trojan, or Trojan horse, is a type of malware that disguises itself as legitimate or useful software to trick users into installing it. Once executed, it can perform malicious actions such as stealing data, creating backdoors, or installing other malware, without the user's knowledge. Unlike viruses, Trojans do not self-replicate but rely on deception for distribution.

Question 3

What is phishing?

Accepted Answer

Social engineering attack

Answer

Phishing is a type of social engineering attack where attackers attempt to trick individuals into revealing sensitive information, such as usernames, passwords, and credit card details. This is typically achieved by impersonating a trustworthy entity through deceptive emails, messages, or websites that appear legitimate. Phishing exploits human psychology rather than technical vulnerabilities to gain unauthorized access.

Question 4

Which tool monitors network traffic for suspicious activity?

Accepted Answer

IDS

Answer

An IDS (Intrusion Detection System) is a security tool that monitors network traffic and system activities for malicious activity or policy violations. It detects suspicious patterns or known attack signatures and alerts administrators to potential threats. While a firewall blocks traffic, an IDS focuses on identifying and reporting intrusions that may have bypassed other defenses.

Question 5

What is the purpose of multi-factor authentication (MFA)?

Accepted Answer

Enhance security

Answer

Multi-factor authentication (MFA) significantly enhances security by requiring users to provide two or more verification factors to gain access to an account or system. This typically combines something the user knows (password), something the user has (phone, token), and/or something the user is (biometrics). This layered approach makes it much harder for unauthorized individuals to access accounts, even if one factor is compromised.
