D430 Fundamentals of Information Security - Set 1 - Part 3

Correct Answer: Man-in-the-middle attack

A man-in-the-middle attack occurs when a malicious actor intercepts communications between two parties, allowing them to steal or manipulate sensitive information without the knowledge of the parties involved.

Correct Answer: Biba Model

The Biba Model is focused on protecting data integrity by ensuring that only authorized individuals can modify information, even if it comes at the expense of confidentiality.

Correct Answer: Kismet

Kismet is a wireless network detection tool commonly used to discover wireless access points, even those that are hidden or have been configured to be difficult to detect.

Correct Answer: To detect and alert administrators of suspicious activity

Intrusion detection systems (IDS) are designed to monitor network or system activities and detect potential security threats or policy violations, alerting administrators to take action.

Correct Answer: Penetration testing

Penetration testing simulates the actions of attackers by using the same techniques they would employ to find and exploit security weaknesses, helping organizations assess the effectiveness of their defenses.

Correct Answer: Deep packet inspection firewall

Deep packet inspection (DPI) firewalls inspect the content of packets beyond just the headers, allowing them to detect and block more sophisticated attacks by analyzing the data being transmitted.

Correct Answer: Integrity

Integrity refers to ensuring that data remains accurate, complete, and unaltered by unauthorized parties, protecting it from unauthorized modification or tampering.

Correct Answer: Denial of Service (DoS)

A Denial of Service (DoS) attack overwhelms a network or system with excessive traffic, rendering it unavailable to legitimate users by exhausting its resources.

Correct Answer: To identify and analyze potential vulnerabilities and threats

A risk assessment involves identifying and evaluating vulnerabilities, threats, and risks to an organization's assets, allowing security teams to implement appropriate controls to mitigate those risks.

Correct Answer: Asymmetric cryptography

Asymmetric cryptography uses a pair of public and private keys to create digital signatures, ensuring the authenticity and integrity of messages by verifying the sender's identity.
