D430 Fundamentals of Information Security - Set 5 - Part 3

Correct Answer: Nonrepudiation

Nonrepudiation ensures that a user cannot deny having performed a specific action, such as sending a message or making a transaction, providing proof of the action.

Correct Answer: Hashing

Hashing generates a fixed-length output (hash) from an input message, which can be used to verify the integrity of the data by detecting any unauthorized changes.

Correct Answer: Competitive intelligence

Competitive intelligence involves gathering and analyzing public information about competitors to support business decisions, often through legal methods such as public reports and market analysis.

Correct Answer: SQL Injection

SQL Injection attacks exploit web applications' failure to properly validate user inputs, allowing attackers to insert unauthorized SQL code and manipulate the backend database.

Correct Answer: Principle of Least Privilege

The Principle of Least Privilege restricts user access to the minimum permissions required to perform their job duties, reducing the risk of accidental or malicious misuse of data.

Correct Answer: Intrusion Detection System (IDS)

An Intrusion Detection System (IDS) passively monitors network traffic and alerts administrators when suspicious activity is detected, helping to identify potential security incidents.

Correct Answer: Hashing

Hashing generates a unique, fixed-length value from an input message, ensuring data integrity by detecting any changes that may have occurred to the original message.

Correct Answer: Honeypot

A honeypot is a decoy system set up to attract attackers, allowing administrators to monitor and analyze attack techniques without risking the integrity of actual systems.

Correct Answer: Eradication

Eradication involves removing the root cause of a security breach, such as malware or compromised accounts, ensuring that the threat is fully eliminated from the system.

Correct Answer: Vulnerability scanner

A vulnerability scanner scans systems for known vulnerabilities and provides recommendations for patching or mitigating them, helping organizations address potential security risks.
