The trustworthiness of data or recourses in terms of preventing impr unauthorized changes: a) Integrity b) Non-Repudiation c) Attack motive d) vulnerability

Breakdown of the Problem

1. Identify the concepts related to data trustworthiness.
2. Analyze the options provided.

Relevant Concepts

• Integrity refers to the accuracy and reliability of data. It ensures that data remains unchanged unless authorized users modify it.
• Non-Repudiation ensures that a party cannot deny the authenticity of their signature on a message or the sending of a message itself.
• Attack Motive typically pertains to the reasons behind why an attacker might target a particular system.
• Vulnerability refers to weaknesses in a system that can be exploited to cause an unauthorized change or breach of data integrity.

Analysis and Detail

• The concept of integrity is directly related to preventing unauthorized changes to data, as it aims to ensure that the data remains intact and unaltered by unauthorized users.
• Non-repudiation, while related to authenticity, does not focus on data change prevention.
• Attack motives and vulnerabilities pertain to security and threats but do not directly address data integrity in terms of unauthorized changes.

Verify and Summarize

Based on the definitions and analysis:

• Option (a) Integrity is clearly the most relevant concept to preventing unauthorized changes to data.

Final Answer

a) Integrity
