Which of the following is NOT a common attack vector?

• A. Ransomware
• B. Insider attacks
• C. Data redundancy
• D. Phishing

Answer: (C)

Data redundancy is described as the unnecessary duplication of data within a database or data storage system, which is typically a design issue rather than a security threat. It does not represent an active method used by attackers to compromise systems or data. On the other hand, ransomware, insider attacks, and phishing are all recognized attack vectors. Ransomware encrypts a user's data and demands payment for the decryption key, making it a significant threat to organizations. Insider attacks involve malicious actions taken by individuals within the organization, leveraging their access rights to exploit system vulnerabilities. Phishing involves tricking users into providing sensitive information, often by masquerading as a trustworthy source, which is a prevalent vector for data breaches. Thus, while ransomware, insider attacks, and phishing are direct methods utilized by malicious actors to exploit vulnerabilities, data redundancy does not fit within this category.
