Question

Which security drawback involves a user denying a transaction they were involved in?

• A. Spoofing
• B. Repudiation
• C. Denial of Service (DoS) Attacks
• D. Unauthorized Information Disclosure

Answer 1

Answer:

B. Repudiation

• Denial of Involvement: Repudiation is the act of a user falsely claiming they did not participate in a transaction or activity. For instance, a person might deny making an online payment or sending a particular message.

• Lack of Trust: This problem arises when there's no way to definitively prove the user's involvement, which breaks trust in the system. It's a significant security concern, especially in financial transactions and legal documents.

• E-governance Solution: To combat repudiation, e-governance systems use security measures like digital signatures and audit trails. These technologies provide irrefutable proof of a user's action, ensuring accountability and preventing them from denying a transaction later.
