Certified Ethical Hacker (CEH v13) — Question 211

Jane is working as a security professional at CyberSol Inc. She was tasked with ensuring the authentication and integrity of messages being transmitted in the corporate network. To encrypt the messages, she implemented a security model in which every user in the network maintains a ring of public keys. In this model, a user needs to encrypt a message using the receiver’s public key, and only the receiver can decrypt the message using their private key.
What is the security model implemented by Jane to secure corporate messages?

Answer options

• A. Zero trust network
• B. Secure Socket Layer (SSL)
• C. Transport Layer Security (TLS)
• D. Web of trust (WOT)

Correct answer: D

Explanation

The correct answer is D, Web of trust (WOT), as it describes a decentralized model where users validate each other's public keys. Options A, B, and C refer to different security concepts or protocols that do not specifically relate to the model of using a collection of public keys for message encryption and decryption between users.
