Certified Ethical Hacker (CEH v11) — Question 331

Peter, a system administrator working at a reputed IT firm, decided to work from his home and login remotely. Later, he anticipated that the remote connection could be exposed to session hijacking. To curb this possibility, he implemented a technique that creates a safe and encrypted tunnel over a public network to securely send and receive sensitive information and prevent hackers from decrypting the data flow between the endpoints.
What is the technique followed by Peter to send files securely through a remote connection?

Answer options

• A. VPN
• B. SMB signing
• C. DMZ
• D. Switch network

Correct answer: A

Explanation

The correct answer is VPN, as it creates a secure and encrypted tunnel for data transmission over public networks, effectively protecting against session hijacking. SMB signing is a method used to ensure the integrity of SMB communications but does not encrypt data over public connections. DMZ refers to a network segment for added security but does not provide encryption for remote connections. A switch network is a type of network device and does not relate to secure data transmission methods.
