Explanation
Strong encryption is the best defense against man-in-the-middle attacks because it renders intercepted data unreadable to the attacker even if traffic is captured.
Common mistakes.
- B. Fiber-optic cable is more difficult to physically tap than copper, but it is not impossible, and does not protect against logical MITM attacks on the network layer.
- C. A firewall controls traffic at network boundaries but does not encrypt data in transit and cannot prevent an attacker who is already positioned between the communicating parties.
- D. A strong password protects authentication credentials but does not protect the confidentiality or integrity of data transmitted over the network during a session.
