200-201 Question 170
Single answerA security analyst is tasked with configuring a secure connection between a client and a server using SSH. Upon reviewing the client's SSH configuration, the analyst notices that it is set to use SSH version 1. Why is it important to update the configuration to use SSH version 2?
- A
SSH version 2 offers improved encryption algorithms, making the connection more secure.
- B
SSH version 1 is no longer supported by modern operating systems and devices.
- C
SSH version 2 uses a more efficient key-exchange mechanism, reducing latency in sessions.
- D
SSH version 1 is vulnerable to man-in-the-middle (MITM) attacks due to its flawed design.
Show answer and explanation
Correct answer: A
Explanation
SSH version 1 has known security vulnerabilities and lacks the robust encryption algorithms and features introduced in SSH version 2. Upgrading to SSH version 2 ensures the use of secure, modern cryptographic methods that protect against various attacks, including eavesdropping and unauthorized access.
- A. Correct.
Correct. SSH version 2 provides enhanced security features, including improved encryption algorithms, making it significantly more secure than SSH version 1.
- B. Incorrect.
Incorrect. While modern systems may discourage the use of SSH version 1, this is not the primary reason for upgrading to SSH version 2.
- C. Incorrect.
Incorrect. Although SSH version 2 may use different key-exchange mechanisms, the focus of its adoption is primarily on improved security rather than performance.
- D. Incorrect.
Incorrect. While SSH version 1 has security flaws, the specific vulnerability to MITM attacks is not the main reason to prefer SSH version 2.
