Which protocol is considered secure for managing network devices remotely?

1. Telnet

2. SSH

3. HTTP

4. RDP

The correct answer is: SSH

SSH, or Secure Shell, is recognized as a secure protocol for managing network devices remotely. It provides a secure channel over an unsecured network by using cryptography. When a user connects to a device using SSH, the connection is encrypted, which helps protect data from being intercepted during transmission. This is crucial for maintaining security, especially when managing network devices that may contain sensitive information or configurations. In contrast, protocols like Telnet and HTTP do not possess built-in encryption, leading to vulnerabilities where credentials and data can be easily intercepted by malicious entities. RDP, while secure when properly configured and used over a secure network, is primarily used for remote desktop connectivity rather than device management in a network context. SSH is also widely supported across various operating systems and network devices, making it a preferred choice for administrators looking to manage devices securely over the Internet or other potentially insecure networks.
