33 ?What is the advantage of using SSH over Telnet?
SSH provides secure communications to access hosts.
SSH supports authentication for a connection request.
SSH operates faster than Telnet.
SSH is easier to use.
The correct answer and explanation is:
The correct answer is:
SSH provides secure communications to access hosts.
Explanation:
Secure Shell (SSH) and Telnet are both network protocols used to connect to remote systems, but SSH has significant advantages over Telnet, primarily due to its security features.
- Encryption & Security:
The biggest advantage of SSH over Telnet is that SSH encrypts all communication between the client and the server. Telnet, on the other hand, transmits data, including passwords, in plaintext, making it vulnerable to interception by attackers using packet sniffers. SSH uses encryption algorithms like AES (Advanced Encryption Standard) and RSA to ensure confidentiality. - Authentication & Integrity:
SSH provides strong authentication mechanisms, including public-key authentication, which enhances security. It also ensures data integrity using hashing algorithms such as SHA (Secure Hash Algorithm), preventing tampering of transmitted data. In contrast, Telnet does not verify whether the data was altered during transmission. - Remote Command Execution:
SSH allows users to execute commands on a remote system securely, just like Telnet. However, SSH adds an extra layer of protection, preventing unauthorized access and ensuring that all data exchanged remains confidential. - Tunneling and Port Forwarding:
SSH can be used to create secure tunnels to forward other types of traffic (such as HTTP, FTP, and even remote desktop connections), whereas Telnet does not support tunneling or port forwarding, making it less versatile. - Widely Used in Secure Networks:
Due to its robust security, SSH is the standard protocol for remote administration of servers in enterprise environments, while Telnet is generally discouraged due to its security vulnerabilities.
In conclusion, SSH is the preferred choice over Telnet because it ensures secure and encrypted communication, protecting sensitive data from cyber threats.
Now, I will generate an image related to SSH security.
Here is an image illustrating the security benefits of SSH over Telnet. It visually represents encrypted data streams with a secure lock, while showing an insecure Telnet connection with exposed data packets. Let me know if you need any modifications!
