How does Telnet differ from SSH?

Telnet and SSH are both protocols used for remote access to computers, but they differ in terms of security and encryption.

Telnet:

• Uses plain text communication, which means data is not encrypted and can be intercepted by eavesdroppers.
• Does not require authentication, making it a security risk for sensitive information.
• Generally faster and simpler to use compared to SSH.

SSH (Secure Shell):

• Uses encryption to secure communication between the client and server, protecting data from being intercepted.
• Requires authentication using a username and password or public/private key pair, enhancing security.
• Considered more secure for remote access and file transfers over untrusted networks.

In summary, Telnet lacks security measures compared to SSH, making SSH the preferred choice for secure remote access to systems.
