What are the differences between SSH and Telnet protocols in terms of security, and what are the steps involved in configuring SSH on a Cisco device for secure remote access?
Secure Shell (SSH) and Telnet are both network protocols used for remote access to devices, but they differ significantly in terms of security. Telnet is an older protocol that transmits data, including passwords, in plain text, making it highly vulnerable to eavesdropping and man-in-the-middle attacks. In contrast, SSH provides a secure channel over an unsecured
