What feature of SSH makes it more secure than Telnet for a device management connection?
- confidentiality with IPsec
- stronger password requirement
- random one-time port connection
- login information and data encryption
Answers Explanation & Hints:
Secure Shell (SSH) is a protocol that provides a secure management connection to a remote device. SSH provides security by providing encryption for both authentication (username and password) and the transmitted data. Telnet is a protocol that uses unsecure plaintext transmission. SSH is assigned to TCP port 22 by default. Although this port can be changed in the SSH server configuration, the port is not dynamically changed. SSH does not use IPsec.
