Hi All

In network audit we have got the below mentioned  comment from the auditor for cisco switches. can any one provide solution for the same.

SSH Protocol Version 1 Session Key Retrieval

The remote host is running a Telnet server over an unencrypted channel.
Using Telnet over an unencrypted channel is not recommended as logins, passwords, and commands are transferred in cleartext. This allows a remote, man-in-the-middle attacker to eavesdrop on a Telnet session to
obtain credentials or other sensitive information and to modify traffic exchanged between a client and server.
SSH is preferred over Telnet since it protects credentials from eavesdropping and can tunnel additional data streams such as an X11 session.
