Discussion

This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to eavesdropping, potentially putting sensitive data (including administrator passwords) at risk of compromise and potentially allowing hijacking of maintenance sessions.

Fix Text

Configure the Cisco IOSISR XE4000 Series router to use SSHv2 for remote access. The configuration should look like the example below: ip ssh version 2 ! line vty 0 98 transport input ssh
