SSH and Secure File Transfer

FTP and Telnet are insecure ways of accessing remote systems on the network. Hackers can snip the data passed between computers during FTP/Telnet connections. In particular, they can read a user’s password when one logins a remote system.

For data protection, you are recommended to use a secure way for data transfer called SSH (Secure Shell)/SFTP (Secure File Transfer Protocol). SSH/SFTP is designed as a replacement for Telnet and is the standard for secure file transfer and remote logins over the Internet.  All network traffic is encrypted and optionally compressed to support strong authentication measures for secure communications.

You are advised to use SSH/SFTP client program to access the following remote systems of ITS:
