I have configured Core FTP mini-sftp application in my server to use SFTP. I observe some unknown IP's connecting to my server in the connected list. By tracing the ips I found they are some chinese and thai websites. I use JSCH to connect SFTP. Suggest me on how to avoid these IP address connecting and make secure.
