Preventing password hacking

We have eight iSeries servers. We are planning to start our overseas operations. We do not want any hacking of passwords who will be logging overseas. For this we are planning to use password encryption. How should we implement this on servers? What procedure needs to be followed to do this activity?
Passwords are inherently encrypted on i5/OS. i5/OS user profile passwords are always encrypted – there is no option to store them in clear text as you have on other operating systems. However, there are certain cases during the log on process that they might be sent in cleartext. Therefore, if you are worried about network sniffing of passwords, you might consider having all sessions connecting to your servers be over an SSL connection.
