Over recent years I've become increasingly focused on connecting IBM i Systems to the Internet - aka cloud for you trendy peeps. We live in an internet connected world and the requirements for business to plug their back office Power Servers into this big cloud is rapidly becoming a standard.
With the huge increase in mobile development and webservice focused business even IT Departments that have never thought about internet connection are now considering the consequences.
This leads to many of my customers asking me the same question:
HOW SECURE IS IBM I (AS400/iSERIES) INTERNET CONNECTION?
