In recent years, we have witnessed many information security developmental trends. As a consequence, the dimensions of information security — once a single disciplinary area — have become multifaceted and convoluted. This paper aims to (1) recapitulate these key developments; (2) argue that the emergence of many complex information security dimensions are the result of ?constant change agents? (CCAs); (3) discuss the implications on Australia?s society, i.e. Government, companies and individuals; and (4) propose key consideration areas and possible solutions thereof. We hope that the discussion presented here will position Australia to make better aligned information security and strategic plans, such as choosing appropriate investments and adopting effective solutions to strengthen and secure Australia?s national information security posture.
