'Tomorrow's infrastructure will be more complex as we move up the technology chain,' said Manuel Ravago, research manager at International Data Corporation (IDC) Philippines, during the 'Dynamic Resilience: Security and Continuity 2006' conference organized by IDC recently.

Ravago said that in today's Internet era, security is still more or less manageable, but we are also already grappling with threats. However, as technology advances -- such as radio frequency identification (RFID) and invisible computing -- security will be more complicated, he added.
