The purpose of this guide is to increase awareness of the need for high security
in industrial information and control systems. The guide shall also serve as a
concrete support for those working within critical infrastructure.
The first edition of this guide was published in 2008 and has re ceived a wide
distribution, both nationally and internationally. It has also become standard in
many sectors. With this third edition, the document’s name has been changed to
Guide to Increased Security in Industrial Information and Control Systems. Through this
name change, we would like to emphasise the increasing dependency between
process IT and administration IT.
