Varnost komunikacijskih omrežij in informacijskih sistemov, zlasti njihova razpoložljivost, zato postaja vedno večja skrb družbe, nenazadnje zaradi možnih težav v ključnih informacijskih sistemih, ki so posledica kompleksnosti sistema, nesreč, napak in neupravičenih posegov, ki lahko vplivajo na fizične infrastrukture, ki opravljajo storitve, bistvene za dobrobit državljanov EU.
The security of communication networks and information systems, in particular their availability, is therefore of increasing concern to society not least because of the possibility of problems in key information systems, due to system complexity, accidents, mistakes and attacks, that may have consequences for the physical infrastructures which deliver services critical to the well-being of EU citizens.
