European cyber security experts have stressed the importance of involving the private sector in any plans to strengthen critical infrastructure against cyber attack.
The European Network and Information Security Agency (Enisa) said it will "strongly support" nation states' individual efforts to tackle the latest security threats, following a successful security exercise last month.
"The Cyber Europe 2010 exercise fully met its objectives to test Europe's readiness to face online threats to essential critical infrastructure used by citizens, governments and businesses," said Udo Helmbrecht, executive director at Enisa.
"We will work closely with member states to identify and implement the lessons learnt from this exercise. We also encourage member states to continue their efforts in the area of exercises at national and pan-European levels."
Helmbrecht claimed that the exercise met all of its objectives, but exposed weaknesses such as a lack of Pan-European standards for use in testing, which could present problems with how actual incidents are managed.
More time will be spent planning attacks in the future, according to Enisa, which is where the private sector is likely to become involved.
Helmbrecht said that 30 European countries were involved in the test, 22 actively taking part and eight observing.
Enisa will continue to evaluate its findings, and expects to release reports about specific country responses and preparedness at a later date. A full report will be released early next year.
