The Executive Director of ENISA, Dr Udo Helmbrecht, comments: “Stuxnet is really a paradigm shift, as Stuxnet is a new class and dimension of malware. Not only for its complexity and sophistication, e.g. by the combination of exploiting four different vulnerabilities in Windows, and by using two stolen certificates, and from there attacking complex Siemens SCADA systems. The attackers have invested a substantial amount of time and money to build such a complex attack tool. The fact that perpetrators activated such an attack tool, can be considered as the „“first strike““, i.e. one of the first organized, well prepared attack against major industrial resources. This has tremendous effect on how to protect national (CIIP) in the future. After Stuxnet, the currently prevailing philosophies on CIIP will have to be reconsidered. They should be developed to withstand these new types of sophisticated attack methods. Now, that Stuxnet and its implemented principles have become public, we may see more of these kinds of attacks. All security actors will thus have to be working more closely together and develop better and more coordinated strategies.” Dr Helmbrecht concludes. How ENISA supports the Member States to prepare for attacks on critical information infrastructure Large scale attacks on Critical Information Infrastructure needs a coordinated reaction, involving the key players from both public and private sector. No Member State, hardware/software vendor, CERT or law enforcement agency can successfully mitigate sophisticated attacks like Stuxnet on their own. ENISA, as an EU body of expertise in Network and Information Security (NIS), is supporting the European Commission’s CIIP action plan. This involves working closely with the Member States, public and private sector stakeholders’ to secure Europe’s Critical Information Infrastructure. ENISA’s Resilience and CIIP program helps the Member States and private sector to develop good practices in a number of areas relating to the protection of Critical Information Infrastructure. These include combating botnets, improving the security of interconnected networks and reporting major security incidents. In 2011, ENISA will support the development of good practices in securing SCADA systems and analyse dependencies of critical sectors to Information and Communication Technologies. ‚CYBER EUROPE 2010‘ 1st Pan European cyber security Exercise In addition ENISA, in co-operation with all EU Member States and 3 EFTA countries, is coordinating the first CIIP pan cyber security European exercise, the ‚CYBER EUROPE 2010‘. This exercise will test Member States’ plans, policies and procedures for responding to potential CIIP crises or incidents, such as ‘Stuxnet’. Reinforcing ‚digital firebrigades‘; CERTs ENISA is also active in reinforcing national/governmental ‚digital firebrigades‘ i.e. Computer Emergency Response Teams, or CERTs, by supporting the Member States with the setting-up, training and exercising of incident response capabilities. Together, we define a set of baseline capabilities all teams should exhibit. We also work on enhancing capabilities in e.g. cross-border cooperation, Early Warning, and cooperation with law enforcement. ENISA actively supports a coordinated reaction to large scale attacks, and will (if called upon) willingly take its role as coordinator and facilitator for appropriate counter measures. www.enisa.europa.eu
