European Network and Information Security Agency (ENISA) Issues Cloud Computing Guidance

 The European Network and Information Security Agency (ENISA) has just published a paper on cloud computing, which discusses the benefits and risks of cloud computing from a security perspective. The paper also includes recommendations for improving information security in the context of cloud computing and provides a - in our view very helpful - set of questions that organizations can use to assess whether or not providers of cloud computing services are sufficiently protecting the data entrusted to them.

The key conclusion of the paper is that the “cloud’s economies of scale and flexibility are both a friend and a foe from a security point of view. The massive concentrations of resources and data present a more attractive target to attackers, but cloud-based defenses can be more robust, scalable and cost-effective.” 

The paper is particularly timely in light of the European Commission’s public consultation on the legal framework for the fundamental right to protection of personal data, which closes at the end of next month. ENISA’s paper includes specific recommendations for the European Commission’s future consideration. It rightfully points out that certain issues related to the EU Data Protection Directive and Article 29 Working Party recommendations warrant clarification. In the current legal framework, it is not clear, for example, under which circumstances a provider of cloud computing services may be classified as a “joint controller” of personal data. ENISA also recommends that the European Commission examine and clarify, inter alia:

-         whether providers of cloud computing services should be obliged to notify their customers of data security breaches (and what information should be provided to these customers);

-         the legal impact of data transfers to providers of cloud computing services in countries outside the European Economic Area (EEA), if those countries do not provide an “adequate” level of data protection;

-         how the intermediary liability exemptions arising from the eCommerce Directive apply to providers of cloud computing services.

As far as information security in concerned, ENISA’s paper provides useful and practical guidance for potential and existing users of cloud computing services as well as policy makers. It will be interesting to see to what extent its recommendations will result in concrete action by the European Commission and/or Article 29 Working Party.

French CNIL Issues Data Security Tips

On October 12, 2009 the CNIL issued ten recommendations for companies to help protect their data.  The recommendations are fairly basic, ranging from implementing a rigorous password policy to ensuring that only authorized personnel have access to the company’s computer room.  The recommendations have an important pedagogical role, however, and illustrate that the CNIL is broadening its scope of focus from its traditional role of defining under what conditions personal data can be processed in France to dealing with the results of that processing,  in particular focusing on the prevention of data breaches. 

For those familiar with the security recommendations issued by ENISA, the European Network and Information Security Agency, the CNIL’s recommendations may seem quite rudimentary in comparison.   ENISA has issued a number of detailed recommendations on data security, and it is unfortunate that the CNIL did not refer to the excellent ENISA work in this area.   See, for example, ENISA's 2009 papers "10 Security Awareness Good Practices" and "Information Security Awareness in Financial Organizations - Guidelines and Case Studies."   However, the CNIL's recommendations may only be a first step, and it will be interesting to see whether the CNIL's guidance evolves as concern about data breaches continues to grow.
