This presentation is by two co-authors of the legal and ethics chapter of the recent authoritative textbook “Network Security Evaluation: Using the NSA IEM,” who have broad and deep experience in information security and privacy law, both in government and the private sector. They will provide unique insight into the coming clash between information security and privacy laws on either side of the Atlantic. The presentation will provide a comprehensive look at the evolving legal environment in which multi-national businesses and information security professionals must operate, and how conflicting laws can be successfully navigated to minimize liability and maximize protection of corporate assets. The presentation also will give an inside look at breaking developments in US national security and commercial law affecting multi-national businesses, as well as the privacy interests of Europeans and Americans. Finally, it will involve the audience in interactive discussions of several hypothetical—but all too potentially real—scenarios, to further illustrate the key points of the presentation.
