Cybersecurity as a global issue

Cybersecurity is not a parochial issue concern just the organisation. The threats and problems occur on a global scale, from groups in China and Russia, for example. We also face possibility of cyberwarfare. Cybercrime is also a major issue. Denial of service attack, phishing and a number of issue are global concerns.Cyber security is now a Board level issue for many companies, and one that lawyers advising the Board must understand. But how much do we really know about this increasing risk?

Question: Provide a definition of cybersecurity. Identify some key threats and issues which have a global dimension. Give some case studies looking at both the sources and the victims. Identify areas where you think UK companies need to respond. What is the role of ISPs in cybersecurity? How significant is the threat from national security services? To what extent is the dark net something that should concern IT managers or can we just ignore it?
