On March 18, 2013, internet users worldwide felt the consequences of a massive cyber-attack. The biggest in history, the Distributed Denial-of-Service Attack (DDoS) of 300Gbps started as a retaliation from the hosting server Cyber Bunker against the anti-spam organisation Spamhaus. The attack not only caused disturbances to Spamhaus and its hosts and partners, but also slowed down internet connection internationally, most notably in the UK, Germany and other parts of Western Europe. In recent years, cyber security concerns have spread to different areas of life, with discussions over the impact of threats and need for resilience receiving growing media attention and significant government investments. This article examines the status of the cyber security debate in Europe, conflicts of interest in the private sector and perspectives from civil society.
