Book excerpt: Emerging alongside the widespread adoption of networked information technologies, cybersecurity incidents represent a significant threat to our common well-being. The institutional construct of a Computer-Emergency Response Team (CERT) began to evolve thirty years ago as a response to security incidents in the nascent Internet. This book, Next Generation CERTs, presents papers arising from the NATO Advanced Research Workshop “New Generation CERT: from Response to Readiness - Strategy and Guidelines”, held in Chiavari, Italy, from 28 - 30 March 2017. The workshop enabled 38 leading experts from NATO members and affiliate states to discuss the limitations of current CERTs and identify the improvements that are likely to shape the CERTs of the future. After the workshop, participants were invited to submit the papers included here. The book is divided into 3 main sections: state of the art; next generation CERTs; and the experience of CERTs. A number of approaches are covered – technical, tactical, strategic – which could be applied to both civilian and military environments. Providing an insight into the likely future development of CERTs, the book will be of interest to all those involved in the field of cybersecurity.
