Das Thema Cybersecurity ist so aktuell wie nie, denn im Cyberspace lassen sich nur schwer Grenzen in Bezug auf den Zugang zu Informationen, Daten und Redefreiheit setzen. Kriminelle nutzen die Lücken oft zu ihrem Vorteil aus. Die Vielzahl der IT-Systeme, ihre unterschiedlichen Nutzungsarten und ihre Innovations- und Lebenszyklen haben zu hohen Sicherheitsrisiken für Unternehmen und staatliche Einrichtungen geführt. Diese Risiken werden sich auch langfristig nicht so einfach aus der Welt schaffen lassen. Daher müssen Institutionen Strategien und Lösungen zu ihrem Selbstschutz entwickeln. Dieses Buch beschreibt Lösungsansätze und Best Practices aus den unterschiedlichsten Bereichen, die nachweislich zu einer höheren Resilienz gegenüber Cyberangriffen führen. Weltweit renommierte IT-Sicherheitsexperten berichten in 40 Beiträgen, wie sich staatliche Institutionen, unter anderem das Militär (Cyber Defence), Behörden, internationale Organisationen und Unternehmen besser gegen Cyberangriffe schützen und nachhaltige Schutzstrategien entwickeln können. Die Autoren widmen sich den Gründen und Zielen, die ihren jeweiligen Strategien zugrunde liegen, sie berichten, wie Unternehmen auf konkrete Cyberattacken reagiert haben und wie einzelne staatliche Institutionen angesichts nationaler Cyberstrategien agieren. In weiteren Kapiteln zeigen Wissenschaftler auf, was bei der Abwehr von Cyber-Attacken bereits heute möglich ist, welche Entwicklungen in Arbeit sind und wie diese in Zukunft eingesetzt werden können, um die Cyber-Sicherheit zu erhöhen. Im letzten Kapitel berichten Hersteller, Anwenderunternehmen und Dienstleister welche Best Practices sie in ihren Unternehmen eingeführt haben und wie andere Unternehmen ihrem Beispiel folgen können. Das Buch richtet sich an IT-Verantwortliche und -Sicherheitsbeauftragte in Unternehmen und anderen Organisationen, aber auch an Studierende in den verschiedenen IT-Studiengängen.

A generation ago, "cyberspace" was just a term from science fiction, used to describe the nascent network of computers linking a few university labs. Today, our entire modern way of life, from communication to commerce to conflict, fundamentally depends on the Internet. And the cybersecurity issues that result challenge literally everyone: politicians wrestling with everything from cybercrime to online freedom; generals protecting the nation from new forms of attack, while planning new cyberwars; business executives defending firms from once unimaginable threats, and looking to make money off of them; lawyers and ethicists building new frameworks for right and wrong. Most of all, cybersecurity issues affect us as individuals. We face new questions in everything from our rights and responsibilities as citizens of both the online and real world to simply how to protect ourselves and our families from a new type of danger. And yet, there is perhaps no issue that has grown so important, so quickly, and that touches so many, that remains so poorly understood. In Cybersecurity and CyberWar: What Everyone Needs to Know®, New York Times best-selling author P. W. Singer and noted cyber expert Allan Friedman team up to provide the kind of easy-to-read, yet deeply informative resource book that has been missing on this crucial issue of 21st century life. Written in a lively, accessible style, filled with engaging stories and illustrative anecdotes, the book is structured around the key question areas of cyberspace and its security: how it all works, why it all matters, and what can we do? Along the way, they take readers on a tour of the important (and entertaining) issues and characters of cybersecurity, from the "Anonymous" hacker group and the Stuxnet computer virus to the new cyber units of the Chinese and U.S. militaries. Cybersecurity and CyberWar: What Everyone Needs to Know® is the definitive account on the subject for us all, which comes not a moment too soon.

Read the book written by the subject of the bestseller 'Breaking and Entering: The Extraordinary Story of a Hacker Called "Alien" ' Why do some organizations emerge from a data breach unscathed, while others are badly damaged, or even collapse? How can you make smart choices to protect your organization before and after a data breach? This book exposes the high-octane world of data breach disclosure and response, where IT help desk staff have the power to save or destroy a company, and cutting-edge attorneys must often parachute in to save the day. You'll watch as one of the world's most experienced cybersecurity professionals dissects high-profile data breaches, reveals what happened, and reveals exactly what you can do to navigate a massive data breach -- quickly mitigating damage to your digital assets, finances, and organizational reputation. Sherri Davidoff teaches through storytelling, making this book powerfully accessible and practically useful to everyone from the boardroom to the server closet. Along the way, she reveals what the press didn't cover about attacks on ChoicePoint, TJ Maxx, Heartland, Target, Anthem, and many other leading organizations -- and presenting specific lessons you can start applying right now, regardless of your technical or business infrastructure. Drawing on her immense personal experience with digital forensics, incident response, security awareness training, penetration testing, and web security assessment -- and her work teaching in venues from Black Hat to the Department of Defense -- Davidoff introduces today's most comprehensive and practical framework for data breach response. You'll discover: Critical turning points throughout data breach events, and how to respond to each of them How breach response lifecycles are changing: why classic incident response approaches are no longer sufficient, and what to do instead How internal politics can affect data breach response, and what to do about it How to read between the lines of public statements and notifications (or lack thereof) What you need to know about breaches in retail and other specific industries -- and the limitations of standards such as PCI/DSS How to protect against and recover from ransomware How to assess products and services such as Commercial Off-The-Shelf Breach Response, cybersecurity insurance, and crisis management services What you can do right now to make breach response less traumatic
