In its 4th edition, this book remains focused on increasing public awareness of the nature and motives of cyber vandalism and cybercriminals, the weaknesses inherent in cyberspace infrastructure, and the means available to protect ourselves and our society. This new edition aims to integrate security education and awareness with discussions of morality and ethics. The reader will gain an understanding of how the security of information in general and of computer networks in particular, on which our national critical infrastructure and, indeed, our lives depend, is based squarely on the individuals who build the hardware and design and develop the software that run the networks that store our vital information. Addressing security issues with ever-growing social networks are two new chapters: «Security of Mobile Systems» and «Security in the Cloud Infrastructure.»

在其第四版中，本书仍然专注于提高公众对网络破坏行为和网络犯罪分子的性质和动机的认识，网络空间基础设施的内在弱点，以及保护我们自己和社会的可用手段。这个新版本旨在将安全教育和意识与道德和伦理的讨论相结合。读者将了解到，我们的国家关键基础设施，乃至我们的生命所依赖的一般信息，特别是计算机网络的安全，是如何完全建立在建造硬件、设计和开发软件的个人身上的，而这些软件正是储存我们重要信息的网络。解决不断增长的社交网络的安全问题的是两个新章节。"移动系统的安全 "和 "云基础设施的安全"。
