Cybersecurity and Cyberwar: What Everyone Needs to Know

by Peter Friedman and Allan Singer | | Kindle | Worldwide (free shipping)

Cybersecurity and Cyberwarfare provides a clear explanation of the types of Internet and computer-based threats that can face countries. Friedman and Singer do a good job of explaining not only the potential damage that could be done by cyberintrusions, but also how technology can - as is - being used as a weapon of war by powers such as the US (Stuxnet is covered in detail). There is also a good discussion of why it is so hard to defend computers and infrastructure against cyber attacks.

The book focuses primarily on miltiary (Politics and Government) but many of the issues and problems are equally applicable to the realm of Business and Employment, and the examples are an excellent basis for discussions about the future of cyberwarfare and the ethics of using technology in this way.
