PWS: Clearly the number of attacks will go up; indeed, we're discovering 9 new pieces of malware every second. But in the book we try to look beyond these astronomical, but also sometimes meaningless numbers, to key trends. One, for example, is the shift to different uses and users, such as the move towards more mobile devices (and threats towards them). Moreover, the Internet is no longer just about sending or compiling information online, it shapes the real world via the emerging Internet of Things. Indeed, Cisco believes the number of Internet-enabled devices will rise to 40 billion over the next 5 years, as cars, fridges, medical devices, and gadgets not yet imagined or invented all link in. But these in turn will be targeted with different consequences that say defacing a website. For instance, PopSci has explored the move toward Internet-enabled cars and even driverless cars and the drone boom. Well, we're also seeing the move towards "car-hacking" and "drone-hacks."
