Book excerpt: "Sober, lucid and often wise." —Nature The Internet is powerful, but it is not safe. As "smart" devices proliferate the risks will get worse, unless we act now. From driverless cars to smart thermostats, from autonomous stock-trading systems to drones equipped with their own behavioral algorithms, the Internet now has direct effects on the physical world. Forget data theft: cutting-edge digital attackers can now literally crash your car, pacemaker, and home security system, as well as everyone else’s. In Click Here to Kill Everybody, best-selling author Bruce Schneier explores the risks and security implications of our new, hyper-connected era, and lays out common-sense policies that will allow us to enjoy the benefits of this omnipotent age without falling prey to the consequences of its insecurity.
