Security Awareness: Brave New World

Computer security is a challenge. An attacker only needs to find one hole…but a defender needs to close all holes. Since it is impossible to close all holes, you can only hope to close most holes, layer defenses (like you layer clothes when going out in the freezing cold), and hope that the intruder will find an easier target elsewhere. This chapter is about educating yourself about malware, hacking and the motives of computer attackers, and how to start to defend the simplest of devices: your mobile and home computers.
