ABSTRACT
At present, and maybe long into the future, it is impossible to be totally cyberse-cure, other than by going off the grid entirely. This chapter looks at the risks and how to address them, posed by cybersecurity threats to business and individuals. Cybersecurity is one risk to balance against others, requiring us to have some estimate of the costs of attacks. Section 5.2 looks at the cost of recent breaches. Threats come in many forms and attack different network levels (Section 7.7.1). Section 5.3 develops a taxonomy of the types of attack.
