Authored by Professor Ross Anderson, Why Information Security is Hard applies an economic analysis to explain the many vulnerabilities within the field of information security.

"According to one common view, information security comes down to technical measures. Given better access control policy models, formal proofs of cryptographic protocols,approved �rewalls, better ways of detecting intrusions and malicious code, and better tools for system evaluation and assurance, the problems can be solved.
In this note, I put forward a contrary view: information insecurity is at least as much due to perverse incentives. Many of the problems can be explained more clearly and convincingly using the language of microeconomics: network externalities, asymmetric information, moral hazard, adverse selection, liability dumping and the tragedy of the commons."
