This collection of essays on security: on security technology, on security policy, and on how security works in the real world was previously published between June 2002 and June 2008. They offer a computer security expert's insights into a wide range of security issues, including the risk of identity theft (vastly overrated), the long-range security threat of unchecked presidential power, why computer security is fundamentally an economic problem, the industry power struggle over controlling your computer, and why national ID cards won't make us safer, only poorer. Schneier recognizes that the ultimate security risk is people and that many security paractices are, in fact, secuirty risks. -- From publisher description.
