The central truth is that information security, or "infosec," is a means, not an end. Ends justify themselves and also sometimes justify the means. Means, however, serve ends, and information security serves the end of trust. Trust is efficient, both in business and in life; and misplaced trust is ruinous, both in business and in life. Trust makes it possible to proceed where proof is lacking. As an end, trust is worth a price.
