Organizations with computer networks, Web sites, and employees carrying laptops and Blackberries face an array of security challenges. Among other things, they need to keep unauthorized people out of the network, thwart Web site hackers, and keep data safe from prying eyes or criminal hands.

This book provides a high-level overview of these challenges and more. But it is not for the hard-core IT security engineer who works full time on networks. Instead, it is aimed at the nontechnical executive with responsibility for ensuring that information and assets stay safe and private. Written by a practicing information security officer, Philip Alexander, the book contains the latest information and arms readers with the knowledge they need to make better business decisions.
