Walling Out the Insiders [PDF ebook] 
Controlling Access to Improve Organizational Security

Insider threats are everywhere. To address them in a reasonable manner that does not disrupt the entire organization or create an atmosphere of paranoia requires dedication and attention over a long-term. Organizations can become a more secure, but to stay that way it is necessary to develop an organization culture where security concerns are inherent in all aspects of organization development and management. While there is not a single one-size-fits-all security program that will suddenly make your organization more secure, this book provides security professionals and non-security managers with an approach to protecting their organizations from insider threats.
