This book is the direct result of the outstanding efforts of a talented pool of security analysts, editors, business leaders and security professionals, all of whom work for iDefense® Security Intelligence Services; a business unit of VeriSign, Inc.

iDefense is an open-source, cyber security intelligence operation that maintains expertise in vulnerability research and alerting, exploit development, malicious code analysis, underground monitoring and international actor attribution. iDefense provides intelligence products to Fortune 1,000 companies and "three-letter agencies" in various world governments. iDefense also maintains the Security Operations Center for the Financial Sector Information Sharing and Analysis Center (FS-ISAC); one of 17 ISACs mandated by the US government to facilitate information sharing throughout the country’s business sectors.

iDefense has the industry-unique capability of determining not only the technical details of cyber security threats and events (the "what", the "when" and the "where"), but because of their international presence, iDefense personnel can ascertain the most likely actors and motivations behind these attacks (the "who" and the "why").
