Gary Hardy is coauthor of “Aligning Cobit, ITIL and ISO 17799 for Business Benefit: A Management Summary” Cobit is a high-level set of objectives with management and assurance tools for overall IT governance. ITIL, on the other hand, is mostly focused on service delivery and service management. Cobit has always been security-oriented, and at a high level sets out what should be done about security. Hardy: Security isn’t really what ITIL is focused on, it’s not its core strength.”]
