ITIL (IT Infrastructure Library), is a set of concepts and techniques for managing information technology (IT) infrastructure, development, and operations. It is heavily influenced by a set of documents published by IBM in the 1980s, referred to as the Yellow Books. ITIL emerged from a body of work done by the UK Government (OGC) to solve Information Technology Management issues.

The following information gives a brief account of relevant components of the ITIL standard. Each requirement of the standards are broken down further into more specific sub-requirements that can be mapped back to both the Security Principles that drive them and the Design Patterns that satisfy them.


Standards Outline

The ITIL v3 framework, published in May 2007, involves five key concepts;

  • 1. Service Strategy
  • 2. Service Design
  • 3. Service Transition
  • 4. Service Operation
  • 5. Continual Service Improvement

ITIL framework

The components of ITIL in more detail are:

  • Service Strategy focuses on the identification of market opportunities for which services could be developed in order to meet a requirement on the part of internal or external customers. The output is a strategy for the design, implementation, maintenance and continual improvement of the service as an organizational capability and a strategic asset. Key areas of this volume are Service Portfolio Management and Financial Management.
  • Service Design focuses on the activities that take place in order to develop the strategy into a design document which addresses all aspects of the proposed service, as well as the processes intended to support it. Key areas of this volume are Availability Management, Capacity Management, Continuity Management and Security Management.
  • Service Transition focuses on the implementation of the output of the service design activities and the creation of a production service or modification of an existing service. There is an area of overlap between Service Transition and Service Operation. Key areas of this volume are Change Management, Release Management, Configuration Management and Service Knowledge Management.
  • Service Operation focuses on the activities required to operate the services and maintain their functionality as defined in the Service Level Agreements with the customers. Key areas of this volume are Incident Management, Problem Management and Request Fulfillment.
  • Continual Service Improvement focuses on the ability to deliver continual improvement to the quality of the services that the IT organization delivers to the business. Key areas of this volume are Service Reporting, Service Measurement and Service Level Management.
