ITIL, the Information Technology Infrastructure Library, is a series of
volumes describing the best practices of IT service management.
The two major volumes are called 'ITIL Service Support', and ITIL Service
Delivery', each of which is categorized into a series of discrete
'disciplines' (one of which is security management).
ITIL itself was created and published by a department of the UK Government
known as the CCTA, which has since merged into the 'OGC' (Office of Government
Commerce). This body controls and 'owns' the standard, so strictly speaking,
it is not public domain.
Over the years ITIL has steadily evolved. Interest has also expanded
dramatically, such that it is now used all over the world, and is the major
framework for IT service management.
It is supported by a series of individual certifications: foundation,
manager and practitioner. A whole industry has emerged to support this.
ISO 20000 is the emerging standard for IT service management. It aligns and compliments ITIL, and is the direct replacement for BS15000, which will gradually be withdrawn.
