This International Standard provides guidance on the integrated implementation of ISO/ IEC 27001 and ISO/ IEC 20000-1 for those organizations that are intending to either
a) implement ISO/ IEC 27001 when ISO/ IEC 20000-1 is already implemented, or vice versa,
b) implement both ISO/ IEC 27001 and ISO/ IEC 20000-1 together, or
c) integrate existing management systems based on ISO/ IEC 27001 and ISO/ IEC 20000-1.
This International Standard focuses exclusively on the integrated implementation of an information security management system (ISMS) as specified in ISO/ IEC 27001 and a service management system (SMS) as specified in ISO/ IEC 20000-1.
In practice, ISO/ IEC 27001 and ISO/ IEC 20000-1 can also be integrated with other management system standards, such as ISO 9001 and ISO 14001.
