The document discusses implementing an integrated IT service management system (SMS) and information security management system (ISMS) based on ISO/IEC 20000-1 and ISO/IEC 27000 standards. It describes how ISO/IEC 27001 fits into the information security requirements of ISO/IEC 20000. There are key benefits to an integrated system, including providing credible and secure services, lower implementation costs, reduced timelines by developing common processes together, and eliminating duplication between the standards. An integrated system also promotes understanding between service and security personnel.
