Which core publication will you find detailed descriptions of service catalog management, information security and support management?

Service Strategy focuses on strategic positioning, service portfolio management, and financial management at a high level, not detailed operational process descriptions.

Service Design is the core ITIL publication that provides detailed coverage of processes needed to design services for the live environment, explicitly including service catalog management, information security management, capacity management, availability management, and supplier management. These processes ensure services are designed to meet agreed requirements before transition into production.

Service Transition covers processes such as change management, release and deployment management, and knowledge management for moving services into the live environment.

Service Operation covers day-to-day processes such as incident management, problem management, event management, and request fulfillment.
