Trust Relationships

Trust relationships are foundational to most IT network and database systems. They are the framework that determines how different systems or users can access data and interact with other systems on the network. When two different systems want to share data or resources, a trust relationship allows authentication and authorization to occur so that data can be shared without requiring the user to log in separately to each system. Understanding trust relationships is therefore important in managing access control and for network security. For professionals responsible for IT infrastructure, learning about trust relationships and access control is a must.
Understanding Trust Relationships
Simply put, a trust relationship is an agreement between two systems that allows them to share resources and data with each other. The two systems are generally known as the "trusting" system and the "trusted" system. The trusting system accepts that the trusted system is authorized and has the right to access the resources in the trusting system. This allows seamless sharing of data between the two systems without requiring the users to enter credentials every time they want to access the other system. The trusted system itself may also provide access to other resources and systems, thereby facilitating a network of trust relationships among systems in an enterprise.
