The Single Connect role-based management (user/device/policy) concept is based on realms. Individual creations are collected under a group and groups are connected to each other. Realms connect the groups together, so that users can connect to devices by using policies. The diagram below illustrates Single Connect's realm structure, which allows admins to manage specific users to authenticate on specific devices and authorize on specific policies.

Policies are applied to SSH/Telnet connections. RDP and SFTP connections do not require policies.
