Security identity
A Security identity is an entity (that is, a user, group, virtual group, or granted identity) that can be used to define a permission on a secured item, so that only authenticated users who are allowed to access this item can see it in its original repository or query results. Security identities are defined in a security identity provider.
For more information on sources that index permissions and how Coveo handles these permissions, see Coveo management of security identities and item permissions.
