Abstract

The inventive system includes a host, a network including a security gateway, and a public application. Established are an access session between the network and the host and an application session between the public application and the network. An application session record is created for the application session, and includes the user'"'"'s public user identity used to access the public application, the user'"'"'s private user identity used to access the network, a host identity, and an application session time. To determine the private user identity for the application session, the security gateway sends a query with the host identity and the application session time. These are compared with the host identity and access session time in an access session record. If they match, then the private user identity in the access session record is returned, and it is stored as the private user identity in the application session record.
