Figure 6 shows an overview of the internal architecture of the gateway system. Whilst the internal processing of the gateway is complex, the end user sees only a single simple login screen before being connected to their familiar intranet services.
The powerful and concise policy system, combined with integration with existing standards based authentication and authorisation systems (using RADIUS and LDAP), means that once configured, there is minimal additional administration overhead involved. No user accounts are manually created or managed in the system, and no routine administration is required for gateway operation.
