b.Service ConsumersThe ITWS Information Service is consumed by two types of subscribers: those subscribers internal to the NAS and those subscribers that are external to the NAS. c.Service FunctionalityThe XML Schema Definition (XSD) for the data outlined in this document is detailed in Appendix A:
d.SecurityThe ITWS Information Service is deployed in the “untrusted” region, providing access to both NAS and Non-NAS users, and is fully dependent upon NEMS for access control to verify the identity of the users, to grant the rights and permissions to access system resources, and other processes by which access to system resources is regulated according to a security policy. That is, this service employs none of the JMS security mechanisms described in Table . The ITWS Information Service only employs security control through the use of JMS header properties, as described in Section 5.b.1. All the security mechanisms below are provided by NEMS. The NEMS security capability provides authentication and service level access control including integrity, privacy, and encryption. Access controls are supported through the use of username and password credentials supplied when establishing connections to NEMS interfaces. Username and password credentials are unique to each NEMS client and established during on-ramping. Transport level encryption of messages between NEMS and Providers and Consumers is to be supported using Secure Socket Layer (SSL) and X.509 self-signed certificates established during the on-ramping process. Message bodies are validated against published service interface descriptions XSDs published on the NAS Registry/Repository (NSRR). Table : JMS Security Mechanisms
