EDI Services provides security features for Information Exchange and for network access to Information Exchange to help prevent unauthorized access to the mailbox service and customer data.

For AT&T Global Network Services users, network access is protected by account IDs, user IDs, and passwords.

For ANX users, the GXS connection to ANX is fully compliant with the security protocol prescribed by the Automotive Industry Action Group (AIAG).

For Internet users, employs standard Internet security protocols for authentication, data confidentiality, and data integrity.

In addition, once users have logged in to a network they must provide a current password to access the Information Exchange service. You can also select the Extended Security Option for additional password and mailbox security.

Through the Information Exchange user profiles that you define and maintain, you can specify what user IDs can send or receive messages and what part of the message transmission you are willing to pay for. Using the receive command, you can choose to accept messages only from certain account IDs, user IDs, or both. Information Exchange does not place unauthorized messages in a user's mailbox.

The security-enhanced environment for Information Exchange includes a unique user password to access the service, defined profiles, categorical or service limit facilities, and multiple levels for general users and service administrators.
