Security Information

TeleWeb utilizes the latest computer and security technology to ensure that all customer account information remains secure and accurate. The two components of TeleWeb, TelePC Server which resides on a TeleBank system, and the TeleWeb Server Network which resides in a secure location at AudioTel Corporation Headquarters, both implement strict security controls.

Account Access Controls

TeleBank maintains controls for the way in which each customer may access accounts. These controls are maintained through settings on the host software, downloaded to TeleBank, and within the TeleBank interface. Restrictions may be placed on account access and transfer rights. TeleWeb adheres to these restrictions on the TeleWeb Server Network and then verifies them on TelePC Server.

Password Protection

A customer is only allowed to access account information on TeleWeb with a valid login consisting of a customer number and PIN. Only customers who have been enabled for TeleWeb will be allowed access and only data for these customers will be transferred to the TeleWeb Server Network. After three simultaneous invalid PIN entries for a customer, access will be disabled for the customer preventing unauthorized access by a third party. Once disabled, only bank personnel may re-enable access through the TeleBank interface.

Secure Communication

All communication between the customer and the TeleWeb Server Network are conducted using the Secure Socket Layer (SSL) protocol. SSL provides data encryption, server authentication, and message integrity for the entire banking session. This assures that somebody will not be able to eavesdrop on the session, that the customer is connected with the TeleWeb Server Network and not an imposter, and that all information received will be accurate. Additional information on SSL may be found at http://docs.iplanet.com/docs/manuals/security/sslin/index.htm.

Account information is transferred from TelePC Server to the TeleWeb Server Network via the TelePC Virtual Private Network (TelePCnet). TelePCnet is a secure private communication channel established over the public Internet. All data transmitted on TelePCnet is encrypted using keys known only to TelePC Server and the TeleWeb Server Network. A large private key is used to establish this secure connection. Once this private key has been exchanged, a 128-bit session key is generated and used only for the remainder of the current session. After a secure TelePCnet connection has been established, the TeleWeb Server Network authenticates TelePC Server with a unique Bank ID. These methods insure that all conversations are private between known parties and may not be intercepted or repeated.

TelePCnet utilizes the Blowfish Encryption Algorithm to encrypt all communications. Details on the Blowfish Encryption Algorithm may be found at http://www.counterpane.com/blowfish.html.

Network Security

The TeleWeb Server Network is comprised of several components including a Firewall, Screening Router, Proxy Server, Web Server, and Database Server. The Firewall and Screening Router work in tandem ensuring that only authorized request are allowed to reach the Web Server. Any suspicious activity will result in access being denied and is logged for later review. The Proxy Server acts as an intermediary between the Web Server and the Internet. All requests are passed to the Web Server on behalf of the client and back to the client on behalf of the Web Server. This ensures that access directly to the Web Server is not possible significantly reducing the possibility of unauthorized access. The Database Server, where all account information is stored, is only accessible through request made by the Web Server. Access to account information is only allowed through the Web Server Banking interface.
