A SAC system consist of SAC Servers, Clients and the Secure Access Modem (SAM). Figure 1-1 shows SAC components and the protected network equipment communicating over secure tunnels via the PN. SAC Servers SAC Servers consist of an Administration Web Server, a Database Server (with hard disk backup), and an Authentication Server. As shown in Figure 1-1, these dedicated servers communicate with each other over a private network, and are managed by the SAC system administrator only. SAC Client Desktop Software The Client software is installed on remote user PCs or laptops to initiate calls to the Secure Access Modem and Authentication Server. It sets up secure tunnels between those devices, and then onto the protected network equipment. Figure 1-2 shows SAC Server/Client relationships. Secure Access Modem The Secure Access Modem (SAM) protects managed network equipment connected via the PN from malicious or unauthorized tampering by remote users. Note This manual describes the installation and operation of the SAC Client only. For detailed information about the SAC Servers or the SAM, contact your SAC system administrator. REMOTE DIAL-IN USER (SAC Client Software) Each connection sets up a secure tunnel that passes encrypted data to authenticated users.

Introduction & Specifications Introduction to the SAC System Theory of Operation SAC System Connections The Secure Access Modem is connected to the SAC Servers via the PN. The Authentication Server is connected to the PN via a modem bank, allowing access to the server by multiple users. A second Authentication Server may be added to minimize delay and avoid downtime. Access & Authentication Access privileges to network equipment are determined by the system administrator via the SAC Administration Server, typically located at a service coordination center. The Administration Web Console software communicates with the SAC Database Server, where access data and remote user accounts are stored. Access data from the Database Server informs the Authentication Server which authorized users may access specific network equipment as intended by the system administrator. Remote User Validation In order for the remote user to establish a connection with the protected network equipment, the following actions must occur: 1. Remote users must make a request of the system administrator for access rights to particular network equipment. 2. The system administrator must enter remote user accounts and a valid Secure Access Modem (SAM) into the SAC Database. 3. The SAM must be capable of obtaining a valid cryptographic (private) key from the Authentication Server at reset, powerup, timeout, or at the end of a session. (If information in the SAC Database does not agree with information sent by the modem, the SAM will be denied a valid private key.) 4. The remote user's client software must contact the Authentication Server to verify the remote user s SAM ID and Password. The authenticated user receives a public key and SAM phone number to make a secure connection to the requested SAM and protected network equipment.

Introduction & Specifications Introduction to the SAC System SAC Client Interface Any person intending to access protected network equipment must first be registered by the SAC system administrator and then assigned authentication privileges for a remote login. Once the SAC Client software is properly installed and configured, it can be launched from the remote user s PC or laptop to connect with the SAC Authentication Server and a Secure Access Modem. A successful login will create a secure connection to the protected network equipment. Chapter 2, Installation & Configuration in this manual provides detailed instructions on installing and configuring the SAC Client software on your PC or laptop. Chapter 3, Operation in this manual describes how to access the protected network equipment via the SAC Client interface, and other user functions. Web Management The SAC Web Console is an interface used primarily by the system administrator to perform almost all configuration and management of the SAC system via a browser (e.g., Internet Explorer). When the system administrator registers a user for remote login privileges, the user also receives limited access to two convenient Web Console functions: User Key Downloading and the User Profile. Your system administrator may choose to assign you additional super user privileges that allow you to control and manage either the SAC Servers, SAMs, or Users via the Web Console. The extent of these additional privileges are determined by which role you are assigned by the administrator. There are four roles in the SAC system, each activating specific links at the Web Console menu: Remote Login SAM Management Server Management User Management Table 1-1 and the accompanying screen illustrate the Web Console with the complete SAC Main Menu as seen by a super user who has permission to all menu functions. Function links on the menu will be displayed or hidden according the role(s) assigned. If you think you need additional permissions at the Web Console, contact your system administrator.

Chapter 2: Installation & Configuration Client Installation The Secure Access Client Software is typically installed by the remote user on a Windows XP or Windows 2000 PC/laptop equipped with an internal or external modem and a web browser (e.g., Internet Explorer). Note Refer to the Secure Access Controller Server/Client Release Notes for this version and check the minimum requirements and recommendations for your PC/laptop. Before Your Begin To properly install the SAC Client software as described in this chapter, the following conditions must be met: The system administrator must have registered the user in the SAC system with a User ID and Password, and enabled the user with the appropriate role(s). A valid Remote User Public Key (User.key) must be provided by the system administrator, or acquired by the user via downloaded at the Web Console (see Chapter 3, Operation ). The Secure Access Modem name (SAM ID) and the Authentication Server phone number(s) must be provided by the system administrator. If a previous installation of the Client is already resident, the Install Wizard will detect it and present a different sequence of instructions that allow you to keep or discard your configuration and user key. Proceed to the instructions for either of the following: First-time Client Installation Client Re-install or Upgrade To avoid conflicts with previously installed Client drivers, always restart Windows as prompted in the install or uninstall procedures. Special Considerations for Windows XP Media Center Edition 2005 When the SAC Client software is installed on a PC that is running Windows XP Media Center Edition 2005, the telephony service settings intended for Caller/ID will use the same communications (COM) port that is assigned to the modem. This conflict will lock up the COM port on the PC so that the SAC Client can not open the port. To resolve this conflict, disable all the telephony services in Windows XP Media Center Edition 2005 as follows: 1. From the Start Menu, click Settings, and then select Messenger and Caller ID. (In some cases, you will only be able to select Messenger.) 2. Under Show notification for:, select None. 3.
