8 SSL VPN Overview Security Socket Layer (SSL) VPN is an emerging VPN technology. It uses SSL to provide certificate-based identity authentication, data encryption, and data integrity check for remote users to securely access the internal corporate network. H3C SecBlade SSL VPN greatly simplifies mobile user and network management by providing the following benefits: easy to use, zero configuration for users, no need to install and maintain the client, simple to deploy, high security, and fine grained security control. The H3C SecBlade series devices can function as ingress gateways for enterprises of any size as well as proxy gateways of internal server clusters for medium-sized and large enterprises. SSL VPN supports three access methods: Web access: Enables web users to access servers over HTTPS connections through the SSL VPN gateway. TCP access: Enables TCP-based applications to securely access open server ports. TCP-based applications include remote desktop web access, desktop sharing, Telnet, mail transfer, Notes, and general TCP service. IP access: Enables secure communications between user terminals and servers at the network layer so that all IP-based applications can securely communicate with other hosts. Using role-based right management, SSL VPN can restrict user access to resources according to user identity. In addition, it incorporates the user host security checking feature, implementing dynamic user access rights assignment. SSL VPN gateways support Web management. An administrator can configure and manage the SSL VPN system through a Web browser. H3C SecBlade SSL VPN defines three roles: Super administrator: Managers of the root domain, which is created automatically upon SSL VPN startup. A super administrator can create domains, initialize the administrator passwords of domains, and assign resource groups to domains. Domain administrator: Managers of common domains, which are created by super administrators. A domain administrator can create and delete local users, user groups, resources, resource groups, and security policies for the domain. SSL VPN user: Users accessing network resources through SSL VPN. An SSL VPN user must pass authentication on the SSL VPN gateway. After authentication, an SSL VPN user can access the SSL VPN gateway, and the SSL VPN system will assign the user access rights based on the security status of the user and the user group to which the user belongs. This document introduces the configuration and management tasks of super administrators. 1

9 SSL VPN Gateway Configuration Gateway Configuration Before logging into the SSL VPN Web management interface, you need to perform some simple configurations on the SSL VPN device: Task Connecting to the SSL VPN Device Enabling the Web server Enabling the SSL VPN service Remarks Use a console cable to connect the terminal for configuration with the console port of the SSL VPN card. To allow administrative access to the SSL VPN Web management interface, you must enable the Web server on the gateway. Enable SSL VPN service through the command line. Connecting to the SSL VPN Device Introduction to the console port Every H3C SecBlade SSL VPN card has an RS232 port, that is, the console port, through which you can configure the card. Introduction to the console cable The console cable is an 8-wire shielded cable with an RJ-45 connector at one end and a DB-9 receptacle at the other end, as shown in Figure 1. The RJ-45 connector is for connecting the console port of an SSL VPN card and the DB-9 receptacle is for connecting the serial port of a terminal for configuration. Figure 1 Console cable A X3 A Connecting the console cable Connect the console cable as follows: 1. Select a terminal for configuration. The terminal can be a character terminal with a standard RS232 port or a common PC. A PC is used in most cases. 2. Connect the cable. Making sure that the SSL VPN device and the terminal for configuration are powered off, connect one end of the console cable to the RS232 port of the terminal and the other end to the console port of the SSL VPN card. 2

10 Enabling Web Server and SSL VPN Services After you enable the Web server and SSL VPN service, the gateway will be able to provide default settings-based SSL VPN services. Enabling the Web server Follow these steps to enable the Web server: To do Use the command Remarks Enter system view system-view Enable the Web server web server enable Enabled by default Enabling the SSL VPN service Follow these steps to enable the SSL VPN service: To do Use the command Remarks Enter system view system-view Enable SSL VPN service svpn service enable Enabled by default 3

11 Logging Into SSL VPN Management Interface IMPORTANT: For security purposes, after you log in to the SSL VPN for the first time by using the default super administrator account, change the default password and save the new password properly. On a PC, launch the Web browser and enter the SSL VPN login address in the form of address of the Ethernet interface of the device/admin to log into the SSL VPN management interface. The management port number defaults to 444. It is recommended that you use IE 6.0, Firefox 1.5, Netscape 8.0 or above, and set the screen resolution to NOTE: If the device operates in SSL Offload Mode and then restarts, you need to enter the address address of the Ethernet interface of the device:management port (444 by default)/admin to log into the device. For information about the SSL Offload Mode, see the Work Mode in Device Management. After the SSL VPN service is enabled, the system automatically creates a domain named root and create a default super administrator account, whose username and password are both administrator. To log into the SSL VPN gateway, enter the default username and password, Click Option and select to log in to the root domain, and click Login, as shown in Figure 2. If you select the check box before Save current user name, the input username is saved and you can select it from the Username dropdown list at the next login. To switch to the interface in simplified Chinese, click the language link at the top right corner. When you log in to an SSL VPN on the same host, if the language of the interface has been switched, you must clear the cache of the browser. Otherwise, English and Chinese will appear on the pages at the same time. Figure 2 SSL VPN login page 4

12 NOTE: The root domain is the default domain of the system. All users in the root domain are super administrators, whose responsibilities include managing devices, creating common domains, creating resources, and assigning resources to common domains. 5

13 Introduction to the SSL VPN Management Platform The SSL VPN management platform is very friendly. It allows you to perform SSL VPN configuration and management easily and quickly, as shown in Figure 3. Figure 3 SSL VPN management interface (1) Information column (2) Configuration area (3) Navigation tree Information column: Displays administrator login information. The logo picture and page title can be customized by the administrator. You can click Help to view information about SSL VPN overview, functions, and scope, or click Exit to return to the login page. Configuration area: Allows the administrator to view system information, and configure users, resources, and policies. Click the tabs to switch between tab pages. Navigation tree: Navigates you to different management functions. You can click a cross button to display sub-menus. 6

14 Device Management Overview Device management can provide you with the operation status of the SSL VPN system. Through device management, you can view real-time information such as the current system resource utilization and SSL connection status, and history information such as the start time and SSL connection statistics. Besides, you can configure an IP address for every physical Ethernet interface of the device, configure the log host for the device, save the system configuration of the device, and reboot the whole device.

22 SSL Offload Server Overview SSL offload means that plug-in cards provide SSL encryption and decryption services for the internal Web server and provide externally SSL encrypted access to the Web server through HTTPS, while the internal Web server only processes services but performs no SSL encryption calculation, which consumes lots of CPU resources. This improves the Web server's processing ability. Configuration Tasks Select SSL Offload from the navigation tree to enter the SSL offload policy configuration page, as shown in Figure 14.
