21 SSL VPN A Virtual Private Network (VPN) is a network that uses public telecommunication infrastructure, such as the Internet, to provide remote offices or traveling users with access to a central organizational network. A secure tunnel is formed across the public network which carries private network traffic between distant offices. This traffic is usually encrypted and compressed for enhanced performance and security. VPN technology has replaced the need to acquire and maintain expensive dedicated leased-line telecommunication circuits once typical in wide-area network installations. A VPN user can access the central network in a manner that is identical to being connected directly to the central network. Hence, it is ideal for business telecommuters or employees working from home. It is essential that the connection between the central network and remote location meets certain requirements like: Flexible Access: The remote users must be able to access the organization s network from various locations, like Internet cafes, hotels, airports etc. The range of applications available must include web applications, mail, file shares, and other more specialized applications required to meet corporate needs. Secure connectivity: Guaranteed by the combination of authentication, confidentiality and data integrity for every connection. Usability: Installation must be easy. No configuration should be required as a result of network modification at the remote user end. The given solution should be seamless for the connecting user. A SSL (Secure Socket Layer) VPN fulfills the above requirements by providing easy-to-use and secure access to remote users. It allows access to the corporate network and provides the ability to create point-to-point encrypted tunnels between remote user and the company s internal network. It requires a combination of SSL certificates and username/password for authentication to enable access to the internal resources. The Appliance extends its VPN feature to include SSL VPN functionality to provide secure access to a company s central network to remote users. It delivers a set of features and benefits which are easy to use and control and which allow access to the corporate network from anywhere, anytime. Depending upon requirement, remote users can access the central network through SSL VPN Client or End user Web Portal (clientless access). It offers a secure web portal which can be accessed by each authorized user to download a free SSL VPN Client, SSL certificates and a client configuration. In addition, it offers granular access policies, bookmarks to designated network resources and portal customization. Note SSL VPN is not supported when the Appliance is deployed as Bridge. SSL VPN feature is not available for Cyberoam CR15i models. Page 21 of 55

22 Concepts SSL VPN Access Modes The Appliance authenticates any remote user based on user name and password. A successful login determines the access rights of remote users according to user, group and the SSL VPN policy. The SSL VPN policy specifies whether the connection will operate in Tunnel Access Mode, Web Access Mode or Application Access Mode. Tunnel Access Mode Tunnel Access Mode provides remote users with access to the corporate network through laptops as well as from Internet cafes, hotels, airports etc. It requires an SSL VPN Client at the remote end. Hence, remote users are required to download and install SSL VPN Client from the SSL VPN Portal. The Client establishes an SSL VPN tunnel over an HTTPS link between the remote user and the Appliance to encrypt and send the traffic. Here the Appliance acts as a secure HTTPS gateway and authenticates remote users. The Appliance allows two types of tunneling: Split Tunnel: This ensures that only traffic for the private network is encrypted and tunneled while Internet traffic is sent through the usual unencrypted route. This is configured by default and is used to avoid bandwidth choking. Full Tunnel: This ensures that not only the private network traffic but other Internet traffic is also tunneled and encrypted. Web Access Mode Web Access Mode is used when remote users want to access SSL VPN using a web browser only, also termed as clientless access. It provides users with access to certain Enterprise Web Applications/Servers. This feature comprises of an SSL daemon running on the Appliance unit and an SSL VPN Portal which provides users with access to network resources behind the Appliance and certain web applications as configured in the SSL VPN policy. Application Access Mode The Application Access Mode also provides clientless access. It gives the user access to web applications as well as certain enterprise applications through a web browser. The feature comprises of an SSL daemon running on the Appliance unit and an SSL VPN Portal which provides users with access to different TCP based applications like HTTP, HTTPS, RDP, TELNET, SSH and FTP without installing a client. In this mode, the Appliance acts as a secure gateway and authenticates the remote users. On successful authentication, the Appliance redirects the web browser to the web portal from where the remote users can access the applications behind the Appliance. Configuring Application Access mode is a two-step process: 1. Select the Application Access mode in SSL VPN policy 2. Assign the policy to the User or Group For Administrators, the Web Admin Console provides SSL VPN management. Administrator can configure SSL VPN users, access methods and policies, user bookmarks for network resources, and system and portal settings. Page 22 of 55

23 For remote users, the customizable End user Web Portal enables access to resources as per the configured SSL VPN policy. With no hassles of client installation, it can be termed as clientless access. Prerequisite The following requirements should be fulfilled for the remote user to access SSL VPN in Application Access Mode: OS should be Windows 2000, Windows XP, Windows 7, Windows Vista or Windows Server Remote user should have the Administrator privileges. Java Runtime Environment V 1.6 or above should be installed. Threat - Free Tunneling The Appliance scans the VPN Tunnel Traffic (incoming and outgoing) for malware, spam, inappropriate content and intrusion attempts, ensuring Threat-free Tunneling. Furthermore, VPN traffic is subjected to DoS inspection, although the Appliance does provide the option of bypassing DoS inspection for specific traffic. The Appliance does not have an exclusive port assigned for the VPN Zone like the LAN, WAN and DMZ ports. As soon as a VPN connection is established, the port/interface used by the connection is automatically added to the VPN zone, and on disconnection, the port is removed by itself. The VPN zone is used by both IPSec and SSL VPN traffic. Note Threat Free Tunneling is applicable only when the SSL VPN tunnel is established through Tunnel Access Mode. Network Resources Network Resources are the components that can be accessed using SSL VPN. It provides access to HTTP or HTTPS servers in the internal network, Internet, or any other network segment that can be reached by the Appliance. The Administrator can configure Web (HTTP), Secure Web (HTTPS), RDP, Telnet, SSH or FTP bookmarks and internal network resources to allow access to web-based resources and applications. If required, custom URL access can also be provided. Page 23 of 55

24 Network resources: Resource Bookmarks Bookmark Groups Custom URLs - Not defined as Bookmark Enterprise Private Network resources Accessible in Mode Web Access Mode, Application Access Mode Web Access Mode, Application Access Mode Web Access Mode Tunnel Access Mode Portal The Appliance s SSL VPN Portal is the entry point for any remote user to the corporate network. It provides easy access to network resources through a secure tunnel. It is possible to customize the portal interface by including the company logo and a customized message to be displayed to users when they log into the portal. The Portal displays only those network resources that are assigned to the logged in user through the SSL VPN Policy and Access Mode. Page 24 of 55

25 Cyberoam Configuration for SSL VPN Configuration of the Appliance for SSL VPN can be done from VPN > SSL.
