    • White paper Enabling mobile work while ensuring network security & data privacy Citrix GoToMyPC Corporate for secure remote access
    • Executive Summary Workplace mobility is on the rise as more organizations explore the advantages of enabling employees to work anytime, anywhere. If your company hasn’t adopted a mobile work strategy yet, the request from management is likely on its way. If, however, you already have a mobile or remote work program in place, you are well aware of the return on investment that mobility provides — from increased employee productivity and organizational agility to the ability to attract and retain top talent and much more. Of course, enabling mobility means that you have to provide employees with remote access to office computers, which naturally invites the question: Does remote access infringe on corporate security? This paper explores how Citrix® GoToMyPC® Corporate protects the integrity of the corporate network and the privacy of sensitive data by providing full spectrum security. As secure as online banking, GoToMyPC Corporate was created with government-grade data encryption and always ensures full user control. As secure as online banking, GoToMyPC Corporate was created with government- How it works grade data encryption and GoToMyPC Corporate enables secure browser-based access to any Internet-connected Windows PC. always ensures full user Keyboard, mouse and display updates are transmitted over a highly compressed, encrypted stream, control. yielding a “like being there” experience over broadband and impressive performance over dial-up. Applications supported by GoToMyPC Corporate include: • Screen Sharing: Launch a resizable Viewer from any browser to enable interactive access to any desktop application (even those that are not Web based). • File Transfer: Drag and drop files, folders and directories — including fileshares — between the host Viewer and local client computer. • Remote Printing: Print from the host Viewer to a local client printer. 2 Figure 1: GoToMyPC Corporate communication architecture.
    • GoToMyPC Corporate is a hosted service made up of four components: • Computer: A small footprint server is installed on the computer to be accessed. Typically, this is a home or office PC with always-on Internet access. This server registers and authenticates itself with Citrix Online’s GoToMyPC broker. • Browser: On the client side, the remote or mobile worker launches a Web browser, visits the secure GoToMyPC Web site, enters a username/password and clicks a “connect” button for the desired computer, sending an SSL-authenticated, encrypted request to the broker. • Broker: The broker is a matchmaker that listens for connection requests and maps them to registered computers. When a match occurs, the broker assigns the session to a communication server. Next, the client viewer — a tiny session-specific executable — is automatically loaded by the browser’s Java Virtual Machine. The GoToMyPC Viewer runs on any computer with a Java-enabled browser, including many wireless devices. • Communication Server: The communication server is an intermediate system that relays an opaque and highly compressed encrypted stream from client to server for the duration of each GoToMyPC Corporate session. “ Password Change Enforcement The security features of GoToMyPC Corporate are Host Security Settings head and shoulders above Failed Log-In Lockout other standalone remote- ” access products.

With GoToMyPC Corporate, remotely accessing traffic cannot be compromised. the corporate network – just like a bank account – should be a convenience that in no way compromises security. Strong Encryption Keys: Even a strong cipher is vulnerable if it does not use strong, confidential encryption keys. That’s why for Here’s how GoToMyPC Corporate safeguards network security each connection, GoToMyPC Corporate generates unique secret and data privacy: keys derived using a zero-knowledge, public-key-based protocol called SRP.

Additionally, host security features allow connections and unexpected client IP addresses. They also serve users to blank the host screen and lock the host keyboard and as audit trails, making it possible to see who accessed a particular mouse from accepting input.
