  1. DeployingCitrix Secure Gateway A Workforce Mobility Solution

  2. Agenda • What is Citrix Secure Gateway? • Components and Requirements • Implementation • Think about this • Better Management and Usability with Feature Release 2

  3. What isCitrix Secure Gateway? Secure Internet Access

  4. What is Citrix Secure Gateway? • Secure Remote Access Product • Designed for use with MetaFrame only • Single IP access from the Internet • SSL Encryption • Communication over port 443 • Single Point Certificate Management

  5. Components of CSG Solution • Citrix Secure Gateway Server • Citrix NFuse 1.6 • Secure Ticketing Authority • Citrix MetaFrame XP, Feature Release 1

  6. Workforce Mobility Components and Requirements A Secure Clientless Internet Access Solution

  7. Solution Components • Citrix Secure Gateway Server • NFuse 1.6 or later with Citrix Secure Gateway Components • Hardware Load Balancer • Verisign or other Authorized Certificate • ACE/RSA Secure ID Server • NT Domain/Active Directory/Novell NDS • Secure Ticketing Authority Server

  8. Function of Citrix Secure Gateway • Encrypt ICA Traffic • Access Authorization (w/ STA) • Provide Connectivity • Provide Single IP connectivity to internet

  9. Function of NFuse Web Server • Provide Authentication Page • Provide Application List from MetaFrame • Authenticate user against ACE/RSA Server • Accept NT/ADS/Novell Credentials • Provide ICA Clients for download and install • This includes Active-X Control, Netscape Plugin, Java Applet

  10. Function of Load Balancer • Provide Fail-over capabilities to Citrix Secure Gateway and NFuse Servers • 2 – Citrix Secure Gateway Servers • 2 – NFuse 1.6 Servers • Provide Stateful Load Balancing for Solution

  11. Function of Certificates, Tickets, Login Verisign or other CA Certificate • Encryption Level Verification NT Domain/Microsoft ADS/ Novell NDS • MetaFrame Application Authentication ACE/RSA Secure ID • Provide Secure Authentication to Web Server Secure Ticketing Authority • Machine Level Verification/Authentication

  12. Workforce Mobility Implementation A Secure Clientless Internet Access Solution

  13. Server Specifications Citrix Secure Gateway • P700 Mhz with 1GB RAM • Citrix Uses P933 with 1GB RAM NFuse 1.6 Web Server • Standard Web Server w/ IIS 5.0 or above • Citrix Uses Dual P700 w/ 1GB RAM

  14. Authentication Considerations STA • Should NOT be located in DMZ • If compromised, can allow access to network • Should not be installed on Web Server ACE/RSA • Should NOT be installed on PDC • Does not require LDAP link to ADS/NDS • Usernames in RSA should match NT/ADS/NDS

  15. Architectural Considerations • Java Client or 986 Win32 ICA Client Required • Install Java Client on Web Server for Java Applet access • RSA is used to Secure Web Server Access • Logon to web server • Gain access to NFuse Application Set • NT/ADS/NDS is used for • User Authentication for Application List from MetaFrame • User Authentication to MetaFrame Connection • STA used for machine level authentication • Used to prevent man in the middle attacks • Verify that user on machine has already be identified

  16. Communications Ports Firewall (External to ICA Client) • NFuse 1.6 – 443 • Citrix Secure Gateway – 443 Firewall (Internal to Secure Network) • NFuse 1.6 to ACE/RSA Secure ID - 5500 • NFuse 1.6 Server to MetaFrame – 80 • NFuse 1.6 to STA – 80 • Citrix Secure Gateway to STA – 80 • Citrix Secure Gateway to MetaFrame – 1494

  17. Communication – Application Set Citrix Secure Gateway MetaFrame Server Farm and NT PDC ICA Client STA Firewall DMZ Interface NFuse Server ACE/RSA

  18. Communication – ICA File Creation Citrix Secure Gateway MetaFrame Server Farm and NT PDC ICA Client STA Firewall DMZ Interface NFuse Server ACE/RSA

  19. Communication – Connection Citrix Secure Gateway MetaFrame Server Farm and NT PDC ICA Client STA Firewall DMZ Interface NFuse Server ACE/RSA

  20. Creating the Login Web Page • Modify the ACE/RSA login page • Add NFuse Login Components • NT Username, Password • May want to configure Domain as static • Some ICA Connection Properties • Need to be configured before logon • Cannot be stored in a Cookie because of this • May be saved in directory on server but not secure

  21. Configuring the Java Applet • Run setup.class on your web server • Create HTML page for ICA session • Note: Optimal config is Ultra Thin Web Client • For Internet Explorer users, the HTML page could look like this: <applet code=com.citrix.JICA width=640 height=480> <param name=cabinets value=JICA-coreM.cab> <param name=address value=CitrixServer> • For Netscape Navigator users, the HTML page could look like this: <applet code=com.citrix.JICA archive=JICA-coreN.jar width=640 height=480> <param name=address value=CitrixServer> Ref: Citrix ICA Java Client Administrators Guide • See Installing the Citrix ICA Java Client; Chapter 2, Page 21 • See Creating an HTML Page to Launch the ICA Java Client; Chapter 3, Page 29

  22. Additional Steps (ACE/RSA Secure ID) • Install Net OS on Web Server • Create Entry for Web Server on ACE/RSA • Copy SDCONF.REC File to System32 on Web Server

  23. Demo Time A Secure Clientless Internet Access Solution

  24. Workforce MobilityThink About This A Secure Clientless Internet Access Solution

  25. NFuse ICA Clients • Install on NFuse Server for easy install Java Applet • Install on NFuse Server for Kiosk/Café Access • Universal Zero-Client Access SSL to ICA Client • HTTPS Web Site/Pages • Encrypt Browser Communications • Secure ID Credentials • NT Domain/ADS/NDS Credentials • Secure Ticket and ICA File

  26. Certificates CA Authority • Support by Microsoft OS by default • Flexible use for Kiosk/Internet Café Access Custom Certificates • Distribution/Management Challenges • Kiosk/Internet Café Access questionable • Highest Security

  27. MetaFrame XP,Feature Release 2 A Sneak Peak

  28. Features • Delegated Administration • Enhanced Web Administration • Enhanced Systems Monitoring and Analysis • User Collaboration • File Type Association • Smart Card Support • Client/Server Drag and Drop • Improved File Transfer/Client Drive Mapping • Client Customization Utilities • Installation and Deployment Enhancements • Hotfix Management

  29. Delegated Administration Create specialized administrators to handle specific areas of MetaFrame administration • Managing printers • Published applications • User policies • Task Based

  30. User Policies

  31. User Collaboration • One or many users may shadow a single user • Shadowing is not just for administrators any more.

  32. Content Redirection Published Acrobat Local Application(Outlook, Word, IE) SERVER CLIENT Acrobat content located anywhere

  33. Enhanced Systems Monitoring & Analysis • Summary Database • Monitor health of Database Connection Server • Schedule the transfer of daily data • Enable automated data purges • Specify server metric per server basis • Audit users to track user statistics, favorite applications, and server usage across the farm • Setup Cost Centers, Fee structures • Generate reports, all within the CMC • Bill by domain or cost centers • HTML report template • Pre-defined Crystal templates

  34. Enhanced Printing
