  7. Benefits • Increased availability, capacity • Seamless disaster recovery • Flexible security options

  8. What’s new in Exchange Server 2010? • Elevation of Client Access Server (CAS) role • All client connections, regardless of protocol, are with CAS servers • CAS servers rely on ADC for high-availability CAS is critical

  9. Exchange 2010 Architecture Enterprise Network Phone system (PBX or VoIP) Hub Transport Routing and policy Edge Transport Routing and AV/AS External SMTPservers Unified Messaging Voice mail and voice access Mailbox Storage of mailbox items Mobile phone Client Access Client connectivity Web services Web browser Outlook (remote user) Line of business application Outlook (local user)

  10. What’s new in Exchange Server 2010? ADC for highest availability • Elevation of Client Access Server (CAS) role • All client connections, regardless of protocol, are with CAS servers • CAS servers rely on ADC for high-availability CAS is critical • Microsoft recommends hardware load balancing for every Exchange 2010 deployment • ADC recommended over NLB • Includes multi-role Exchange server installations • Includes installations with Microsoft clustering services

  11. The F5 Solution for Exchange Server 2010 • Prevent these pains • Dropped sessions  re-authentication, reconnection • Failed network connections  retries, delay • Slow response  trapped users • These capabilities • Health monitoring and intelligent load-balancing • Client persistence • Server off-load • Availability of servers, arrays and sites

  12. NLB and Hardware-Based Load Balancing… Which way to go?... For Exchange 2010, the choice is clear… Microsoft internal Exchange design: http://technet.microsoft.com/en-us/library/ff829232.aspx TechNet guidance for high-availability: http://technet.microsoft.com/en-us/library/ff625247.aspx

  13. The F5 Solution for Exchange Server 2010 • User - Client to CAS server • Mail - Mail flow through Edge Farms

  14. Availability • Health monitoring • Port/protocol requests • Real-time in memory connection tables • Intelligent load-balancing • BIG-IP always knows the most available server • Least connection method • See application template • Cross site availability • Site level health • Prioritized decision tree

  15. Persistence • Also known as affinity, or sticky sessions, persistence can help enhance a user’s application experience • Different types of persistence: • Source IP • Cookie • SSL ID • Each Exchange client connection type has a recommended persistence method

  16. Configuring persistence profiles in BIG-IP LocalTrafficProfilesPersistenceCreate Source IP and SSL ID Cookie

  17. Performance - SSL termination • Reduce cost and overhead of managing certificates by moving them to BIG-IP • BIG-IP is designed with dedicated chipset for encryption/decryption calculations • Increase Exchange server CPU utilization and network connections per second

  18. Security • Bi-directional proxy • Secure remote access • Pre-authentication • Application layer security for web clients • SPAM filtering

  19. Introduction:Exchange ActiveSync • ActiveSync protocolis used between smartphones and Microsoft Exchange for synchronizationof Mail, Callendar and Contacts • Username and Password are normally used for security. • One Time Password (OTP) or token is not used because it is not user friendly. • Client SSL certificate causing managment issue when trying to manage client certificate on 100s of different devices. • Using BIG-IP Access Policy Manager (APM) can be used to improve security for ActiveSync solutions.

  20. Exchange marked share • More than 200 Million installed Exchange mailboxes • http://download.microsoft.com/download/E/8/A/E8A154BF-CC35-4340-BD26-6265CDB06B6E/ExStats.doc • BIG-IP LTM and APM is a flexible tool and can be configured to improve security for ActiveSync users.

  21. ActiveSync, Microsoft Solution • Microsoft Solution • Authenticate user before client accessing Exchange server • Exchange 2007/2010 can verify deviceid • AD group check and basic url filter can be implemented on TMG DMZ Data Center MS Exchange MS TMG or ISA AD

  22. ActiveSync, F5 BIG-IP LTM & APM Solution DMZ Data Center • SSL Offload • Verify and enable access based on • User /password, AD group membership • IP location, Deviceid , Devicestype , Useragent • Brute force detection • ActiveSync commands used • URI (allow acces request to /Microsoft-Server-Activesync) • User home server MS Exchange AD

  23. BIG-IP example of security options that can be enabled for ActiveSync • SSL Offload • URI Check (/Microsoft-Server-ActiveSync and /autodiscover) • Agent Whitelist, Only Allow access from known devices type (based on agent information). Agent information also contains information about software version on phone. • Verify source IP address and enable access from known mobile carrier • Deviceid verification, Verify user AD attribute with information about provisioned Device id. • Login Bruteforce detection, Disable source IP address for 90 second after 3 failed logon • AD Group membership, only Allow Access for users member of ActiveSync Group • Verify ActiveSync command sent from Smart Phone with white list of approved ActiveSync commands • For large installation, verify AD information and route request to user home server • Verify Username and Password

  24. Access Policy in Visual Policy Editor • Visual Policy Editor enableseasyconfigurationof Access Policies for ActiveSync, withoutscripting.

  25. Summaryof APM Benefits • Security for ActiveSync users can be improved using BIG-IP Access Policy Manager • Verification of ActiveSync URI and User-Agent • AD group membership verification • AD user Deviceid attribute compared with deviceid from mobile phone • Authentication of user after verification of URI, UserAgent, AD Group and AD Deviceid • Detect and blacklist bruteforce IP address • Verify ActiveSync commands from devices whith whitelist of approvedcommands • SSO for otherMicrosoft services such as SharePoint
