  1. Web Services Enhancements Webinar 2/23 & 2/26

  2. Agenda • AE Application Server/Service Enhancements • MS SQL Browser Application Security • Errors many vendors make • Controlling ESS Access via IIS

  3. AE Service Components • Service Components • AutoTask • Running reports, tasks, communications • Background Processes • Data processes • Timecard calculations • Communication Server • Real-Time data collection

  4. Existing Server Layout IIS Servers SQL Servers Application Server • AutoTask • Running reports, tasks, communications • Background Processes • Data processes • Timecard calculations • Communication Server • Real-Time data collection

  5. Distributed Processing AutoTask - Running reports, Tasks, Communications Background Processes - Data processes, Timecard calculations Communication Server- Real-Time data collection

  6. Enhanced Server Layout IIS Servers SQL Servers Application Servers AutoTask Server Background Processing Server Communication Server

  7. Advantages • Ultimate in scalability • Lower total cost of ownership • 100% redundancy = 24/7

  8. MS SQL Security • Microsoft Security Holes • Browser app written in .asp • Default.ASP page • Contains authentication – Connectivity Information • ASP is not encrypted • Low Isolation NOTE: ASP can utilize obfuscated secrets

  9. ASP Pages

  10. What is Low Isolation? MS SQL Server ISAPI, DLL’s & ADO High ASP Pages Medium IIS Service / Process Low Web Server

  11. Advantages of High Isolation • If Server fails, service isn’t affected • If Service (AeWebLoader) fails, Server doesn’t shutdown • Further removed from IIS process = more security Note: High Isolation does slow down service a little

  12. Controlling ESS Access Internet Information Services

  13. Directory Security

  14. Deny / Grant IP or PC

  15. Summary • Distributed Application Server • Ultimate in Scalability • Only supported in Enterprise Edition • Microsoft secure development strategy • ISAPI vs. ASP (typical) • Securing ESS accessibility
