  7. Distance Education Requirements Phase: Current business requirements - HUB billing integration for payment verification - Server upgrades - Expand - Expanded coverage of database to the entire university - Initiate study of streaming technologies

  8. Distance Education Requirements Phase, cont.: Future Requirements - Integration of course material within the campus Blackboardtm learning management system - Streaming Media incorporation within courses - Increase availability/access from a current student load of 150 students to a future load of 500 - Branding of On-line version of DE delivery - Search for software solutions for management and course delivery, either COTS or developed internally

  9. Distance Education Computer Security Policies - Current focus is Quality and Course Content No formal policy in place Blanket coverage provided by CMU master firewall only Areas of concern SSL encryption for web server Virus protection for both servers Maintenance software patches for OS’s Secure communications to the HUB for account status

  10. System State E-mail Communication ADMIN Server Windows NT Oracle Product Server Linux/Apache My SQL Virus Virus/Worm?

  11. Distance Education Observations: Adherence to current security policy is poor Administration server is currently out of commission due to virus or worm - Commitment to commercial mailing of courseware Administrative overhead and additional costs - Courseware development Current development time 6-12 months per course Course is developed by the instructor only Modular courseware should be considered for established courses

  12. Business Mission II How does this project fit the business mission? “My main concern is with delivery of content and quality to those who pay for the course.” Mel Rosso-Llopart Director, Distance Education

  13. Business Mission II We must ensure content delivery and quality by providing: • Confidentiality to DE students • Integrity of course materials • Availability of servers to deliver content * We need to make sure this system is survivable.
