As colleges and universities rely more heavily on software as a service (SaaS), they're putting more critical data in the cloud. What are the security issues, and how are cloud providers responding? "Campus Technology" ("CT") went to three higher ed SaaS vendors--Google, IBM, and TopSchool--and asked them to share their thoughts about the state of security in cloud computing. The panelists for this virtual roundtable discussion were: (1) Anthony Hill, CTO for SaaS-based student lifecycle management provider TopSchool. Previously he was CIO of Golden Gate University (California), where he led a major initiative to move the university's IT services to the cloud; (2) Jeff Keltner, business development manager at Google, responsible for Google Apps in the education sector worldwide; and (3) Dennis Quan, director of autonomic computing in the IBM Software Group. He launched the IBM/Google Cloud Computing partnership in 2007.
