ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Virtualization technologies have the potential to transform the telemetry post-processing environment. Significant efficiencies can be gained by migrating telemetry post processing activities to virtual computing platforms. However, while facilitating better server utilization, virtualization also presents several challenges; one of the most difficult of those challenges being security. In virtualization, server environments are replicated in software; unfortunately, the security individual servers provide is not replicated in a software stack implementation of a server environment. After reviewing virtualization fundamentals, security issues and their impact on telemetry post processing will be discussed.
