Security and Networks Track

Track description

The development of modern distributed computing and complex data management systems, such as exemplified by the GRID, relies increasingly on two components where specific advances are necessary to satisfy these stringent requirements. These two areas are Computer Security and Network Performance. This track addresses each of them, in the form of two series of lectures, and via a selection of topics at the forefront of the technology. The security part starts with background knowledge and move to specific technologies such as cryptography, authentication, and their use in the Grid context.
The Networking part focuses on two aspects that are of primary importance in a Grid context: TCP/IP enhancements and network monitoring. The aim is to present the fundamentals and the evolutions of the TCP/IP stack and to explore advanced Network measurement and analysis tools and services for end-to-end performance measurement and prediction.

Lecture description


Computer Security

Safe computing on the Internet requires understanding the techniques for reducing risk without sacrificing function. This series of lectures presents the background knowledge and discussion of the concepts and tools for protecting computing resources from misuse. Emphasis is placed on the role individuals play in improving the security of the whole community.

Robert D. Cowles, SLAC  +1(650)926-4965

With more than 30 years of experience in computing and as the Computer Security Officer at SLAC, the lecturer can ground the more abstract discussions with practical, real-world examples. In addition to seminars in the US and Europe, he has taught regular classes on Internet and web security for the University of California and Hong Kong University.  Education: BS Physics from University of Kansas, 1969; MS Computer Science from Cornell University, 1971.

High performance Grid Networking

These lectures present the fundamentals of the TCP/IP stack and the limits of the protocols to meet the  network requirements of the Grid application and middleware. The evolution of the network layer and of the transport layer are examine in order to understand the tendencies in the  high performance networking. Emphasis is placed on the practices that permit end to end performance measurement and improvement.
