Balancing Performance, Security and Usability in a Real-World High Performance Network

Time 09/29/04 08:45AM-10:00AM

Session Abstract

When managing a high performance networking environment, factors such as performance, security, and usability often come into conflict. Cumbersome access control measures may be needed for security, but negatively affect usability. Performance needs may drive use of less security than ideal. We will address the tradeoffs and ordering between these three elements based on experience within the PNNL high performance networking arena, exhibiting workable methods for establishing and meeting goals in all three areas. Our results will be illustrated via both our own experiences as well as a test network established for assisting in the decision-making process, as well as some of the protections that are currently in place. This includes a traditional layered defense methodology with specific elements selected based on our three criteria. It also includes novel s practical solutions such our distributed firewall model, which addesses a relatively lower cost to performance and usability while still maintaining an acceptable level of security. The PNNL high performance computing environment is driven by a science to solutions
approach, and incorporates a .25-teraflop prototype of a 9.1-teraflop Hewlett Packard
Linux-based supercomputer, as well as an IBM SP computer system with 512
processors and a theoretical peak performance of 247 gigaflops.
