PRESENTATION:
"System & Software Reliability"
PRESENTATION BY:
Paul Stachour
ABOUT THE PRESENTATION:
Today, the reliability of the systems that we build is dependent to a large extent on the software which implements the vast majority of the functionality of the system. Most of the systems we build are not very reliable, using the following definition: “Reliability is an attribute of any computer-related component (software, or hardware, or a network, for example) that consistently performs according to its specifications.”
A component can fail to perform according to its specification for a variety of reasons. Paul believes that three of the important reasons are:
- IAA: Failure to provide Identification, Authentication, and Authorization of each entity in a system
- Compartmentalization: Failure to provide proper separation between parts
- Type-Safe Languages: Failure to ensure that data can never be out-of-range
Paul had the good fortune to work on Multics, an operating system built by MIT, GFE, & AT&T. Multics was in general use for about 20 years. It achieved a B2 security rating, hardly ever had to be restarted, and never lost any data (or had any stolen) on any project that he is familiar with. Multics was reliable because it was designed with the 3 above principles (& more) in mind.
Today Paul will walk us through a document that describes how the compartmentalization of Multics was accomplished, supplementing that document with his experience as a builder of software systems on Multics. Think about the compartmentalization (or lack thereof) on systems that you build or use.
ABOUT THE PRESENTER:
Paul received a B.S. in Mathematics, Secondary Education, and Chemistry at Iowa State University, Ames, Iowa and a M.S. in Computer Science at Ohio State University, Columbus, Ohio. He also received a Ph. D. in Computer Science at University of Waterloo, Waterloo, Ontario.
Paul is a Software Engineer specializing in total life-cycle Software Quality Assurance. He has extensive expertise in finding large numbers of different kinds of important defects in software. Paul has additional expertise in creating processes to build, document, and track requirements, designs, code, tests, approvals, and software issues. He is adept at creating correct, reliable, functional software in effective and efficient ways in many programming languages.
Paul has worked for many companies during his career including: Lockheed-Martin, Net Perceptions Recommendation Products, Delphax High-Volume Printers, Detector Electronics and H&R Block, as well as a contractor at various medical device companies.
Paul also has many years of teaching experiences from secondary schools to several universities. He also teaches partnership dancing.
