Computing

Motivation

Why secure and dependable computing is important?*
 Increased reliance on software to optimize everything from
business processes to engine fuel economy
 Relentlessly growing scale and complexity of systems and
systems-of-systems
 Near-universal reliance on a commodity technology base that is not
specifically designed for dependability
 Growing stress on legacy architectures (both hardware and
software) due to ever-increasing performance demands
 Worldwide interconnectivity of systems
 Continual threats of malicious attacks on critical systems
*Taken from “A high dependability computing consortium”, James H. Morris, CMU,
http://www.cs.cmu.edu/%7Ejhm/hdcc.htm

More Motivation


The cost of poor software is very high
 Annual cost to US economy of poor quality software: $60B
 source: US NIST Report 7007.011, May 2002.
Industry needs greater dependability and security
 Improved quality of products
 Improved quality of development processes
 Better system and network security, to avoid:



viruses, trojans, denial of service, ...
network penetration, loss of confidential data, ...
Improved customer satisfaction

Course Objectives



Have solid understanding of the basic concepts and
theory of secure and dependable computing
Getting familiar with some basic building blocks
(tools and APIs) needed to build secure and
dependable systems
No attempt to be comprehensive: topics covered are
what I am interested in and what I think important

Including project implementation and report
You can quote a sentence or two, but put those in quote
and give reference
You can build your projects on top of open source libraries,
but again, you should explicitly give acknowledgement and
state clearly which parts are implemented by you

Consequences for Cheating




You get 0 credit for the project/lab/exam that you
have cheated
If the task is worth 25% or more of the course, it is
considered a major infraction
Otherwise, it is considered a minor infraction
For major infraction and repeated minor infractions



You will get an F grade, and
You may be suspended or repulsed from CSU
