Decision-Making in "Ethics and Computing" Scenarios
Participants in this workshop analyzed real case studies
representing some of the most difficult and controversial
topics that arise in the area of ethics and computing. Topics
considered included freedom of speech in cyberspace, constitutional
basis of freedom of speech in the U.S., right to privacy,
employee use of employer-owned computing resources, "cracker"
attacks such as the recent wave of "denial of service"
and security considerations, evaluation of safety-critical
software, and whistle-blowing and the role of the False
Claims Act in aiding whistleblowers. Case studies also covered
ethical decision-making in employee disciplinary actions,
the role of codes of ethics in guiding behavior. Analysis
of the case studies emphasized development of appropriate
critical thinking skills.
Dr. Kevin Bowyer is a faculty member in the Department of
Computer Science and Engineering of the University of South
Florida. Dr Bowyer, author of the book, Ethics and Computing
(second edition, IEEE Press, 2000), has conducted faculty
workshops on the theme of “Teaching Ethics and Computing,”
sponsored by the National Science Foundation. His publications
in this area have appeared in Computer Magazine and the
Journal of Information Systems Education. Dr. Bowyer was
a keynote speaker at the 1999 Information Systems Education
Conference (ISECON). Dr. Bowyer was elected as a Fellow
of the IEEE in 1997. He has served as EIC of the IEEE Transactions
on Pattern Analysis and Machine Intelligence, and as the
North American Editor of the Image and Vision Computing
Journal. He completed his PhD in Computer Science at Duke
University.

Assuring Secure Electronic Commerce for Your Enterprise
Making sure your vital information systems are secure is
critical, given the exploding interconnectivity and such
cyberspace dangers as hackers, script kiddies, and other
cyber miscreants. This short course covered the fundamentals
of information assurance and explored trends in hacking
and electronic commerce security.
Part one covered the foundations of information security
- how you can achieve your goals of confidentiality, integrity,
and availability while being protected by core enterprise
security services. Participants received a grounding in
cryptanalysis, and such encryption schemes as DES, Skipjack,
RSA, PGP and AES. Participants also learned the fundamentals
of operating systems and database systems security, including
access control models and enforcement mechanisms supporting
security architectures. Attention was paid to telecommunications
network security - in particular, the role of Internet convergence
in expanding the threat perimeters.
Part two, covered emerging electronic commerce trends and
their impact on enterprise security, prefaced with a practical
introduction to risk management. Explored were
Digital enterprise development platforms, Java 2 and
its security architecture, and the benefits and risks
of XML and Mobile Agents from the assurance perspective.
Intranet, Extranet, and VPN enterprise technologies.
Digital signatures, Internet voting, and electronic
contract technologies, including a detailed treatment
of Internet payment systems based on virtual pins and
E-Cash.
Design and deployment strategies for Public Key Infrastructures
(PKI) in large and federated enterprises, including coverage
of the X.509 standard for public key certificates.
Legal implications of information assurance and electronic
commerce assurance are discussed, including the potential
effects of longarm jurisdiction, Presidential Decision
Directive 63, the Digital Millennium Copyright Act, and
the Uniform Computer Information Transactions Act.
