COEN 351 Spring 2009
Syllabus Instructor Lecture Notes Homework Final Prep
Sample Final
Project

In order to avoid duplication of contents, COEN 351 will be a practical course, whereas COEN 350 (Network Security) will explore theoretical issues deeper. Both courses together should leave the student with good theoretical and practical knowledge to implement a secure e-commerce site. In order to be self-contained, COEN 351 and COEN 350 will share some Nevertheless, COEN 351 will be essentially self-contained, merely assuming that students have acquired some maturity as a programmer. If a student does not know PERL or PHP, they will learn a smattering of it. Students with practical experience are encouraged to develop a project on their own.

Students are invited to collaborate heavily on the practical part and to test each others systems. However, the homeworks and of course the final should be individual with the exception of more practical homework problems, were collaboration is encouraged and allowed, but needs to be indicated on the hand-in.

Text Books

Suggested:

Warwick Ford, Michael S. Baum: Secure Electronic Commerce, 2nd Edition, Prentice Hall (PTR), 2001.

This is a book that is showing its age, but it is the only good introduction to some of the legal issues that we need to cover.

Gunther Birznieks, Scott Guelich, Shishir Gundavaram: CGI Programming with Perl (Paperback). O'Reilly, 2nd Edition

or one of the many good PHP books from O'Reilly. (I have at least four.)

Further Suggestions:

A CGI book

Either a Java security book or a .Net cryptography book

 

Helpful Reading:

Books on a scripting language such as Perl, PHP, ...

Dynamic weblanguage such as ASP.

Stuart McClure, Saumil Shah, Shreeraj Shah: Web Hacking, Addison Wesley, 2003.
