Using LDAP to solve one company's problem of uncontrolled user data and passwords
This case study will analyze a massive undertaking of centrally consolidating user data, and in particular passwords, from numerous sources. The effort goes way beyond just the securely capturing and storing of the data but it builds a framework whereupon the data can be successfully used by numerous disparate applications for authentication, authorization, access control, and overall data management. This project faced some hurdles which seem all too common in the IT industry today. The number of applications for the company had grown out of control due to legitimate business needs and with each application came the responsibility and burden of user data security and management in very different fashions.

Identity Protection and Smart Card Adoption in America
This paper will address smart card technology as a viable alternative to present financial and identity standards, and why it will be woven into the American identity fabric over the next decade. The perceived security value, the increased emphasis on positive identification of U.S. citizens and non-citizens alike, by the federal and state governments (as a result of the tragedies of 9/11/2001), and the new business value propositions, will become compelling reasons to adopt smart cards as a standard part of identity for many applications in the future.
