Foil 38 Portal Building Blocks -- Security

From Case Studies in Internetics-- Introductory Material CPS714 Computational Science Information Track -- May 23 99. by Geoffrey C. Fox
So in this course, we will discuss security as it is a common service needed by many portals
  • It can be implemented simply as a user name / password but there are several special features
  • Encryption -- keeping information secret
  • Authentication -- identifying and authorizing individuals to access particular capabilities
  • Different technical approaches -- especially Kerberos and Public Key Infrastructure
And a discussion of special difficulties as seen by spate of stories about viruses, hackers and security leaks of computer information from government facilities
