Q1) You have just been promoted to manager of computer security for large enterprise (XYZ Corporation). Your first project as the security manager is to evaluate the principal physical characteristics used for biometric user authentication, the concepts of enrollment, verification, identification, and accuracy, and write a paper for the CIO to explain these topics. You can also add some examples of current technologies and commercial solutions in the field to help illustrate your points. Remember, the CIO isn't a "techy" type, so you'll have to use your skills as a security manager to translate the technology into a description that a business leader can understand.
