SUBJECT: database security Textbook required: Required Textbook(s): Title: Database Security Author(s): Alfred Basta, Melissa Zgola Publisher: Cengage Learning Edition: 1st Year Published: 2012 ISBN-10: 1435453905 ISBN-13: 9781435453906 Part 1 Identify and explain the default logins or user accounts for one of the database vendors discussed in the chapter. Part 2. Case Project 6-1: Database Password Policies, page 199 Create and document a written password policy to be given out to database users in an organization. Part 3. A database user (or role) is a user (or role) to which the system administrator can assign database privileges. An application user (or role) is a user (or role) created and recognized by an application and cannot be directly assigned database roles or privileges. In multi-tier environments, an authenticated application user must eventually be mapped to a database user or to a database role in order to access database objects. Read "Considerations for Using Application-Based Security" and discuss how a database user can be mapped to application user(s)/role(s). You can describe the consequences on the security of the whole system, its flexibility and performance (using connection pools).
