Description
Security in a relational database management system is complex, and too few DBAs, system administrators, managers, and developers understand how Oracle implements system and database security. This book gives you the guidance you need to protect your databases. Oracle security has many facets: Establishing an organization's security policy and plan Protecting system files and passwords Controlling access to database objects (tables, views, rows, columns, etc.) Building appropriate user profiles, roles, and privileges Monitoring system access via audit trails Developing appropriate backup and recovery strategies Oracle Security describes how these basic database security features are implemented and provides many practical strategies for securing Oracle systems and databases. It explains how to use the Oracle Enterprise Manager and Oracle Security Server to enhance your site's security, and it touches on such advanced security features as encryption, Trusted Oracle, and various Internet and World Wide Web protection strategies.

She has presented papers at numerous conferences throughout the world, including various IOUG-A, DECUS, EOUG, and Oracle OpenWorld conferences. At the 1997 East Coast Oracle conference, Marlene tied for first place with Steven Feuerstein, receiving an "Outstanding Speaker" award. She also received the "Distinguished Speaker" award two years in a row at ECO-'95 and ECO-'96. Marlene's articles have appeared in Pinnacle Press' Oracle Developer magazine, IOUG-A's SELECT magazine, and many user group publications.

After doing application development in FORTRAN and what then passed for "Forms," he began to specialize in DBA work. In the ensuing years he has worked for a wide variety of customers, many of whom wanted some form of access control implemented in the database. Some of the techniques acquired during these experiences are reflected in this book. Computer programming was not Bill's original occupation. His first bachelor's degree is in music education. It was while serving in the U.S. Navy that he became interested in electronics and, later on, computers. For relaxation, Bill likes to spend time outdoors with Ellen, his wife, enjoying their mutual interests of camping, biking, and skiing.
