Applied Oracle Security: Developing Secure Database and Middleware Environments- P13:Computer security is a field of study that continues to undergo significant changes at an extremely fast pace. As a result of research combined with increases in computing capacity, computer security has reached what many consider to be “early adulthood.” From advances in encryption and encryption devices to identity management and enterprise auditing, the computer security field is as vast and complex as it is sophisticated and powerful | 94 Part II Oracle Database Vault racle has always endeavored to increase the capabilities of the Oracle Database. -W Over the years staggering innovations have been realized in performance I reliability extensibility and sheer capability. Oracle Database is the number one database in the world because of these unmatched capabilities. But as robust as Oracle Database is in the database security arena a few things about the implementation needed to be improved. It may be startling to discover that until recently a security gap in Oracle Database desperately needed to be filled. This gap has become wider and more relevant because of the critical security challenges we face with compliance and cyber security today. Oracle Database Vault fills that gap elegantly and innovatively with additional layers of security. And unlike many features of the database Oracle Database Vault radically changes what you do as a DBA and how you do it. Therefore you will most certainly want to review this part carefully In Chapters 4-7 you ll learn about Oracle Database Vault in detail. This chapter discusses the security gap including the reasons why Database Vault was created. Understanding the design intent can help you understand why you should use it when you should use it and how you should use it. That is the goal of this chapter To understand why Oracle Database Vault is needed and how its core components work the way they work. Chapter 5 is perhaps the literary equivalent of the military s basic training. This chapter leads you through the basic workings of the product including the core capabilities and principles that Oracle Database Vault brings to the database. Chapter 6 puts Oracle Database Vault to work in the context of application building. To appreciate the power of Oracle Database Vault and what it makes possible the applications used in the examples are somewhat unconstrained that is you have the flexibility to modify the application configuration and potentially the .
