Join David Yahalom for an in-depth discussion in this video Separating object owners and access, part of Oracle Database 12c: Security.
Wrapping up our chapter on database users and privileges,…let's talk about one database schema design principle…that closely impacts your database security.…As we've learned in this chapter,…users and schemas in the oracle database…are identical; they are the same thing.…If you create a table, while connected…to the Oracle database as a specific database user,…then this table, which the user created,…will be owned by the user and reside in the user's schema.…
As such, that user will have full control over that table.…Let's imagine a CRM application…that contains a lot of tables…with sensitive information about your customers.…The CRM user will have full permissions…on all of the objects that it owns.…That is by design; you create tables inside a CRM schema…so the CRM user will be the owner of these objects.…Nothing surprising here; however, if your applications…will connect to the database using the CRM user,…then each application will essentially…have access to all tables, data, and code…that resides inside your CRM schema.…
Learn how to identify the major risks and security threats, and review general best practices for properly protecting and "hardening" any production database. Then, dive into hands-on demos that show how to set up user accounts, the connection between users and schemas, database object and system permissions, and roles in a multitenant environment, as well as encrypt data, audit user actions, and access to sensitive information. Plus, find out how to enable data-at-rest security via the Oracle Transparent Data Encryption and backup encryption options.
