This document discusses several recommendations and frameworks for improving security in Oracle Warehouse Builder (OWB). It recommends: 1) Registering source system locations and granting only limited access to registered source systems. 2) Using individual user accounts instead of a repository account to improve auditing. 3) Defining target-to-target permissions at the object level. It also describes security frameworks for freezing projects, implementing PL/SQL security checks, and controlling external runtime security.
