I was wondering if the Database Firewall had a plugin framework to retrieve information from external systems when evaluating policies. I might want to use an attribute from LDAP or a score from an external risk engine to modify the SQL statement before it goes to the database.
I work in the Security Team which is starting to more fully support this product. I'm pretty sure the answer to any type of 3rd party API into DBFW is not supported at this time. The future of DBFW will probably intail further integration with other seeded Oracle products and then may have some of these types of features but not at this time.
