Oracle Security Blog

Last week I posted a blog introducing SCAP and OVAL. Here is a quick follow-up with a link to a sql57_test example using the Oracle E-Business Suite - it will suffice for any Oracle database.

Last week’s unprecedented ransomware cyber attacks (http://preview.tinyurl.com/lhjfjgk) caught me working through some research on security automation. The cyber attacks evidently were attributed to an unpatched Windows XP vulnerability. When challenged with securing 1,000s of assets such as all the Windows desktops and Linux servers in an organization, automation quickly becomes a requirement.

The most recent version of the Oracle E-Business Suite, Release 12.2, introduces on-line patching to reduce downtime requirements. This new technical functionality is based on Edition-based redefinition provided by the Oracle 11gR2 database. For the E-Business Suite to make use of Editioning, Oracle has added a new schema to the ‘APPS’ family – the APPS_NE schema.

The APPS_NE schema is the owner of those objects previously owned by APPS that cannot be Editioned or in other words; the APPS_NEW is the APPS schema for the non-editioned database objects.  

This is the eleventh and final posting in a blog series summarizing the new Oracle E-Business Suite 12.2 Mobile and web services functionality and recommendations for securing them.

The evolution of the Oracle E-Business Suite since its inception in the late 1980s has gone through many significant changes. For example, I can personally remember in the late 1990s upgrading clients to release 10.5 of the E-Business Suite with the big change being the introduction of the APPS schema.

This is the tenth posting in a blog series summarizing the new Oracle E-Business Suite 12.2 Mobile and web services functionality and recommendations for securing them.

Oracle Corporation has been building out Mobile and Smartphone applications for the Oracle E-Business Suite for a number of releases. Before release 12.2.5, this functionality was designed only for deployment through a corporate VPN, not through an Oracle E-Business Suite external node over the Internet (e.g. a server in DMZ).

For those of you using and/or considering Unified Auditing, in case you might have missed, Oracle has made significant changes to Unified Auditing in 12.2. Unified Auditing, new in Oracle 12c, represents a complete rewrite of how native database auditing works - see the links below for Integrigy research on Unified Auditing.

This is the ninth posting in a blog series summarizing the new Oracle E-Business Suite 12.2 Mobile and web services functionality and recommendations for securing them.

The most common use of web services with the Oracle E-Business Suite is the Oracle Suppler Network (OSN). Do not confuse OSN with the Oracle Social Network (also referred to as OSN) or when configuring OSN, do not confuse the Oracle Transport Agent (OXTA) web services with Oracle Training Administration (OTA) web services.

After discussions at Collaborate2017 with several PeopleSoft architects we have revised our Guide to PeopleSoft Auditing. The key change is the recommendation NOT to use PeopleSoft’s native database auditing and to instead use Oracle Fine Grained Auditing (FGA). FGA comes free with the Enterprise Edition of the Oracle RDBMS and, not only is it easier to implement, FGA does not have the performance impact of PeopleSoft’s native auditing.

The program name attribute (V$SESSION.PROGRAM) is not by default passed to Oracle’s audit logs. It can be optionally included. To do so, apply Patch 7023214 on the source database. After the patch is applied, the following event needs to be set:

ALTER SYSTEM SET
           EVENT='28058 trace name context forever'
           COMMENT='enable program logging in audit trail' SCOPE=SPFILE;

The table below summarizes key session attributres (V$SESSION) that are passed/not passed to Oracle auditing

Once traffic is accepted and passed by the URL Firewall, WebLogic initiates the standard Oracle E-Business Suite authentication and authorization procedures. Web services are authenticated and authorized no differently than for end-users.

Service-Level ALCs is a new feature of the 12.2 Listener that allows every database service to have its own ACL. The ACL must be based on IP addresses and this feature allows multitenant pluggable databases (PDBs) to each have an ACL enforced by the Listener. This is because each PDB is a unique service registered in the Listener.

To implement this feature a new parameter FIREWALL must be used and has the following options:

In October 2002 Integrigy first posted a guide to securing the Oracle Listener. Since then this whitepaper has been our most popular download. This month we rewrote the whitepaper for Oracle 12c, inclusive of 12.2

Integrigy Consulting has found the Database Listener to be one of the most frequently overlooked security risks at customers. This whitepaper is an overview of the Database Listener, its unique security risks, and step-by-step recommendations for securing it are provided.
