Implementing Siebel Business Applications on DB2 UDB for z/OS > Security Concepts for z/OS >

Operating System Security

The DB2 Connect middleware passes the user ID and password used to access Siebel Business Applications to DB2 to establish a connection. The user ID and password can be user credentials supplied by the external security adapter, if you are using an external security adapter.

The Security Administrator on z/OS must preregister all user IDs and passwords passed through DB2 Connect with the z/OS security package in use, for example, RACF, ACF/2, or TOP SECRET. The z/OS Security Administrator can associate the user ID with a secondary authorization ID (also known as the Security Group ID on the Deployment Planning Worksheet) within the z/OS security package to simplify database security privilege administration.

DB2 Connect supports password encryption on the DB2 for z/OS platform.

NOTE:  The password rules for Siebel user IDs for DB2 are determined by the operating system security interface (RACF, ACF/2, or TOP SECRET).
