ORACLE's Approach ORALCE uses a proprietary mechanism for security. They user OLS.... ORACLE Labeling Security. They do data confidentiality They do adjudication They do auditing All at the proprietary database level. A for pay solution, not based on open standards.

AUDITING Audit & monitor database activity Logon failures, privilege usage, data access, object access,and other activities Standard Audit Trail (over 250 audit actions) Gives first level of information about access to the database Statement auditing Privilege auditing Schema Object auditing Fine-Grained Auditing (FGA) Gives second level of information about specific operations to the database Enables you to monitor data access based on content. Oracle Database 10g Auditing

Fine-grained auditing (FGA) Beginning with Oracle9i Database, Oracle provides the capability to audit specific rows within a table. This is accomplished using the DBMS_FGA package. Features Attach audit policy to table or view Specify audit condition using a SQL predicate User’s query text with bind variables are written to audit record upon a triggering audit event Event handler can alert administrator to triggering condition (e.g. write record to log, send page)
