USER for environments using Oracle HTTP Server or ANONYMOUS for environments using the Embedded PL/SQL Gateway The IP_ADDRESS environment variable is the IP address of the client Most people think this will be the IP address of the end user s machine, but in an APEX environment, the database client is actually the Oracle HTTP server This concept is useful in the context of a FGA policy designed to allow only APEX access to the data as the IP address should always be the same However, if someone connects to the database directly with a tool such as SQL*Plus, that session s IP address will be the IP address of the person s PC, not the HTTP server

Now that you have a good idea of what FGA is, let s work through a few examples that get progressively more complex For the following examples, we ll use two schemas: SEC_USER and SEC_ADMIN SEC_USER will own the objects we want to audit, and SEC_ADMIN will own the functions and policies used in our auditing examples Before we can create any policies, we must connect as a DBA and grant SEC_ADMIN execute privileges on the DBMS_FGA package While we re there, lets also grant select on the sysdba_fga_audit_trail view to SEC_ADMIN

EAN-13 Creator In Objective-C

The first example uses a function called IS_APEX_SESSION_ONE that simply checks to make sure the SESSION_USER environment variable is either APEX_PUBLIC_USER or ANONYMOUS, the two most common schemas used for APEX sessions If the SESSION_USER is considered valid, the function returns a 1 (one), or else it returns a 0 (zero) Connect as the SEC_ADMIN user and create the following function:

Right now, this function is just a traditional function and is in no way associated with a FGA policy or a table Execute the following code as the SEC_ADMIN user to create the policy that will tie the previous function to the table we want to audit:

begin dbmS_FGAadd_policy (object_schema object_name
=> 'SEC_USER', => 'EMPLOYEES',
Part IV: Applied Security for Oracle APEX and Oracle Business Intelligence
policy_name audit_condition audit_column statement_types enable end; / => => => => => 'IS_FROM_APEX_POLICY', 'SEC_ADMINIS_APEX_SESSION_ONE = 0', null, 'INSERT,UPDATE,DELETE,SELECT', true);
In simple terms, an audit policy named IS_FROM_APEX_POLICY has been applied to the SEC_USEREMPLOYEES table This policy is enforced on all columns and all INSERT, UPDATE, DELETE, and SELECT statements An audit event is triggered whenever the function IS_APEX_ SESSION_ONE returns a 0 (zero) Since the goal of this policy is to audit any queries not originating from APEX, let s first test this by querying the EMPLOYEES table from the APEX SQL Workshop The SQL Workshop is itself an APEX application and thus falls within the allowed parameters of our policy
-- Executed in the Application Express SQL Workshop select * from employees;
By querying the DBA_FGA_AUDIT_TRAIL, we can determine whether or not the previous query triggered an audit event:
SQL> select timestamp,db_user, client_id, object_schema,object_name, policy_name, scn, sql_text from sysdba_fga_audit_trail; no rows selected
As expected, no audit event was logged Now, let s run the same query once again from SQL*Plus:
SQL> select * from employees;
Now connect as a privileged user and query the Audit Trail table:
SQL> select timestamp,db_user, policy_name, scn, sql_text from sysdba_fga_audit_trail; TIMESTAMP DB_USER POLICY_NAME SCN SQL_TEXT --------- ---------- ------------------- -------- ----------------------08-MAR-09 SEC_USER IS_FROM_APEX_POLICY 4638186 select * from employees
FGA Example 2
For our next FGA example, we ll leverage more session context information to narrow the allowed parameters of the audit condition a bit This time, we will use MODULE to check that the query is coming from a specific APEX application We can also use the SYS_CONTEXT function to determine the IP address of the client that issued the query In this case, the expected client is our HTTP server; any other IP address indicates the query might be coming from another client such as a SQL*Plus connection from an unauthorized workstation
