Real Application Security in Oracle

 Real Application Security in Oracle

Real Application Security (RAS) is a feature in Oracle Database that provides fine-grained access control for database resources. RAS allows you to define and enforce security policies that restrict access to specific database objects and actions.

Here is an example of using RAS to create a security policy:

BEGIN

   DBMS_RLS.ADD_POLICY(

      object_schema => 'hr',

      object_name => 'employees',

      policy_name => 'emp_policy',

      function_schema => 'my_schema',

      policy_function => 'my_function',

      statement_types => 'SELECT'

   );

END;

/

This example creates a security policy named "emp_policy" that restricts access to the "employees" table owned by the "hr" user. The policy uses a function named "my_function" defined in the "my_schema" schema to enforce the access control rules. The policy is applied to SELECT statements that access the "employees" table.
