Oracle Database 12c: Security 13 — 3

Enabling and Managing OLS

•Register and enable OLS:
– Using DBCA or
– Executing the LBACSYS.CONFIGURE_OLS and LBACSYS.OLS_ENFORCEMENT.ENABLE_OLS procedures
•The The LBACSYS schema owns all OLS objects.
•Use Enterprise Manager Cloud Control (EMCC) SQL*Plus to manage the Label Security policies.
•In PDBs, which canhttp://orabase.org/wp-admin/edit-tags.php?taxonomy=post_tag be plugged in and out of CDBs:
– Manage OLS components on a subset of PDBs in a CDB:
— Policies (no policies in the root)
— Data labels
— User authorizations
– The LBACSYS schema is a common user schema.
– LBACSYS objects are automatically available to any PDB.

OLS: Features

OLS provides:
• Row-level security based on Virtual Private Database (VPD) technology
– All required packages for access mediation
– Complete data dictionary for managing OLS components
•A complete infrastructure for managing label security policies, sensitivity labels, and user security clearances
• Enterprise Manager pages containing a graphical user interface for managing OLS
• Integration with Oracle Identity Management starting Oracle Database 10g Release 1

OLS is built on the fine-grained access control technology of VPD. The major advantage of using OLS is that OLS is a complete system. It is a ready-to-use VPD. OLS provides sophisticated functions and procedures for evaluating and comparing sensitivity labels. It provides a sophisticated infrastructure for storing and managing sensitivity labels and user security clearances.
