The Business Case

The GCC Business Building & Civil Engineering

GCC = Main Contractor = Builders Work mainly

Operations in Mauritius Only

~3000 Workforce, ~400 Staff (200 HQ, 200 on Sites).

The GCC IT Team4 Engineers & Developers

1 ADF dedicated since 2 years + Forms/Reports (6yrs) 1 ADF dedicated since 1 year 1 Forms/Reports dedicated +20yrs (new/reviews &

upgrades) 2 of them dealing with overall infrastructure

(Installation, Admin of DB,AS,Storage,DR,Firewalls,...)

2 Desktop & Peripheral Support Technicians Sites NetworkingDesktop/Clients Configs & Support

Dev Started 1990, Kept Updated & Still Growing…

ORACLE FORMS&

ORACLE REPORTS

SINGLE ORACLE DATABASE INSTANCE

Today ~1500 Forms & 1500 Reports covering most aspects of line of

services/business units(Logistics, Professional Support &

Coorporate Services) each backing up Sites Operations

Need for our Sites to be Active Players

in this Services Ecosystem

We saw there a good case for an ADF transition

Started with ADF 10g, 2 years ago

Connecting Sites to the GCC System with ADF Web applications

As we grow with ADF we will replace FORMS slowly across the whole IS

ORACLE ADF&

REPORTS&

FORMS

Security Approach for the overall Ecosystem

Site User always works under a Project ContextCompared to a Corp.User who works

transversely across projects

Security delegated to “Line of Service” Managers where applicable

•Each “Line of Service” Manager makes service agreements with Sites defining how they will work :-Who will do what.

•“Line of Service” Manager applies Agreement by setting roles in a Security Configuration/Management application.

Security Model for all applications (ADF, Forms & Reports)

4 “Levels”: OID/SSO, Database, ADF Security & UI

OID (LDAP) for USERS and MODULE GROUPSORACLE Single Sign-On (SSO)

DATA MODEL FOR A SECURITY APPLICATION TO DRIVE PER MODULE/PROJECT ROLES

ADF SECURITY FOR PAGES ON OID GROUPS

ADF UI COMPONENTS RENDERED OR NOT USING EL :CUSTOM CLASSES TO CHECK ROLES FROM THE DATABASE

Security ApplicationBuilt with both Forms & ADF

to support delegation to Line of Service Managers

Users stored in Database + mirrored in OIDusing dbms_ldap package

OID Data

Delegate management of Project/Module Security

Module Security Manager

Who can Manage a Module for one or more Projects

Grant/Revoke Module Roles to User for Project

OID Group

Security Management related Forms

Module Roles & related privileges

Modules

When access granted to a first Site, OID updated with module group using dbms_ldap package

Other advantages of using the Database isthe integration of security with HR Data

New Users are added to the Site from HR Employees data by the Security manager.

Auditing Accesses inside the database and Timesheet cross-checking (Absent but logged on, not assigned to a Site but still

authorized etc..)

When an employee leaves the company, authorization is automatically revoked

Ability to do more control as & when needed/decided

Security Data is backed up with Database

Setting up the Infrastructure

WebLogic, OID & SSO

What we need to integrate OID/SSO with WebLogic

Webcache wls1033.gcc.mu:7785

HTTP 11g wls1033.gcc.mu:7777

WebLogic wls1033.gcc.mu:7007

Oracle Single Sign-on/OID

Oracle WebTier 11g

ADF 11g deployment

Oracle Identity Management 10.1.4

“Forms (11g) will not be specifically coded to use, nor tested with Oracle Access Manager. Other Oracle products, such as ADF, Web Center and Portal, will also support Oracle Single-Sign-on.

Oracle has plans to support Oracle Access Manager in future versions of Oracle Forms 11g.”

Proxying WebLogic with HTTP 11g




Register the weblogic server URL with webcache port (7785) on the OID/SSO Server :-

1/.Create a wls_osso.conf file from the ssoreg.sh tool on the OID/SSO infra server .

2/.Replace the Weblogic server webtier osso.conf with the generated file

3/.Configure mod_osso.conf to point to the newly copied osso.conf

Register HTTP serverWith the OSSO Infra Server

Setup WebLogic Security Providers

o Authenticator must be configured for Oracle Internet Directory (OID)

o Identity Assertion Provider must be configured for SSO

Normal ADF Security(Not Project related yet)

Authentication &

ADF application pages Authorization using OID Groups


Jdeveloper creates :jazn-data.xml: Set security rules & permissions + dev/test store for testing only (skipped on deployment)

What it does ..

and updates :web.xml: Set type of Authentication selected.weblogic.xml : where users are mapped to role (by default a generic principal (user) is mapped to a Weblogic role “valid-users” (authenticated user)adf-config.xml: To indicate that ADF security is enabled & handled by JPS (Java Platform Security)

Authentication Type (web.xml) with Oracle Infrastructure Single sign-on

Remember this is due to Forms/Reports integration & the following Oracle statement:

Authorization : Roles & Pages Security

oApplication RolesADF application specified role, ADF Authorization are set on these roles.

oEnterprise RolesRoles assigned to the ADF user from the Credential/Identity Store (Oracle Internet Directory)

oApplication Role is mapped to Enterprise Role allowing developer to use roles and map them later to final Roles.

oRoles are applied to pages with View permissionOther permissions are only applicable if you use WebCenter

Authorization (Jazn-data.xml)

What we have at this stage

o A user with an OID account and OID Groups (enterprise roles) gets a SSO login form to identify himself when trying to access an ADF application (all pages being protected by ADF Security).

o Once authenticated, he can navigate to the page if he has the necessary enterprise role (mapped to the application role set to protect the page).

On each page, we only want the authorized UI components

to be rendered.

UI components level Rendering or not a UI component (button, panel etc..)

JSF Expression Language (EL)

CurrentPeriod <= (le for less or equal) Period

#{securityContext.userInRole[‘rolename’]} for “static” role

We will see later how we use EL to apply per project security

Enabling Per Project & Module Security in ADF

Before proceeding let’s see a normal navigation use case demo of the

application

Oracle Single Sign-On Login Form

Oracle Infrastructure 10.1.4 Default Login FormCustomized with our logo.

We could (& should) write a custom Login Form

List of Projects for which the user is entitled to at least one Application Module

Was done with ADF 10g, 11g was not yet released. Currently being upgraded to 11g

Last Project accessed by the User in last session

List of Modules to which the user is entitled to on the selected Project

Was done with ADF 10g, 11g was not yet released. Being upgraded to 11g

User can switch Project ContextWithin the Same Module

Module

Ex: Button rendered or not depending on User’s rights on this specific Project

Module

Oracle Reports integration(Report TaskFlow)

Report URL not displayed

Oracle Report Parameter Form

What we do(Guideline only. To Show extensibility/flexibility of the Framework)

1. User Login is fetched from ADF Context.

2. From a “Project List” module and a “Project Switcher” Taskflow, a selected Project is set in the database. Any direct access to Module takes the Project from the database.

3. When accessing an application we store in the AM Session our context parameters: Project Code, User Login, Module Code,etc..

4. Module Access Right for Project is checked from the database (in case Module accessed directly via Module URL)

5. Database Client Identifier & Module Environment are set in the Database for Auditing purpose & other needs.

6. A “Module access” audit event is logged in the Database

7. When a page is accessed, session parameters are stored (if not already done) in a Session bean.

8. User’s Privileges Codes for Module/Project is fetched from the Security Database and stored in HTTP session as a Map.

9. Bind Variables on our View Objects (VOs) are automatically replaced by our parameters value to filter data at VO level when VOs are executed.

10. We have a session bean method (SecurityScope.userinRole) that is used in EL to check Privileges from our HTTP session Map to Render or not a Component.

Normal EL Expression to check from static role

#{securityContext.userInRole[‘Role Name']}

Custom EL Expression to check from Database privileges Codes assigned to Role

#{securityScope.userInRole[‘Priv List Code']}

The FuturePotential grounds for improvements

Move to Oracle Access Manager (When Forms/Reports support it) &investigate/try to leverage Oracle Entitlement Server“Oracle Entitlements Server is a fine grained authorization engine that externalizes, unifies, and simplifies the management of complex entitlement policies”
