Agenda
The GCC Business Case
The Security problem & the approach taken
Setting up the Infrastructure
Enabling ADF Security
Enabling Per Project & Module Security in ADF


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 Team
4 Engineers & Developers
1 ADF dedicated since 2 years + Forms/Reports (6yrs)
1 ADF dedicated since 1 year
1 Forms/Reports dedicated +20yrs
2 dealing with overall infrastructure: DB,AS,Firewalls..

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


Dev Started 1990, kept updated & still growing…

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


Connecting Sites to the GCC System
with ADF Web applications


The Security Problem &
The approach taken


Corporate User works Site User always
transversely across works under a Project
projects Context


Security is delegated to
“Line of Service” Managers

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)


Blocks involved to implement :
OID/SSO, Database, ADF Security & UI

OID (LDAP) for USERS and MODULE GROUPS
ORACLE 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


Delegation of management of Project/Module Security

Module Security
Manager


Security Management related Forms
Modules
Who can Manage a Module for one or more Projects

OID Group

Module Roles & related privileges
Grant/Revoke Module Roles to User for Project

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

Other advantages of using the Database is
the 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


How to integrate OID/SSO with WebLogic
“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.”

Oracle WebTier 11g Oracle Identity Management 10.1.4

Webcache wls1034.gcc.mu:7785 Oracle Single Sign-on/OID

HTTP 11g wls1034.gcc.mu:7777

ADF 11g deployment
WebLogic wls1034.gcc.mu:7007


Proxying WebLogic with HTTP 11g

Webcache wls1034.gcc.mu:7785



Register HTTP server With the OSSO Infra Server

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


Setup WebLogic Security Providers

Authenticator must be configured
Oracle WebTier 11g
for Oracle Internet Directory (OID)

Identity Assertion Provider must be
IdM
configured for SSO


WebLogic Realm Security Providers


Infrastructure Setup Done

Oracle WebTier 11g Oracle Identity Management 10.1.4

Webcache wls1034.gcc.mu:7785 Oracle Single Sign-on/OID


ADF 11g deployment


Enabling ADF Security


What is done at the back...

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

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


Authorization : Roles & Pages Security

Application Roles
ADF application specified role, ADF Authorization are set on these roles.

Enterprise Roles
Roles assigned to the ADF user from the Credential/Identity Store (Oracle
Internet Directory)

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

Roles are applied to pages with “View” permission
Other permissions are only applicable if you use WebCenter


Authorization (Jazn-data.xml)


What we have at this stage

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).

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


Enabling Per Project &
Module Security in ADF


Application navigation use case
(Apps screenshots)


Oracle Single Sign-On Login Form

Oracle Infrastructure 10.1.4 Default Login Form
Customized with our logo.
One could write a custom Login Form


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

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

Module

User can switch Project Context
Within the Same Module

Actions available or not depending on User’s
rights on this specific Project and Module

Oracle Reports integration (Report TaskFlow)

Oracle Report Parameter Form

Report URL not displayed


How it works (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 Future
Potential grounds for improvements

Oracle Access Manager
When Forms/Reports support it

Oracle WebCenter
Application Entry point (Portal) + Customization for tasks shortcuts (Approving Requests etc..)
Improve Application Structure using Catalogs
Content Integration & Web 2.0 features
(ex: Project Site Communications Module extended with Chat/Forum/Workspace)

ADF Mobile
Pervasiveness of our Applications (ex: allowing an approval anywhere on site)

Thank You.


VOs Bind Variables are automatically replaced
by our parameters value to filter data per Project at VO level
Parameter naming convention : Parameter name must be consistent,
For ex. a projectCode parameter defined in the AM must have the same name as
the VO bind variable name.
All ViewObjects use a custom based class “BaseFilteredViewObject” where
executeQuery and executeQueryForCollection are overridden :
setGlobalVariablesValues();
super.executeQuery();

private void setGlobalVariablesValues() {
VariableValueManager vm = ensureVariableManager();
Variable[] vars =
vm.getVariablesOfKind(Variable.VAR_KIND_WHERE_CLAUSE_PARAM);

for (Variable var : vars) {
Object voVarValue = vm.getVariableValue(var.getName());
if (voVarValue == null || voVarValue.toString().isEmpty()) {
vm.setVariableValue(var.getName(),
getApplicationModule().getSession().getUserData().get(var.getName()));
}
}
}
