Setting up application-level security in Oracle APEX using Shared Components is a fundamental step to protect your application and its data. Shared Components in APEX provide a centralized location where you can manage authentication and authorization schemes, session state protection, and other security-related features. By configuring these components, you control who can access your application, what users can do, and how sessions are handled. This approach simplifies security management by allowing you to apply consistent rules across your entire application from a single place.

Setting up application-level security in Oracle APEX using Shared Components involves several key steps that allow you to control user authentication, authorization, and session management centrally for your entire application. Here is a detailed guide on how to implement this:
-
Access Shared Components
In your Oracle APEX application builder, navigate to the Shared Components section. This is where you define common settings used throughout your application. -
Create or Configure an Authentication Scheme
Authentication controls how users prove their identity to access your application. In Shared Components, select Authentication Schemes.-
You can use built-in schemes such as "Application Express Accounts," "Database Account," or "Social Sign-In."
-
To create a new scheme, click “Create” and choose the authentication method you prefer.
-
Configure parameters like login URL, logout URL, session timeout, and password policies if applicable.
-
Set the new scheme as the current authentication method for the application.
-
-
Define Authorization Schemes
Authorization schemes control what authenticated users are allowed to do or access. In Shared Components, select Authorization Schemes.-
Create schemes that define rules based on roles, groups, or custom PL/SQL expressions.
-
Use these schemes to protect pages, regions, buttons, or other components by requiring a specific authorization scheme.
-
Examples include role-based access control or checking user privileges stored in database tables.
-
-
Set Up Session State Protection
Session state protection helps prevent URL tampering or unauthorized requests.-
In Shared Components, configure Session State Protection settings.
-
Enable protection for critical pages or items to ensure only valid data modifications are allowed.
-
-
Manage User Roles and Privileges
Although not always managed within APEX itself, you should have a plan to maintain user roles and privileges in your database or an external identity provider. Authorization schemes often refer to these roles for enforcing access control. -
Apply Security to Application Pages and Components
Once authentication and authorization schemes are defined, apply authorization schemes to pages or specific components.-
In the Page Designer, set the Authorization Scheme property of pages or regions to the scheme you created.
-
This ensures only users meeting the criteria can view or interact with those parts.
-
-
Test Your Security Settings
Always thoroughly test your authentication and authorization configurations by logging in as different users or roles to verify access restrictions behave as expected. Setting Up Access Control
Go to Shared Components > Security > Application Access Control.
Define user roles such as Admin, User, or Read-Only.
Assign privileges to each role.
Apply the access control to pages, reports, or actions within the application.
For example, an "Admin" role may have full access, while a "Read-Only" role can only view reports.
Conclusion
Setting up security at the application level using Shared Components in APEX ensures that user access is managed effectively. By implementing authentication, authorization, session protection, and access control, developers can create secure and well-protected applications.

Application > Shared Components
Setting Up Access Control
Go to Shared Components > Security > Application Access Control.
Define user roles such as Admin, User, or Read-Only.
Assign privileges to each role.
Apply the access control to pages, reports, or actions within the application.
For example, an "Admin" role may have full access, while a "Read-Only" role can only view reports.
Conclusion
Setting up security at the application level using Shared Components in APEX ensures that user access is managed effectively. By implementing authentication, authorization, session protection, and access control, developers can create secure and well-protected applications.
EXAMPLE:
Application > Shared Components
By using Shared Components for application-level security, you centralize the management of critical security settings. This approach ensures consistent enforcement across your Oracle APEX application, simplifies maintenance, and improves security robustness.
In conclusion, leveraging Shared Components to set up application-level security in Oracle APEX offers a powerful and flexible way to safeguard your app. Through careful configuration of authentication and authorization schemes, along with session and access controls, you ensure only authorized users can access sensitive areas of your application. Regularly reviewing and updating these settings within Shared Components helps maintain a strong security posture as your application evolves.
