Dynamic Authorization Policies in Keycloak

Dynamic authorization policies in Keycloak enable real-time, context-aware access control that goes beyond static role-based permissions. By evaluating factors like user attributes, location, time, and device type, Keycloak ensures secure and flexible access to sensitive resources.

Key Points:

• Dynamic Authorization: Access decisions are made in real-time based on multiple conditions, such as user roles, environmental factors, and resource sensitivity.
• Keycloak’s Features: Supports Attribute-Based Access Control (ABAC), Role-Based Access Control (RBAC), and more, allowing fine-grained, reusable policies.
• Policy Components: Resources (what is protected), Scopes (actions allowed), Policies (conditions for access), and Permissions (linking resources/scopes to policies).
• Use Cases: Ideal for enterprises needing granular control for compliance (e.g., SOC 2, HIPAA) or managing multi-tenant environments.
• Automation and Management: Policies can be managed programmatically via APIs, and auditing tools ensure compliance.

Dynamic policies help organizations meet modern security demands while maintaining efficiency. Managed platforms like Skycloak simplify implementation and scaling.

Core Components of Keycloak Authorization

Keycloak’s approach to authorization revolves around four key elements that enable it to adapt access decisions dynamically. These components work together to provide precise and flexible access control, supporting a variety of scenarios.

Resources, Scopes, Policies, and Permissions

Keycloak’s authorization framework is built on four fundamental components that range from simple role checks to intricate access decisions.

• Resources: These are the objects or entities you want to protect, such as API endpoints (/account/{id}, /users/*), web pages, files, or even specific pieces of data. Resources can also be grouped and contain attributes that aid in policy evaluation. Additionally, they can have owners, which is useful for implementing attribute-driven policies.
• Scopes: Scopes define the specific actions that users can perform on a resource, such as view, edit, delete, or create. This allows for fine-grained control. For example, a marketing team member might have read access to customer data but no permission to delete it.
• Policies: Policies set the conditions for granting access. For instance, you could create a “Business Hours Only” policy to restrict access to certain resources during specific times. Keycloak supports several policy types, including Role-Based, Attribute-Based, User-Based, Context-Based, and Time-Based.
• Permissions: Permissions link resources and scopes to policies, answering the question: “What is being protected, and under what conditions is access allowed?”. This ensures that access decisions are dynamic and can adapt to changing requirements.

Policy Types in Keycloak

Keycloak provides a variety of built-in policy types to handle different authorization needs:

• Role-based policies: These check whether a user has specific roles assigned. They can also be combined with other policy types for more complex scenarios.
• User-based policies: These are designed for exceptions or special cases, such as granting the CEO access to all financial reports, regardless of their formal role.
• JavaScript policies: These allow for custom logic, incorporating user attributes, environmental factors, and external data. For example, a JavaScript policy might ensure that sensitive data is accessed only from approved locations during authorized hours.
• Time-based policies: These restrict access based on time, such as limiting access to payroll systems outside business hours.
• Aggregated policies: These combine multiple policies using logical operators (AND, OR). For instance, you might require a user to hold a specific role, access data during business hours, and obtain managerial approval.
• Group, Client, and Client Scope policies: These leverage organizational structure or application architecture, making them useful in multi-tenant setups or for managing access across several applications.
• Regex policies: These handle pattern-matching scenarios. When built-in policy types aren’t enough, Keycloak also supports custom policy providers.

Once policies are defined, Keycloak evaluates them systematically to enforce secure access.

Policy Evaluation Process

When a client requests access to a resource with a specific scope, Keycloak follows a structured evaluation process to determine whether access should be granted. The process begins by identifying the permissions tied to the requested resource and scope. Each permission then triggers the evaluation of its related policies. This dynamic process ensures that conditions are checked in real time.

Keycloak uses two main types of permissions:

• Resource-based permissions: These apply to a specific resource or all resources of a certain type. For example, you could grant all finance team members access to financial reports.
• Scope-based permissions: These focus on specific actions (scopes) and can be limited to particular resources. For instance, managers might be allowed to edit employee records, but only for their direct reports.

During evaluation, each policy has a Logic value, either Positive or Negative, which determines whether the policy’s result is used directly or inverted. The combined evaluations, along with decision strategies set at the resource server and permission levels, ultimately decide whether access is granted. This layered approach ensures that authorization decisions meet an organization’s complex security needs while maintaining the speed required for real-time operations.

Creating and Managing Dynamic Authorization Policies

This section dives into how you can leverage Keycloak’s core components to design and manage flexible authorization policies, ensuring streamlined setup and effective governance.

Setting Up Authorization in Keycloak

Dynamic authorization starts with enabling Keycloak’s authorization services. In the Keycloak Admin Console, navigate to your client configuration and activate the Authorization setting. This automatically sets up the framework, including an Authorization tab where you can manage policies.

Once enabled, define your resources – these represent the objects or endpoints you want to secure. For example:

• /api/financial-reports/{id}
• /api/user-accounts
• /api/audit-logs

Next, configure scopes, which define the actions users can take. Examples include read, write, delete, approve, and export. If you’re working with a healthcare application, you might use view-patient-data, edit-medical-records, or access-billing-info.

Start by creating role-based policies. For instance, a “Finance Team Access” policy grants access to financial data. Add conditions for more granular control, such as a time-based policy named “Business Hours Only”, which limits access to weekdays between 8:00 AM and 6:00 PM EST.

Finally, tie everything together with permissions. For example, a permission called “Financial Reports Access” might combine the financial reports resource with read and export scopes. It could enforce both the “Finance Team Access” and “Business Hours Only” policies using an AND decision strategy.

With this foundational setup, you’re ready to add more nuanced control by blending RBAC and ABAC.

Combining RBAC and ABAC for Detailed Control

To achieve more context-aware access control, merge Role-Based Access Control (RBAC) with Attribute-Based Access Control (ABAC). This approach allows you to adapt access based on specific conditions while keeping role-based rules as the backbone.

Start by defining roles like financial-analyst, hr-manager, or security-officer that align with job responsibilities. Then, enhance these with attribute-based rules. For example, user attributes such as department, clearance-level, employment-type, or location can refine access policies. A JavaScript policy might check if an hr-manager is accessing employee records from their department during business hours and from an approved IP range.

You can also enforce context-driven restrictions. For example:

• Sensitive customer data might only be accessible from corporate networks during business hours.
• Remote access could require multi-factor authentication.

Dynamic decisions can also rely on resource attributes. For instance, if resources are tagged with attributes like confidentiality-level or data-owner, policies can determine access accordingly. A manager might view all documents in their department, but only senior leaders can access files tagged as “executive-only.”

Use aggregated policies to combine multiple conditions. For example, accessing financial forecasts might require the following:

• The financial-analyst role
• Access during business hours
• Connection from an approved location
• Recent completion of security training (tracked as a user attribute)

This layered approach ensures precise and adaptable access control.

Best Practices for Policy Management

As your authorization system grows, managing policies effectively becomes essential. Here are some strategies to keep everything organized and efficient:

• Use Clear Naming Conventions: Descriptive names make policies easier to understand. For example, “Finance-Dept-Quarterly-Reports-Access” or “HR-Employee-Records-Business-Hours-Only.” Include version numbers or dates for tracking changes.
• Organize Policies Logically: Group related policies based on business structure or data classification. For instance, prefix HR policies with “HR-” and time-based restrictions with “Time-” to simplify navigation.
• Document Policies: Maintain records of why each policy exists, the business requirements it addresses, and the contact information for the policy owner. This helps with audits and troubleshooting.
• Version Policies: Instead of editing critical policies directly, create new versions. This provides an audit trail and allows quick rollbacks if needed.
• Test in Development: Before deploying policies, test them thoroughly in a controlled environment. Cover both positive and negative scenarios, focusing on edge cases and interactions between policies.
• Monitor Performance: Complex policies, like those using JavaScript or external API calls, can slow down response times. Consider caching commonly used attributes or pre-computing results to improve performance.
• Regular Reviews: Schedule periodic reviews to identify unused policies, consolidate overlapping rules, and ensure alignment with current business needs. Remove outdated policies to reduce complexity and improve efficiency.

Advanced Use Cases and Integration Examples

Keycloak’s dynamic authorization policies shine in handling complex, real-world situations. By tapping into its flexibility, organizations can implement secure, dynamic access control tailored to their needs. Multi-tenant environments, in particular, demand advanced strategies to address their unique challenges.

Multi-Tenant Access Control

Managing access in multi-tenant applications brings specific hurdles, especially in ensuring data isolation and defining resource-specific permissions. Keycloak’s Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC) systems provide solid frameworks to tackle these challenges.

For organizations prioritizing strict tenant isolation, creating separate realms for each tenant is the most secure option. This setup ensures full data segregation and independent policy management, making it an excellent choice for enterprise SaaS platforms operating under strict regulatory standards.

In cases where users need access to multiple tenants, a single realm with scoped roles offers a more flexible solution. This approach allows administrators to assign tenant-specific roles while keeping user management centralized. For example, a user might be assigned an “admin” role for Tenant A and a “viewer” role for Tenant B, all within the same Keycloak realm.

Keycloak’s JSON Web Tokens (JWTs) play a vital role in multi-tenant setups. These tokens embed user and tenant context as claims, which backend systems can use to enforce tenant-specific operations. This method ensures consistent authorization decisions across distributed services while maintaining clear tenant boundaries.

For scenarios requiring highly dynamic and fine-grained multi-tenant controls, Keycloak’s built-in capabilities may need to be supplemented with custom authorization logic. This approach addresses its limitations in handling more detailed policies, such as those requiring relationship-based access control (ReBAC).

Tools like Skycloak simplify the deployment of advanced authorization patterns. Their Growth plan, priced at $1,000 per month, includes pre-configured templates, custom extension plugins, and advanced monitoring features. These services provide enterprise-grade reliability and support for implementing sophisticated access control strategies.

Conclusion

This guide highlights how Keycloak’s dynamic authorization policies transition from traditional, static role-based models to smarter, context-aware controls. By leveraging Keycloak’s robust authorization framework, organizations can craft security systems that adjust to the demands of modern business environments.

Key elements – like resources, scopes, policies, and permissions – serve as the building blocks for a flexible security structure. The combination of RBAC (Role-Based Access Control) and ABAC (Attribute-Based Access Control) enables fine-tuned, context-sensitive permissions that factor in user attributes, environmental conditions, and specific business needs during authorization decisions.

FAQs

What makes Keycloak’s dynamic authorization different from traditional role-based access control (RBAC)?

Keycloak’s dynamic authorization takes access control to the next level by making real-time, context-sensitive decisions instead of depending solely on static roles or permissions. Traditional role-based access control (RBAC) assigns users fixed roles, but dynamic authorization evaluates a variety of factors – like user attributes, current environmental conditions, and specific resource details – to decide access on the spot.

This method offers more flexibility and accuracy in managing access for complex systems. By adjusting permissions dynamically based on the situation, it strengthens security and ensures access is granted only when it’s genuinely appropriate, overcoming the rigid limitations of static RBAC models.

What are the best practices for creating and managing dynamic authorization policies in Keycloak?

To set up and manage dynamic authorization policies in Keycloak effectively, start by leveraging roles for broad permission assignments. Then, use attributes to implement more detailed and specific access controls. This combination allows you to handle user access with both flexibility and precision.

Keycloak also offers powerful tools like built-in policy enforcers and resource-based policies, which let you create rule-driven permissions that can be customized to fit your application’s unique requirements.
