access-control-rbac

Role-based access control (RBAC) assigns permissions to roles, then grants roles to users. Define roles with specific permissions, assign users to roles, and check permissions during requests. This Skill provides policy evaluation patterns and integration examples for Node.js, Python, and Java frameworks.

RBAC grants access based on assigned user roles and their associated permissions. ABAC makes decisions using user, resource, and environment attributes. This Skill covers both approaches with policy examples and evaluation logic for scenarios requiring fine-grained authorization beyond simple role assignment.

Yes. This Skill handles multi-tenant architectures, role hierarchies, and policy conflict resolution. It provides patterns for isolating tenant data, managing role inheritance, and enforcing deny-by-default semantics across admin dashboards and enterprise systems.

Integrate access control by performing permission checks before executing API endpoints. This Skill includes integration patterns for REST APIs and microservices using Node.js RBAC, Python ABAC, and Java Spring Security implementations with policy evaluation at request time.

Policy conflicts arise when multiple rules apply to the same request with different outcomes. This Skill covers conflict resolution strategies, deny-by-default semantics to handle ambiguity safely, and policy evaluation logic to ensure consistent, secure authorization decisions.
