IronAlpine.Security.Authorization

Permission authorization contracts and application-level services for IronAlpine.

Why

This package is the authorization core for non-host-specific layers:

  • Defines permission store contracts.
  • Provides permission checker service abstractions.
  • Keeps business/application layers independent from ASP.NET and EF Core.

Use this package when handlers/services need permission checks but should not know persistence details.

Install

dotnet add package IronAlpine.Security.Authorization

Contracts

  • ISecurityPermissionStore
    • Read permission names by permission-group ids.
  • ISecurityPermissionProjectionSyncStore
    • Write-side sync contract for SecurityPermissionProjection.
    • Implemented by provider packages (for example IronAlpine.Security.Authorization.EFCore).
  • SecurityPermissionProjectionSyncItem
    • Transport model for projection synchronization.
  • IPermissionCheckerService
    • High-level permission check service used by application code.

Program.cs (Core Registration)

builder.Services.AddIronAlpineAuthorization(options =>
{
    options.UseWildcardPermissionMatching = false;
    options.CacheDurationSeconds = 30;
});

Configuration

Section: IronAlpine:Security:Authorization

SecurityAuthorizationOptions

  • UseWildcardPermissionMatching (bool, default: false)
    • Enables matching such as identity.users.*.
    • Keep disabled unless you explicitly model wildcard policies.
  • CacheDurationSeconds (int, default: 30)
    • In-memory check cache duration for permission evaluations.
    • Lower values increase store reads; higher values may delay revocation visibility.

Typical Combination

  1. Register IronAlpine.Security.Authorization in application.
  2. Register an implementation provider:
    • IronAlpine.Security.Authorization.EFCore for EF-backed projections.
  3. Register ASP.NET authorization host package (IronAlpine.Security.AspNetCore) for API policy enforcement.

Projection Sync Pattern

When permission-group change events are consumed, map event items to SecurityPermissionProjectionSyncItem and call sync store:

await _syncStore.ReplacePermissionsAsync(
    permissionGroupId,
    permissions.Select(x => new SecurityPermissionProjectionSyncItem(x.PermissionId, x.PermissionName)).ToArray(),
    cancellationToken);

Troubleshooting

  • No service for ISecurityPermissionStore
    • Register a provider package (Authorization.EFCore) before checker usage.
  • Permission checks always false
    • Verify projection sync is running and permission group claims are present.
  • Unexpected stale results
    • Reduce CacheDurationSeconds or invalidate cache on projection updates.

Best Practices

  • Keep this package in Core/Application layers only.
  • Keep provider-specific packages (EFCore, Redis, etc.) in Infrastructure.
  • Use explicit permission names and avoid wildcard usage unless required by policy design.
