Excalibur.A3.Policy.Cedar

Cedar policy engine HTTP adapter for the Excalibur A3 authorization framework.

Overview

This package implements IAuthorizationEvaluator by delegating policy decisions to a Cedar policy engine over HTTP. Supports both local Cedar agents and Amazon Verified Permissions (AVP).

Quick Start

Local Cedar Agent

services.AddExcaliburA3(a3 =>
{
    a3.UseCedarPolicy(cedar =>
    {
        cedar.Endpoint = "http://localhost:8180";
        cedar.Mode = CedarMode.Local;
        cedar.TimeoutMs = 5000;
        cedar.FailClosed = true;
    });
});

Amazon Verified Permissions

services.AddExcaliburA3(a3 =>
{
    a3.UseCedarPolicy(cedar =>
    {
        cedar.Endpoint = "https://verifiedpermissions.us-east-1.amazonaws.com";
        cedar.Mode = CedarMode.AwsVerifiedPermissions;
        cedar.PolicyStoreId = "ps-abc123";
        cedar.FailClosed = true;
    });
});

Features

  • Dual mode: Local Cedar agent or Amazon Verified Permissions
  • Fail-closed by default: HTTP errors, timeouts, and malformed responses result in denial
  • No AWS SDK dependency: AVP endpoint uses raw HTTP for lightweight integration
  • IHttpClientFactory integration: Managed HTTP client lifetime with proper pooling
