|
||
自 Istio 1.4 首次发布以来，我们不断改进策略以使其更加灵活，
|
||
包括 <a href=/v1.24/zh/docs/tasks/security/authorization/authz-deny/><code>DENY</code> 操作</a>、
|
||
<a href=/v1.24/zh/docs/tasks/security/authorization/authz-deny/>排除语义</a>、
|
||
<a href=/v1.24/zh/docs/tasks/security/authorization/authz-ingress/><code>X-Forwarded-For</code> 头信息支持</a>、
|
||
<a href=/v1.24/zh/docs/tasks/security/authorization/authz-jwt/>嵌套 JWT 声明支持</a>等等。
|
||
这些特性提高了授权策略的灵活性，但仍有许多场景无法通过该模型支持，例如：</p><ul><li><p>您拥有自己的内部授权系统，该系统无法轻松地被迁移或替换到授权策略中。</p></li><li><p>您想与使用 Istio 中的<a href=/v1.24/zh/docs/reference/config/networking/envoy-filter/>底层 Envoy 配置 API</a>
|
||
（例如 <a href=https://www.openpolicyagent.org/docs/latest/envoy-introduction/>Open Policy Agent</a>
|
||
或 <a href=https://github.com/oauth2-proxy/oauth2-proxy><code>oauth2</code> 代理</a>）
|
||
或者根本无法正常工作的第三方解决方案进行集成。</p></li><li><p>授权策略缺少在您场景中所需的语义内容。</p></li></ul><h2 id=solution>解决方案</h2><p>在 Istio 1.9 中，我们通过引入
|
||
<a href=/v1.24/zh/docs/reference/config/security/authorization-policy/#AuthorizationPolicy-Action><code>CUSTOM</code> 操作</a>实现了授权策略的可扩展性，
|
||
它允许您将访问控制决策委托给外部授权服务。</p><p><code>CUSTOM</code> 操作允许您将 Istio 与外部授权系统集成，
|
||
该系统实现了自己的自定义授权逻辑。下图展示了此集成方式的顶层架构：</p><figure style=width:100%><div class=wrapper-with-intrinsic-ratio style=padding-bottom:48.573838213459645%><a data-skipendnotes=true href=/v1.24/zh/blog/2021/better-external-authz/external_authz.svg title=外部授权架构><img class=element-to-stretch src=/v1.24/zh/blog/2021/better-external-authz/external_authz.svg alt=外部授权架构></a></div><figcaption>外部授权架构</figcaption></figure><p>在进行配置时，网格管理员使用 <code>CUSTOM</code> 操作对授权策略进行配置，
|
||
用于在代理（网关或 Sidecar）上启用外部授权。
|
||
管理员应确认外部身份验证服务已启动且正在运行。</p><p>在运行时中：</p><ol><li><p>请求被代理拦截，代理将根据用户在授权策略中的配置向外部授权服务发送检查请求。</p></li><li><p>外部授权服务将决定是否允许请求通过。</p></li><li><p>如果允许，请求将被继续执行，并将由 <code>ALLOW</code>/<code>DENY</code> 操作定义的任意本地授权强制执行。</p></li><li><p>如果被拒绝，请求将立即被终止。</p></li></ol><p>让我们看一下带有 <code>CUSTOM</code> 操作的示例授权策略：</p><pre><code class=language-yaml data-expandlinks=true data-repo=istio>apiVersion: security.istio.io/v1beta1
