什么是AuthorizationPolicy
授权功能是 Istio 中安全体系的一个重要组成部分,它用来实现访问控制的功能,即判断一个请求是否允许通过,这个请求可以是从外部进入 Istio 内部的请求,也可以是在 Istio 内部从服务 A 到服务 B 的请求。可以把授权功能近似地认为是一种四层到七层的“防火墙”,它会像传统防火墙一样,对数据流进行分析和匹配,然后执行相应的动作。
流程
Authorization policies support ALLOW
, DENY
and CUSTOM
actions. The policy precedence is CUSTOM
, DENY
and ALLOW
. The following graph shows the policy precedence in detail:
资源详解
Field | Type | Description | Required |
---|---|---|---|
selector | WorkloadSelector | Optional. Workload selector decides where to apply the authorization policy. If not set, the authorization policy will be applied to all workloads in the same namespace as the authorization policy. | No |
rules | Rule[] | Optional. A list of rules to match the request. A match occurs when at least one rule matches the request.If not set, the match will never occur. This is equivalent to setting a default of deny for the target workloads. | No |
action | Action | Optional. The action to take if the request is matched with the rules. | No |
provider | ExtensionProvider (oneof) | Specifies detailed configuration of the CUSTOM action. Must be used only with CUSTOM action. | No |
允许nothing
allow-nothing.yaml
apiVersion: security.istio.io/v1beta1
kind: AuthorizationPolicy
metadata:
name: allow-nothing
spec:
# This matches nothing, the action defaults to ALLOW if not specified.
{}
The following example shows an ALLOW
policy that matches nothing. If there are no other ALLOW
policies, requests will always be denied because of the “deny by default” behavior.
默认拒绝,有通过则通过
全局拒绝所有
kubectl apply -f global-deny-all.yaml -n istio-system

action
Name | Description |
---|---|
ALLOW | Allow a request only if it matches the rules. This is the default type. |
DENY | Deny a request if it matches any of the rules. |
AUDIT | Audit a request if it matches any of the rules. |
CUSTOM | The CUSTOM action allows an extension to handle the user request if the matching rules evaluate to true. The extension is evaluated independently and before the native ALLOW and DENY actions. When used together, A request is allowed if and only if all the actions return allow, in other words, the extension cannot bypass the authorization decision made by ALLOW and DENY action. Extension behavior is defined by the named providers declared in MeshConfig. The authorization policy refers to the extension by specifying the name of the provider. One example use case of the extension is to integrate with a custom external authorization system to delegate the authorization decision to it.Note: The CUSTOM action is currently an experimental feature and is subject to breaking changes in later versions. |

Dependency on mutual TLS
Istio uses mutual TLS to securely pass some information from the client to the server. Mutual TLS must be enabled before using any of the following fields in the authorization policy:
- the
principals
andnotPrincipals
field under thesource
section - the
namespaces
andnotNamespaces
field under thesource
section - the
source.principal
custom condition - the
source.namespace
custom condition
Mutual TLS is not required if you don’t use any of the above fields in the authorization policy.
