It will reject a request if the request contains invalid authentication information, based on the
configured authentication rules. A request that does not contain any authentication credentials
will be accepted but will not have any authenticated identity. To restrict access to authenticated
requests only, this should be accompanied by an authorization rule.
Examples:</p><p>Require JWT for all request for workloads that have label <code>app:httpbin</code>:</p><pre><code class=language-yaml>apiVersion: security.istio.io/v1
kind: RequestAuthentication
metadata:
name: httpbin
namespace: foo
spec:
selector:
matchLabels:
app: httpbin
jwtRules:
- issuer: &quot;issuer-foo&quot;
jwksUri: https://example.com/.well-known/jwks.json
---

kind: AuthorizationPolicy
metadata:
name: httpbin
namespace: foo
spec:
selector:
matchLabels:
app: httpbin
rules:
- from:
- source:
requestPrincipals: [&quot;*&quot;]
</code></pre><p>A policy in the root namespace (&ldquo;istio-system&rdquo; by default) applies to workloads in all namespaces
in a mesh. The following policy makes all workloads only accept requests that contain a
valid JWT token:</p><pre><code class=language-yaml>apiVersion: security.istio.io/v1
kind: RequestAuthentication
metadata:
name: req-authn-for-all
namespace: istio-system
spec:
jwtRules:
- issuer: &quot;issuer-foo&quot;

---

kind: AuthorizationPolicy
metadata:
name: require-jwt-for-all
namespace: istio-system
spec:
rules:
- from:
- source:
requestPrincipals: [&quot;*&quot;]
</code></pre><p>The next example shows how to set a different JWT requirement for a different <code>host</code>. The <code>RequestAuthentication</code>
declares it can accept JWTs issued by either <code>issuer-foo</code> or <code>issuer-bar</code> (the public key set is implicitly
set from the OpenID Connect spec):</p><pre><code class=language-yaml>apiVersion: security.istio.io/v1
kind: RequestAuthentication
metadata:
name: httpbin
namespace: foo
spec:
selector:
matchLabels:
app: httpbin
jwtRules:
- issuer: &quot;issuer-foo&quot;
- issuer: &quot;issuer-bar&quot;
---
apiVersion: security.istio.io/v1
kind: AuthorizationPolicy
metadata:
name: httpbin
namespace: foo
spec:

matchLabels:

- from:
- source:
requestPrincipals: [&quot;issuer-bar/*&quot;]
to:
- operation:
hosts: [&quot;another-host.com&quot;]
</code></pre><p>You can fine-tune the authorization policy to set different requirement per path. For example,
to require JWT on all paths, except /healthz, the same <code>RequestAuthentication</code> can be used, but the
authorization policy could be:</p><pre><code class=language-yaml>apiVersion: security.istio.io/v1
kind: AuthorizationPolicy
metadata:
name: httpbin
namespace: foo
spec:
selector:
matchLabels:
app: httpbin
rules:
- from:
- source:
requestPrincipals: [&quot;*&quot;]
- to:
- operation:
paths: [&quot;/healthz&quot;]
</code></pre><p>[Experimental] Routing based on derived <a href=/v1.24/docs/reference/config/security/conditions/>metadata</a>
is now supported. A prefix &lsquo;@&rsquo; is used to denote a match against internal metadata instead of the headers in the request.
Currently this feature is only supported for the following metadata:</p><ul><li><code>request.auth.claims.{claim-name}[.{nested-claim}]*</code> which are extracted from validated JWT tokens.
Use the <code>.</code> or <code>[]</code> as a separator for nested claim names.
Examples: <code>request.auth.claims.sub</code>, <code>request.auth.claims.name.givenName</code> and <code>request.auth.claims[foo.com/name]</code>.
For more information, see <a href=/v1.24/docs/tasks/security/authentication/jwt-route/>JWT claim based routing</a>.</li></ul><p>The use of matches against JWT claim metadata is only supported in Gateways. The following example shows:</p><ul><li>RequestAuthentication to decode and validate a JWT. This also makes the <code>@request.auth.claims</code> available for use in the VirtualService.</li><li>AuthorizationPolicy to check for valid principals in the request. This makes the JWT required for the request.</li><li>VirtualService to route the request based on the &ldquo;sub&rdquo; claim.</li></ul><pre><code class=language-yaml>apiVersion: security.istio.io/v1
