In this CRD we will apply the request authentication in the previous step and, we will go further by decoding the jwt and evaluate other fields. Build the docker image docker build -t auth:v1 . The -k option prevents the client from verifying and looking for the server name i.e, in our case it is auth-test-service.bar.svc.cluster.local in the certificate provided by the server. To enable port level mTLS, the port should be exposed by service like we have a service exposing port 8001 else it is ignored. Shows you how to use Istio authentication policy to route requests based on JWT claims. A vision statement and roadmap for Istio in 2020. Provision and manage DNS certificates in Istio. Lines 1-4 create a service account. Policy to allow mTLS strict for all workloads, but leave port 8080 to Understand Istio authentication policy and related mutual TLS authentication concepts. Well, we contemplated that as we haven't applied an authorisation policy yet, Istio permits all requests without a JWT token for compatibility with legacy systems. Light Theme Dark . Shows you how to use Istio authentication policy to setup mutual TLS and basic end-user authentication. Expert Interview Series: Michael Snoyman of FP Complete. This is often used to define a JWT policy for all services bound to the gateway, instead of for individual services. For example, the following peer authentication policy requires mutual TLS on all ports, except port 80: As before, you also need a destination rule: A workload-specific peer authentication policy takes precedence over a namespace-wide policy. Policy to allow mTLS traffic for all workloads under namespace foo: For mesh level, put the policy in root-namespace according to your Istio installation. As you can see, with the valid JWT you will get an HTML response with a 200 response code.With the invalid JWT, you will get the message Your role doesnt have te required permissions with a status code 403.Lets break down what happened, First, task is a task runner (weirdly enough), this will allow us to run commands by simply specifying the task to run, the neat thing is we can set up dependencies between tasks, so by simply one command we can set up the development environment.The tasks executed by running task setup are the following ones. This in order to avoid writing this part in every microservice that I am creating. Istio enables original authentication with JSON Web Token (JWT) validation and open-source OpenID connect providers (e.g. Policy defines what authentication methods can be accepted on workload (s), and if authenticated, which method/certificate will set the request principal (i.e request.auth.principal attribute). Istiod keeps them up-to-date for each proxy, along with the keys where appropriate. DISABLE: Mutual TLS is disabled. With peerauthentication in place, the destination rule should explicitly have TLS configuration with the same mode as the corresponding peerauthentication (ISTIO_MUTUAL in this case). Istio Authentication Policy To enable Istio end-user authentication using JWT with Auth0, we add an Istio Policy authentication resource to the existing set of deployed resources. exec into auth-test container of the pod in namespace foo and run the following command: But Running the below command returns null .Why? If not set, the policy will be applied to all workloads in the same namespace as the policy. Exec into istio-proxy sidecar of the pod in namespace fookubectl exec -ti -c istio-proxy -n foo -- /bin/bash, You need to replace with whatever pod name you see when you run kubectl get pods -n foo. Istio docs mention that if mTLS is working/enabled, the proxy injects the X-Forwarded-Client-Cert header to the upstream request to the backend. If you take a look at the statsd address, it is defined with unrecognized hostname istio-statsd-prom-bridge.istio-system.istio-system:9125. PERMISSIVE (Default): Workloads accept both mutual TLS and plain text traffic. It helps you in the gradual . If you are using a version of Istio prior to 1.6 and you want to upgrade, you will have to migrate your alpha security policy objects to the beta API. Istio Archive The root cause of this is the same than Istio: Health check / sidecar fails when I enable the JWT RequestAuthentication, but after further diagnose, I have reworded to simply (trying to get help) Problem. JWT claim based routing Shows you how to use Istio authentication policy to route requests based on JWT claims. Otherwise treated as PERMISSIVE. generate new tokens to test with different issuer, audiences, expiry date, etc. The Istio agent sends the certificate received from Istiod and the private key to Envoy via the Envoy SDS API. Yeah I tried that. exit code 56 implies failed to receive network data. To configure external authorization, we need to supply a custom mesh config. Policy. settings for port 8080. First of all well take a look at how we can write an application to do custom authorization.Why?Because istios policies for JWT authorization are static, so pulling data from a database is impossible with vanilla policies. line 23 mention the service account name in the container spec. Click here to learn more. The namespace you need to specify is then istio-system.

Citadel is Istio's in-cluster Certificate Authority (CA) and is required for generating and managing cryptographic identities in the cluster. Connection can be either plaintext or mTLS tunnel. Requests to all other paths succeed, for example $INGRESS_HOST/ip. Istio 1.5 introduced a set of new objects for dealing with Authentication: PeerAuthentication and RequestAuthentication.These objects replaced the old Policy objects (removed in Istio 1.6).. The authentication policies and secure naming information is distributed to the Envoy proxies by the Pilot component. With majority of the applications architecture adopting microservice type over monolith in order to be more sensitive to need for scaling and many other, how good is the architecture in securing the interactions between the tens or hundreds of these micro-services running? This tutorial use the test token JWT test and expires in 5 seconds. That headers presence is evidence that mTLS is in use. End-user authentication and authorization Get full access to Istio in Action, Video Edition and 60K+ other titles, with free 10-day trial of O'Reilly. Istio uses Envoy Proxy as a sidecar, and delegates all the network, security, load-balancing work to Envoy. Istio is an open source project to better manage service mesh in the world of microservices. github.com. Istio can be used to enforce access control between workloads in the service mesh using the AuthorizationPolicy custom resource. Authentication Policy Shows you how to use Istio authentication policy to setup mutual TLS and basic end-user authentication. However, there should be none with hosts in the. sleep.legacy to httpbin.foo are failing (see above). The . Peer Authentication policies are used to secure service to service communication in kubernetes cluster with Istio Service Mesh by automating the process of generation, distribution and rotation of certificates and keys. Requests from legacy foo fail with exit code 56 again. In this task, you observed how the frontend service uses authentication with a JWT policy and an authorization policy. Introducing the Istio v1beta1 Authorization Policy. A tool to convert the Istio v1alpha1 authentication policy to the v1beta1 version. Lines 628 Deployment. mutual TLS authentication concepts. Run the test command again: Configure a destination rule to manage that behavior. The Mixer component handles the authorization and auditing part of Istio security. If youd like to use the same examples when trying the tasks, Figure 1. The port in destination rule is the service port(80), which maps to respective target container port(8001). Istio uses these authentication policies, along with service identities and service name checks, to establish mutual TLS connection between services. To reject requests without valid tokens, add an authorization policy with a rule specifying a DENY action for requests without request principals, shown as notRequestPrincipals: ["*"] in the following example. Introduction, motivation and design principles for the Istio v1beta1 Authorization Policy. YieldYeti Built to Maximize Results multi-strategy. PeerAuthentication defines how traffic will be tunneled (or not) to the sidecar. Since it doesn't specify a value for the selector field, the policy applies to all workloads in the mesh. Install Istio on a Kubernetes cluster with the default configuration profile, as described in Check for http responses, you should see traffic from legacy to bar/foo failing. installation steps. If you are not planning to explore any follow-on tasks, you can remove all resources simply by deleting test namespaces. Docs Blog News FAQ About. (SPIFFE Secure Production Identity Framework for Everyone). Run the following command in terminal to get the http responsesThe following command is frequently used further in this post. As expected, legacy bar fails with exit code 56. cleanup:kubectl delete peerauthentication -n bar bar-peerauthenticationkubectl delete destinationrule -n bar auth-test-dr. You can have different mTLS modes enabled on different ports. Ever wanted to know how you can use a JWT token to authenticate & authorize requests coming from an API gateway. To refine the mutual TLS settings per port, you must configure the portLevelMtls section. Run ifconfig and note the IP address and then run: Replace with 8001which is the container portand with ip address noted from running ifconfig. Istio uses Kubernetes service accounts as service identity, which offers stronger security than service name (for more details, see Istio identity).Creating service account automatically creates token. If you provide a token in the authorization header, its implicitly default location, Istio validates the token using the public key set, and rejects requests if the bearer token is invalid. That headers presence is evidence that mutual TLS is You can check the reference for more information. In peerauthentication we use container port number, not service port. While Istio automatically upgrades all traffic between the proxies and the workloads to mutual TLS between, workloads can still receive plain text traffic. The Certificate Authority(CA) maintained by Istiod then validates the credentials carried in the CSR and signs the CSR to generate the certificate which will only work with the private key that was generated with it. Authentication policy is composed of 2-part authentication: - peer: verify caller service credentials. Love podcasts or audiobooks? The authentication policy warrants that if your request contains a JWT, then it should be valid. The payload3. In this article, we dived into how istio handles authentication & authorization using JWTs, being a widely used standard, JWT pretty important to learn, istio gives us a powerful yet easy way on applying our own rules to authn & authz several types of workloads. I checked to see if the application has istio sidecar proxy, and I would assume it does because the namespace has istio-injection. Since all the traffic in and out of the pod passes through the proxy sidecar. cleanup kubectl delete peerauthentication -n istio-system default. ISTIOD (unified single binary for istios control plane)does. is specified. In Kubernetes, the format of the URI field of an X.509 certificate is: spiffe:///ns//sa/This enables Istio services to establish and accept connections with other SPIFFE-compliant systems. Run the following command to open the terminal of the containerkubectl exec -ti -c -n -- /bin/bash, and run curl http://auth-test-service.bar/test -s -o /dev/null -w "%{http_code}" -k. Service port is 80. Creating A MongoDB Replica Set Using Docker, Step-by-Step Centralized Authentication for Kubernetes with Keycloak and the Ambassador Edge Stack. For example: When the server doesnt have sidecar, the X-Forwarded-Client-Cert header is not there, which implies requests are in plain text. Authorization refers to the what: what a service or user is . Re-running the request from sleep.legacy, you should see a success return code again (200), confirming service-specific policy overrides the namespace-wide policy. From a security perspective, you shouldnt use this mode unless you provide your own security solution. NVM, I think I found why. git clone https://github.com . Istio Agent on receiving the request creates a certificate and private key and then sends a Certificate Signing Request(CSR) along with the necessary credentials to Istiod. you will find a JWT, They consist of 3 base 64 encoded parts, each separated by a dot (.)1. The Ceremony of a Microservice. A jwksUri is a resolvable URL which contains a public JWT Key Set that istio uses to validate that the token was signed by a trusted private JWT key set. Shows you how to incrementally migrate your Istio services to mutual TLS. Mutual TLS Migration Shows you how to incrementally migrate your Istio services to mutual TLS. the underlying concepts in the authentication overview. I noticed that after looking at the proxy container being restarted/crashed multiple times. upstream request to the backend. cleanup before you proceed to next section:kubectl delete peerauthentication -n foo namespace-level. This post focuses on security and to be more specific, how to secure the traffic between pods running in kubernetes cluster with Istio service mesh. STRICT: Workloads only accept mutual TLS traffic. Defines the mTLS mode used for peer authentication. For example, here is a command to check sleep.bar to httpbin.foo reachability: This one-liner command conveniently iterates through all reachability combinations: Verify there is no peer authentication policy in the system with the following command: Last but not least, verify that there are no destination rules that apply on the example services. RequestAuthentication RequestAuthentication RequestAuthentication defines what request authentication methods are supported by a workload. But why did foo legacy and bar legacy fail with http_code 503?host: *.local selects all services, including auth-test-service.legacyand Istio configures clients to use mTLS (ISTIO_MUTUAL)as we explicitly mentioned it in the destination rule that applies to all services, but the sidecar is absent in namespace legacyand thus will fail to handle it returning a 503. That headers presence is evidence that mTLS is in use. Signature, The beauty of them is that the signature is generated by an algorithm specified in the header, so that we can be sure that the token wasnt tampered with. Apart from Security, Istio offers traffic management and monitoring. Basically of all of the things that Istio does what I really need is the Authentication Policy using JWT. Using JSON Web. Mutual TLS settings for workload. From Istio 1.9, they have implemented extensibility into authorization policy by introducing a CUSTOM action, which allows you to delegate the access control decision to an external authorization . Run the command to create SA, deployment, service and to inject istio sidecar using istioctlkubectl apply -f <(istioctl kube-inject -f auth-deployment.yaml) -n foo, To verify pod is up and running:kubectl get pods -n foo -o wide, create the SA, deployment, service and use istioctl to inject istio sidecarkubectl apply -f <(istioctl kube-inject -f auth-deployment.yaml) -n bar, To verify pod is up and running:kubectl get pods -n bar -o wide, create the SA, deployment and service without sidecarkubectl create -f auth-deployment.yaml -n legacy, To verify pod is up and running:kubectl get pods -n legacy -o wide. Enough of this JWT introduction, lets get our hands dirty. You can do this by checking the host: value of Istio's Authorization Policy by itself can operate at both TCP or HTTP layers and is enforced at the envoy proxy. In istio you can configure access control to the mesh, namespace and workloads using an AuthorizationPolicy. There are different types of authentication flow which dictate how authentication is handled by the identity provider, but the most common is the Authorization Code Flow, which we . JWKS endpoint from the Istio code base. 1.5.4 2020 Istio Authors, Privacy PolicyArchived on May 21, 2020, Depending on the version of Istio, you may see destination rules for hosts other then those shown. There is configuration being messed up in my part. You can have multiple pods running in the namespace bar, but the selector field is defined to apply the policy only to those with label app: auth-test. (minikube in my case), At the time of this post, the following versions were used, Write a minimal node.js server to perform only required, Create a kubernetes deployment, service and a service account, Deploy application into three different namespaces namely foo, bar and legacy. Of course the gateway is also something important. It gives the user a very powerful and flexible, yet performant way of authorization between Kubernetes workloads. You can find more information in here. You can test this behavior if you add a policy to disable mutual TLS for the httpbin.foo workload, for example. One of the new concepts is "Mixer." The Istio Mixer, as its name suggests, can take . Who does the automated process of generation, distribution and rotation of certificates and keys? To observe this behavior, retry the request without a token, with a bad token, and with a valid token: To observe other aspects of JWT validation, use the script gen-jwt.py to In this case, were getting the Authorization: Bearer header, decoding the jwt and apply a custom validator function. Request principals are available only when valid JWT tokens are provided. Istio in 2020 - Following the Trade Winds. However, requests without tokens are accepted. Our examples use two namespaces foo and bar, with two services, httpbin and sleep, both running with an Envoy proxy. I also do not dictate how the client issues the cert or when they update it. For example, take the response from a request to httpbin/header. So we need not explicitly mention it.-k in curl command is used because, as mentioned earlier, Istio uses Kubernetes service accounts as service identity rather than service names. Why do we want request headers (line 9 res.json(req.headers))?Istio docs mention that if mTLS is working/enabled, the proxy injects the X-Forwarded-Client-Cert header to the upstream request to the backend. This post deals with only Peer Authentication. Effectively, with this configuration, the policy forward the request to the custom authorization service to decide if the request will be allowed or denied. In istio you can configure access control to the mesh, namespace and workloads using an AuthorizationPolicy. I'm completely stumped. The following scenarios will be reviewed in the article: A JWT (short for JSON Web Token) is a web standard for sharing claims between two parties. - GitHub - istio-ecosystem/security-policy-migrate: A tool to convert the Istio . Istio provides a foundation of application security that sits well with the zero-trust networking model. anything. Authorization policy supports CUSTOM, DENY and ALLOW actions for access control. If the traffic is HTTP then you should consider use some HTTP level information as it provides a lot more flexibility. This is expected because mutual TLS is now strictly required, but the workload without sidecar cannot comply. Authentication policies In here, we can see how to get headers from the request and process them. Effectively, this rule states that any JWT evaluated must have the iss field with the value my.jwt.issuer and should be signed by any key of the private part of the keys present in http://auth-service.default.svc.cluster.local/jwk/public.Just remember that this will create the policy but to apply if to the gateway we must use an AuthorizationPolicy. existing destination rules and make sure they do not match. This kind of access control is enforced at the application layer by the Envoy sidecar proxies. This peer authentication policy configures workloads to only accept requests encrypted with TLS. There are two protocols that istio support to communicate with your custom authz service: http & grpc, for both you need to supply a port, the hostname of the service and optionally in http the headers you want to pass from the request. Authentication refers to the who by providing strong identity and secure service-to-service and end-user-to-service communication. But it doesn't match. Istioldie 1.7. OIDC. For all the above cases, you can exec into istio-proxy sidecar of respective pods in respective namespaces(foo or bar) and capture traffic to check if it is encrypted/pain text or check for the x-forwarded-client-certificate in the request header. Lets now take a look at the request authentication manifest we have defined in the repo, its located in terraform/ops/main.tf. Istiod maintains a CA and generates certificates to allow secure mTLS communication in the data plane. httpbin.bar or httpbin.legacy. Istio can authenticate an incoming HTTP request, ensuring the JWT issued has not been tampered somewhere in the middle. The specification of the policy is the same as for a mesh-wide policy, but you specify the namespace it applies to under metadata. My application is in the "seldon" namespace and I tried applying my policies to the "seldon" namespace and targeting the application by its label. Pods in foo and bar accept plain text traffic from legacy, You can do this manually instead of running the above command. First of all you can see that we have an array of jwtRules in the spec, every jwtRules contains an issuer and a jwksUri. As expected legacy foo and legacy bar fail with exit code 56. When CUSTOM, DENY and ALLOW actions are used for a workload at the same time, the CUSTOM action is evaluated first, then the DENY action, and finally the ALLOW action. Corresponding destination rule should have the port with respective mTLS mode defined. Istio authentication policy enables operators to specify authentication requirements for a service (or services). For example, you might want STRICT mode on port 8001 and PERMISSIVE on some other port(must have a service exposing that port). I'm trying to configure RequestAuthentication (and AuthorizationPolicy) in an Istio mesh. cleanup:kubectl delete peerauthentication -n foo portlevel-peerauthenticationkubectl delete destinationrule -n foo auth-test-dr. A destination rule defines policies that apply to traffic intended for a service after routing has occurred and has configurations for load balancing, connection pool size from the sidecar, and outlier detection settings but we focus on the defining the tls block with necessary config for mTLS modes. used. Since legacy has no sidecar, plain text is sent which is rejected by foo/bar. https://istio.io/latest/docs/tasks/security/authentication/authn-policy/#end-user-authentication Everything works as expected until defining the AuthorizationPolicy - the moment i introduce that i would get a 502 Bad Gateway error regardless if i provide a valid JWT token or not. The request now fails with error code 403: To refine authorization with a token requirement per host, path, or method, change the authorization policy to only require JWT on /headers. These only apply when a workload selector Well learn what is Permissive mode later in this post. Run git clone https://github.com/JorgeReus/istio-jwt. Now, add a request authentication policy that requires end-user JWT for the ingress gateway. Currently nginx allows you to setup two properties for client certificate authentication: You can get the CN part with. Since the policy is namespace foo specific, legacy foo fails with code 56 (http_code 000), but legacy bar succeeds. Istio 1.15.3 is now available! host is generally specified as ..svc.cluster.localso host: *.local selects all services across all namespaces and applies mTLS in ISTIO_MUTUAL mode. (Mutual TLS), There are two types of authentication provided by Istio. The pod in legacy namespace has no envoy sidecar to encrypt traffic and inject the certificate, The following modes in peerauthentication for mTLS are supported:Source: istio docs. Find out more about By default Istio runs these Authentication policy check in permissive mode. Now send a request from foo legacy or from legacy foo.you should see plain text captured something like: Plain text is captured, why? Note that youve already created a namespace-wide policy that enables mutual TLS for all services in namespace foo and observe that requests from Meaning you can send request if you provide a valid token or provide no token at all. If there are any CUSTOM policies that match the request, evaluate and deny the request if the evaluation result is denied. As expected, request from sleep.legacy to httpbin.bar starts failing with the same reasons. When using plain http, is simpler, we only need to implement a function and apply out, After the service is deployed and ready, you can use by setting a provider in the authorization policy. Wait for a couple of minutes, and youll have a complete k8s playground with istio and all the required services & configuration applied. However, Istio cannot aggregate workload-level policies for outbound mutual TLS traffic to a service. As you see, Istio authenticates requests using that token successfully at first but rejects them after 5 seconds: You can also add a JWT policy to an ingress gateway (e.g., service istio-ingressgateway.istio-system.svc.cluster.local). When using mutual TLS, the proxy injects the X-Forwarded-Client-Cert header to the workload specific peerauthentication overrides namespace and namespace level overrides global mesh level. Policies to allow both mTLS & plaintext traffic for all workloads under namespace foo, but require mTLS for workload finance. According to the Istio security doc: "Request authentication policies can specify more than one JWT if each uses a unique location. Knowledge of Kubernetes concepts Understanding of Istio Architecture. You have a few choices for end-user authentication, such as: Applied globally, to all Services across all Namespaces via the Istio Ingress Gateway; AWS Well-Architected Framework in Serverless Part I: Security, for from in "foo" "bar" "legacy"; do for to in "foo" "bar" "legacy"; do kubectl exec "$(kubectl get pod -l app=auth-test -n ${from} -o jsonpath={.items..metadata.name})" -c auth-test -n ${from} -- curl http://auth-test-service.${to}:80/headers -s -o /dev/null -w "${from} ---> ${to}: %{http_code}\n" -k; done; done, sudo tcpdump -vvvv -A -i eth0 '((dst port and (net <, 12:38:41.228747 IP (tos 0x0, ttl 64, id 10748, offset 0, flags [DF], proto TCP (6), length 60), auth-test-deployment-55f6c8fc4b-k2blq.48996 > 192-168-219-114.auth-test-service.legacy.svc.cluster.local.8001: Flags [S], cksum 0x385a, 12:40:12.598235 IP (tos 0x0, ttl 64, id 21877, offset 0, flags [DF], proto TCP (6), length 1207), auth-test-deployment-55f6c8fc4b-k2blq.54996 > 192-168-219-74.auth-test-service.bar.svc.cluster.local.8001: Flags [P.], cksum 0x3cad (incorrect -> 0x5b80), seq 418160345:418161500, ack 2207553641, win 502, options [nop,nop,TS val 1489019456 ecr 2031669559], length 1155, By=spiffe://cluster.local/ns/bar/sa/auth-test-sa;Hash=7c60a6491f951ed8b35b75239a6b7c9f2b7671571a6e8d346adcfd5adce46db7;Subject=\\;URI=spiffe://cluster.local/ns/foo/sa/auth-test-sa, https://istio.io/latest/docs/concepts/security/, check if traffic is encrypted using tcpdump, Istiod automates key and certificate rotation at scale.
