Keycloak certificate authentication

The cBioPortal includes support for Keycloak authentication. This document explains why you might find Keycloak authentication useful for storing your user login information outside the cBioPortal database.

Please note that configuring your local instance to use Keycloak authentication requires a Keycloak server to be set up. This document focuses mainly on the steps to configure Keycloak for authenticating cBioPortal users. To skip to the authorization section see: authorization with Keycloak. Or continue reading to learn how to integrate Keycloak with cBioPortal. Keycloak is an open source identity and access management solution.

It has a built-in RDBM system to store login information. It can help build a security layer on top of the cBioPortal web application. Keycloak boils down to three simple terms:.

Keycloak often assigns access and permissions to specific roles rather than individual users for a fine-grained access control. Keycloak offers three types of roles:. Realm-level roles are in global namespace shared by all clients.

Client roles have basically a namespace dedicated to a client. A composite role is a role that has one or more additional roles associated with it. XML signatures and encryption are then used to verify requests from the application.

Installing

Log in to your Keycloak Identity Provider, e. Please note if you are logged in the master realm, this drop-down menu lists all the realms created. The last entry of this drop-down menu is always Add Realm. Click this to add a realm. Then type ' cbioportal ' in the name field and click the Create button. On this page, click the Create button on the right. This will bring you to the Add Client page.

Enter a Client ID for the client, e. Select saml in the Client Protocol drop 2pac mega nz box. Then click the Save button; this will take you to the client page below. Choose email as your Name ID Format. You could use this in some cases to support. Leave everything else as it is and click Save.

Make sure you add at least:. Finally, head to the Scope tab for the client and switch off Full Scope Allowedto ensure that only those roles relevant to a particular cBioPortal instance are listed in assertions sent to the instance, and not any other roles tracked in Keycloak.Server Administration.

X509 Authentication to Red Hat JBoss Fuse with Keycloak

Keycloak is a single sign on solution for web apps and RESTful web services. The goal of Keycloak is to make security simple so that it is easy for application developers to secure the apps and services they have deployed in their organization. Security features that developers normally have to write for themselves are provided out of the box and are easily tailorable to the individual requirements of your organization. Keycloak provides customizable user interfaces for login, registration, administration, and account management.

Theme support - Customize all user facing pages to integrate with your applications and branding. Login flows - optional user self-registration, recover password, verify email, require password update, etc.

Authentication flows, user federation providers, protocol mappers and many more. Keycloak is a separate server that you manage on your network.

Applications are configured to point to and be secured by this server. Applications instead are given an identity token or assertion that is cryptographically signed. These tokens can have identity information like username, address, email, and other profile data.

They can also hold permission data so that applications can make authorization decisions. These tokens can also be used to make secure invocations on REST-based services. There are some key concepts and terms you should be aware of before attempting to use Keycloak to secure your web applications and REST services. Users are entities that are able to log into your system.

They can have attributes associated with themselves like email, username, address, phone number, and birth day. They can be assigned group membership and have specific roles assigned to them. Credentials are pieces of data that Keycloak uses to verify the identity of a user. Some examples are passwords, one-time-passwords, digital certificates, or even fingerprints. Roles identify a type or category of user.

Adminusermanagerand employee are all typical roles that may exist in an organization. Applications often assign access and permissions to specific roles rather than individual users as dealing with users can be too fine grained and hard to manage. A user role mapping defines a mapping between a role and a user. A user can be associated with zero or more roles. This role mapping information can be encapsulated into tokens and assertions so that applications can decide access permissions on various resources they manage.

A composite role is a role that can be associated with other roles. For example a superuser composite role could be associated with the sales-admin and order-entry-admin roles. If a user is mapped to the superuser role they also inherit the sales-admin and order-entry-admin roles.

Groups manage groups of users. Attributes can be defined for a group. You can map roles to a group as well. Users that become members of a group inherit the attributes and role mappings that group defines. A realm manages a set of users, credentials, roles, and groups. A user belongs to and logs into a realm. Realms are isolated from one another and can only manage and authenticate the users that they control. Clients are entities that can request Keycloak to authenticate a user.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Optionally validates whether the extended key usage in the certificate matches the expected extended key usage. Once the certificate is mapped to an existing user, the behavior diverges depending on the authentication flow:. For example, the regular expression below will match the e-mail attribute:.

The ssl element contains the keystore element that defines how to load the server public key pair from a JKS keystore. Typically, the truststore contains a collection of trusted CA certificates.

Make a copy of the built-in "Browser" flow. You may want to give the new flow a distinctive name, i. Select the "Bindings" tab, find the drop down for "Browser Flow". Select the newly created X browser flow from the drop down and click on "Save". Defines whether to use the canonical format to determine a distinguished name. The format is described in detail in the official Java API documentation.

An option to use hexadecimal representation of the Serial Number. See RFC, Section Serial Number with sign bit set to 1 should be left padded with 00 octet. Serial number with decimal valueor a1 in hexadecimal representation according to RFC must be encoded as 00a1. More details can be found: RFC, appendix-B. Defines a regular expression to use as a filter to extract the certificate identity.

The regular expression must contain a single group. Defines how to match the certificate identity to an existing user.

Open Source Identity and Access Management

Username or e-mail will search for an existing user by username or e-mail. Custom Attribute Mapper will search for an existing user with a custom attribute which value matches the certificate identity.In the following scenario, we will generate a JWT token and then validate it. With your free Red Hat Developer program membership, unlock our library of cheat sheets and ebooks on next-generation application development. The next step is to create a specific client in our realm, as shown in Figure 4.

A client in Keycloak represents a resource that particular users can access, whether for authenticating a user, requesting identity information, or validating an access token.

Click Create to open the Add Client dialog box, as shown in Figure 5. Fill in all of the mandatory fields in the client form. Pay attention, especially, to Direct Grant Flow shown in Figure 6 and set its value to direct grant.

Also, change Access Type to confidential. Our authentication URL is:. A wrong username and password combination results in an HTTP response code and a response body like this:. Join Red Hat Developer and get access to handy cheat sheetsfree booksand product downloads.

A sandbox bypass vulnerability exists in Script Security Plugin 1. The kubectl cp command allows copying files between containers and the user machine. To copy files from a container, Kubernetes creates a tar inside the container, copies it over the network, and kubectl unpacks it on the user?

If the tar binary in the container is malicious, it could run any code and output unexpected, malicious results. An attacker could use this to write files to any path on the user? The untar function can both create and follow symbolic links. The issue is resolved in kubectl v1. A flaw was found in, Fedora versions of krb5 from 1. A remote unauthenticated user could use this flaw to crash the KDC.

A buffer overflow flaw was found, in versions from 2.When using group mapping, the following caveats apply regardless of which delegated authentication method is used:. When group mapping is configured, the delegated authentication source becomes the one and only place to manage group membership, and the user's groups are re-fetched with each log in.

When this feature is activated, SonarQube expects that the authentication is handled prior any query reaching the server. The tool that handles the authentication should:. Using Http header authentication is an easy way integrate your SonarQube deployment with an in-house SSO implementation. Alternately, if you're using the pull request decoration provided as part of Developer Edition and above you can harness the GitHub application needed for PR decoration to also provide authentication.

You'll need to first create a GitHub OAuth application. Click here for general instructions:. If you previously used a dedicated GitHub OAuth application for authentication, it can be removed.

On the login form, the new "Log in with GitLab" button allows users to connect with their GitLab accounts. GitLab users inherit membership to subgroups from parent groups so a user that is a member of a group will also be a member of the group's subgroups. If you're not using Keycloak, your settings are likely to be different. From SonarScanners, we recommend using local technical users for authentication against SonarQube Server.

Group Mapping Only groups not roles and static groups not dynamic groups are supported. Click here for more information. For the delegation of authorization, groups must be first defined in SonarQube. Then, the following properties must be defined to allow SonarQube to automatically synchronize the relationships between users and groups.

Authentication will be tried on each server, in the order they are listed in the configurations, until one succeeds. Such parameters can be set in sonar.In addition to the security concerns involved, you are also required to maintain account information, registration, and identity management, which most users are tired of.

This is great, but what if you have a simple static site or download server that you want to protect? Should we build a full web-application just to integrate OAuth? The easiest answer is, of course, simple. Of course it can! An authenticating reverse proxy sits in front of your site, and only allows traffic through if it has been authenticated. Combing these two technologies gives you an easy mechanism to add authentication to any web-based application.

Keycloak is an open source Identity and Access Management solution. It makes it easy to secure applications and services with little to no code. Keycloak handles user identities, user federation, identity brokering and social login. Users authenticate with Keycloak, rather than with individual services. In addition to providing the infrastructure required for Single Sign-On SSOKeycloak also provides an advanced admin UI, so you can easily manage your users without complicated CLIs or manually editing configuration files.

Through identity brokering and social login, users can login to your Keycloak service with their existing identities such as Google, Facebook, GitHub, etc…. You can even implement your own provider if you have an existing relational database, for example. In addition to user management, Keycloak can also act as an authentication endpoint. Several client adapters are also available, so integrating your existing services such as a local Jenkins instanceor a custom service such as a Java application is easy.

Finally, Keycloak supports UI theming, so you can easily roll out a highly customized authentication portal as unique as you are. The resources from these servers are returned to the client as if they originate from the Web server itself. If a client is not authenticated they can be redirected to a login page.

By structuring your system this way, you can put all your sensitive material on the internal web server, and protect everything through an authenticating reverse proxy. For even more security, the internal web server could be placed on a private Virtual Private Cloud, with absolutely no access from the outside, except through the proxy.

To integrate Keycloak and an Authenticating Reverse Proxy, we used lua-resty-openidc.

keycloak certificate authentication

OpenResty describes itself as a web platform that integrates the standard Nginx core, LuaJIT and many Lua libraries and high-quality 3rd-party Nginx modules. It is designed to help developers easily build scalable web applications, web services, and dynamic web gateways.

Build a docker container using this Dockerfile using: docker build -t authproxy. This will create a container called authproxy. You can start this proxy will an appropriate Nginx configuration. I used the following Nginx configuration file to configure lua-resty-openidc to integrate with Keycloak. You can now start your docker container, and volume mount the directory containing this configuration file.

I put it in my current directory and used the following command to start the container. Finally, I mapped port 80 on the host to port 80 in the container. Protecting a site using an authenticating reverse proxy is very easy with Keycloak.
