Securing Caches with Role-Based Authorization

What You Will Learn

How to create a cache with role-based authorization so that only users with specific roles can perform operations on it.

Prerequisites

Java 17+
An Infinispan Server running on localhost:11222 (or Docker/Podman available for Testcontainers)

Step 1: Define a Secured Cache

Create a cache configuration that restricts access to the deployer role:

<distributed-cache name="securedCache">
    <encoding media-type="application/x-protostream"/>
    <security>
        <authorization enabled="true" roles="deployer" />
    </security>
</distributed-cache>

Only users with the deployer role can read or write to this cache. Other authenticated users will get an authorization error.

Step 2: Connect and Access Caches

Connect with the default admin credentials:

   public static void connectToInfinispan() throws Exception {
      ConfigurationBuilder configurationBuilder = TutorialsConnectorHelper.connectionConfig();
      URI securedCacheConfig = InfinispanAuthorizationCache.class.getClassLoader().getResource("securedCache.xml").toURI();
      configurationBuilder.remoteCache(SECURED_CACHE).configurationURI(securedCacheConfig);

      // Connect to Infinispan with an additional cache that is secured with authorization for
      // deployer role only. We are connecting with 'admin' user that has 'admin' role.
      cacheManager = TutorialsConnectorHelper.connect(configurationBuilder);
      cache = cacheManager.getCache(TUTORIAL_CACHE_NAME);
      securedCache = cacheManager.getCache(SECURED_CACHE);
   }

Step 3: Observe Authorization in Action

Access to the unrestricted cache works normally, but accessing the secured cache without the required role throws an exception:

   static void manipulateCache() {
      // Store a value in a non secured cache
      cache.put("key", "value");

      try {
         // Store a value in a cache where your role is has not access granted
         securedCache.put("key", "value");
      } catch (HotRodClientException ex) {
         message = ex.getMessage().toLowerCase();
         System.out.println(ex.getMessage());
      }
   }

Step 4: Run the Tutorial

mvn package exec:java

You will see an authorization error message when trying to write to the secured cache, demonstrating that RBAC is enforced.
