Securing the environment and restricting access to clusters is of critical importance for any deployment that stores sensitive data. This guide provides information and security best practices to help you protect Infinispan caches against network intrusion and unauthorized access.
1. Infinispan Security
Infinispan provides security for components as well as data across different layers:
-
Within the core library to provide role-based access control (RBAC) to CacheManagers, Cache instances, and stored data.
-
Over remote protocols to authenticate client requests and encrypt network traffic.
-
Across nodes in clusters to authenticate new cluster members and encrypt the cluster transport.
The Infinispan core library uses standard Java security libraries such as JAAS, JSSE, JCA, JCE, and SASL to ease integration and improve compatibility with custom applications and container environments. For this reason, the Infinispan core library provides only interfaces and a set of basic implementations.
Infinispan servers support a wide range of security standards and mechanisms to readily integrate with enterprise-level security frameworks.
2. Security authorization with role-based access control
Role-based access control (RBAC) capabilities use different permissions levels to restrict user interactions with Infinispan.
For information on creating users and configuring authorization specific to remote or embedded caches, see: |
2.1. Infinispan user roles and permissions
Infinispan includes several roles that provide users with permissions to access caches and Infinispan resources.
Role | Permissions | Description |
---|---|---|
|
ALL |

2.1.2. Role and permission mappers
Infinispan users are implemented with the javax.security.auth.Subject
class and represent a grouping of security principals of type java.security.Principal
.
Infinispan includes the PrincipalRoleMapper
API to associate security principals to roles and the RolePermissionMapper
API to associate roles with sets of permissions.
Infinispan also provides the following role and permission mapper implementations:
- Cluster role mapper
-
Stores principal to role mappings in the cluster registry.
- Cluster permission mapper
-
Stores role to permission mappings in the cluster registry and allows you to dynamically modify user roles and permissions.
- Identity role mapper
-
Uses the principal name as the role name. The type or format of the principal name depends on the source. For example in an LDAP directory the principal name could be a Distinguished Name (DN).
- Common name role mapper
-
Uses the Common Name (CN) as the role name. You can use this role mapper with an LDAP directory that contains Distinguished Names (DN); for example
cn=managers,ou=people,dc=example,dc=com
maps to themanagers
role.
2.1.3. Configuring role mappers
Infinispan enables the cluster role mapper and cluster permission mapper by default. You should configure role mappers if you want to use the identity role mapper, Common Name (CN) role mapper, or a custom implementation. For example, if your deployment integrates with an LDAP directory and you want to use the Distinguished Name (DN) as the security principal you can configure Infinispan to use the Common Name (CN) role mapper.
-
Open your Infinispan configuration for editing.
-
Declare the role mapper as part of the security authorization in the Cache Manager configuration.
-
Save the changes to your configuration.
With embedded caches you can programmatically configure role and permission mappers with the principalRoleMapper()
and rolePermissionMapper()
methods.
Role mapper configuration
<cache-container>
<security>
<authorization>
<common-name-role-mapper />
</authorization>
</security>
</cache-container>
{
"infinispan" : {
"cache-container" : {
"security" : {
"authorization" : {
"common-name-role-mapper": {}
}
}
}
}
}
infinispan:
cacheContainer:
security:
authorization:
commonNameRoleMapper: ~
2.2. Configuring caches with security authorization
Add security authorization to caches to enforce role-based access control (RBAC). This requires Infinispan users to have a role with a sufficient level of permission to perform cache operations.
-
Create Infinispan users and either grant them with roles or assign them to groups.
-
Open your Infinispan configuration for editing.
-
Add a
security
section to the configuration. -
Specify roles that users must have to perform cache operations with the
authorization
element.You can implicitly add all roles defined in the Cache Manager or explicitly define a subset of roles.
-
Save the changes to your configuration.
Implicit role configuration
The following configuration implicitly adds every role defined in the Cache Manager:
<distributed-cache>
<security>
<authorization/>
</security>
</distributed-cache>
{
"distributed-cache": {
"security": {
"authorization": {
"enabled": true
}
}
}
}
distributedCache:
security:
authorization:
enabled: true
Explicit role configuration
The following configuration explicitly adds a subset of roles defined in the Cache Manager. In this case Infinispan denies cache operations for any users that do not have one of the configured roles.
<distributed-cache>
<security>
<authorization roles="admin supervisor"/>
</security>
</distributed-cache>
{
"distributed-cache": {
"security": {
"authorization": {
"enabled": true,
"roles": ["admin","supervisor"]
}
}
}
}
distributedCache:
security:
authorization:
enabled: true
roles: ["admin","supervisor"]
3. Security realms
Security realms integrate Infinispan Server deployments with the network protocols and infrastructure in your environment that control access and verify user identities.
3.1. Creating security realms
Add security realms to Infinispan Server configuration to control access to deployments. You can add one or more security realm to your configuration.
When you add security realms to your configuration, Infinispan Server automatically enables the matching authentication mechanisms for the Hot Rod and REST endpoints. |
-
Add socket bindings to your Infinispan Server configuration as required.
-
Create keystores, or have a PEM file, to configure the security realm with TLS/SSL encryption.
Infinispan Server can also generate keystores at startup.
-
Provision the resources or services that the security realm configuration relies on.
For example, if you add a token realm, you need to provision OAuth services.
This procedure demonstrates how to configure multiple property realms.
Before you begin, you need to create properties files that add users and assign permissions with the Command Line Interface (CLI).
Use the user create
commands as follows:
user create <username> -p <changeme> -g <role> \
--users-file=application-users.properties \
--groups-file=application-groups.properties
user create <username> -p <changeme> -g <role> \
--users-file=management-users.properties \
--groups-file=management-groups.properties
Run |
Adding credentials to a properties realm with the CLI creates the user only on the server instance to which you are connected. You must manually synchronize credentials in a properties realm to each node in the cluster. |
-
Open your Infinispan Server configuration for editing.
-
Use the
security-realms
element in thesecurity
configuration to contain create multiple security realms. -
Add a security realm with the
security-realm
element and give it a unique name with thename
attribute.To follow the example, create one security realm named
application-realm
and another namedmanagement-realm
. -
Provide the TLS/SSL identify for Infinispan Server with the
server-identities
element and configure a keystore as required. -
Specify the type of security realm by adding one the following elements or fields:
-
properties-realm
-
ldap-realm
-
token-realm
-
truststore-realm
-
-
Specify properties for the type of security realm you are configuring as appropriate.
To follow the example, specify the
*.properties
files you created with the CLI using thepath
attribute on theuser-properties
andgroup-properties
elements or fields. -
If you add multiple different types of security realm to your configuration, include the
distributed-realm
element or field so that Infinispan Server uses the realms in combination with each other. -
Configure Infinispan Server endpoints to use the security realm with the with the
security-realm
attribute. -
Save the changes to your configuration.

3.2. Setting up Kerberos identities
Add Kerberos identities to a security realm in your Infinispan Server configuration to use keytab files that contain service principal names and encrypted keys, derived from Kerberos passwords.
-
Have Kerberos service account principals.
keytab files can contain both user and service account principals. However, Infinispan Server uses service account principals only which means it can provide identity to clients and allow clients to authenticate with Kerberos servers. |
In most cases, you create unique principals for the Hot Rod and REST endpoints. For example, if you have a "datagrid" server in the "INFINISPAN.ORG" domain you should create the following service principals:
-
hotrod/datagrid@INFINISPAN.ORG
identifies the Hot Rod service. -
HTTP/datagrid@INFINISPAN.ORG
identifies the REST service.
-
Create keytab files for the Hot Rod and REST services.
- Linux
-
ktutil ktutil: addent -password -p datagrid@INFINISPAN.ORG -k 1 -e aes256-cts Password for datagrid@INFINISPAN.ORG: [enter your password] ktutil: wkt http.keytab ktutil: quit
- Microsoft Windows
-
ktpass -princ HTTP/datagrid@INFINISPAN.ORG -pass * -mapuser INFINISPAN\USER_NAME ktab -k http.keytab -a HTTP/datagrid@INFINISPAN.ORG
-
Copy the keytab files to the
server/conf
directory of your Infinispan Server installation. -
Open your Infinispan Server configuration for editing.
-
Add a
server-identities
definition to the Infinispan server security realm. -
Specify the location of keytab files that provide service principals to Hot Rod and REST connectors.
-
Name the Kerberos service principals.
-
Save the changes to your configuration.

3.3. Property realms
Property realms use property files to define users and groups.
-
users.properties
contains Infinispan user credentials. Passwords can be pre-digested with theDIGEST-MD5
andDIGEST
authentication mechanisms. -
groups.properties
associates users with roles and permissions.
You can avoid authentication issues that relate to a property file by using the Infinispan CLI to enter the correct security realm name to the file.
You can find the correct security realm name of your Infinispan Server by opening the |
myuser=a_password
user2=another_password
myuser=supervisor,reader,writer
user2=supervisor

3.4. LDAP realms
LDAP realms connect to LDAP servers, such as OpenLDAP, Red Hat Directory Server, Apache Directory Server, or Microsoft Active Directory, to authenticate users and obtain membership information.
LDAP servers can have different entry layouts, depending on the type of server and deployment. It is beyond the scope of this document to provide examples for all possible configurations. |
The principal for LDAP connections must have necessary privileges to perform LDAP queries and access specific attributes. |
As an alternative to verifying user credentials with the direct-verification
attribute, you can specify an LDAP attribute that validates passwords with the user-password-mapper
element.
You cannot use endpoint authentication mechanisms that perform hashing with the Because Active Directory does not expose the |
The rdn-identifier
attribute specifies an LDAP attribute that finds the user entry based on a provided identifier, which is typically a username; for example, the uid
or sAMAccountName
attribute.
Add search-recursive="true"
to the configuration to search the directory recursively.
By default, the search for the user entry uses the (rdn_identifier={0})
filter.
Specify a different filter with the filter-name
attribute.
The `attribute-mapping` element retrieves all the groups of which the user is a member. There are typically two ways in which membership information is stored:
-
Under group entries that usually have class
groupOfNames
in themember
attribute. In this case, you can use an attribute filter as in the preceding example configuration. This filter searches for entries that match the supplied filter, which locates groups with amember
attribute equal to the user’s DN. The filter then extracts the group entry’s CN as specified byfrom
, and adds it to the user’sRoles
. -
In the user entry in the
memberOf
attribute. In this case you should use an attribute reference such as the following:<attribute-reference reference="memberOf" from="cn" to="Roles" />
This reference gets all
memberOf
attributes from the user’s entry, extracts the CN as specified byfrom
, and adds them to the user’sRoles
.

3.6. Trust store realms
Trust store realms use certificates, or certificates chains, that verify Infinispan Server and client identities when they negotiate connections.
- Keystores
-
Contain server certificates that provide a Infinispan Server identity to clients. If you configure a keystore with server certificates, Infinispan Server encrypts traffic using industry standard SSL/TLS protocols.
- Trust stores
-
Contain client certificates, or certificate chains, that clients present to Infinispan Server. Client trust stores are optional and allow Infinispan Server to perform client certificate authentication.
You must add the require-ssl-client-auth="true"
attribute to the endpoint configuration if you want Infinispan Server to validate or authenticate client certificates.

3.7. Distributed security realms
Distributed realms combine multiple different types of security realms. When users attempt to access the Hot Rod or REST endpoints, Infinispan Server uses each security realm in turn until it finds one that can perform the authentication.

4. Endpoint authentication mechanisms
Infinispan Server can use custom SASL and HTTP authentication mechanisms for Hot Rod and REST endpoints.
4.1. Infinispan Server authentication
Authentication restricts user access to endpoints as well as the Infinispan Console and Command Line Interface (CLI).
Infinispan Server includes a "default" security realm that enforces user authentication.
Default authentication uses a property realm with user credentials stored in the server/conf/users.properties
file.
Infinispan Server also enables security authorization by default so you must assign users with permissions stored in the server/conf/groups.properties
file.

4.3. Infinispan Server authentication mechanisms
Infinispan Server automatically configures endpoints with authentication mechanisms that match your security realm configuration.
For example, if you add a Kerberos security realm then Infinispan Server enables the GSSAPI
and GS2-KRB5
authentication mechanisms for the Hot Rod endpoint.
Infinispan Server enables the following SASL authentication mechanisms for Hot Rod endpoints when your configuration includes the corresponding security realm:
Security realm | SASL authentication mechanism |
---|---|
Property realms and LDAP realms |
SCRAM-*, DIGEST-*, |
Token realms |
OAUTHBEARER |
Trust realms |
EXTERNAL |
Kerberos identities |
GSSAPI, GS2-KRB5 |
SSL/TLS identities |
PLAIN |
Infinispan Server enables the following HTTP authentication mechanisms for REST endpoints when your configuration includes the corresponding security realm:
Security realm | HTTP authentication mechanism |
---|---|
Property realms and LDAP realms |
DIGEST |
Token realms |
BEARER_TOKEN |

5. Configuring TLS/SSL encryption
You can secure Infinispan Server connections using SSL/TLS encryption by configuring a keystore that contains public and private keys for Infinispan. You can also configure client certificate authentication if you require mutual TLS.
5.1. Configuring Infinispan Server keystores
Add keystores to Infinispan Server and configure it to present SSL/TLS certificates that verify its identity to clients. If a security realm contains TLS/SSL identities, it encrypts any connections to Infinispan Server endpoints that use that security realm.
-
Create a keystore that contains certificates, or certificate chains, for Infinispan Server.
Infinispan Server supports the following keystore formats: JKS, JCEKS, PKCS12/PFX and PEM. BKS, BCFKS, and UBER are also supported if the Bouncy Castle library is present.
In production environments, server certificates should be signed by a trusted Certificate Authority, either Root or Intermediate CA. |
You can use PEM files as keystores if they contain both of the following:
You should also configure PEM file keystores with an empty password ( |
-
Open your Infinispan Server configuration for editing.
-
Add the keystore that contains SSL/TLS identities for Infinispan Server to the
$ISPN_HOME/server/conf
directory. -
Add a
server-identities
definition to the Infinispan Server security realm. -
Specify the keystore file name with the
path
attribute. -
Provide the keystore password and certificate alias with the
keystore-password
andalias
attributes. -
Save the changes to your configuration.
Configure clients with a trust store so they can verify SSL/TLS identities for Infinispan Server.

5.1.2. Configuring TLS versions and cipher suites
When using SSL/TLS encryption to secure your deployment, you can configure Infinispan Server to use specific versions of the TLS protocol as well as specific cipher suites within the protocol.
-
Open your Infinispan Server configuration for editing.
-
Add the
engine
element to the SSL configuration for Infinispan Server. -
Configure Infinispan to use one or more TLS versions with the
enabled-protocols
attribute.Infinispan Server supports TLS version 1.2 and 1.3 by default. If appropriate you can set
TLSv1.3
only to restrict the security protocol for client connections. Infinispan does not recommend enablingTLSv1.1
because it is an older protocol with limited support and provides weak security. You should never enable any version of TLS older than 1.1.If you modify the SSL
engine
configuration for Infinispan Server you must explicitly configure TLS versions with theenabled-protocols
attribute. Omitting theenabled-protocols
attribute allows any TLS version.<engine enabled-protocols="TLSv1.3 TLSv1.2" />
-
Configure Infinispan to use one or more cipher suites with the
enabled-ciphersuites
attribute.You must ensure that you set a cipher suite that supports any protocol features you plan to use; for example
HTTP/2 ALPN
. -
Save the changes to your configuration.

5.2. Configuring Infinispan Server on a system with FIPS 140-2 compliant cryptography
It is possible to configure Infinispan Server to present SSL/TLS certificates that verify its identity to clients. If a security realm contains TLS/SSL identities, it encrypts any connections to Infinispan Server endpoints that use that security realm.
-
A system in FIPS mode. Execute
fips-mode-setup --check
to ensure it is enabled. -
A correctly initialized NSS database.
-
A JDK installation with the
java.security
file configured to enable theSunPKCS11
provider pointing to the NSS database and the SSL provider initialized with theSunPKCS11-nss-fips
argument. -
A certificate installed in the NSS database.
The OpenSSL provider requires a private key, but it is not possible to retrieve a private key from the PKCS11 store. FIPS does not allow the export of unencrypted keys from FIPS compliant cryptographic module. Therefore it is not possible to use the OpenSSL provider for TLS when in FIPS mode. Start the server with the |
-
Open your Infinispan Server configuration for editing.

5.3. Configuring client certificate authentication
Configure Infinispan Server to use mutual TLS to secure client connections.
You can configure Infinispan to verify client identities from certificates in a trust store in two ways:
-
Require a trust store that contains only the signing certificate, which is typically a Certificate Authority (CA). Any client that presents a certificate signed by the CA can connect to Infinispan.
-
Require a trust store that contains all client certificates in addition to the signing certificate. Only clients that present a signed certificate that is present in the trust store can connect to Infinispan.
Alternatively to providing trust stores you can use shared system certificates. |
-
Create a client trust store that contains either the CA certificate or all public certificates.
-
Create a keystore for Infinispan Server and configure an SSL/TLS identity.
PEM files can be used as trust stores provided they contain one or more certificates.
These trust stores should be configured with an empty password: |
-
Open your Infinispan Server configuration for editing.
-
Add the
require-ssl-client-auth="true"
parameter to yourendpoints
configuration. -
Add the client trust store to the
$ISPN_HOME/server/conf
directory. -
Specify the
path
andpassword
attributes for thetruststore
element in the Infinispan Server security realm configuration. -
Add the
<truststore-realm/>
element to the security realm if you want Infinispan Server to authenticate each client certificate. -
Save the changes to your configuration.
-
Set up authorization with client certificates in the Infinispan Server configuration if you control access with security roles and permissions.
-
Configure clients to negotiate SSL/TLS connections with Infinispan Server.

Using Shared System Certificates (Red Hat Enterprise Linux 7 Security Guide)
5.4. Configuring authorization with client certificates
Enabling client certificate authentication means you do not need to specify Infinispan user credentials in client configuration, which means you must associate roles with the Common Name (CN) field in the client certificate(s).
-
Provide clients with a Java keystore that contains either their public certificates or part of the certificate chain, typically a public CA certificate.
-
Configure Infinispan Server to perform client certificate authentication.
-
Open your Infinispan Server configuration for editing.
-
Enable the
common-name-role-mapper
in the security authorization configuration. -
Assign the Common Name (
CN
) from the client certificate a role with the appropriate permissions. -
Save the changes to your configuration.

6. Storing Infinispan Server credentials in keystores
External services require credentials to authenticate with Infinispan Server. To protect sensitive text strings such as passwords, add them to a credential keystore rather than directly in Infinispan Server configuration files.
You can then configure Infinispan Server to decrypt passwords for establishing connections with services such as databases or LDAP directories.
Plain-text passwords in While credential keystores are password-protected store encrypted passwords, any user account with write access to the host filesystem can tamper with the keystore itself. To completely secure Infinispan Server credentials, you should grant read-write access only to user accounts that can configure and run Infinispan Server. |
6.1. Setting up credential keystores
Create keystores that encrypt credential for Infinispan Server access.
A credential keystore contains at least one alias that is associated with an encrypted password. After you create a keystore, you specify the alias in a connection configuration such as a database connection pool. Infinispan Server then decrypts the password for that alias from the keystore when the service attempts authentication.
You can create as many credential keystores with as many aliases as required.
As a security best practice, keystores should be readable only by the user who runs the process for Infinispan Server. |
-
Open a terminal in
$ISPN_HOME
. -
Create a keystore and add credentials to it with the
credentials
command.By default, keystores are of type PKCS12. Run
help credentials
for details on changing keystore defaults.The following example shows how to create a keystore that contains an alias of "dbpassword" for the password "changeme". When you create a keystore you also specify a password to access the keystore with the
-p
argument.- Linux
-
bin/cli.sh credentials add dbpassword -c changeme -p "secret1234!"
- Microsoft Windows
-
bin\cli.bat credentials add dbpassword -c changeme -p "secret1234!"
-
Check that the alias is added to the keystore.
bin/cli.sh credentials ls -p "secret1234!" dbpassword
-
Open your Infinispan Server configuration for editing.
-
Configure Infinispan to use the credential keystore.
-
Add a
credential-stores
section to thesecurity
configuration. -
Specify the name and location of the credential keystore.
-
Specify the password to access the credential keystore with the
clear-text-credential
configuration.Instead of adding a clear-text password for the credential keystore to your Infinispan Server configuration you can use an external command or masked password for additional security.
You can also use a password in one credential store as the master password for another credential store.
-
-
Reference the credential keystore in configuration that Infinispan Server uses to connect with an external system such as a datasource or LDAP server.
-
Add a
credential-reference
section. -
Specify the name of the credential keystore with the
store
attribute. -
Specify the password alias with the
alias
attribute.Attributes in the
credential-reference
configuration are optional.-
store
is required only if you have multiple keystores. -
alias
is required only if the keystore contains multiple password aliases.
-
-
-
Save the changes to your configuration.
6.2. Securing passwords for credential keystores
Infinispan Server requires a password to access credential keystores. You can add that password to Infinispan Server configuration in clear text or, as an added layer of security, you can use an external command for the password or you can mask the password.
-
Set up a credential keystore for Infinispan Server.
Do one of the following:
-
Use the
credentials mask
command to obscure the password, for example:bin/cli.sh credentials mask -i 100 -s pepper99 "secret1234!"
Masked passwords use Password Based Encryption (PBE) and must be in the following format in your Infinispan Server configuration: <MASKED_VALUE;SALT;ITERATION>.
-
Use an external command that provides the password as standard output.
An external command can be any executable, such as a shell script or binary, that uses
java.lang.Runtime#exec(java.lang.String)
.
If the command requires parameters, provide them as a space-separated list of strings.
6.3. Credential keystore configuration
You can add credential keystores to Infinispan Server configuration and use clear-text passwords, masked passwords, or external commands that supply passwords.

7. Encrypting cluster transport
Secure cluster transport so that nodes communicate with encrypted messages. You can also configure Infinispan clusters to perform certificate authentication so that only nodes with valid identities can join.
7.1. Securing cluster transport with TLS identities
Add SSL/TLS identities to a Infinispan Server security realm and use them to secure cluster transport. Nodes in the Infinispan Server cluster then exchange SSL/TLS certificates to encrypt JGroups messages, including RELAY messages if you configure cross-site replication.
-
Install a Infinispan Server cluster.
-
Create a TLS keystore that contains a single certificate to identify Infinispan Server.
You can also use a PEM file if it contains a private key in PKCS#1 or PKCS#8 format, a certificate, and has an empty password:
password=""
.If the certificate in the keystore is not signed by a public certificate authority (CA) then you must also create a trust store that contains either the signing certificate or the public key.
-
Add the keystore to the
$ISPN_HOME/server/conf
directory. -
Add the keystore to a new security realm in your Infinispan Server configuration.
You should create dedicated keystores and security realms so that Infinispan Server endpoints do not use the same security realm as cluster transport.
<server xmlns="urn:infinispan:server:14.0"> <security> <security-realms> <security-realm name="cluster-transport"> <server-identities> <ssl> <!-- Adds a keystore that contains a certificate that provides SSL/TLS identity to encrypt cluster transport. --> <keystore path="server.pfx" relative-to="infinispan.server.config.path" password="secret" alias="server"/> </ssl> </server-identities> </security-realm> </security-realms> </security> </server>
-
Configure cluster transport to use the security realm by specifying the name of the security realm with the
server:security-realm
attribute.<infinispan> <cache-container> <transport server:security-realm="cluster-transport"/> </cache-container> </infinispan>
When you start Infinispan Server, the following log message indicates that the cluster is using the security realm for cluster transport:
[org.infinispan.SERVER] ISPN080060: SSL Transport using realm <security_realm_name>
7.2. JGroups encryption protocols
To secure cluster traffic, you can configure Infinispan nodes to encrypt JGroups message payloads with secret keys.
Infinispan nodes can obtain secret keys from either:
-
The coordinator node (asymmetric encryption).
-
A shared keystore (symmetric encryption).
You configure asymmetric encryption by adding the ASYM_ENCRYPT
protocol to a JGroups stack in your Infinispan configuration.
This allows Infinispan clusters to generate and distribute secret keys.
When using asymmetric encryption, you should also provide keystores so that nodes can perform certificate authentication and securely exchange secret keys. This protects your cluster from man-in-the-middle (MitM) attacks. |
Asymmetric encryption secures cluster traffic as follows:
-
The first node in the Infinispan cluster, the coordinator node, generates a secret key.
-
A joining node performs certificate authentication with the coordinator to mutually verify identity.
-
The joining node requests the secret key from the coordinator node. That request includes the public key for the joining node.
-
The coordinator node encrypts the secret key with the public key and returns it to the joining node.
-
The joining node decrypts and installs the secret key.
-
The node joins the cluster, encrypting and decrypting messages with the secret key.
You configure symmetric encryption by adding the SYM_ENCRYPT
protocol to a JGroups stack in your Infinispan configuration.
This allows Infinispan clusters to obtain secret keys from keystores that you provide.
-
Nodes install the secret key from a keystore on the Infinispan classpath at startup.
-
Node join clusters, encrypting and decrypting messages with the secret key.
ASYM_ENCRYPT
with certificate authentication provides an additional layer of encryption in comparison with SYM_ENCRYPT
.
You provide keystores that encrypt the requests to coordinator nodes for the secret key.
Infinispan automatically generates that secret key and handles cluster traffic, while letting you specify when to generate secret keys.
For example, you can configure clusters to generate new secret keys when nodes leave.
This ensures that nodes cannot bypass certificate authentication and join with old keys.
SYM_ENCRYPT
, on the other hand, is faster than ASYM_ENCRYPT
because nodes do not need to exchange keys with the cluster coordinator.
A potential drawback to SYM_ENCRYPT
is that there is no configuration to automatically generate new secret keys when cluster membership changes.
Users are responsible for generating and distributing the secret keys that nodes use to encrypt cluster traffic.
7.3. Securing cluster transport with asymmetric encryption
Configure Infinispan clusters to generate and distribute secret keys that encrypt JGroups messages.
-
Create a keystore with certificate chains that enables Infinispan to verify node identity.
-
Place the keystore on the classpath for each node in the cluster.
For Infinispan Server, you put the keystore in the $ISPN_HOME directory.
-
Add the
SSL_KEY_EXCHANGE
andASYM_ENCRYPT
protocols to a JGroups stack in your Infinispan configuration, as in the following example:<infinispan> <jgroups> <!-- Creates a secure JGroups stack named "encrypt-tcp" that extends the default TCP stack. --> <stack name="encrypt-tcp" extends="tcp"> <!-- Adds a keystore that nodes use to perform certificate authentication. --> <!-- Uses the stack.combine and stack.position attributes to insert SSL_KEY_EXCHANGE into the default TCP stack after VERIFY_SUSPECT2. --> <SSL_KEY_EXCHANGE keystore_name="mykeystore.jks" keystore_password="changeit" stack.combine="INSERT_AFTER" stack.position="VERIFY_SUSPECT2"/> <!-- Configures ASYM_ENCRYPT --> <!-- Uses the stack.combine and stack.position attributes to insert ASYM_ENCRYPT into the default TCP stack before pbcast.NAKACK2. --> <!-- The use_external_key_exchange = "true" attribute configures nodes to use the `SSL_KEY_EXCHANGE` protocol for certificate authentication. --> <ASYM_ENCRYPT asym_keylength="2048" asym_algorithm="RSA" change_key_on_coord_leave = "false" change_key_on_leave = "false" use_external_key_exchange = "true" stack.combine="INSERT_BEFORE" stack.position="pbcast.NAKACK2"/> </stack> </jgroups> <cache-container name="default" statistics="true"> <!-- Configures the cluster to use the JGroups stack. --> <transport cluster="${infinispan.cluster.name}" stack="encrypt-tcp" node-name="${infinispan.node.name:}"/> </cache-container> </infinispan>
When you start your Infinispan cluster, the following log message indicates that the cluster is using the secure JGroups stack:
[org.infinispan.CLUSTER] ISPN000078: Starting JGroups channel cluster with stack <encrypted_stack_name>
Infinispan nodes can join the cluster only if they use ASYM_ENCRYPT
and can obtain the secret key from the coordinator node.
Otherwise the following message is written to Infinispan logs:
[org.jgroups.protocols.ASYM_ENCRYPT] <hostname>: received message without encrypt header from <hostname>; dropping it
7.4. Securing cluster transport with symmetric encryption
Configure Infinispan clusters to encrypt JGroups messages with secret keys from keystores that you provide.
-
Create a keystore that contains a secret key.
-
Place the keystore on the classpath for each node in the cluster.
For Infinispan Server, you put the keystore in the $ISPN_HOME directory.
-
Add the
SYM_ENCRYPT
protocol to a JGroups stack in your Infinispan configuration.
<infinispan>
<jgroups>
<!-- Creates a secure JGroups stack named "encrypt-tcp" that extends the default TCP stack. -->
<stack name="encrypt-tcp" extends="tcp">
<!-- Adds a keystore from which nodes obtain secret keys. -->
<!-- Uses the stack.combine and stack.position attributes to insert SYM_ENCRYPT into the default TCP stack after VERIFY_SUSPECT2. -->
<SYM_ENCRYPT keystore_name="myKeystore.p12"
keystore_type="PKCS12"
store_password="changeit"
key_password="changeit"
alias="myKey"
stack.combine="INSERT_AFTER"
stack.position="VERIFY_SUSPECT2"/>
</stack>
</jgroups>
<cache-container name="default" statistics="true">
<!-- Configures the cluster to use the JGroups stack. -->
<transport cluster="${infinispan.cluster.name}"
stack="encrypt-tcp"
node-name="${infinispan.node.name:}"/>
</cache-container>
</infinispan>
When you start your Infinispan cluster, the following log message indicates that the cluster is using the secure JGroups stack:
[org.infinispan.CLUSTER] ISPN000078: Starting JGroups channel cluster with stack <encrypted_stack_name>
Infinispan nodes can join the cluster only if they use SYM_ENCRYPT
and can obtain the secret key from the shared keystore.
Otherwise the following message is written to Infinispan logs:
[org.jgroups.protocols.SYM_ENCRYPT] <hostname>: received message without encrypt header from <hostname>; dropping it
8. Infinispan ports and protocols
As Infinispan distributes data across your network and can establish connections for external client requests, you should be aware of the ports and protocols that Infinispan uses to handle network traffic.
If run Infinispan as a remote server then you might need to allow remote clients through your firewall. Likewise, you should adjust ports that Infinispan nodes use for cluster communication to prevent conflicts or network issues.
8.1. Infinispan Server ports and protocols
Infinispan Server provides network endpoints that allow client access with different protocols.
Port | Protocol | Description |
---|---|---|
|
TCP |
Hot Rod and REST |
|
TCP |
Memcached (disabled by default) |
Single port
Infinispan Server exposes multiple protocols through a single TCP port, 11222
.
Handling multiple protocols with a single port simplifies configuration and reduces management complexity when deploying Infinispan clusters.
Using a single port also enhances security by minimizing the attack surface on the network.
Infinispan Server handles HTTP/1.1, HTTP/2, and Hot Rod protocol requests from clients via the single port in different ways.
Client requests can include the HTTP/1.1 upgrade
header field to initiate
HTTP/1.1 connections with Infinispan Server.
Client applications can then send the Upgrade: protocol
header field, where protocol
is a server endpoint.
Client requests include Server Name Indication (SNI) mappings for Infinispan Server endpoints to negotiate protocols over a TLS connection.
Applications must use a TLS library that supports the ALPN extension. Infinispan uses WildFly OpenSSL bindings for Java. |
Client requests that include Hot Rod headers automatically route to Hot Rod endpoints.
8.1.1. Configuring network firewalls for Infinispan traffic
Adjust firewall rules to allow traffic between Infinispan Server and client applications.
On Red Hat Enterprise Linux (RHEL) workstations, for example, you can allow
traffic to port 11222
with firewalld as follows:
# firewall-cmd --add-port=11222/tcp --permanent
success
# firewall-cmd --list-ports | grep 11222
11222/tcp
To configure firewall rules that apply across a network, you can use the nftables utility.
8.2. TCP and UDP ports for cluster traffic
Infinispan uses the following ports for cluster transport messages:
Default Port | Protocol | Description |
---|---|---|
|
TCP/UDP |
JGroups cluster bind port |
|
UDP |
JGroups multicast |
Cross-site replication
Infinispan uses the following ports for the JGroups RELAY2 protocol:
7900
-
For Infinispan clusters running on Kubernetes.
7800
-
If using UDP for traffic between nodes and TCP for traffic between clusters.
7801
-
If using TCP for traffic between nodes and TCP for traffic between clusters.
