# Chapter 27. Red Hat JBoss Data Grid Security: Authorization and Authentication

## 27.1. Red Hat JBoss Data Grid Security: Authorization and Authentication

Red Hat JBoss Data Grid is able to perform authorization on CacheManagers and Caches. JBoss Data Grid authorization is built on standard security features available in a JDK, such as JAAS and the SecurityManager.

If an application attempts to interact with a secured CacheManager and Cache, it must provide an identity which JBoss Data Grid’s security layer can validate against a set of required roles and permissions. Once validated, the client is issued a token for subsequent operations. Where access is denied, an exception indicating a security violation is thrown.

When a cache has been configured for with authorization, retrieving it returns an instance of SecureCache. SecureCache is a simple wrapper around a cache, which checks whether the "current user" has the permissions required to perform an operation. The "current user" is a Subject associated with the AccessControlContext.

JBoss Data Grid maps Principals names to roles, which in turn, represent one or more permissions. The following diagram represents these relationships:

## 27.2. Permissions

Access to a CacheManager or a Cache is controlled using a set of required permissions. Permissions control the type of action that is performed on the CacheManager or Cache, rather than the type of data being manipulated. Some of these permissions can apply to specifically name entities, such as a named cache. Different types of permissions are available depending on the entity.

A convenience permission which includes all of the above.

ALL_WRITE

Combines WRITE and BULK_WRITE.

Note

Some permissions may need to be combined with others in order to be useful. For example, EXEC with READ or with WRITE.

## 27.3. Role Mapping

In order to convert the Principals in a Subject into a set of roles used for authorization, a PrincipalRoleMapper must be specified in the global configuration. Red Hat JBoss Data Grid ships with three mappers, and also allows you to provide a custom mapper.

Table 27.3. Mappers

Mapper NameJavaXMLDescription

IdentityRoleMapper

org.infinispan.security.impl.IdentityRoleMapper

<identity-role-mapper />

Uses the Principal name as the role name.

CommonNameRoleMapper

org.infinispan.security.impl.CommonRoleMapper

<common-name-role-mapper />

If the Principal name is a Distinguished Name (DN), this mapper extracts the Common Name (CN) and uses it as a role name. For example the DN cn=managers,ou=people,dc=example,dc=com will be mapped to the role managers.

ClusterRoleMapper

org.infinispan.security.impl.ClusterRoleMapper

<cluster-role-mapper />

Uses the ClusterRegistry to store principal to role mappings. This allows the use of the CLI’s GRANT and DENY commands to add/remove roles to a Principal.

Custom Role Mapper

<custom-role-mapper class="a.b.c" />

Supply the fully-qualified class name of an implementation of org.infinispan.security.impl.PrincipalRoleMapper

## 27.4. Configuring Authentication and Role Mapping using Login Modules

When using the authentication login-module for querying roles from LDAP, you must implement your own mapping of Principals to Roles, as custom classes are in use. An example implementation of this conversion is found in the JBoss Data Grid Developer Guide , while a declarative configuration example is below:

Example of LDAP Login Module Configuration

 <security-domain name="ispn-secure" cache-type="default">
<authentication>
<module-option name="java.naming.factory.initial" value="com.sun.jndi.ldap.LdapCtxFactory"/>
<module-option name="java.naming.provider.url" value="ldap://localhost:389"/>
<module-option name="java.naming.security.authentication" value="simple"/>
<module-option name="principalDNPrefix" value="uid="/>
<module-option name="principalDNSuffix" value=",ou=People,dc=infinispan,dc=org"/>
<module-option name="rolesCtxDN" value="ou=Roles,dc=infinispan,dc=org"/>
<module-option name="uidAttributeID" value="member"/>
<module-option name="matchOnUserDN" value="true"/>
<module-option name="roleAttributeID" value="cn"/>
<module-option name="roleAttributeIsDN" value="false"/>
<module-option name="searchScope" value="ONELEVEL_SCOPE"/>
</authentication>
</security-domain>

Example of Login Module Configuration

<security-domain name="krb-admin" cache-type="default">
<authentication>
<module-option name="useKeyTab" value="true"/>
<module-option name="keyTab" value="${basedir}/keytab/admin.keytab"/> </login-module> </authentication> </security-domain> When using GSSAPI authentication, this would typically involve using LDAP for role mapping, with the JBoss Data Grid server authenticating itself to the LDAP server via GSSAPI. For an example on configuring this authentication to an Active Directory server refer to Active Directory Authentication Using Kerberos (GSSAPI). Important For information on configuring an LDAP server, or specifying users and roles in an LDAP server, refer to the Red Hat Directory Server Administration Guide . ## 27.5. Configuring Red Hat JBoss Data Grid for Authorization Authorization is configured at two levels: the cache container (CacheManager), and at the single cache. CacheManager The following is an example configuration for authorization at the CacheManager level: CacheManager Authorization (Declarative Configuration) <cache-container name="local" default-cache="default"> <security> <authorization> <identity-role-mapper /> <role name="admin" permissions="ALL"/> <role name="reader" permissions="READ"/> <role name="writer" permissions="WRITE"/> <role name="supervisor" permissions="ALL_READ ALL_WRITE"/> </authorization> </security> </cache-container> Each cache container determines: • whether to use authorization. • a class which will map principals to a set of roles. • a set of named roles and the permissions they represent. You can choose to use only a subset of the roles defined at the container level. Roles Roles may be applied on a cache-per-cache basis, using the roles defined at the cache-container level, as follows: Defining Roles <local-cache name="secured"> <security> <authorization roles="admin reader writer supervisor"/> </security> </local-cache> Important Any cache that is intended to require authentication must have a listing of roles defined; otherwise authentication is not enforced as the no-anonymous policy is defined by the cache’s authorization. Important The REST protocol is not supported for use with authorization, and any attempts to access a cache with authorization enabled will result in a SecurityException. ## 27.6. Authorization Using a SecurityManager In Red Hat JBoss Data Grid’s Remote Client-Server mode, authorization is able to work without a SecurityManager for basic cache operations. In Library mode, a SecurityManager may also be used to perform some of the more complex tasks, such as distexec and query among others. In order to enforce access restrictions, enable the SecurityManager in your JVM using one of the following methods: Command Line java -Djava.security.manager ... Programmaticaly System.setSecurityManager(new SecurityManager()); Using the JDK’s default implementation is not required; however, an appropriate policy file must be supplied. The policy file defines a set of permissions, which the SecurityManager examines when an application performs an action. If the action is allowed by the policy file, then the SecurityManager will permit the action to take place; however, if the action is not allowed by the policy then the SecurityManager denies that action. Example policy files are below: Library Mode Security Policy File Example // Grant permissions to all of the Infinispan libraries.

## 27.7. SecurityManager in Java

### 27.7.1. About the Java Security Manager

Java Security Manager

The Java Security Manager is a class that manages the external boundary of the Java Virtual Machine (JVM) sandbox, controlling how code executing within the JVM can interact with resources outside the JVM. When the Java Security Manager is activated, the Java API checks with the security manager for approval before executing a wide range of potentially unsafe operations.

The Java Security Manager uses a security policy to determine whether a given action will be permitted or denied.

### 27.7.2. About Java Security Manager Policies

Security Policy

A set of defined permissions for different classes of code. The Java Security Manager compares actions requested by applications against the security policy. If an action is allowed by the policy, the Security Manager will permit that action to take place. If the action is not allowed by the policy, the Security Manager will deny that action. The security policy can define permissions based on the location of code, on the code’s signature, or based on the subject’s principals.

The Java Security Manager and the security policy used are configured using the Java Virtual Machine options java.security.manager and java.security.policy.

Basic Information

A security policy’s entry consists of the following configuration elements, which are connected to the policytool:

CodeBase
The URL location (excluding the host and domain information) where the code originates from. This parameter is optional.
SignedBy
The alias used in the keystore to reference the signer whose private key was used to sign the code. This can be a single value or a comma-separated list of values. This parameter is optional. If omitted, presence or lack of a signature has no impact on the Java Security Manager.
Principals
A list of principal_type/principal_name pairs, which must be present within the executing thread’s principal set. The Principals entry is optional. If it is omitted, it signifies that the principals of the executing thread will have no impact on the Java Security Manager.
Permissions
A permission is the access which is granted to the code. Many permissions are provided as part of the Java Enterprise Edition 6 (Java EE 6) specification. This document only covers additional permissions which are provided by JBoss EAP 6.
Important

Refer to your container documentation on how to configure the security policy, as it may differ depending on the implementation.

### 27.7.3. Write a Java Security Manager Policy

Introduction

An application called policytool is included with most JDK and JRE distributions, for the purpose of creating and editing Java Security Manager security policies. Detailed information about policytool is linked from http://docs.oracle.com/javase/6/docs/technotes/tools/.

Setup a new Java Security Manager Policy

1. Start policytool

Start the policytool tool in one of the following ways.

1. Red Hat Enterprise Linux

From your GUI or a command prompt, run /usr/bin/policytool.

2. Microsoft Windows Server

Run policytool.exe from your Start menu or from the bin\ of your Java installation. The location can vary.

2. Create a policy.

To create a policy, select Add Policy Entry. Add the parameters you need, then click Done. .

3. Edit an existing policy.

Select the policy from the list of existing policies, and select the Edit Policy Entry button. Edit the parameters as needed.

4. Delete an existing policy.

Select the policy from the list of existing policies, and select the Remove Policy Entry button.

### 27.7.4. Run Red Hat JBoss Data Grid Server Within the Java Security Manager

To specify a Java Security Manager policy, you need to edit the Java options passed to the server instance during the bootstrap process. For this reason, you cannot pass the parameters as options to the standalone.sh script. The following procedure guides you through the steps of configuring your instance to run within a Java Security Manager policy.

Prerequisites

Before you following this procedure, you need to write a security policy, using the policytool command which is included with your Java Development Kit (JDK). This procedure assumes that your policy is located at JDG_HOME/bin/server.policy . As an alternative, write the security policy using any text editor and manually save it as JDG_HOME/bin/server.policy * The JBoss Data Grid server must be completely stopped before you edit any configuration files.

Perform the following procedure for each physical host or instance in your environment.

Configure the Security Manager for JBoss Data Grid Server

1. Open the configuration file.

Open the configuration file for editing. This location of this file is listed below by OS. Note that this is not the executable file used to start the server, but a configuration file that contains runtime parameters. For Linux: JDG_HOME/bin/standalone.conf For Windows: JDG_HOME\bin\standalone.conf.bat

2. Add the Java options to the file.

To ensure the Java options are used, add them to the code block that begins with:

if [ "x$JAVA_OPTS" = "x" ]; then You can modify the -Djava.security.policy value to specify the exact location of your security policy. It should go onto one line only, with no line break. Using == when setting the -Djava.security.policy property specifies that the security manager will use only the specified policy file. Using = specifies that the security manager will use the specified policy combined with the policy set in the policy.url section of JAVA_HOME/lib/security/java.security . Important JBoss Enterprise Application Platform releases from 6.2.2 onwards require that the system property jboss.modules.policy-permissions is set to true. standalone.conf JAVA_OPTS="$JAVA_OPTS -Djava.security.manager -Djava.security.policy==$PWD/server.policy -Djboss.home.dir=$JBOSS_HOME -Djboss.modules.policy-permissions=true"

standalone.conf.bat

set "JAVA_OPTS=%JAVA_OPTS% -Djava.security.manager -Djava.security.policy==\path\to\server.policy -Djboss.home.dir=%JBOSS_HOME% -Djboss.modules.policy-permissions=true"

3. Start the server.

Start the server as normal.

## 27.8. Data Security for Remote Client Server Mode

### 27.8.1. About Security Realms

A security realm is a series of mappings between users and passwords, and users and roles. Security realms are a mechanism for adding authentication and authorization to your EJB and Web applications. Red Hat JBoss Data Grid Server provides two security realms by default:

• ManagementRealm stores authentication information for the Management API, which provides the functionality for the Management CLI and web-based Management Console. It provides an authentication system for managing JBoss Data Grid Server itself. You could also use the ManagementRealm if your application needed to authenticate with the same business rules you use for the Management API.
• ApplicationRealm stores user, password, and role information for Web Applications and EJBs.

Each realm is stored in two files on the filesystem:

• REALM-users.properties stores usernames and hashed passwords.
• REALM-roles.properties stores user-to-role mappings.
• mgmt-groups.properties stores user-to-role mapping file for ManagementRealm.

The properties files are stored in the standalone/configuration/ directories. The files are written simultaneously by the add-user.sh or add-user.bat command. When you run the command, the first decision you make is which realm to add your new user to.

### 27.8.2. Add a New Security Realm

1. Run the Management CLI

Start the cli.sh or cli.bat command and connect to the server.

2. Create the new security realm itself

Run the following command to create a new security realm named MyDomainRealm on a domain controller or a standalone server.

/host=master/core-service=management/security-realm=MyDomainRealm:add()
3. Create the reference to the properties file which will store information about the new realm’s users

Run the below command to define the location of the new security realm’s properties file; this file contains information regarding the users of this security realm. The following command references a file named myfile.properties in the jboss.server.config.dir.

Note

The newly-created properties file is not managed by the included add-user.sh and add-user.bat scripts. It must be managed externally.

/host=master/core-service=management/security-realm=MyDomainRealm/authentication=properties:add(path="myfile.properties",relative-to="jboss.server.config.dir")
4. Reload the server

Reload the server so the changes will take effect.

:reload

Result

The new security realm is created. When you add users and roles to this new realm, the information will be stored in a separate file from the default security realms. You can manage this new file using your own applications or procedures.

### 27.8.3. Add a User to a Security Realm

1. Run the add-user.sh or add-user.bat command

Open a terminal and change directories to the JDG_HOME/bin/ directory. If you run Red Hat Enterprise Linux or another UNIX-like operating system, run add-user.sh. If you run Microsoft Windows Server, run add-user.bat.

2. Choose whether to add a Management User or Application User

For this procedure, type b to add an Application User.

3. Choose the realm this user will be added to

By default, the only available realms are the ManagementRealm and ApplicationRealm; however, if a custom realm has been added, then its name may be entered instead.

4. Type the username, password, and roles, when prompted

Type the desired username, password, and optional roles when prompted. Verify your choice by typing yes, or type no to cancel the changes. The changes are written to each of the properties files for the security realm.

### 27.8.4. Configuring Security Realms Declaratively

In Remote Client-Server mode, a Hot Rod endpoint must specify a security realm.

The security realm declares an authentication and an authorization section.

Configuring Security Realms Declaratively

<security-realms>
<security-realm name="ManagementRealm">
<authentication>
<local default-user="$local" skip-group-loading="true"/> <properties path="mgmt-users.properties" relative-to="jboss.server.config.dir"/> </authentication> <authorization map-groups-to-roles="false"> <properties path="mgmt-groups.properties" relative-to="jboss.server.config.dir"/> </authorization> </security-realm> <security-realm name="ApplicationRealm"> <authentication> <local default-user="$local" allowed-users="*" skip-group-loading="true"/>
<properties path="application-users.properties" relative-to="jboss.server.config.dir"/>
</authentication>
<authorization>
<properties path="application-roles.properties" relative-to="jboss.server.config.dir"/>
</authorization>
</security-realm>
</security-realms>

The server-identities parameter can also be used to specify certificates.

### 27.8.5. Loading Roles from LDAP for Authorization (Remote Client-Server Mode)

An LDAP directory contains entries for user accounts and groups, cross referenced by attributes. Depending on the LDAP server configuration, a user entity may map the groups the user belongs to through memberOf attributes; a group entity may map which users belong to it through uniqueMember attributes; or both mappings may be maintained by the LDAP server.

Users generally authenticate against the server using a simple user name. When searching for group membership information, depending on the directory server in use, searches could be performed using this simple name or using the distinguished name of the user’s entry in the directory.

The authentication step of a user connecting to the server always happens first. Once the user is successfully authenticated the server loads the user’s groups. The authentication step and the authorization step each require a connection to the LDAP server. The realm optimizes this process by reusing the authentication connection for the group loading step. As will be shown within the configuration steps below it is possible to define rules within the authorization section to convert a user’s simple user name to their distinguished name. The result of a "user name to distinguished name mapping" search during authentication is cached and reused during the authorization query when the force attribute is set to "false". When force is true, the search is performed again during authorization (while loading groups). This is typically done when different servers perform authentication and authorization.

<authorization>
<ldap connection="...">
<!-- OPTIONAL -->
<!-- Only one of the following. -->
<username-filter base-dn="..." recursive="..." user-dn-attribute="..." attribute="..." />
<advanced-filter base-dn="..." recursive="..." user-dn-attribute="..." filter="..." />

<group-search group-name="..." iterative="..." group-dn-attribute="..." group-name-attribute="..." >
<!-- One of the following -->
<group-to-principal base-dn="..." recursive="..." search-by="...">
<membership-filter principal-attribute="..." />
</group-to-principal>
<principal-to-group group-attribute="..." />
</group-search>
</ldap>
</authorization>
Important

These examples specify some attributes with their default values. This is done for demonstration. Attributes that specify their default values are removed from the configuration when it is persisted by the server. The exception is the force attribute. It is required, even when set to the default value of false.

The username-to-dn element specifies how to map the user name to the distinguished name of their entry in the LDAP directory. This element is only required when both of the following are true:

• The authentication and authorization steps are against different LDAP servers.
• The group search uses the distinguished name.

This specifies that the user name entered by the remote user is the user’s distinguished name.
<username-to-dn force="false">
</username-to-dn>

+ This defines a 1:1 mapping and there is no additional configuration.

The next option is very similar to the simple option described above for the authentication step. A specified attribute is searched for a match against the supplied user name.
<username-to-dn force="true">
<username-filter base-dn="dc=people,dc=harold,dc=example,dc=com" recursive="false" attribute="sn" user-dn-attribute="dn" />
</username-to-dn>

+ The attributes that can be set here are:

• base-dn: The distinguished name of the context to begin the search.
• recursive: Whether the search will extend to sub contexts. Defaults to false.
• attribute: The attribute of the users entry to try and match against the supplied user name. Defaults to uid.
• user-dn-attribute: The attribute to read to obtain the users distinguished name. Defaults to dn.

The final option is to specify an advanced filter, as in the authentication section this is an opportunity to use a custom filter to locate the users distinguished name.
<username-to-dn force="true">
<advanced-filter base-dn="dc=people,dc=harold,dc=example,dc=com" recursive="false" filter="sAMAccountName={0}" user-dn-attribute="dn" />
</username-to-dn>

+ For the attributes that match those in the username-filter example, the meaning and default values are the same. There is one new attribute:

• filter: Custom filter used to search for a user’s entry where the user name will be substituted in the {0} place holder.

Important

The XML must remain valid after the filter is defined so if any special characters are used such as & ensure the proper form is used. For example & for the & character.

There are two different styles that can be used when searching for group membership information. The first style is where the user’s entry contains an attribute that references the groups the user is a member of. The second style is where the group contains an attribute referencing the users entry.

When there is a choice of which style to use Red Hat recommends that the configuration for a user’s entry referencing the group is used. This is because with this method group information can be loaded by reading attributes of known distinguished names without having to perform any searches. The other approach requires extensive searches to identify the groups that reference the user.

Before describing the configuration here are some LDIF examples to illustrate this.

Principal to Group - LDIF example.

This example illustrates where we have a user TestUserOne who is a member of GroupOne, GroupOne is in turn a member of GroupFive. The group membership is shown by the use of a memberOf attribute which is set to the distinguished name of the group of which the user (or group) is a member.

It is not shown here but a user could potentially have multiple memberOf attributes set, one for each group of which the user is directly a member.

dn: uid=TestUserOne,ou=users,dc=principal-to-group,dc=example,dc=org
objectClass: extensibleObject
objectClass: top
objectClass: groupMember
objectClass: inetOrgPerson

memberOf: uid=GroupOne,ou=groups,dc=principal-to-group,dc=example,dc=org
memberOf: uid=Slashy/Group,ou=groups,dc=principal-to-group,dc=example,dc=org

dn: uid=GroupOne,ou=groups,dc=principal-to-group,dc=example,dc=org

objectClass: groupMember
objectClass: group
objectClass: uidObject
uid: GroupFive
distinguishedName: uid=GroupFive,ou=subgroups,ou=groups,dc=principal-to-group,dc=example,dc=org

Group to Principal - LDIF Example

This example shows the same user TestUserOne who is a member of GroupOne which is in turn a member of GroupFive - however in this case it is an attribute uniqueMember from the group to the user being used for the cross reference.

Again the attribute used for the group membership cross reference can be repeated, if you look at GroupFive there is also a reference to another user TestUserFive which is not shown here.

dn: uid=TestUserOne,ou=users,dc=group-to-principal,dc=example,dc=org
objectClass: top
objectClass: inetOrgPerson
objectClass: uidObject
objectClass: person
objectClass: organizationalPerson
cn: Test User One
sn: Test User One
uid: TestUserOne

dn: uid=GroupOne,ou=groups,dc=group-to-principal,dc=example,dc=org
objectClass: top
objectClass: groupOfUniqueNames
objectClass: uidObject
cn: Group One
uid: GroupOne
uniqueMember: uid=TestUserOne,ou=users,dc=group-to-principal,dc=example,dc=org

dn: uid=GroupFive,ou=subgroups,ou=groups,dc=group-to-principal,dc=example,dc=org
objectClass: top
objectClass: groupOfUniqueNames
objectClass: uidObject
cn: Group Five
uid: GroupFive
uniqueMember: uid=TestUserFive,ou=users,dc=group-to-principal,dc=example,dc=org
uniqueMember: uid=GroupOne,ou=groups,dc=group-to-principal,dc=example,dc=org
##### General Group Searching

Before looking at the examples for the two approaches shown above we first need to define the attributes common to both of these.

<group-search group-name="..." iterative="..." group-dn-attribute="..." group-name-attribute="..." >
...
</group-search>
• group-name: This attribute is used to specify the form that should be used for the group name returned as the list of groups of which the user is a member. This can either be the simple form of the group name or the group’s distinguished name. If the distinguished name is required this attribute can be set to DISTINGUISHED_NAME. Defaults to SIMPLE.
• iterative: This attribute is used to indicate if, after identifying the groups a user is a member of, we should also iteratively search based on the groups to identify which groups the groups are a member of. If iterative searching is enabled we keep going until either we reach a group that is not a member if any other groups or a cycle is detected. Defaults to false.

Cyclic group membership is not a problem. A record of each search is kept to prevent groups that have already been searched from being searched again.

Important

For iterative searching to work the group entries need to look the same as user entries. The same approach used to identify the groups a user is a member of is then used to identify the groups of which the group is a member. This would not be possible if for group to group membership the name of the attribute used for the cross reference changes or if the direction of the reference changes.

• group-dn-attribute: On an entry for a group which attribute is its distinguished name. Defaults to dn.
• group-name-attribute: On an entry for a group which attribute is its simple name. Defaults to uid.

Principal to Group Example Configuration

Based on the example LDIF from above here is an example configuration iteratively loading a user’s groups where the attribute used to cross reference is the memberOf attribute on the user.

<authorization>
<ldap connection="LocalLdap">
<username-filter base-dn="ou=users,dc=principal-to-group,dc=example,dc=org" recursive="false" attribute="uid" user-dn-attribute="dn" />
<group-search group-name="SIMPLE" iterative="true" group-dn-attribute="dn" group-name-attribute="uid">
<principal-to-group group-attribute="memberOf" />
</group-search>
</ldap>
</authorization>

The most important aspect of this configuration is that the principal-to-group element has been added with a single attribute.

• group-attribute: The name of the attribute on the user entry that matches the distinguished name of the group the user is a member of. Defaults to memberOf.

Group to Principal Example Configuration

This example shows an iterative search for the group to principal LDIF example shown above.

<authorization>
<ldap connection="LocalLdap">
<username-filter base-dn="ou=users,dc=group-to-principal,dc=example,dc=org" recursive="false" attribute="uid" user-dn-attribute="dn" />
<group-search group-name="SIMPLE" iterative="true" group-dn-attribute="dn" group-name-attribute="uid">
<group-to-principal base-dn="ou=groups,dc=group-to-principal,dc=example,dc=org" recursive="true" search-by="DISTINGUISHED_NAME">
<membership-filter principal-attribute="uniqueMember" />
</group-to-principal>
</group-search>
</ldap>
</authorization>

Here an element group-to-principal is added. This element is used to define how searches for groups that reference the user entry will be performed. The following attributes are set:

• base-dn: The distinguished name of the context to use to begin the search.
• recursive: Whether sub-contexts also be searched. Defaults to false.
• search-by: The form of the role name used in searches. Valid values are SIMPLE and DISTINGUISHED_NAME. Defaults to DISTINGUISHED_NAME.

Within the group-to-principal element there is a membership-filter element to define the cross reference.

• principal-attribute: The name of the attribute on the group entry that references the user entry. Defaults to member.

## 27.9. Securing Interfaces

### 27.9.1. Hot Rod Interface Security

#### 27.9.1.1. Publish Hot Rod Endpoints as a Public Interface

Red Hat JBoss Data Grid’s Hot Rod server operates as a management interface as a default. To extend its operations to a public interface, alter the value of the interface parameter in the socket-binding element from management to public as follows:

<socket-binding name="hotrod" interface="public" port="11222" />

#### 27.9.1.2. Encryption of communication between Hot Rod Server and Hot Rod client

Hot Rod can be encrypted using TLS/SSL, and has the option to require certificate-based client authentication.

Use the following procedure to secure the Hot Rod connector using SSL.

Secure Hot Rod Using SSL/TLS

1. Generate a Keystore

Create a Java Keystore using the keytool application distributed with the JDK and add your certificate to it. The certificate can be either self signed, or obtained from a trusted CA depending on your security policy.

2. Place the Keystore in the Configuration Directory

Put the keystore in the ~/JDG_HOME/standalone/configuration directory with the standalone-hotrod-ssl.xml file from the ~/JDG_HOME/docs/examples/configs directory.

3. Declare an SSL Server Identify

Declare an SSL server identity within a security realm in the management section of the configuration file. The SSL server identity must specify the path to a keystore and its secret key.

<server-identities>
<ssl protocol="...">
<keystore path="..." relative-to="..." keystore-password="${VAULT::VAULT_BLOCK::ATTRIBUTE_NAME::ENCRYPTED_VALUE}" /> </ssl> <secret value="..." /> </server-identities> See Configure Hot Rod Authentication (X.509) for details about these parameters. 4. Add the Security Element Add the security element to the Hot Rod connector as follows: <hotrod-connector socket-binding="hotrod" cache-container="local"> <encryption security-realm="ApplicationRealm" require-ssl-client-auth="false" /> </hotrod-connector> 5. Optionally Configure Client Certificate Authentication If you require the server to authenticate the client certificate, create a truststore that contains the valid client certificates and set the require-ssl-client-auth attribute to true. 6. Start the Server Start the server using the following: bin/standalone.sh -c standalone-hotrod-ssl.xml  This will start a server with a Hot Rod endpoint on port 11222. This endpoint will only accept SSL connections. Important To prevent plain text passwords from appearing in configurations or source codes, plain text passwords should be changed to Vault passwords. For more information about how to set up Vault passwords, see the Password Vault section of the JBoss Enterprise Application Platform security documentation. . #### 27.9.1.3. Securing Hot Rod to LDAP Server using SSL When connecting to an LDAP server with SSL enabled it may be necessary to specify a trust store or key store containing the appropriate certificates. Encryption of communication between Hot Rod Server and Hot Rod client describes how to set up SSL for Hot Rod client-server communication. This can be used, for example, for secure Hot Rod client authentication with PLAIN username/password. When the username/password is checked against credentials in LDAP, a secure connection from the Hot Rod server to the LDAP server is also required. To enable connection from the Hot Rod server to LDAP via SSL, a security realm must be defined as follows: Hot Rod Client Authentication to LDAP Server <management> <security-realms> <security-realm name="LdapSSLRealm"> <authentication> <truststore path="ldap.truststore" relative-to="jboss.server.config.dir" keystore-password=${VAULT::VAULT_BLOCK::ATTRIBUTE_NAME::ENCRYPTED_VALUE} />
</authentication>
</security-realm>
</security-realms>
<outbound-connections>
<ldap name="LocalLdap" url="ldaps://localhost:10389" search-dn="uid=wildfly,dc=simple,dc=wildfly,dc=org" search-credential="secret" security-realm="LdapSSLRealm" />
</outbound-connections>
</management>

Important

To prevent plain text passwords from appearing in configurations or source codes, plain text passwords should be changed to Vault passwords. For more information about how to set up Vault passwords, see the Red Hat Enterprise Application Platform Security Guide .

#### 27.9.1.4. User Authentication over Hot Rod Using SASL

##### 27.9.1.4.1. User Authentication over Hot Rod Using SASL

User authentication over Hot Rod can be implemented using the following Simple Authentication and Security Layer (SASL) mechanisms:

• PLAIN is the least secure mechanism because credentials are transported in plain text format. However, it is also the simplest mechanism to implement. This mechanism can be used in conjunction with encryption (SSL) for additional security.
• DIGEST-MD5 is a mechanism than hashes the credentials before transporting them. As a result, it is more secure than the PLAIN mechanism.
• GSSAPI is a mechanism that uses Kerberos tickets. As a result, it requires a correctly configured Kerberos Domain Controller (for example, Microsoft Active Directory).
• EXTERNAL is a mechanism that obtains the required credentials from the underlying transport (for example, from a X.509 client certificate) and therefore requires client certificate encryption to work correctly.
##### 27.9.1.4.2. Configure Hot Rod Authentication (GSSAPI/Kerberos)

Use the following steps to set up Hot Rod Authentication using the SASL GSSAPI/Kerberos mechanism:

Configure SASL GSSAPI/Kerberos Authentication - Server-side Configuration

1. Define a Kerberos security login module using the security domain subsystem:

<system-properties>
<property name="java.security.krb5.conf" value="/tmp/infinispan/krb5.conf"/>
<property name="java.security.krb5.debug" value="true"/>
<property name="jboss.security.disable.secdomain.option" value="true"/>
</system-properties>

<security-domain name="infinispan-server" cache-type="default">
<authentication>
<module-option name="debug" value="true"/>
<module-option name="storeKey" value="true"/>
<module-option name="refreshKrb5Config" value="true"/>
<module-option name="useKeyTab" value="true"/>
<module-option name="doNotPrompt" value="true"/>
<module-option name="keyTab" value="/tmp/infinispan/infinispan.keytab"/>
<module-option name="principal" value="HOTROD/localhost@INFINISPAN.ORG"/>
</authentication>
</security-domain>
2. Ensure that the cache-container has authorization roles defined, and these roles are applied in the cache’s authorization block as seen in Configuring Red Hat JBoss Data Grid for Authorization.
3. Configure a Hot Rod connector as follows:

<hotrod-connector socket-binding="hotrod"
cache-container="default">
<authentication security-realm="ApplicationRealm">
<sasl server-name="node0"
mechanisms="{mechanism_name}"
qop="{qop_name}"
strength="{value}">
<policy>
<no-anonymous value="true" />
</policy>
<property name="com.sun.security.sasl.digest.utf8">true</property>
</sasl>
</authentication>
</hotrod-connector>
• The server-name attribute specifies the name that the server declares to incoming clients. The client configuration must also contain the same server name value.
• The server-context-name attribute specifies the name of the login context used to retrieve a server subject for certain SASL mechanisms (for example, GSSAPI).
• The mechanisms attribute specifies the authentication mechanism in use. See User Authentication over Hot Rod Using SASL for a list of supported mechanisms.
• The qop attribute specifies the SASL quality of protection value for the configuration. Supported values for this attribute are auth (authentication), auth-int (authentication and integrity, meaning that messages are verified against checksums to detect tampering), and auth-conf (authentication, integrity, and confidentiality, meaning that messages are also encrypted). Multiple values can be specified, for example, auth-int auth-conf. The ordering implies preference, so the first value which matches both the client and server’s preference is chosen.
• The strength attribute specifies the SASL cipher strength. Valid values are low, medium, and high.
• The no-anonymous element within the policy element specifies whether mechanisms that accept anonymous login are permitted. Set this value to false to permit and true to deny.
4. Perform the Client-Side configuration on each client. As the Hot Rod client is configured programmatically information on this configuration is found in the JBoss Data Grid Developer Guide .
##### 27.9.1.4.3. Configure Hot Rod Authentication (MD5)

Use the following steps to set up Hot Rod Authentication using the SASL MD5 mechanism:

Configure Hot Rod Authentication (MD5)

1. Set up the Hot Rod Connector configuration by adding the sasl element to the authentication element (for details on the authentication element, see Configuring Security Realms Declaratively) as follows:

<hotrod-connector socket-binding="hotrod"
cache-container="default">
<authentication security-realm="ApplicationRealm">
<sasl server-name="myhotrodserver"
mechanisms="DIGEST-MD5"
qop="auth" />
</authentication>
</hotrod-connector>
• The server-name attribute specifies the name that the server declares to incoming clients. The client configuration must also contain the same server name value.
• The mechanisms attribute specifies the authentication mechanism in use. See User Authentication over Hot Rod Using SASL for a list of supported mechanisms.
• The qop attribute specifies the SASL quality of production value for the configuration. Supported values for this attribute are auth, auth-int, and auth-conf.
2. Configure each client to be connected to the Hot Rod connector. As this step is performed programmatically instructions are found in JBoss Data Grid’s Developer Guide .
##### 27.9.1.4.4. Configure Hot Rod Using LDAP/Active Directory

Use the following to configure authentication over Hot Rod using LDAP or Microsoft Active Directory:

<security-realms>
<security-realm name="ApplicationRealm">
<authentication>
<ldap connection="ldap_connection"
recursive="true"
base-dn="cn=users,dc=infinispan,dc=org">
</ldap>
</authentication>
</security-realm>
</security-realms>
<outbound-connections>
<ldap name="ldap_connection"
url="ldap://my_ldap_server"
search-dn="CN=test,CN=Users,DC=infinispan,DC=org"
</outbound-connections>

The following are some details about the elements and parameters used in this configuration:

• The security-realm element’s name parameter specifies the security realm to reference to use when establishing the connection.
• The authentication element contains the authentication details.
• The ldap element specifies how LDAP searches are used to authenticate a user. First, a connection to LDAP is established and a search is conducted using the supplied user name to identify the distinguished name of the user. A subsequent connection to the server is established using the password supplied by the user. If the second connection succeeds, the authentication is a success.

• The connection parameter specifies the name of the connection to use to connect to LDAP.
• The (optional) recursive parameter specifies whether the filter is executed recursively. The default value for this parameter is false.
• The base-dn parameter specifies the distinguished name of the context to use to begin the search from.
• The (optional) user-dn parameter specifies which attribute to read for the user’s distinguished name after the user is located. The default value for this parameter is dn.
• The outbound-connections element specifies the name of the connection used to connect to the LDAP directory.
• The ldap element specifies the properties of the outgoing LDAP connection.

• The name parameter specifies the unique name used to reference this connection.
• The url parameter specifies the URL used to establish the LDAP connection.
• The search-dn parameter specifies the distinguished name of the user to authenticate and to perform the searches.
• The search-credential parameter specifies the password required to connect to LDAP as the search-dn.
• The (optional) initial-context-factory parameter allows the overriding of the initial context factory. the default value of this parameter is com.sun.jndi.ldap.LdapCtxFactory.
##### 27.9.1.4.5. Configure Hot Rod Authentication (X.509)

The X.509 certificate can be installed at the node, and be made available to other nodes for authentication purposes for inbound and outbound SSL connections. This is enabled using the <server-identities/> element of a security realm definition, which defines how a server appears to external applications. This element can be used to configure a password to be used when establishing a remote connection, as well as the loading of an X.509 key.

The following example shows how to install an X.509 certificate on the node.

<security-realm name="ApplicationRealm">
<server-identities>
<ssl protocol="...">
<keystore path="..." relative-to="..." keystore-password="..." alias="..." key-password="..." />
</ssl>
</server-identities>

[... authentication/authorization ...]

</security-realms>

In the provided example, the SSL element contains the <keystore/> element, which is used to define how to load the key from the file-based keystore. The following parameters ave available for this element.

Table 27.4. <server-identities/> Options

ParameterMandatory/OptionalDescription

path

Mandatory

This is the path to the keystore, this can be an absolute path or relative to the next attribute.

relative-to

Optional

The name of a service representing a path the keystore is relative to.

keystore-password

Mandatory

The password required to open the keystore.

alias

Optional

The alias of the entry to use from the keystore - for a keystore with multiple entries in practice the first usable entry is used but this should not be relied on and the alias should be set to guarantee which entry is used.

key-password

Optional

The password to load the key entry, if omitted the keystore-password will be used instead.

Note

If the following error occurs, specify a key-password as well as an alias to ensure only one key is loaded.

UnrecoverableKeyException: Cannot recover key

### 27.9.2. REST Interface Security

#### 27.9.2.1. Publish REST Endpoints as a Public Interface

Red Hat JBoss Data Grid’s REST server operates as a management interface by default. To extend its operations to a public interface, alter the value of the interface parameter in the socket-binding element from management to public as follows:

<socket-binding name="http"
interface="public"
port="8080"/>

#### 27.9.2.2. Enable Security for the REST Endpoint

Use the following procedure to enable security for the REST endpoint in Red Hat JBoss Data Grid.

Note

The REST endpoint supports any of the JBoss Enterprise Application Platform security subsystem providers.

Enable Security for the REST Endpoint

To enable security for JBoss Data Grid when using the REST interface, make the following changes to standalone.xml:

1. Ensure that the rest endpoint defines a valid configuration for the authentication attribute. An example configuration is below:

<subsystem xmlns="urn:infinispan:server:endpoint:8.1">
<rest-connector socket-binding="rest" cache-container="security">
<authentication security-realm="ApplicationRealm" auth-method="BASIC"/>
</rest-connector>
</subsystem>
2. Check Security Domain Declaration

Ensure that the security subsystem contains the corresponding security-domain declaration. For details about setting up security-domain declarations, see the JBoss Enterprise Application Platform 7 documentation.

3. Add an Application User

Run the relevant script and enter the configuration settings to add an application user.

1. Run the adduser.sh script (located in $JDG_HOME/bin ). 1. On a Windows system, run the adduser.bat file (located in$JDG_HOME/bin ) instead.
2. When prompted about the type of user to add, select Application User (application-users.properties) by entering b.
3. Accept the default value for realm (ApplicationRealm) by pressing the return key.
5. When prompted for a group, enter REST.
6. Ensure the username and application realm information is correct when prompted and enter "yes" to continue.
4. Verify the Created Application User

Ensure that the created application user is correctly configured.

1. Check the configuration listed in the application-users.properties file (located in $JDG_HOME/standalone/configuration/ ). The following is an example of what the correct configuration looks like in this file: user1=2dc3eacfed8cf95a4a31159167b936fc 2. Check the configuration listed in the application-roles.properties file (located in$JDG_HOME/standalone/configuration/ ). The following is an example of what the correct configuration looks like in this file:

user1=REST
5. Test the Server

Start the server and enter the following link in a browser window to access the REST endpoint:

http://localhost:8080/rest/namedCache
Note

If testing using a GET request, a 405 response code is expected and indicates that the server was successfully authenticated.

### 27.9.3. Memcached Interface Security

#### 27.9.3.1. Publish Memcached Endpoints as a Public Interface

Red Hat JBoss Data Grid’s memcached server operates as a management interface by default. It is possible to extend the memcached operations to a public interface, but there is no additional security available for this interface. If security is a concern then it is recommended to keep this interface on an isolated, internal network, or to use either the REST or Hot Rod interfaces.

To configure the memcached interface as a public interface, alter the value of the interface parameter in the socket-binding element from management to public as follows:

<socket-binding name="memcached"
interface="public"
port="11211" />

## 27.10. Active Directory Authentication (Non-Kerberos)

See Example of LDAP Login Module Configuration for a non-Kerberos Active Directory Authentication configuration example.

## 27.11. Active Directory Authentication Using Kerberos (GSSAPI)

When using Red Hat JBoss Data Grid with Microsoft Active Directory, data security can be enabled via Kerberos authentication. To configure Kerberos authentication for Microsoft Active Directory, use the following procedure.

Configure Kerberos Authentication for Active Directory (Library Mode)

1. Configure JBoss EAP server to authenticate itself to Kerberos. This can be done by configuring a dedicated security domain, for example:

<security-domain name="ldap-service" cache-type="default">
<authentication>
<module-option name="storeKey" value="true"/>
<module-option name="useKeyTab" value="true"/>
<module-option name="refreshKrb5Config" value="true"/>
<module-option name="principal" value="ldap/localhost@INFINISPAN.ORG"/>
<module-option name="keyTab" value="${basedir}/keytab/ldap.keytab"/> <module-option name="doNotPrompt" value="true"/> </login-module> </authentication> </security-domain> 2. The security domain for authentication must be configured correctly for JBoss EAP, an application must have a valid Kerberos ticket. To initiate the Kerberos ticket, you must reference another security domain using <module-option name="usernamePasswordDomain" value="krb-admin"/> This points to the standard Kerberos login module described in Step 3. <security-domain name="ispn-admin" cache-type="default"> <authentication> <login-module code="SPNEGO" flag="requisite"> <module-option name="password-stacking" value="useFirstPass"/> <module-option name="serverSecurityDomain" value="ldap-service"/> <module-option name="usernamePasswordDomain" value="krb-admin"/> </login-module> <login-module code="AdvancedAdLdap" flag="required"> <module-option name="password-stacking" value="useFirstPass"/> <module-option name="bindAuthentication" value="GSSAPI"/> <module-option name="jaasSecurityDomain" value="ldap-service"/> <module-option name="java.naming.provider.url" value="ldap://localhost:389"/> <module-option name="baseCtxDN" value="ou=People,dc=infinispan,dc=org"/> <module-option name="baseFilter" value="(krb5PrincipalName={0})"/> <module-option name="rolesCtxDN" value="ou=Roles,dc=infinispan,dc=org"/> <module-option name="roleFilter" value="(member={1})"/> <module-option name="roleAttributeID" value="cn"/> </login-module> </authentication> </security-domain> 3. The security domain authentication configuration described in the previous step points to the following standard Kerberos login module: <security-domain name="krb-admin" cache-type="default"> <authentication> <login-module code="Kerberos" flag="required"> <module-option name="useKeyTab" value="true"/> <module-option name="principal" value="admin@INFINISPAN.ORG"/> <module-option name="keyTab" value="${basedir}/keytab/admin.keytab"/>
</authentication>
</security-domain>

## 27.12. The Security Audit Logger

### 27.12.1. The Security Audit Logger

Red Hat JBoss Data Grid includes a logger to audit security logs for the cache, specifically whether a cache or a cache manager operation was allowed or denied for various operations.

The default audit logger is org.infinispan.security.impl.DefaultAuditLogger. This logger outputs audit logs using the available logging framework (for example, JBoss Logging) and provides results at the TRACE level and the AUDIT category.

To send the AUDIT category to either a log file, a JMS queue, or a database, use the appropriate log appender.

### 27.12.2. Configure the Security Audit Logger (Library Mode)

Use the following to configure the audit logger in Red Hat JBoss Data Grid:

<infinispan>
...
<global-security>
<authorization audit-logger = "org.infinispan.security.impl.DefaultAuditLogger">
...
</authorization>
</global-security>
...
</infinispan>

### 27.12.3. Configure the Security Audit Logger (Remote Client-Server Mode)

Use the following code to configure the audit logger in Red Hat JBoss Data Grid Remote Client-Server Mode.

To use a different audit logger, specify it in the authorization element. The authorization element must be within the cache-container element in the Infinispan subsystem (in the standalone.xml configuration file).

<cache-container name="local" default-cache="default">
<security>
<authorization audit-logger="org.infinispan.security.impl.DefaultAuditLogger">
<identity-role-mapper/>
<role name="writer" permissions="WRITE"/>
<role name="supervisor" permissions="ALL_READ ALL_WRITE"/>
</authorization>
</security>
<local-cache name="default">
<locking isolation="NONE" acquire-timeout="30000" concurrency-level="1000" striping="false"/>
<transaction mode="NONE"/>
<security>
</cache-container>
The default audit logger for server mode is org.jboss.as.clustering.infinispan.subsystem.ServerAuditLogger which sends the log messages to the server audit log. See the Management Interface Audit Logging chapter in the JBoss Enterprise Application Platform Administration and Configuration Guide for more information.
Users can implement custom audit loggers in Red Hat JBoss Data Grid Library and Remote Client-Server Mode. The custom logger must implement the org.infinispan.security.AuditLogger interface. If no custom logger is provided, the default logger (DefaultAuditLogger) is used.
