Understanding the Default Security Configuration File

In order to understand the security configuration file, we must first understand authorities and roles.

What is an Authority?

An authority is a list of functions (system tasks). If an authority is assigned to a user, then the user can perform the authority-related functions.

Authorities are pre-defined in GigaSpaces and cannot be created or altered by the user.

Authorities are cumulative — if a user is assigned two authorities, they are able to execute all of the functions for both authorities. Below is a list of authorities that are available in GigaSpaces.


Authorities Used in Pre-configured Roles
Authority Description
MANAGE_GRID Start, terminate, restart of GSCClosed Grid Service Container. This provides an isolated runtime for one (or more) processing unit (PU) instance and exposes its state to the GSM./GSMClosed Grid Service Manager. This is is a service grid component that manages a set of Grid Service Containers (GSCs). A GSM has an API for deploying/undeploying Processing Units. When a GSM is instructed to deploy a Processing Unit, it finds an appropriate, available GSC and tells that GSC to run an instance of that Processing Unit. It then continuously monitors that Processing Unit instance to verify that it is alive, and that the SLA is not breached./LUSClosed Lookup Service. This service provides a mechanism for services to discover each other. Each service can query the lookup service for other services, and register itself in the lookup service so other services may find it.
MANAGE_PUClosed This is the unit of packaging and deployment in the GigaSpaces Data Grid, and is essentially the main GigaSpaces service. The Processing Unit (PU) itself is typically deployed onto the Service Grid. When a Processing Unit is deployed, a Processing Unit instance is the actual runtime entity. Scale up/down, scale in/out, relocate, restart PU instance, destroy PU instance
MONITOR_JVMClosed Java Virtual Machine. A virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. Monitoring of JVM statistics
MONITOR_PU Monitoring of Processing UnitsClosed This is the unit of packaging and deployment in the GigaSpaces Data Grid, and is essentially the main GigaSpaces service. The Processing Unit (PU) itself is typically deployed onto the Service Grid. When a Processing Unit is deployed, a Processing Unit instance is the actual runtime entity. (classes, connections, statistics, etc.)
PROVISION_PU Deploy, undeploy of processing units
SPACE_READ Read, Count and Notify operations
Additional Authorities
Authority Description
SPACE_WRITE Write and update operations
SPACE_TAKE Take and Clear operations
SPACE_EXECUTE Execute tasks
SPACE_ALTER Register type descriptor, Clean and Drop-Class operations
SPACE_CREATE Write only (no update) operations


What is a Role?

A role is a list of authorities. Roles can be defined for convenience, to easily assign the same list of authorities to different users. You can use the pre-configured GigaSpaces roles, and you can create your own role definitions. The pre-configured GigaSpaces roles are as follows:

Role Authorities

Creating Your Own Roles — the Security Configuration File

The default security configuration file is located at ../config/security/security-config.xml.

The relevant lines in the files are described in the following table. As you can see below, you may modify lines 14 to 19 to define your own roles.

Lines Text Notes
3-9 <beans xmlns="http://www.springframework.org/schema/beans"
xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd">
This defines the Spring security framework.
11-12 <!-- This password encoder is provided for getting started and testing purposes only and is not considered secure. --> <bean id="passwordEncoder" class="org.springframework.security.crypto.password.NoOpPasswordEncoder"/> Define the class used for password encryption. In this example, no password encryption is used.
14-19 <!-- Predefined role to privileges mapping (ROLE_VIEWER, ROLE_MNGR, ROLE_ADMIN). -->
<util:map id="roles">

Define the roles that will be used to provide users with system access. These roles are assigned to users on lines 28-39 below.

This is where you can define your own roles.

We recommend the following naming convention for user-defined roles: begin the name with ROLE_

21-25 <!-- Populates user details with authorities declared by associated role -->
<bean id="roleBasedUserService" class="com.gigaspaces.security.spring.RoleBasedUserService">
<constructor-arg ref="userService"/>
<constructor-arg ref="roles"/>
Bold text defines this as a Spring security implementation.
28-39 <sec:authentication-manager>
<sec:authentication-provider user-service-ref="roleBasedUserService"/>
<sec:password-encoder ref="passwordEncoder"/> <!-- prefer BCrypt -->
<sec:user-service id="userService">
<sec:user name="gs-admin" password="gs-admin" authorities="ROLE_ADMIN"/>
<sec:user name="gs-mngr" password="gs-mngr" authorities="ROLE_MNGR"/> <sec:user name="gs-viewer" password="gs-viewer" authorities="ROLE_VIEWER"/> </sec:user-service>

Highlighted text shows that this is an in-memory security implementation — the user information is coded here, inline.

Note that if we were accessing external security information, instead of the highlighted text, we would code an external reference, as in this example of LDAPClosed Lightweight Directory Access Protocol. An open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. security: <sec:authentication-manager> <sec:authentication-provider ref="ldapAuthenticationProvider"/> </sec:authentication-manager>
