11.1.1. About Datasource Security

Datasource security refers to encrypting or obscuring passwords for datasource connections. These passwords can be stored in plain text in configuration files, however this represents a security risk.
The preferred solution for datasource security is the use of either security domains or password vaults. Examples of each are included below. For more information, refer to:

Example 11.1. Security Domain Example

 <security-domain name="DsRealm" cache-type="default">  
  <authentication>  
    <login-module code="ConfiguredIdentity" flag="required">  
      <module-option name="userName" value="sa"/>  
      <module-option name="principal" value="sa"/>  
      <module-option name="password" value="sa"/>  
    </login-module>  
  </authentication>  
</security-domain>
The DsRealm domain is referenced by a datasource like so: 
<datasources>
  <datasource jndi-name="java:jboss/datasources/securityDs"
    pool-name="securityDs">
    <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url>
      <driver>h2</driver>
      <new-connection-sql>select current_user()</new-connection-sql>
      <security>
        <security-domain>DsRealm</security-domain>
      </security>
    </datasource>
</datasources>

Example 11.2. Password Vault Example

<security>
  <user-name>admin</user-name>
  <password>${VAULT::ds_ExampleDS::password::N2NhZDYzOTMtNWE0OS00ZGQ0LWE4MmEtMWNlMDMyNDdmNmI2TElORV9CUkVBS3ZhdWx0}</password>
</security>
