Chapter 5. Securing an Apache ActiveMQ Broker


Apache ActiveMQ provides two layers of security: an SSL/TLS security layer, which can authenticate the broker to its clients, encrypt messages, and guarantee message integrity, and a JAAS security layer, which can authenticate clients to the broker. This chapter describes the approach you should take to enable both of these security layers, when the broker is deployed in the Red Hat JBoss A-MQ OSGi container.

5.1. Programming Client Credentials


Currently, for Java clients of Red Hat JBoss A-MQ, you must set the username/password credentials by programming. The ActiveMQConnectionFactory provides several alternative methods for specifying the username and password, as follows:
ActiveMQConnectionFactory(String userName, String password, String brokerURL);
ActiveMQConnectionFactory(String userName, String password, URI brokerURL);
Connection createConnection(String userName, String password);
QueueConnection createQueueConnection(String userName, String password);
TopicConnection createTopicConnection(String userName, String password);
Of these methods, createConnection(String userName, String password) is the most flexible, since it enables you to specify credentials on a connection-by-connection basis.

Setting login credentials for the Openwire protocol

To specify the login credentials on the client side, pass the username/password credentials as arguments to the ActiveMQConnectionFactory.createConnection() method, as shown in the following example:
// Java
public void run() {
  user = "jdoe";
  password = "secret";
  ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
 Connection connection = connectionFactory.createConnection(user, password);
