我一直在努力了解如何保护JBoss 5.1.0.GA默认提供的JMXConnectorServerService。
目前,如果我将以下URL粘贴到JConsole中,我可以直接访问JMX而无需任何身份验证:service:jmx:rmi:/// jndi / rmi://:1290 / jmxconnector
然后我这样做是为了保护我的JMXInvoker,希望这样可以保护所有JMX访问:http://objectopia.com/2009/10/01/securing-jmx-invoker-layer-in-jboss/
但是,显然,这不适用于JMXConnectorServerService。我仍然可以通过jconsole使用上面的服务URL来访问JMX。
然后我发现了尚未适应的此功能请求:https://issues.jboss.org/browse/JBAS-8159
现在,我现在并不担心疯狂的安全措施。此URL不会暴露给外部网络。所以,我只是想看看使用“jmx-console”安全域保护jmx-remoting.sar的最简单方法是什么?
我可以切换到默认的MBean服务器,但显然,在5.1.0.GA中,这很痛苦:https://community.jboss.org/thread/153594
我真的很感激这方面的任何意见。
谢谢!

我认为服务没有得到保障,但有一个patch。
对于一个稍微简单的版本,我在这里走了一段时间,因为我没有在AS 5上测试过这个,但是我将它向后传输到AS 4并且它工作正常。
我不确定你拥有哪个版本,但我们假设它是this one。 EAP版本的版本稍微复杂一些,但前提是相同的。您需要延长JMXConnectorServerService和JMXConnectorServerServiceMBean。
在此实现中,创建服务器的代码如下所示:
// create new connector server and start it
connectorServer = JMXConnectorServerFactory.newJMXConnectorServer(url, null, mbeanServer);
在您的扩展程序中,添加以下内容:
/** The name of the JAAS domain to use for authentication */
protected String jaasDomain = null;
...
/**
* Returns the name of the JAAS domain to use for authentication
* @return the name of a JAAS Domain
*/
public String getJaasDomain() {
return jaasDomain;
}
/**
* Sets the name of the JAAS domain to use for authentication
* @param jaasDomain the JAAS Domain to use for authentication
*/
public void setJaasDomain(String jaasDomain) {
this.jaasDomain = jaasDomain;
}
现在您需要重新实现 start 方法,该方法会添加一个包含您要进行身份验证的JAAS域名的环境。
public void start() throws Exception
{
// the address to expose in the urls
String host = System.getProperty("java.rmi.server.hostname");
// check to see if registry already created
rmiRegistry = LocateRegistry.getRegistry(host, registryPort);
if (rmiRegistry != null)
{
try
{
rmiRegistry.list();
}
catch(RemoteException e)
{
log.debug("No registry running at host '" + host +
"', port '" + registryPort + "'. Will create one.");
rmiRegistry = LocateRegistry.createRegistry(registryPort, null, new DefaultSocketFactory(bindAddress));
}
}
else
{
rmiRegistry = LocateRegistry.createRegistry(registryPort, null, new DefaultSocketFactory(bindAddress));
}
String serviceURL = "service:jmx:rmi://" + host + "/jndi/rmi://" + host + ":" + registryPort + jndiPath;
JMXServiceURL url = new JMXServiceURL(serviceURL);
// create new connector server and start it
// ==== NEW AUTH CODE HERE ====
final Map<String, Object> environment = new HashMap<String, Object>();
environment.put("jmx.remote.x.login.config", jaasDomain);
connectorServer = JMXConnectorServerFactory.newJMXConnectorServer(url, environment, mbeanServer);
// ==== NEW AUTH CODE ENDS ====
connectorServer.start();
log.info("JMX Connector server: " + serviceURL);
}
您可以选择验证JAAS名称,如下所示:
/**
* Validates the name of the passed JAAS domain.
* If the name is not valid, a RuntimeException will the thrown.
* @param domain The name of the JAAS domain to validate.
*/
private void validateJaasDomain(String domain) {
try {
new LoginContext(domain);
} catch (Exception e) {
throw new RuntimeException("The JAAS Domain [" + domain + "] could not be loaded", e);
}
}
将jaasDomain属性添加到新的MBean接口:
/**
* Returns the name of the JAAS domain to use for authentication
* @return the name of a JAAS Domain
*/
public String getJaasDomain();
/**
* Sets the name of the JAAS domain to use for authentication
* @param jaasDomain the JAAS Domain to use for authentication
*/
public void setJaasDomain(String jaasDomain);
假设你的新impl是 com.vijay.JMXConnectorServerService ,新的MBean是 com.vijay.JMXConnectorServerServiceMBean ;您的部署描述符将如下所示:(使用 jmx-console jaas域,因为您可能已经安全....)
<!-- ======================================================== -->
<!-- Example Vijay JMX Remoting Service Configuration file -->
<!-- ======================================================== -->
<server>
<mbean code="com.vijay.JMXConnectorServerService"
name="jboss.remoting:service=JMXConnectorServer,protocol=rmi"
display-name="JMX Connector Server (RMI)">
<attribute name="BindAddress">
<!-- Get the port from the ServiceBindingManager -->
<value-factory bean="ServiceBindingManager" method="getStringBinding"
parameter="jboss.remoting:service=JMXConnectorServer,protocol=rmi"/>
</attribute>
<!-- if comment this out, will use 1099 as default and will conflict -->
<!-- with default JNP (JNDI) port. -->
<attribute name="RegistryPort">
<!-- Get the port from the ServiceBindingManager -->
<value-factory bean="ServiceBindingManager" method="getIntBinding"
parameter="jboss.remoting:service=JMXConnectorServer,protocol=rmi"/>
</attribute>
<!-- the path to which will be bound in rmi registry -->
<!-- the commented value below is the default. -->
<!-- <attribute name="JndiPath">/jmxconnector</attribute> -->
<attribute name="JaasDomain">jmx-console</attribute>
</mbean>
</server>
这就是我的全部。我希望它对你有用。
