Access to the Java Management Extension (JMX) administrative subsystem requires role-based access control when administrative security is enabled.
Administrative security is also referred to as global security.
A client, which can be a user or an administrative client program, can access an MBean method only if at least one of the required roles is granted to the client. WebSphere Application Server uses the declarative security approach to specify the security policy on the JMX MBean. This approach has the advantage of not requiring MBean developers to add security code. Moreover, WebSphere Application Server provides a default security policy for an MBean so in most case MBean developers do not need to specify a security policy at all. With WebSphere Application Server, you can define explicit security
policy for your MBeans if the default security policy does not meet your specific
security requirements.
