    Is IP Multicast Secured?

      I am running a jboss eap 4.3.0 cluster with 3 nodes.

      The communication between 3 nodes is based on JGroups protocol by using UDP/IP Multicast.

      I am curious security mechanism about the Multicast address,e.g. by default in cluster-service.xml udpGroup:228.1.2.3:45567

      It seems that anyone could use this address and try to join the Multicast Group. Can some "bad guy" in the network easily write a program or directly run another jboss server to listen on this Multicast address/port and fetch the packet(information)??? If yes, how to secure it?

      Thank you.
