| Description |
|---|
| The Reliable Datagram Sockets (RDS) protocol is a relatively new protocol developed by Oracle for communication between the nodes of a cluster. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the system to dynamically load a protocol handler by opening a socket using the protocol. |

| Ask the SA if RDS is required by application software running on the system. If so, this is not applicable. Verify the RDS protocol handler is not installed. # pkginfo | grep SUNWrds If no results are returned, this is not a finding. Verify the RDS protocol handler is prevented from dynamic loading. # grep "exclude: rds" /etc/system If no result is returned, this is a finding. |
