GEN007480 - The Reliable Datagram Sockets (RDS) protocol must be disabled or not installed unless required - 'install rds /bin/true'

Information

The 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.

Solution

Prevent the RDS protocol handler for dynamic loading.
# echo 'install rds /bin/true' >> /etc/modprobe.conf
