The Reliable Datagram Sockets (RDS) protocol must be disabled or not installed unless required.


Overview

V-22530 GEN007480 SV-37603r1_rule ECSC-1 Medium
Description
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.
