The Reliable Datagram Sockets (RDS) protocol is a transport layer protocol designed to provide low-latency, high-bandwidth communications between cluster nodes. It was developed by the Oracle Corporation.
Options Explained:
disable - would disable the module.
disable with error logged - would disable the module and log whenever module is inserted.
enable - would enable the module.
Rationale:
If the protocol is not being used, it is recommended that kernel module not be loaded, disabling the service to reduce the potential attack surface.
Fix:
# echo install rds /bin/true >> /etc/modprobe.d/rds.conf
Parameter:
[disable/disable with error logged/enable]
Technical Mechanism:
# echo install rds /bin/true /etc/modprobe.d/rds.conf
