| 2 | # |
| 3 | # Description |
| 4 | # =========== |
| 5 | # The Reliable Datagram Sockets (RDS) protocol is a transport layer protocol |
| 6 | # designed to provide low-latency, high-bandwidth communications between |
| 7 | # cluster nodes. It was developed by the Oracle Corporation. |
| 8 | # |
| 9 | # Rationale |
| 10 | # ========= |
| 11 | # If the protocol is not being used, it is recommended that kernel module |
| 12 | # not be loaded, disabling the service to reduce the potential attack surface. |
| 13 | # |
| 14 | # Audit |
| 15 | # ===== |
| 16 | # Run the following commands and verify the output is as indicated: |
| 17 | # |
| 18 | # # modprobe -n -v rds |
| 19 | # install /bin/true |
| 20 | # # lsmod | grep rds |
| 21 | # <No output> |
| 22 | # |
| 23 | # Remediation |
| 24 | # =========== |
| 25 | # Edit or create the file /etc/modprobe.d/CIS.conf and add the following line: |
| 26 | # |
| 27 | # install rds /bin/true |
| 28 | # |
