CIS Ubuntu Linux 16.04 LTS Benchmark v2.0.0 - Control 3.4.3
Description
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.
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.
Impact
None.
Audit Procedure
Command Line
Run the following commands and verify the output is as indicated:
modprobe -n -v rds
lsmod | grep rds
Expected Result
install /bin/true
The lsmod command should return no output.
Remediation
Command Line
Edit or create a file in the /etc/modprobe.d/ directory ending in .conf
Example: vi /etc/modprobe.d/rds.conf
and add the following line:
install rds /bin/true
Default Value
RDS module is available but typically not loaded by default.
