Fix Recommendation

Configure OL 9 to prevent the sctp kernel module from being loaded.

Add the following line to the file /etc/modprobe.d/sctp.conf (or create sctp.conf if it does not exist):

install sctp /bin/false
blacklist sctp

Check Contents

Verify OL 9 disables the ability to load the sctp kernel module with the following command:

$ grep -irs sctp /etc/modprobe.conf /etc/modprobe.d/*
/etc/modprobe.d/sctp.conf:install sctp /bin/false
/etc/modprobe.d/sctp.conf:blacklist sctp

If the command does not return any output, or the line is commented out, and use of sctp is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
