Information
OL 8 must not have the stream control transmission protocol (SCTP) kernel module installed if not required for operational support.
GROUP ID: V-248831
RULE ID: SV-248831r991589
The SCTP is a transport layer protocol, designed to support the idea of message-oriented communication, with several streams of messages within one connection. Disabling SCTP protects the system against exploitation of any flaws in its implementation.
Solution
Configure OL 8 to disable the ability to use the "sctp" kernel module.
Create a file under "/etc/modprobe.d" with the following command:
$ sudo touch /etc/modprobe.d/sctp.conf
Add the following line to the created file:
install sctp /bin/false
Configure OL 8 to disable the ability to use the sctp kernel module.
$ sudo vi /etc/modprobe.d/blacklist.conf
Add or update the line:
blacklist sctp
