Fix Recommendation

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

Check Contents

Verify the operating system disables the ability to load the "sctp" kernel module.

$ sudo grep -r sctp /etc/modprobe.d/* | grep -i "/bin/false" | grep -v "^#"
install sctp /bin/false

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.

Verify the operating system disables the ability to use SCTP with the following command:

$ sudo grep sctp /etc/modprobe.d/* | grep -i "blacklist" | grep -v "^#"
blacklist sctp

If the command does not return any output or the output is not "blacklist sctp", and use of SCTP is not documented with the ISSO as an operational requirement, this is a finding.
