Fix Recommendation

Prevent the DCCP protocol handler for dynamic loading:

# echo "install dccp /bin/true" >> /etc/modprobe.conf.local
# echo "install dccp_ipv4 /bin/true" >> /etc/modprobe.conf.local
# echo "install dccp_ipv6 /bin/true" >> /etc/modprobe.conf.local

Check Contents

Check that the DCCP protocol handler is prevented from dynamic loading:

# grep "install dccp /bin/true" /etc/modprobe.conf /etc/modprobe.conf.local /etc/modprobe.d/*

If no result is returned, this is a finding.

# grep "install dccp_ipv4 /bin/true" /etc/modprobe.conf /etc/modprobe.conf.local /etc/modprobe.d/*

If no result is returned, this is a finding.

# grep "install dccp_ipv6" /etc/modprobe.conf /etc/modprobe.conf.local /etc/modprobe.d/* | grep ‘bin/true’

If no result is returned, this is a finding.
