Check Text ( C-36733r1_chk )
Check for the existence of the /etc/hosts.allow and /etc/hosts.deny files (normally located within the /etc directory). # find /etc -type f -name hosts.allow -o -name hosts.deny \| xargs -n1 ls -lL If either file does not exist, this is a finding. Check for the presence of a deny by default entry. cat /hosts.deny \| tr '\011' ' ' \| tr -s ' ' \| sed -e 's/^[ \t]*//' \|grep -v "^#" \| egrep "ALL: ALL" If the ALL: ALL entry is not present the hosts.deny file, any TCP service from a host or network not matching other rules will be allowed access. If the entry is not in hosts.deny, this is a finding.

Check for the existence of the /etc/hosts.allow and /etc/hosts.deny files (normally located within the /etc directory).
# find /etc -type f -name hosts.allow -o -name hosts.deny | xargs -n1 ls -lL

If either file does not exist, this is a finding.

Check for the presence of a deny by default entry.
cat /hosts.deny | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' |grep -v "^#" | egrep "ALL: ALL"
