| The package service/network/ftp must be installed for this check. # pkg list service/network/ftp If the output of this command is: pkg list: no packages matching 'service/network/ftp' installed no further action is required. Determine if the FTP umask is set to 077. # egrep -i "^UMASK" /etc/proftpd.conf | awk '{ print $2 }' If 077 is not displayed, this is a finding. |
