Ensure only / permits device files.
Опис
The filesystem mount option nodev ensures that special device files are not recognized as device files. This recommendation audits all rootvg filesystems to ensure that only the root filesystem '/' allows the use of device special files. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
Како се проверава
Метод провере: Команда љуске
command -v lsfs >/dev/null 2>&1 || exit 1; out=$( { lsfs | grep jfs | egrep -v "/dev/hd4|nodev"; mount | grep jfs | egrep -v "/dev/hd4|nodev" ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20- Очекивани излаз
compliant
Како се исправља
Метод исправке: Смерница или закрпа инфраструктуре
The following command remounts filesystems with 'nodev' added: mount | grep jfs | /usr/bin/egrep -v "/dev/hd4|nodev" | while read lv fs jfs m d t options do mount -o remount,${options},nodev $fs done The following command updates the stanza in /etc/filesystems lsfs | grep jfs | /usr/bin/egrep -v "/dev/hd4|nodev" | while read lv node fs jfs size options rest do if [ ${options} == "--" ]; then chfs -a options=nodev $fs else chfs -a options=${options},nodev $fs fi done
