1.1.5.4 Ensure nosuid option set on /var/log partition

Audit#

Verify that the nosuid option is set for the /var/log mount.

Run the following command to verify that the nosuid mount option is set.

Example: 

# findmnt --kernel /var/log
/var/log    /dev/sdb ext4   rw,nosuid,nodev,noexec,relatime,seclabel
IF output is produced, ensure it includes the nosuid option

Remediation#

IF the /var/log partition exists, edit the /etc/fstab file and add nosuid to the fourth field (mounting options) for the /var/log partition.

Example: 

<device> /var/log   <fstype>    defaults,rw,nosuid,nodev,noexec,relatime    0 0

Run the following command to remount /var/log with the configured options: 

# mount -o remount /var/log
