1.1.7.3 Ensure nosuid option set on /home partition

Audit

Verify that the nosuid option is set for the /home mount.

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

Example:

# findmnt --kernel /home
/home /dev/sdb ext4 rw,nosuid,nodev,relatime,seclabel

IF output is produced, ensure it includes the nosuid option

Remediation

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

Example:

<device> /home <fstype> defaults,rw,nosuid,nodev,relatime 0 0

Run the following command to remount /home with the configured options:

# mount -o remount /home
