Discussion

The use of separate file systems for different paths can protect the system from failures resulting from a file system becoming full or failing.

Check Content

Verify a separate file system has been created for nonprivileged local interactive user home directories.

Check the home directory assignment for all nonprivileged users, users with a User Identifier (UID) greater than 1000, on the system with the following command:

$ sudo awk -F: '($3>=1000)&&($7 !~ /nologin/){print $1,$3,$6,$7}' /etc/passwd
pdosadmin 1000 /home/pdosadmin /bin/bash
systemuser 1001 /home/systemuser /bin/bash
acas 1002 /home/acas /bin/bash

The output of the command will give the directory/partition that contains the home directories for the nonprivileged users on the system (in this example, "/home") and users’ shell. All accounts with a valid shell (such as /bin/bash) are considered interactive users.

Check that a file system/partition has been created for the nonprivileged interactive users with the following command:

Note: The partition of "/home" is used in the example.

$ sudo grep /home /etc/fstab

/dev/mapper/...   /home   xfs   defaults,noexec,nosuid,nodev 0 0

If a separate entry for the file system/partition containing the nonprivileged interactive user home directories does not exist, this is a finding.
