Title

A separate RHEL 8 filesystem must be used for user home directories (such as /home or an equivalent). (Cat II impact)

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 that a separate file system has been created for non-privileged local interactive user home directories. Check the home directory assignment for all non-privileged 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}' /etc/passwd doej 1001 /home/doej publicj 1002 /home/publicj smithj 1003 /home/smithj The output of the command will give the directory/partition that contains the home directories for the non-privileged 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.

Fix Text

Migrate the "/home" directory onto a separate file system.
