Verify that a separate file system/partition has been created for SUSE operating system non-privileged local interactive user home directories. Check the home directory assignment for all non-privileged users (those with a UID greater than 1000) on the system with the following command: # awk -F: '($3>=1000)&&($7 !~ /nologin/){print $1, $3, $6, $7}' /etc/passwd adamsj 1002 /home/adamsj /bin/bash jacksonm 1003 /home/jacksonm /bin/bash smithj 1001 /home/smithj /bin/bash 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 user's 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 non-privileged interactive users with the following command: Note: The partition of /home is used in the example. # grep /home /etc/fstab UUID=333ada18 /home ext4 noatime,nobarrier,nodev 1 2 If a separate entry for the file system/partition that contains the non-privileged interactive users' home directories does not exist, this is a finding.
Create a separate file system/partition for SUSE operating system non-privileged local interactive user home directories. Migrate the non-privileged local interactive user home directories onto the separate file system/partition.
