Assessment Title

Rule Text

The SUSE operating system must use a separate file system for /var.

Description

Discussion Text

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

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Verify that the SUSE operating system has a separate file system/partition for "/var".

Check that a file system/partition has been created for "/var" with the following command:

# grep /var /etc/fstab
UUID=c274f65f    /var   ext4   noatime,nobarrier   1 2

If a separate entry for "/var" is not in use, this is a finding.

test_2() {
  grep -Pq '^[^# \t]+\s+/var\s+' '/etc/fstab' &>/dev/null
}

if ( test_1 && test_2 ); then
  echo "PASS"
else
  echo "FAIL"
fi

Remediation

Create a separate file system/partition on the SUSE operating system for "/var".

Migrate "/var" onto the separate file system/partition.
