Verify that a separate file system/partition has been created for the system audit data path. Check that a file system/partition has been created for the system audit data path with the following command: Note: /var/log/audit is used as the example as it is a common location. #grep /var/log/audit /etc/fstab UUID=3645951a /var/log/audit ext4 defaults 1 2 If a separate entry for "/var/log/audit" does not exist, ask the System Administrator if the system audit logs are being written to a different file system/partition on the system, then grep for that file system/partition. If a separate file system/partition does not exist for the system audit data path, this is a finding.

Verify that a separate file system/partition has been created for the system audit data path.

Check that a file system/partition has been created for the system audit data path with the following command:

Note: /var/log/audit is used as the example as it is a common location.

#grep /var/log/audit /etc/fstab
UUID=3645951a /var/log/audit ext4 defaults 1 2

If a separate entry for "/var/log/audit" does not exist, ask the System Administrator if the system audit logs are being written to a different file system/partition on the system, then grep for that file system/partition.

If a separate file system/partition does not exist for the system audit data path, this is a finding.
