Determine if the operating system is configured to have the "/var/log/audit" path is on a separate file system. # grep /var/log/audit /etc/fstab If no result is returned, or the operating system is not configured to have "/var/log/audit" on a separate file system, this is a finding. Verify that "/var/log/audit" is mounted on a separate file system: # mount \| grep "/var/log/audit" If no result is returned, or "/var/log/audit" is not on a separate file system, this is a finding. Verify the size of the audit file system: # df -h /var/log/audit If the size is insufficient for a week of audit data, this is a finding.

Determine if the operating system is configured to have the "/var/log/audit" path is on a separate file system.

# grep /var/log/audit /etc/fstab

If no result is returned, or the operating system is not configured to have "/var/log/audit" on a separate file system, this is a finding.

Verify that "/var/log/audit" is mounted on a separate file system:

# mount | grep "/var/log/audit"

If no result is returned, or "/var/log/audit" is not on a separate file system, this is a finding.

Verify the size of the audit file system:

# df -h /var/log/audit

If the size is insufficient for a week of audit data, this is a finding.

Fix Text (F-23460r419341_fix)
Migrate the system audit data path onto an appropriately sized separate file system to store at least one week of audit records.
