Title
The operating system must allocate audit record storage capacity. (Cat II impact)
Discussion
Operating system auditing capability is critical for accurate forensic analysis. Audit record content that may be necessary to satisfy the requirement of this control includes, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked. It is imperative the operating system configured, allocate storage capacity to contain audit records.
Check Content
The check displays the "% free" to leave available for the system. The audit system will not write logs if the volume has less than this percentage of free disk space. To view the current setting, run the following command: sudo grep minfree /etc/security/audit_control | awk -F: '{ print $2 }' If this returns no results, or an incorrect setting for the organization, this is a finding.
Fix Text
Edit the /etc/security/audit_control file, and change the value for "minfree" to the percentage of free space you require to keep available for the system. You can use the following command to set the "minfree" value to "10%": sudo sed -i.bak 's/.*minfree.*/minfree:10/' /etc/security/audit_control
