Vulnerability discussion

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without this notification, the security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected.Audit processing failures include software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded.This requirement applies to each audit data storage repository (i.e., distinct information system component where audit records are stored), the centralized audit storage capacity of organizations (i.e., all audit data storage repositories combined), or both.

Check content

Check /etc/audit/auditd.conf for the space_left_action with the following command: # cat /etc/audit/auditd.conf | grep space_left_action If the "space_left_action" parameter is missing; is set to "ignore", "suspend", "single", or "halt"; or is blank, this is a finding. Expected Result: space_left_action = SYSLOG NOTES: If the "space_left_action" is set to "exec", the system executes a designated script. If this script informs the SA of the event, this is not a finding. If the "space_left_action" is set to "email" and the "action_mail_acct" parameter is not set to the email address of the system administrator, this is a finding. The "action_mail_acct" parameter, if missing, defaults to "root". Note that if the email address of the system administrator is on a remote system, "sendmail" must be available.

Fix text

Set the space_left_action parameter to the valid setting "SYSLOG" by running the following command: # sed -i "/^[^#]*space_left_action/ c\space_left_action = SYSLOG" /etc/audit/auditd.conf Restart the audit service: # service auditd restart

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
