Fix Recommendation

Modify DBMS, OS, or third-party logging application settings to alert appropriate personnel when a specific percentage of log storage capacity is reached.

If EDB Postgres Enterprise Manager (PEM) is in use, it may be configured to issue an alert, send an email to designated personnel, and shut down the EDB Postgres Advanced Server instance when the audit log mount point is at 99 percent full. Refer to the Supplemental Procedures document, supplied with this STIG, for guidance on configuring PEM alerts.

Check Contents

If Postgres Enterprise Manager (PEM) is installed and configured to shut down the database when the audit log is full, this is not a finding.

Otherwise, review the procedures, manual and/or automated, for monitoring the space used by audit trail(s) and for off-loading audit records to a centralized log management system.

If the procedures do not exist, this is a finding.

If the procedures exist, request evidence that they are followed. If the evidence indicates that the procedures are not followed, this is a finding.

If the procedures exist, inquire if the system has ever run out of audit trail space in the last two years or since the last system upgrade, whichever is more recent. If it has run out of space in this period, and the procedures have not been updated to compensate, this is a finding.
