Title: The DBMS itself, or the logging or alerting mechanism the application utilizes, must provide a warning when allocated audit record storage volume reaches an organization defined percentage of maximum audit record storage capacity.
Vulnerability ID: V-32377
IA Controls: None
Description: It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Audit processing failures include: software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded.
If audit log capacity were to be exceeded then events subsequently occurring will not be recorded. Organizations shall define a maximum allowable percentage of storage capacity serving as an alarming threshold (e.g., application has exceeded 80% of log storage capacity allocated) at which time the application or the logging mechanism the application utilizes will provide a warning to the appropriate personnel.
A failure of database auditing will result in either the database continuing to function without auditing or in a complete halt to database operations. When audit processing fails, appropriate personnel must be alerted immediately to avoid further downtime or unaudited transactions. This can be an alert provided by the database, a log repository, or the OS when a designated log directory is nearing capacity.
Check Text: Review DBMS, OS, or third party logging application settings to determine whether a warning will be provided when a specific percentage of log storage capacity is reached. If no warning will be provided, this is a finding.
Fix Text: Modify DBMS, OS, or third party logging application settings to alert appropriate personnel when a specific percentage of log storage capacity is reached.[divider]
