MongoDB must provide an immediate real-time alert to appropriate support staff of all audit log failures.

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. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected. The appropriate support staff include, at a minimum, the information system security officer (ISSO) and the database administrator (DBA)/system administrator (SA). 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. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).

ℹ️ Check
MongoDB database halts if it cannot write audit events to the audit log due to insufficient storage on the volume where the audit log is being written. Check the operating system or third-party logging software settings to determine whether a real-time alert will be sent to the appropriate personnel when the volume hosting the MongoDB audit log is nearing capacity. If real-time alerts are not set up to monitor the remaining storage capacity of the volume hosting the MongoDB audit logs, this is a finding.

✔️ Fix
Setup and configure real-time alerts by configuring OS or third-party software monitoring tools to notify appropriate personnel when the storage allocation on the volume hosting the MongoDB audit logs usage reaches a predefined site specific threshold.
