The operating system must take organization-defined actions upon audit failure (e.g., shut down information system, overwrite oldest audit records, stop generating audit records).

Description
It is critical when a system is at risk of failing to process audit logs, as required, it detects and takes action to mitigate the failure. Audit processing failures include, software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded. In order for the audit control system to shut down when an audit processing failure occurs, the setting "ahlt" must be configured. The default setting is "cnt" which allows the system to continue running in the event of an audit processing failure.
