Disable: 'Audit: Shut down system immediately if unable to log security audits' for crashonauditfail This policy setting determines whether the system shuts down if it is unable to log Security events. It is a requirement for Trusted Computer System Evaluation Criteria (TCSEC)-C2 and Common Criteria certification to prevent auditable events from occurring if the audit system is unable to log them. Microsoft has chosen to meet this requirement by halting the system and displaying a stop message if the auditing system experiences a failure. When this policy setting is enabled, the system will be shut down if a security audit cannot be logged for any reason. If the Audit: Shut down system immediately if unable to log security audits setting is enabled, unplanned system failures can occur. Therefore, this policy setting is configured to Not Defined for both of the environments that are discussed in this chapter. Counter Measure: Enable the Shut down system immediately if unable to log security audits setting. Potential Impact: If you enable this policy setting, the administrative burden can be significant, especially if you also configure the Retention method for the Security log to Do not overwrite events (clear log manually). This configuration causes a repudiation threat (a backup operator could deny that they backed up or restored data) to become a denial of service (DoS) vulnerability, because a server could be forced to shut down if it is overwhelmed with logon events and other security events that are written to the Security log. Also, because the shutdown is not graceful, it is possible that irreparable damage to the operating system, applications, or data could result. Although the NTFS file system guarantees its integrity when an ungraceful computer shutdown occurs, it cannot guarantee that every data file for every application will still be in a usable form when the computer restarts.


Technical Mechanism: (1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Audit: Shut down system immediately if unable to log security audits (2) REG: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\crashonauditfail
