Audit: Shut down system immediately if unable to log security auditsID: oval:org.secpod.oval:def:35408 | Date: (C)2016-06-10 (M)2023-12-13 |

This security setting determines whether the system shuts down if it is unable to log security events.
If this security setting is enabled, it causes the system to stop if a security audit cannot be logged for any reason. Typically, an event fails to be logged when the security audit log is full and the retention method that is specified for the security log is either Do Not Overwrite Events or Overwrite Events by Days.
If the security log is full and an existing entry cannot be overwritten, and this security option is enabled, the following Stop error appears:
STOP: C0000244 {Audit Failed}
An attempt to generate a security audit failed.
To recover, an administrator must log on, archive the log (optional), clear the log, and reset this option as desired. Until this security setting is reset, no users, other than a member of the Administrators group will be able to log on to the system, even if the security log is not full.
Note: On Windows versions prior to Windows Vista configuring this security setting, changes will not take effect until you restart Windows.
Default: Disabled.
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.
Fix:
(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
