Overview of audit events generated by the Certification Authority

Author Uwe GradeneggerPosted on Categories Security, Certification AuthorityTags ,

The following is an overview of the audit events generated by the certification authority in the Windows Event Viewer.

In contrast to operational events, which are often understood under the term "monitoring", auditing for the certification authority is the configuration of logging of security-relevant events.

Event Sources

Audit events are always written to the security log. They always come from the Microsoft Windows Security Auditing source. The events relevant for the certification authority have the ID numbers 4868 to 4900.

Activate auditing

Audit events are not written until the certification authorities have been configured to do so. For a description of the procedure, see the article "Configuration of security event monitoring (auditing settings) for certification authorities„.

Enable extended audit events

Events 4898 to 4900 are generated only when a corresponding configuration setting (the flag EDITF_AUDITCERTTEMPLATELOAD) was set on the certification authority.

certutil -setreg policy\EditFlags +EDITF_AUDITCERTTEMPLATELOAD

Subsequently, a restart of the Certification Authority service is required to apply the settings.
