Certificate issued to Privileged User
This rule detects when a certificate is issued to a privileged user. It identifies privileged users by checking their group membership against a predefined list of administrative groups such as 'Domain Admins', 'Enterprise Admins', and 'Administrators'. The rule then looks for Windows Security Event ID 4886, which indicates a certificate services operation, and extracts the principal name from the Subject Alternative Name field. Finally, it joins this information with the identified privileged users to flag any certificate issuance to them.
