What it detects

This rule detects changes to the StrongCertificateBindingEnforcement or SCHANNEL CertificateMappingMethods registry values that govern how certificates map to Active Directory accounts. Downgrading these controls re-enables weak certificate mapping abused in ADCS impersonation attacks. Relaxed binding lets a forged or requested certificate authenticate as a privileged account.
