Why you need to move from "Audit" to "Enforced" to stop Kerberos relay attacks.
This led to the infamous scenario, where an attacker could impersonate a privileged user simply by presenting a certificate with a spoofed SAN. The Fix: Strong Certificate Binding Enter Strong Certificate Binding . strongcertificatebindingenforcement
Look for (KDC_ERR_CERTIFICATE_MISMATCH) and Event ID 41 (Weak mapping fallback). These events tell you exactly which accounts will break when you enforce strong binding. Why you need to move from "Audit" to
The problem is the fallback . If the DC can't find the strong binding (perhaps due to an old certificate or a misconfigured attribute), it happily accepts the weak mapping. Attackers specifically craft their exploits to trigger that fallback path, bypassing strong binding entirely. If the DC can't find the strong binding
If you manage a hybrid or on-premises Active Directory environment, you’ve likely seen the registry key StrongCertificateBindingEnforcement while auditing Group Policy settings or scanning through Microsoft security baselines.
