Securing AD CS: Preventing Privilege Escalation in Certificate Templates

Active Directory Certificate Services (AD CS) is a powerful tool, but misconfigured certificate templates can accidentally grant regular users domain administrator privileges. Understanding how to properly configure permissions—especially for enterprise services like SCOM—is critical for securing your infrastructure against modern identity attacks. This text-only course guides you through the fundamentals of PKI security, certificate template permissions, and how to prevent common privilege escalation paths. You will learn to audit your templates, configure secure access controls, and apply modern hardening techniques to protect your Active Directory environment. What you'll learn: - Understand the core concepts of Active Directory Certificate Services and certificate-based authentication. - Identify high-risk template misconfigurations, including over-privileged "Read" and "Enroll" permissions. - Analyze how attackers exploit weak certificate templates to escalate privileges to Domain Admin. - Configure secure enrollment permissions specifically for SCOM and other enterprise monitoring services. - Implement modern PKI hardening strategies and zero-trust principles to secure your certificate infrastructure. - Audit existing Active Directory certificate templates to find and remediate hidden security vulnerabilities. Starting with fundamental PKI concepts and terminology, this course builds your knowledge up to advanced template security and auditing techniques. You will read through clear explanations, configuration examples, and step-by-step remediation workflows. This course is designed for system administrators, security analysts, and IT professionals looking to secure their Active Directory environments. No prior PKI security experience is required.
