Certificate-Based and Smart Card Authentication in Active Directory

Implementing secure, passwordless authentication is critical for modern enterprise security, yet configuring certificate-based access can be highly complex and prone to post-patch failures. This text-based course guides you through the core concepts of Public Key Infrastructure (PKI) and smart card authentication, especially within isolated or highly secure networks. You will transition from understanding basic cryptographic concepts to confidently deploying, managing, and troubleshooting X.509 certificate authentication, ensuring compliance with modern security updates. What you'll learn: - Understand the foundational concepts of PKI, asymmetric cryptography, and X.509 certificate structures. - Configure Certificate Services for smart card enrollment and user mapping. - Deploy certificate-based authentication for users in standard and air-gapped environments. - Troubleshoot authentication failures, Kerberos errors, and patch-related strong certificate mapping issues. - Apply zero-trust principles to identity management and secure access controls. The course begins with essential terminology and PKI architecture before guiding you through step-by-step configuration processes and real-world troubleshooting scenarios for isolated networks. Designed for IT administrators and security beginners, this course requires no prior PKI experience and starts with the absolute fundamentals.
