Description

Active Directory – Authentication Course. This course examines the authentication mechanisms in Active Directory, with a primary focus on the NTLM and Kerberos protocols, along with their inherent vulnerabilities and methods for securing them. Authentication is considered the foundation of Windows security, and this course provides a comprehensive analysis that fills a common knowledge gap among IT professionals. Course content includes the operation of the NTLM protocol and the challenge-response mechanism, vulnerabilities in NTLMv1, and full details of the Kerberos protocol, including ticketing, cryptographic fundamentals, and common attack techniques for breaching Active Directory environments. It also analyzes the weaknesses of these protocols and the methods used by attackers to exploit them, and provides practical solutions for securing them. Topics such as the risks of Kerberos delegation, its types, and the conditions under which security threats arise are also covered. A large portion of the course is dedicated to implementing security best practices, including implementing AES encryption, properly configuring Kerberos authentication policies, setting protected user attributes, and enforcing delegation restrictions. In the context of common attacks, the course describes attacks such as Kerberos spoofing and provides effective defenses to mitigate risk. Finally, by leveraging actionable insights from security audits and providing industry-proven best practices, this course empowers IT administrators, security professionals, and Windows engineers to fully understand the inner workings of authentication, identify security gaps, and harden their Active Directory infrastructure.
