Enumeration and Post-Enumeration Attack on Active Directory and Their Detection Using log Correlation Method

Microsoft Active Directory Domain Services (AD DS) is a cornerstone of IT infrastructure in many organizations due to its widespread use and comprehensive feature set. AD DS centralizes network management, streamlines user authentication, and simplifies access control, thereby enhancing the efficiency of IT operations. However, its ubiquity and critical role also make it a prime target for attackers. This study delves into the Kerberos authentication protocol, which is often exploited in various attacks on AD DS. It investigates techniques used for enumeration and post-enumeration activities in AD environments and proposes strategies for detecting and mitigating these security threats. Furthermore, an experimental setup has been developed to demonstrate examples of these attacks. Addressing the challenge of detecting and thwarting enumeration and post-enumeration attacks is crucial, as it is vital to intercept attackers during the early stages of their attempts. This resource aims to be a comprehensive guide for IT security professionals managing Microsoft AD environments, providing essential insights into securing their systems against such threats.
