Monitoring network traffic received by domain controllers for specific LDAP queries can provide for the detection of adversary activity. Active Directory does not provide a mechanism for logging the exact queries received, but some degree of profiling and monitoring for access to specific attributes can be achieved using Event ID 4662 in the subcategory Audit Directory Service Access. Because of the high volume, it is difficult to separate an adversary’s queries from the normal operations of the environment. LDAP is one of the more frequently used protocols within Active Directory.
