DETECTION OVERVIEW
Risk Factors
Enumeration is a simple but important step taken by attackers after an initial network compromise. Attack tools make enumeration relatively easy to perform. Enumeration activity typically does not negatively affect network performance, but attackers can leverage this information to find new targets in an attack campaign.
The system might change the risk score for this detection.

37
After infiltrating a network, an attacker might connect to a directory server such as Active Directory (AD) to learn about the directory objects such as users, services, and workstations. One method for enumerating many objects is querying an AD server over LDAP. LDAP enables administrators to search for, create, or modify objects on a directory server. The attacker sends an LDAP query request with the asterisk (*) wildcard character, which identifies any object associated with a single attribute, such as objectClass, samAccountName, or distinguished name (DN). The attacker can then target these objects for additional attacks.
Implement the least privilege model for accessing LDAP domain objects to reduce the information users can enumerate through scans and help minimize unnecessary reads or writes to certain objects
Because securing LDAP servers can be difficult without compromising functionality, monitor and investigate unusual LDAP activity quickly to minimize potential damage
