What PTA detections require the deployment of a Network Sensor or the installation of the PTA Agent on the domain controller?

The requirement for deploying a Network Sensor or installing the PTA Agent on the domain controller is specifically tied to the detection of sophisticated types of attacks like Over-Pass-The-Hash and Golden Ticket. These detection methods are critical because they involve advanced techniques used by attackers to gain unauthorized access to network resources while leveraging stolen credentials.

Over-Pass-The-Hash is a method where attackers use a hash of a password to create a new authentication ticket, bypassing the need for the plaintext password. Golden Ticket attacks involve forging Kerberos tickets that allow attackers to access any service in the domain without needing to authenticate against the actual password. Both of these methods of attack can go undetected if not monitored correctly, thus making the implementation of a Network Sensor or PTA Agent essential. This allows for real-time monitoring of authentication processes and detection of anomalies indicative of these types of attacks.

The other options, while they may represent legitimate threat scenarios, do not specifically necessitate the deployment of these particular tools for detection in the same manner. Credential re-use and password guessing, for instance, can often be flagged using simpler monitoring tactics, while unauthorized access and session abuse might involve more general logging and alerting mechanisms rather than the specific deployment required for advanced Kerberos-based studies.
