Abstract
The network logon protocol used in a pass-through authentication request embedded in an encrypted network packet is identified. A protocol detection engine correlates events and network requests received at a domain controller in order to use the data contained in a correlated pair to determine a size of a challenge response in the encrypted network packet. The size of the response is used to identify the network logon protocol used in the pass-through authentication request.
