    <SYSTEMREMOTECLIENT> as threat source process name?


      Does anyone know what <SYSTEMREMOTECLIENT> means when it is in the threat source process name field in an IPS event? Is there any good way to create exceptions for these? I have tried with little success to create an exception for such an event. Here is the event in question (sensitive data X'ed out). The threat source process hostname and IP is the same as the threat source process hostname and IP.

          <SYSTEMREMOTECLIENT> is the remote system's SYSTEM account process.  I tested a (custom) signature that uses this process name and wrote an IPS exception for it (created it straight from the ePO event), and it worked fine.
