All other ports are closed. My would someone open TACACS to the internet? I'm guessing this is a config error because all the authenticating devices would be on the inside of the network due to this being the perimeter device. If this was a PT what vectors would you have to exploit this open port? Looks like it is closed upon telnetting to anyway- however this could be due to the port looking for a certain response from a client????
