A system and method to track external devices attempting to connect to a protected network using probabilistic filters. When a connection from a new external device attempts to access the protected network, the memory of a protection system, which is organized as a probabilistic filter, is searched to determine if the IP address already exists in the memory of protection system. If the search locates the IP address, the protection system terminates the connection to the external device. If the search is negative, then protection device begins the authentication process for the external device.
