A system for monitoring attempted intrusions into a secure private network (SPN) includes a transceiver adapted to receive a device identifier over a public network from a network node, the device identifier based on a user-configurable parameter and a non-user-configurable parameter of the network node, and a processor coupled to the transceiver and to memory storing executable code. When executed, the code enables the processor to: access a database of authorized device identifiers corresponding to known network nodes, allow, in response to the received device identifier matching one of the authorized device identifiers, the network node to access the SPN, deny, in response to the received device identifier not matching one of the authorized device identifiers, the network node from accessing the SPN and categorize a connection attempt as an unauthorized connection attempt, and store information regarding the unauthorized connection attempt in local or remote memory.
