A system for and method of securing a network are described herein. A receiving device listens for packets with proper credentials. If a transmitting device sends the correct credentials, the receiving device will respond with an acknowledgment and further data is able to be transmitted. However, if the transmitting device does not send a packet with the proper credentials, then the receiving device will drop the packet and not respond. Thus, the transmitting device will be unaware of the presence of the receiving device, in particular when hackers are using scanning software to locate target devices.
