Abstract
Systems and methods for protecting a network including preventing data traffic from exiting the network unless a domain name request has been performed by a device attempting to transmit the data traffic. In an embodiment, a device within the protected network attempting to send data outside the protected network requests an address for a destination outside the protected network from a domain name server (DNS). In response, the DNS provides an address of the destination to the device and a gateway. In response to receiving the address, the gateway temporarily allows access to the address. In an embodiment, a DNS is coupled to a protected network and the gateway, the DNS provides an external address to a device in response to a request; and a mapping to the gateway; the gateway, coupled to a protected network and an external network, allows traffic according to the mapping.
