Abstract:
1. A method of securing a network comprising: providing, by a gatekeeper device, a monitored session between a first client in a first network and a first network resource in a second network, wherein the gatekeeper device monitors keystrokes entered at the first client and wherein the first client is authorized to communicate with the first network resource; determining, using a processor, and at least in part by evaluating at least one of a black list of prohibited commands and a white list of permitted commands, that the monitored keystrokes indicate an attempt by the first client to execute an unauthorized command, wherein the unauthorized command, when executed, attempts to cause an access, from the first network resource, of a second network resource; and taking, by the gatekeeper device, a remedial action, wherein the remedial action includes at least one of substituting the unauthorized command with a bogus command and preventing the first client from transmitting the unauthorized command to the first network resource.
