Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
A special HTTP server runs outside the protected network and a client program is run on a computer inside the protected network. Whenever any network traffic is passed from the client, the client repackages the traffic data as a HTTP request and relays the data to the outside server, which extracts and executes the original network request for ...
Port knocking is totally dependent on the robustness of the port knocking daemon.
