Abstract: A network security system protects a computer network by evaluating all incoming data packets with one or more triggers to determine whether the incoming data packets are suspect data packets or acceptable data packets. The system changes the triggers and sensors that incoming packets encounter according to a programmable schedule, which makes attackers confused and uncertain about the network. When suspect data packets are encountered, the system performs one or more protective actions with respect to the suspect data packet. Some of these actions include logging, allowing, delaying, blocking, redirecting, and trapping the suspect data packets.

Abstract: A network security system and method is disclosed that ensures that only authorized devices can communicate with a protected computer network. The network security system has one or more processors configured to execute computer-executable instructions and memory storing computer-executable instructions that are written to implement a security device having a monitor module and at least one monitoring port configured to receive an access request from a remote device comprising a sequence of network port calls. The monitor module then verifies the sequence and provides the remote device with access to a port to communicate with the protected computer network or denies the access if the provided sequence of port calls is incorrect.

Abstract: A system and method of regulating network traffic based on information about packets is disclosed. Network traffic from undesirable countries, companies, and regions, for example, can be blocked with the click of a mouse. The system employs an appliance, a server and a computer with a user interface from which it can be controlled.
