Abstract
Embodiments are directed toward transparent denial of service protection. Instruction set information that references a seed file may be communicated to a client computer. A network packet key may be generated based on the instruction set information or encrypted and provided by a server. A client computer may generate a client network packet key based on the instruction set information provided by the network computer and a seed file installed on the client computer. The client computer may include the client network packet key the one or more network packets that it is sending to the network computer before they are provided to the network computer. A packet rule that includes the network packet key may be generated and installed in a packet inspection engine. If network packets are received, the packet inspection engine compares the network packet key to the network packets using the packet rule.
