Abstract

A system and method for providing a network host decoy on a virtual host using a pseudo implementation of a network protocol stack are described. A hierarchical network protocol stack is functionally defined and includes a plurality of communicatively interfaced protocol layers. A request frame originating from a remote host is received. The request frame includes a plurality of recursively encapsulated data segments which each correspond to a successive protocol layer in the network protocol stack. At each protocol layer, processing a header associated with the encapsulated data segment demultiplexs each encapsulated data segment in the request frame. Any requested network service is performed and any recursively encapsulated portion is forwarded to the next successive protocol layer. A plurality of pseudo data segments corresponding to each of the protocol layers in the network protocol stack is formed. Each pseudo data segment includes a header and data portion. The header includes network protocol stack characteristics for a pseudo host different than the network protocol stack characteristics for the virtual host. Each of the pseudo data segments within a response frame is recursively encapsulated. A network address for the pseudo host different than the network address for the virtual host is inserted into the response frame. The response frame is sent to the remote host.
