10. A method for detecting and defeating unauthorized intrusion within a computer network of an infrastructure element of a high value target, the method comprising: receiving data from the computer network of the infrastructure element of the high value target; filtering the received data; applying grammars produced with a grammar based compression and learning algorithm to the filtered data; expanding a sampling of the filtered data, after the grammars have been applied, with polymorphic transformation; analyzing the expanded sampled data to determine the unauthorized intrusion; and recommending whether the unauthorized intrusion has occurred occurs based on the analyzed data.
