17. A non-transitory computer-readable media comprising routines which are executed on a processor for detecting and defeating an unauthorized intrusion within a computer network of an infrastructure element of a high value target, the non-transitory computer-readable media configured for: receiving data from the computer network of the infrastructure element of a 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 based on the analyzed data.
18. The non-transitory computer-readable media according to claim 17 , further configured for: expanding the sampled filtered data using an application of distance metrics, hierarchical processing and ranking, and/or fuzzy models; and estimating Kolmogorov complexity which forms compressive grammar based on Minimum Description Length principles as part of the grammar based compression and learning algorithm.
