Human^ machine competitive Introduction Simple Human competitive Human^ machine competitive
Unfortunately, most computer viruses are not so courteous!
Threat numbers show the story of what’s happening?
These are Commercial Software… Norton AV Command AV McAfee AV Chernobyl-1.4 Not detected F0sf0r0 Hare Z0mbie-6.b 468% increase in malware attacks from 2006-2007 Signature matching! Size of signature database cannot scale! Inability to detect zero-day (novel) attacks!
Motivation for current work A self-healing, self-defending and living artificial immune system Proactive defense against zero-day attacks Mapping concepts from A-life and evolution
Immune inspired Network Intrusion Detection System Alarm Output Adaptive Immune System/ Innate Immune System Negative Selection Dendritic Cell Algorithm Intelligent Statistical Features Memory of Markov Chain Multi resolution session rate Entropy of IP address Divergence of port distribution Network Traffic Stream

Engineered System Patent pending Complete version will be ready in 1 year time; free download US$200,000 grant to develop the final product from the National ICT R&D fund, Government of Pakistan
Why the best? In a nutshell… 1. Hard problem in hard domain; impossible for a human to solve 2. Evolved system better than human developed, commercial anti-virus software 3. Evolved system better than state-of-the-art statistical malware detectors 4. Hybrid of statistical-immune detectors; best of both worlds 5. Engineered product; open-source initiative
