A chromosome-based evaluation model for computer defense immune systems

The computer defense immune system (GDIS) is an artificial immune system for detecting computer viruses and network intrusions. We present a simple chromosome-based evaluation model for GDIS. In this model, the genotype space is a linear number sequence, and a digital pattern sequence is produced as the phenotype space using a number of mechanisms, including pattern mining and genetic algorithms. We present a range of experiment analyses to show the higher efficiency and stronger immunity of this model, improving the rate of successful prediction in intrusion detection in GDIS. The detectors generated may have higher coverage, hence would impose lower communications and computational loads on systems in which they were incorporated.
