Abstract: On the basis of research for anomaly detection in the biological immune principles, a gene immune detection algorithm for anomaly detection is provided. Positive selection and vaccine mechanism are introduced on the premise of negative selection and clone selection in this algorithm. And a gene detection strategy of PRI is adopted by abstracting a computer’s DNA. This paper discussed the problem of anomaly detection in computer immune system roundly and deeply. Simulation experimental results show that the algorithm improves self-immunity and variety of antibodies. And its detecting efficiency is improved obviously
