摘要
在生物免疫系统中,通常是在自身免疫细胞数远远小于可能抗原的情况下,成功应对几乎所有抗原,这主要得益于抗体的多样性。论文分析了攻击特征组成上与抗原的相似性后,提出了"特征元素-特征因子-特征基-攻击特征"的多层次、多特征融合的特征表述方法;给出基于该方法的IDS特征提取与识别算法。该特征表述方法使检测器具有多样性,为检测器自适应进化奠定了基础。
In the biological immune system,immune cells usually succeed in dealing with nearly all antigens under the condition that its counts is far smaller than possible antigen oneself, this benefits from the variety of antibody mainly.This paper analyzes a similarity between attack characteristic and antigen,and then puts forward a new expression of signature with the multi-level ＆ multi-characteristic fuzzy with characteristic element,characteristic factor,characteristic base and intrusion pattern.The paper also provides algorithms of drawing and discerning IDS signature based on this expression.The expression inspired by varieties of antigen or antibody makes the intrusion detectors have variety,and more importantly,establish the foundation that the detection evolves.
