An Edge IDS Based on Biological Immune Principles for Dynamic Threat Detection

Table 3

The computing steps of negative selection and clone selection.

Step 1	Define a set (self) with equal-length strings. A single string generated randomly is divided into equal-sized substrings to generate .
Step 2	Obtain a set that does not match the elements in .
Step 3	Generate random situation in those strings with high weight. And starting from the situation, taking out equal length , the strings obtained will be duplicated.
Step 4	A random bite is chosen in these cloned string. The bite will be the mutation. Thus, an initial antibody population is obtained.
Step 5	Monitor by the detectors in . If any of the detectors matches a string in , then a normal attack is detected.
