Biological Metaphor for Cyber Immunity

The human immune system consists of specific layers for organism protection, whose essential feature is to recognize all input entities as self versus non-self and to kill or destroy the last ones. All biological cells belonged to our body are saved in immune system’s “memory” as “self” entities and marked as “white-listed”. This type of entities provides special protein markers as their identification tool. Other entities which can not submit their protein marker are marked as “non-self” and will be destroyed by immune system further. The immunity work principle has helped to identify the biological metaphor which can be adopted to cybersecurity field in the way of appropriating the “immune memory” of reactions to as known as unknown previously cyber-attacks.
